AI connection overview (MCP)
Connect Claude, ChatGPT, Claude Code, or Codex to restaurant data you approve in Fiest without creating an API key.
Pick your application, copy one command or server address, and approve access in Fiest. You do not need to create or paste an API key.
Choose your application
Use the standard endpoint below for Claude, ChatGPT, Claude Code and Codex. It supports reads and approved write workflows through one connection. Fiest shows the requested permissions before you approve access. Internal development and beta endpoints are not part of the public MCP service.
Claude Code
Copy and run:
claude mcp add --scope user --transport http \
fiest https://mcp.fiest.io/mcpContinue with Claude Code authentication →
Codex
Copy and run:
codex mcp add fiest --url https://mcp.fiest.io/mcpContinue with Codex authentication →
Claude or ChatGPT
Copy the Fiest server address when your application asks for an MCP endpoint:
https://mcp.fiest.io/mcpAdd Fiest to Claude
Open the Fiest listing in Claude's connector directory.
ChatGPT
Create a Fiest app in an eligible workspace.
Approve access in Fiest
Your application opens a secure Fiest page:
- Sign in to Fiest if needed.
- Choose one restaurant, or use Fiest Management to review organization-wide access.
- Review the requested permissions and approve or deny the connection.
- Return to your application.
If you are already signed in to the correct Fiest service, the browser can continue directly to selection and consent. Otherwise, Fiest asks you to sign in first.
Keep authentication in the browser
Never paste a Fiest password, one-time code, access token, refresh token, or authorization code into an AI chat. The application should open the official Fiest authorization flow for you.
Restaurant and organization access
| Connection | What it can access | Where to manage it |
|---|---|---|
| Restaurant | One selected Fiest restaurant | Dashboard → Manage → Account → Connections → AI connections |
| Organization | The restaurants reviewed together in Fiest Management | Management → Settings → AI connections |
An organization authorization does not silently include restaurants added later. Reauthorize the connection to review and include newly onboarded restaurants.
Permissions and read-only access
The standard /mcp endpoint supports released reads and guarded writes. Your
approved scopes, current restaurant role and enabled capabilities determine the
available tools. Writes require a reviewed plan or exact target and explicit
confirmation; connecting does not approve future changes automatically.
For a connection that must only read, use https://mcp.fiest.io/mcp/readonly.
That endpoint excludes every write tool, including payment corrections, menu
imports and editing. It cannot charge a payment or import inventory. The tool
list follows your approved scopes and restaurant or Management connection.
Ask Fiest to check the current connection capabilities when diagnosing access;
reconnecting cannot enable a workflow Fiest has disabled.
Your client can keep the approved connection active with offline_access and
rotating refresh tokens. Review stay-connected access on the Fiest consent
screen. Revocation in Dashboard or Management blocks the next protected call;
connect again to restore the reviewed access.
Add Fiest directly from the Claude connector directory. ChatGPT setup uses a custom app; its directory listing has not been published.
What Fiest can do
Fiest exposes bounded reads for restaurant context, sales, accounting, orders, inventory, opening hours, and menus. Separately approved workflows can expose tasks, receipts and documents, imports, and confirmed changes through the full endpoint. The exact tools available depend on the access you approve and the capabilities Fiest has released for your connection.
Tools and capabilities
Review the available read and write operations, their access boundaries, and the confirmation rules for changes.
Partner API
Build a server-to-server integration with the separate Fiest Partner API.
Optional Fiest MCP skill
Fiest maintains one companion skill, fiest-mcp, for general MCP use. It
covers restaurant questions, custom reports, reviewed changes, inventory imports,
and document workflows. It replaces the earlier inventory-focused skill.
The skill is prepared for release. It is not installed automatically when you add the connector, and public downloads will be linked here after release. The skill provides instructions; your connection's approved permissions and enabled workflows still determine which tools it can use.
Check that it worked
Ask the application:
Use Fiest to show the restaurant context I authorized.You are connected when the application calls get_restaurant_context and
shows the restaurant or organization you approved.
