HTTP reference: the REST API for physical tasks

The REST API that sits under the 4bl1ty MCP tools. It is the API — not the MCP server — that enforces every rule that matters: roles, identity verification, status transitions, amounts. So it is also the API that produces the errors your tools hand back to you.

The server is a translator#

Most MCP tools translate to the route shown below. The server also keeps the authentication token in memory, tries compatibility route fallbacks, rejects unsafe digital missions and validates proof URLs. The auth_clear tool is local and makes no HTTP call.

The API is not public either: it listens on http://localhost:3001 by default (API_PORT). No domain, no API version in the path, no rate limit.

Tool to route#

The complete table, in the order the server declares the tools. {id} is substituted with the tool’s identifier parameter.

ToolMethodPath
auth_loginPOST/auth/login
auth_statusGET/auth/me (only when authenticated)
auth_clearLOCALprocess memory
missions_listGET/prestations (fallback: /missions)
missions_getGET/prestations/{id} (fallback: /missions/{id})
missions_createPOST/prestations (fallback: /missions)
claim_missionPOST/bookings (fallback: /missions/{id}/claim)
claims_listGET/bookings (fallback: /claims)
claims_getGET/bookings/{id} (fallback: /claims/{id})
claims_update_statusPUT/bookings/{id}/status (fallback: /claims/{id}/status)
claims_submit_proofPOST/bookings/{id}/proof (fallback: /claims/{id}/proof)
kyc_statusGET/auth/me

Authentication#

A JWT carried by the Authorization header. It is issued by POST /auth/register and POST /auth/login, and signed with the API’s JWT_SECRET: change that secret and every token in circulation becomes invalid.

Headers of any authenticated request
Authorization: Bearer <jwt>
Content-Type: application/json

The identity verification wall#

Three routes go through an extra check that reads the account’s kycStatus and demands the value verified: POST /prestations, POST /bookings and POST /bookings/{id}/pay. An admin account is exempt.

403 — exact body
{
  "error": "KYC non validé",
  "kycStatus": "pending",
  "message": "Vous devez compléter la vérification d'identité avant de pouvoir effectuer cette action."
}

The two routes that move an account from pending to verified — POST /auth/kyc/start remains outside MCP.kyc_status can read useful state from the current profile, but cannot start or resume onboarding.

Roles#

The role is chosen at registration and no MCP tool changes it. It decides everything else:

  • customer — the only role that can publish a listing, accept an application, pay for it and leave a review.
  • provider — the only role that can apply to a listing and set up Stripe Connect.
  • admin — exempt from both the role check and identity verification.

Application statuses#

An application is created as pending. Any transition not listed below is rejected with a 400, and a transition asked for by the wrong role with a 403. The paid status is not reachable through this route: it is set by the payment.

FromToBy
pendingconfirmed, cancelledcustomer or provider
confirmedin_progress, cancelledcustomer or provider
paidin_progress, cancelled, disputedcustomer or provider
in_progresscompleted, disputedcustomer or provider
completeddisputedcustomer only

Moving an application to completed timestamps the end of the task, but does not release the funds: that is POST /bookings/{id}/validate, and that route has no tool.

Amounts and escrow#

  • Everything is in cents. price, totalAmount, platformFee and providerAmount are integer counts of cents. The tools’ response messages reformat them in euros for reading; never parse those strings back.
  • The fee is frozen at application time. The moment a provider applies, the API computes platformFee from STRIPE_PLATFORM_FEE_PERCENT (10 % by default) and derives providerAmount from it. Editing the listing’s budget afterwards does not recompute applications already filed.
  • The payment goes to the platform, not to the provider. That is what escrow means here: the funds are held, then paid out on validation.
  • Payment has two possible responses. If the provider has no Stripe Connect account, the API answers demoMode: true and simulates the escrow — no real money moves. Otherwise it returns a Stripe Checkout URL.

Errors#

Every error carries an error field written in French. Validation errors add details, which is the raw output of the validator — in English, and the only place where the API does not speak French.

400 — validation body
{
  "error": "Données invalides",
  "details": [
    {
      "code": "too_small",
      "minimum": 10,
      "path": ["description"],
      "message": "String must contain at least 10 character(s)"
    }
  ]
}
CodeWhen
400Invalid body (Zod schema), or a rejected status transition.
401Authorization header missing, malformed, or token expired.
403Insufficient role, different owner, or identity verification not passed.
404Resource not found — or the route does not exist.
409State conflict: listing closed to applications, review already filed, deletion impossible.
500Uncaught error. The body then says nothing usable.

On the MCP side, all of this arrives in the same shape: isError: true and a JSON { "success": false, "error": "…" }. The validation details field is lost in translation — only the main message survives.

Routes with no tool#

The API serves more than the MCP server exposes. These routes exist and work; they are simply only reachable over direct HTTP.

  • GET /healthLiveness probe. No authentication.
  • PUT /auth/meEdit your own profile.
  • POST /auth/kyc/startStart identity verification.
  • GET /auth/kyc/statusRead the state of the verification.
  • GET /prestations/meta/categoriesCategories the API knows about.
  • POST /bookings/{id}/validateDouble validation, then escrow release.
  • POST /bookings/{id}/disputeOpen a dispute.
  • GET /bookings/disputes/listOpen disputes.
  • PUT /bookings/disputes/{id}/resolveArbitrate a dispute.
  • POST /stripe/webhookSigned Stripe callback. Raw body, not JSON.
  • GET /stripe/connect/refreshResume a Stripe onboarding flow.
  • POST /chat · GET /chat/configMessaging.

The two blocking gaps

  • Funding and payment — `missions_create` creates a draft only. MCP cannot fund it, open it, notify humans, release funds, refund a payment or arbitrate a dispute. Payment remains an external human/platform flow.
  • KYC onboarding — `kyc_status` can report verification state, but no MCP tool starts or resumes Stripe onboarding. A provider must complete that flow outside MCP before `claim_mission` can succeed.