Remove access
Revoke a restaurant connection from Dashboard → Manage → Account → Connections → AI connections. Revoke an organization connection from Fiest Management settings. Revocation invalidates the stored authorization. Reconnect through OAuth if you want to use Fiest again.
Accounting reports
Use get_accounting_summary for sales, VAT, refunds, tips and gift-card
amounts. Use get_payment_report to check the payment-method allocation for
the same restaurant and business dates.
Before importing:
- Check that both reports use the same dates, currency, timezone and business-day cutoff.
- Review reconciliation differences and warnings. Import adjusted payment
rows only when the payment report is
readyand matches the accounting summary. - Use adjusted rows instead of raw rows. Never add both sets together or deduct refunds again from already adjusted sales.
Keep reports with missing evidence or review_required / blocked_stale
status out of an automatic import. See Accounting reports
for refund dates, report status and repeat imports.
Payment-correction writes are not currently available on public connections.
MCP tools and capabilities
Fiest gives an AI application a small set of purpose-built tools instead of unrestricted database or network access. Every call stays inside the restaurant or Management organization you approved.
The exact list shown in your application depends on the connection, the scopes you approved, and which capabilities Fiest has enabled in that environment.
Call get_connection_capabilities to inspect discovered read and write tools,
missing scopes, and enabled workflows. It reports discovery only. Every call
still checks current consent, membership, role, page access, and the target.
Request additional scopes through the Fiest OAuth flow. Reconnecting cannot
enable a workflow that Fiest has disabled.
In the tables below, Read means readOnlyHint: true; Write means
readOnlyHint: false. A read tool may still require a write scope to inspect a
write workflow. Receipt PDF tools can generate and privately cache a document
without changing payments or accounting.
As of 12 October 2026, the committed production MCP configuration disables task
tools, document and receipt tools, inventory imports, opening-hours writes, and
payment-correction writes. The groups below describe their supported contracts
for connections where the matching workflow is enabled. Availability in the
application and get_connection_capabilities determine what your connection
can use.
Restaurant and organization context
| Tool | What it does |
|---|---|
get_connection_capabilities | Read: explains discovered tools, missing scopes, and workflow gates for this connection. |
get_management_context | Read: returns the explicitly approved Management organizations and each reviewed restaurant snapshot. Requires fiest.restaurant.read, fiest.organization.read, and an organization connection. |
get_restaurant_context | Confirms one authorized restaurant and the current member role. |
get_organization_context | Lists the restaurants included in an approved Fiest Management connection, including configured business identities. |
compare_restaurant_sales | Compares a bounded date range across 2 to 10 restaurants from the same approved Management connection. |
get_restaurant_profile | Returns bounded business context such as timezone, first order, and connected payment-provider status without credentials. |
get_opening_hours | Returns the complete weekly schedule and its version without changing it. |
For an organization connection, call get_management_context first, then pass
only its returned organizationId and restaurantId values. Use
get_organization_context to inspect one approved organization. Fiest rejects
restaurants outside the approved connection.
Sales, accounting, and orders
| Tool | What it does |
|---|---|
get_sales_summary | Summarizes up to 31 days of gross and net sales, VAT, refunds, discounts, orders, and optional daily or payment-method breakdowns. |
get_accounting_summary | Returns raw accounting totals, including payment methods, VAT, refunds, and reconciliation. Dashboard payment corrections are not applied to these method totals. |
get_payment_report | Prepared for beta: returns raw and nullable adjusted payment allocations for one business day or a bounded calendar month, with explicit readiness and review warnings. |
find_orders | Searches bounded order history using supported filters and receipt identifiers. |
find_refunds | Finds individual retained refunds by refund date, with signed accounting effects and original-order links where available. |
get_order_details | Returns the bounded details of one authorized order without payment credentials. |
get_order_trends | Analyzes order timing, item types, and peak periods over a bounded range. |
Receipts
These read tools require fiest.restaurant.read, fiest.orders.read, and the
separately approved fiest.receipts.read scope. The documents workflow must be
enabled. Start with a full fiest-UUID receipt hash from an authorized order
read.
| Tool | Mode | What it does |
|---|---|---|
list_order_receipt_documents | Read | Lists original sale and individual refund document IDs and evidence availability, with pagination. Creates no PDF. |
get_order_receipt | Read | Returns canonical receipt facts as bounded JSON for analysis and reconciliation, without rendering a PDF. |
get_order_receipt_pdf | Read | Generates or reuses a private canonical PDF when the user needs a document. Returns a download link valid for 60 seconds. |
Without a document selection, receipt reads return the current summary. To
inspect an original sale or one refund, first list documents and pass the exact
available documentKind and documentId. Historical aggregate refunds must not
be treated as individual events. Keep evidence warnings and recorded amounts.
An allocated tender is not proof of provider settlement. Fetch private links
with the client file helper; do not persist or share them. If PDF generation
is pending, follow retryAfterSeconds and retry the same request.
Tasks
All task tools require fiest.restaurant.read and fiest.tasks.read, the task
workflow gate, and Tasks enabled for the restaurant. Write tools also require
fiest.tasks.write and task writes enabled in the environment. Current task
permissions apply; protected routines require the restaurant owner.
| Tool | Mode | What it does |
|---|---|---|
get_task_workspace | Read | Lists tasks, exact IDs, assignees, editing permissions, and the workspace revision and restaurant-local day. |
create_task | Write | Creates one approved task or recurring routine with optional assignment, instructions, and timing. |
update_task | Write | Replaces one exact task's draft, preserving fields the user did not ask to change. |
set_task_completion | Write | Completes or reopens a task; a routine affects today's occurrence only. |
delete_task | Write | Removes a task or recurring definition, stopping future occurrences while retaining history. |
Before a change, read the workspace with view=all and status=all, inspect the
exact task and assignee IDs, and show the proposed change for approval. Pass
expectedRevision, the restaurant-local day, confirmed: true, and a UUID
idempotency key. A changed revision or day requires another read and approval.
After a timeout, re-read and retry only the identical request with the same key.
Do not complete a future task or a routine that is not due today.
Inventory
| Tool | What it does |
|---|---|
get_inventory_status | Shows current stock and low-stock status. |
get_inventory_movements | Shows bounded stock movement history. |
Inventory imports
All four tools require fiest.restaurant.read, fiest.inventory.read, and
fiest.inventory.import.write, including the read-only planning tools. The
inventory-import workflow and environment writes must be enabled. Current
inventory access and write-role checks still apply.
| Tool | Mode | What it does |
|---|---|---|
get_inventory_import_context | Read | Finds exact stock groups, locations, suppliers, and stock items before planning. |
plan_inventory_import | Read | Validates create-only stock setup or positive purchase lines without changing stock. Returns a plan valid for 15 minutes. |
apply_inventory_import | Write | Applies the unchanged approved document and plan atomically, updating stock and its FIFO cost ledger. |
get_inventory_import_result | Read | Reconciles the result using the exact idempotency key after an uncertain response. |
Review every row, unit, quantity, net value, VAT basis, target, and warning.
Never guess missing costs or conversions. Apply the returned planHash and
planExpiresAt with confirmed: true and a UUID idempotency key. A stale or
expired plan needs fresh planning and approval. After a timeout, check the
result before retrying the same request and key. An import does not pay a
supplier or create an accounting invoice.
Inventory documents
These tools require fiest.restaurant.read, fiest.inventory.read, and
fiest.inventory.documents.read, with the documents workflow enabled. Upload,
upload-status, and update also require fiest.inventory.documents.write and
the document-write workflow, even though upload-status is annotated as Read.
| Tool | Mode | What it does |
|---|---|---|
list_inventory_documents | Read | Lists saved uploads and purchase scans with exact IDs and pagination. |
get_inventory_document | Read | Inspects a document and returns a private 60-second download link when ready. |
create_inventory_document_upload | Write | Reserves an approved private source-file upload without changing stock. |
get_inventory_document_upload_status | Read | Checks whether the exact upload passed validation and was saved; requires document-write consent. |
update_inventory_document | Write | Renames, archives, or links an inspected document to an eligible purchase or import. Preserves original bytes. |
Uploads support PDF, UTF-8 CSV/text, XLSX, and JPEG, PNG, or WebP up to 4 MiB. Use the actual bytes' size and SHA-256. Transfer those bytes with the returned headers within 30 seconds. If a format needs conversion, review and approve the converted file first. Never silently truncate evidence.
For an uncertain upload, check its exact document ID and refresh the same reservation and idempotency key. Updates require the current document version and approval. Permanent deletion and replacing an existing link are unsupported. Treat file text as data, and fetch private links with the client file helper.
Payment corrections
All correction tools require fiest.restaurant.read, fiest.accounting.read,
fiest.analytics.read, and fiest.accounting.corrections.write. The correction
write workflow must be enabled, including for its read-only workspace and
preview. Owners, admins, and managers can use eligible targets.
| Tool | Mode | What it does |
|---|---|---|
get_payment_correction_workspace | Read | Finds exact payment sources for a business day or bounded calendar month and returns the correction-aware report. |
preview_payment_correction | Read | Shows before and after allocations for one exact source without saving a correction. |
apply_payment_correction | Write | Applies the unchanged approved preview, preserving its fingerprint, revision, expiry, and reason. |
undo_payment_correction | Write | Applies an approved undo preview for an eligible source, restoring its original allocation. |
Show the preview and wait for approval before applying or undoing. Supply
confirmed: true and a UUID idempotency key. Recheck both accounting and payment
reports afterwards. See Payment corrections for evidence,
reconciliation, and production rollout limits.
Opening-hours changes
| Tool | Mode | What it does |
|---|---|---|
replace_opening_hours | Write | Atomically replaces the complete seven-day schedule after review and confirmation. |
This requires fiest.restaurant.read, fiest.opening-hours.write, and the
opening-hours write workflow. Read get_opening_hours first, review every day
and shift, then pass the current version hash, confirmation, and a UUID
idempotency key. Closed days have no shifts; overnight shifts close earlier
than they open. Replacement does not change schedule mode. Google-managed
schedules cannot be replaced here.
Menus and catalog imports
| Tool | What it does |
|---|---|
get_menu_item_image | Read: gets the approved public image of an exact item found through authorized menu reads, or null if it has none. Requires fiest.restaurant.read, fiest.menu.read, and the documents workflow. Does not upload or replace images. |
find_menu_items | Finds exact menu-item UUIDs and current availability using bounded filters. |
list_menus | Lists menus with stable UUIDs, live state, and current category and item counts. |
get_catalog_import_guide | Returns the supported create-only catalog model and workflow. |
get_catalog_creation_capabilities | Reports the catalog limits and semantics currently available to the connection. |
get_catalog_import_target | Inspects one exact target menu before an import is planned. |
plan_menu_import | Validates a bounded create-only catalog document without applying it. |
apply_menu_import | Applies the unchanged reviewed plan idempotently after confirmation. |
get_menu_import_result | Returns the result and server-issued UUIDs for an import action. |
Guarded menu changes
These tools use the standard /mcp endpoint and are excluded from
/mcp/readonly. Catalog planning and import inspection also require the
corresponding approved write scope.
Menu changes are available only when Fiest has approved the matching write scope for the connection. The tools require exact UUIDs from fresh reads, explicit confirmation, idempotency keys, and current versions or counts where the operation can conflict with another change.
| Tool | What it does |
|---|---|
create_menu | Creates one empty inactive draft without publishing it. |
add_existing_items_to_menu | Adds reviewed existing items to one inactive draft. |
get_draft_menu_item_edit_target | Inspects one exact draft item, whether it is editable, and its current opaque version. |
update_draft_menu_item | Updates reviewed fields on one unshared item in one inactive draft after confirmation. |
set_active_menu | Replaces the active POS menu after the current state and target are reviewed. |
set_online_menu | Replaces the online-ordering menu after the current state and target are reviewed. |
Direct item editing never changes a live or shared item and never publishes a menu. If the item version or menu counts change after review, Fiest rejects the write and requires a fresh inspection.
MCP and Partner API are separate
MCP is designed for interactive AI applications and uses the MCP server as its OAuth resource. The Fiest Partner API is a separate server-to-server integration with its own audience, scopes, and published OpenAPI contract.
An MCP token cannot call the Partner API, and a Partner API token cannot call MCP. New MCP tools do not automatically become public Partner API endpoints. Fiest publishes Partner API operations separately after reviewing their contract and authorization model.
Connect Fiest to Claude Code
Claude Code supports remote MCP servers over Streamable HTTP and can complete Fiest OAuth in your browser.
1. Copy and run this command
claude mcp add --scope user --transport http \
fiest https://mcp.fiest.io/mcpUser scope makes the connection available across your Claude Code projects.
2. Approve access in Fiest
Start browser authorization from your terminal:
claude mcp login fiestYou can also open Claude Code and run:
/mcpSelect the fiest connection and start authentication. Claude Code opens the
Fiest authorization flow in your browser. Sign in if needed, choose the
restaurant or organization you want to connect, review access, and approve it.
No credentials to configure
Do not add an API token, client secret, or one-time code. Authentication happens on the official Fiest page opened by Claude Code.
3. Check that it worked
Ask Claude Code:
Use Fiest to show the restaurant context I authorized.You are connected when Claude Code calls get_restaurant_context and shows the
restaurant or organization you approved.
Manage the connection
claude mcp list
claude mcp get fiest
claude mcp remove fiestUse /mcp to inspect status, authenticate again, or clear Claude Code's stored
authentication. Revoking access in Fiest remains the authoritative way to
remove the grant.
Troubleshooting
- Authentication required: run
claude mcp login fiest. You can also open/mcp, select the connection, and authenticate. - Browser did not open: copy the authorization URL shown by Claude Code and open it in your browser.
- Connection was revoked: authenticate again through
/mcp. - Wrong restaurant: revoke the Fiest authorization and reconnect, selecting the correct restaurant.
See the official Claude Code MCP documentation for client-specific options.
Connect Fiest to Codex
The Codex app, Codex CLI, and Codex IDE extension share MCP configuration when they run on the same Codex host.
1. Copy and run this command
codex mcp add fiest --url https://mcp.fiest.io/mcpYou can also add the server in the Codex app from Settings → MCP servers → Add. Choose Streamable HTTP and copy the address shown above.
2. Approve access in Fiest
Restart Codex if the new server does not appear immediately. Open the MCP server list, select Fiest, and choose Authenticate. Codex opens the Fiest authorization flow in your browser.
You can start the same flow from your terminal:
codex mcp login fiestCodex requests the scopes advertised by the Fiest MCP server. Sign in if needed, choose one restaurant or review an organization connection, then approve the requested access shown by Fiest.
No credentials to configure
Do not add an API token, client secret, or one-time code. Authentication happens on the official Fiest page opened by Codex.
3. Check that it worked
Ask Codex:
Use Fiest to show the restaurant context I authorized.You are connected when Codex calls get_restaurant_context and shows the
restaurant or organization you approved.
Manage the connection
codex mcp list
codex mcp get fiest
codex mcp remove fiestYou can also inspect authentication and available tools from the Codex MCP
server screen or /mcp.
Troubleshooting
- Server needs authentication: open the MCP server screen and authenticate, or rerun the matching login command above.
- Authentication expired: authenticate again. Fiest keeps tokens bound to the exact MCP resource instead of accepting a less secure unbound refresh.
- Server was just added: restart Codex, then inspect
/mcp. - Authorization was revoked in Fiest: authenticate again.
- Wrong restaurant: revoke the grant in Fiest and reconnect with the intended restaurant.
See the official Codex MCP documentation for client-specific configuration.
Connect Fiest to Claude
Add from the Claude directory
- Open Fiest in Claude's connector directory.
- Sign in to Claude if needed and add Fiest.
- Connect your Fiest account, then review and approve access in the Fiest browser authorization flow.
The directory listing uses https://mcp.fiest.io/mcp. The available controls
depend on your Claude plan and organization role. For a team workspace, ask
its owner to make the connector available if needed.
Manual setup
You can also add Fiest as a custom connector using the steps below.
Copy the server address
Use the public Fiest MCP endpoint:
https://mcp.fiest.io/mcpIndividual Pro or Max
- Open Claude and go to Customize → Connectors.
- Select +, then Add custom connector.
- Name the connector
Fiest. - Paste the Fiest server address.
- Add the connector, then select Connect.
- Complete Fiest sign-in, selection, and consent in the browser.
Leave advanced OAuth client credentials empty. Fiest supports automatic OAuth client setup for Claude.
Team or Enterprise
An Owner or Primary Owner first adds the connector:
- Open Organization settings → Connectors.
- Select Add, then Custom → Web.
- Paste the Fiest server address and add the connector.
Each member then opens Customize → Connectors, finds Fiest, and selects Connect to authorize their own Fiest access.
Check that it worked
Enable Fiest for the conversation from the + menu → Connectors. Then ask:
Use Fiest to show the restaurant context I authorized.You are connected when Claude calls get_restaurant_context and shows the
restaurant or organization you approved.
Authorize only on Fiest
Claude should redirect you to the official Fiest authorization page. Never paste a password, one-time code, or token into a Claude conversation.
Troubleshooting
- Add connector is unavailable: your plan or organization role may not permit custom connectors. Ask the workspace owner.
- Fiest is connected but unavailable in chat: enable it for the current conversation from the + menu.
- Access was revoked: select Connect again and repeat Fiest authorization.
See Anthropic's custom connector guide for current plan and role details.
Connect Fiest to ChatGPT
ChatGPT can use Fiest through a custom MCP app. Custom app creation depends on your ChatGPT plan, workspace settings, and role.
Before you begin
Your workspace must allow custom apps and developer mode. Business and Enterprise/Edu administrators control availability and publishing.
If you cannot see Create in Settings → Apps, ask your workspace administrator to enable custom MCP apps or create Fiest for the workspace.
1. Copy the server address
Use the public Fiest MCP endpoint:
https://mcp.fiest.io/mcp2. Create the app
The application may label custom MCP setup as Create app, Create MCP app or Add plugin. These custom connections are separate from a published directory listing.
- Open Settings → Apps → Create. Administrators can also use Workspace settings → Apps → Create.
- Name the app
Fiest. - Paste the Fiest server address as the MCP endpoint.
- Choose OAuth authentication.
- Connect or scan the server. If tools are still loading after authorization, refresh the tool list.
- Complete Fiest sign-in, restaurant or organization selection, and consent when the browser prompt opens.
- Finish creating the app.
Leave OAuth client IDs, client secrets and request headers empty when the client supports automatic registration. Choose stay-connected access in Fiest consent so the client can refresh without another sign-in.
Fiest advertises refresh access through standard OAuth discovery so supported clients can keep the connection active without asking you to sign in for every session.
3. Check that it worked
Open a new chat and select Fiest from the tools or apps menu. Ask:
Use Fiest to show the restaurant context I authorized.You are connected when ChatGPT calls get_restaurant_context and shows the
restaurant or organization you approved.
Do not share credentials in chat
Fiest authentication happens in the browser window opened by ChatGPT. Never paste a password, one-time code, access token, or authorization code into a ChatGPT conversation.
Publish for a workspace
Administrators can review the draft in Workspace settings → Apps → Drafts and publish it to approved users. Review the available tools and action controls before publishing. New or changed write tools should remain disabled until the workspace has reviewed them.
Troubleshooting
- Create is missing: developer mode or custom apps are not enabled for your account or workspace.
- Tool scan asks for authorization: complete the Fiest OAuth flow in the browser, then wait for the scan to finish.
- The app is not available in chat: select it from the tools menu, or ask an administrator to publish or enable it.
- Authorization was revoked: reconnect Fiest from the app's settings.
See the official OpenAI guides for developer mode and MCP apps and apps in ChatGPT.
