# List hosted MCP providers

GET https://api.jelliu.co/api/mcp-servers/providers

Returns the catalogue of hosted MCP providers a workspace can connect with a single token
(currently Make, Zapier and Alegra, in that order): their endpoint, recognised hostnames,
transport, default approval mode, auth scheme, where the token is minted and the description
the agent receives. Use it to build a "connect provider" screen, then call
`POST /api/mcp-servers` with `provider` and `secretToken`.

The content is static and identical for every workspace; it changes only with a Jelliu
release. Nothing in it is secret.

**Idempotency.** Read-only and safe to retry.

**Access**
- **Required scope:** `read` (or `write`). Any workspace role.
- **Rate limit:** General API — 120 (Starter), 200 (Growth), 300 (Business) or 600 (Enterprise) requests/min per workspace. See [Rate limits](/rate-limits).
- **Plan:** Available on every plan.


Reference: https://developer.jelliu.co/api-reference/mcp-servers/get-mcp-servers-providers

## Authentication

- `Authorization` header (bearer token, required) — Workspace API key: `jl_` followed by 64 lowercase hex characters, created by the workspace owner in the dashboard (**Settings → API Keys**) and sent as `Authorization: Bearer jl_...`. The plaintext is shown once, at creation; Jelliu stores only a SHA-256 hash. A workspace can hold up to 25 active keys. | Scope | GET / HEAD | POST / PUT / PATCH / DELETE | Admin-only routes | | --- | --- | --- | --- | | `read` | Yes | No | No | | `write` | Yes | Yes | No | | `full` | Yes | Yes | Yes | Operations restricted to admins or owners reject keys without the `full` scope with `403`, and say so in their description. No key, whatever its scope, can mint or revoke API keys or rotate a webhook secret — that requires a signed-in owner session. A revoked key stops authenticating within about 10 seconds. See [Authentication](/authentication).

## Response

### 200

The provider catalogue.

- `data` (list of object, required)
  - `id` (enum, optional) — Provider identifier to send as `provider` on create — `zapier`, `alegra` or `make`.
    - Allowed values: `zapier`, `alegra`, `make`
  - `name` (string, optional) — Display name; also the default server name.
  - `serverUrl` (string, optional) — The fixed endpoint, or only an example when `requiresExplicitUrl` is true.
  - `hostnames` (list of string, optional) — Hostnames that identify a server URL as belonging to this provider.
  - `transport` (enum, optional) — The only transport the provider accepts (currently `STREAMABLE_HTTP` for all).
    - Allowed values: `SSE`, `STREAMABLE_HTTP`
  - `approvalMode` (enum, optional) — Approval mode applied when the create request does not send one.
    - Allowed values: `always_ask`, `fine_grained`, `no_approval`
  - `tokenQueryParam` (string, optional) — Query parameter the provider also accepts its token on; lifted into the secret on save. Absent when not applicable.
  - `tokenPathPattern` (object, optional) — Present when the provider also accepts its token inside the URL path (Make); the token is lifted into the secret on save. Serializes as an empty object.
  - `requiresExplicitUrl` (boolean, optional) — The endpoint differs per account or region, so `serverUrl` must be sent on create. Absent when false.
  - `authScheme` (enum, optional) — How the credential is sent: `bearer` (default when absent) or `basic` (send the secret as `usuario:token`).
    - Allowed values: `bearer`, `basic`
  - `defaultHeaders` (map from string to string, optional) — Headers every server of this provider carries unless overridden in `customHeaders`.
  - `configUrl` (string, optional) — Where the token is minted.
  - `docsUrl` (string, optional) — The provider's MCP documentation.
  - `description` (string, optional) — The agent-facing description sent to the voice engine by default.

## Errors

### 401 Unauthorized Error

No usable credential. Either the `Authorization` header is missing or is not a well-formed `Bearer jl_…` key, or the key is unknown, revoked or expired. Do not retry with the same key. See [Authentication](/authentication#401-unauthorized).

- `error` (object, required) — The error object. Always has `code` and `message`.
  - `code` (string, required) — Stable machine-readable error code (for example `VALIDATION_FAILED`, `UNAUTHORIZED`, `FORBIDDEN`, `NOT_FOUND`, `BILLING_ERROR`, `COMPLIANCE_BLOCKED`, `RATE_LIMIT_EXCEEDED`, `INTERNAL_ERROR`). Switch on this, not on `message`. See [Errors](/errors).
  - `message` (string, required) — Human-readable explanation. English or Spanish depending on the route; may change without notice.
  - `details` (object or list of object, optional) — Present on `VALIDATION_FAILED` only. Its shape depends on how the route validates: * a field map, either Zod's `flatten()` output (`{ "formErrors": [], "fieldErrors": { "name": ["..."] } }`) or just its `fieldErrors` part (`{ "name": ["..."] }`); * an issue list, where each issue has at least `path`, `message` and `code`. `path` is a dot-separated string on routes that let the schema throw, and an array of keys on routes that forward Zod's raw issues (those also carry Zod's extra issue fields).
    - Field map
      - `formErrors` (list of string, optional)
      - `fieldErrors` (map from string to list of string, optional)
  - `metadata` (map from string to any, optional) — Structured detail exposed for a small allowlist of codes only — for example `BILLING_ERROR` carries `limit`, `current` and `tier` (resource caps) or `tier` and `feature` (feature gates).

### 403 Forbidden Error

The API key has neither `read` nor `write`, or the workspace is suspended.

- `error` (object, required) — The error object. Always has `code` and `message`.
  - `code` (string, required) — Stable machine-readable error code (for example `VALIDATION_FAILED`, `UNAUTHORIZED`, `FORBIDDEN`, `NOT_FOUND`, `BILLING_ERROR`, `COMPLIANCE_BLOCKED`, `RATE_LIMIT_EXCEEDED`, `INTERNAL_ERROR`). Switch on this, not on `message`. See [Errors](/errors).
  - `message` (string, required) — Human-readable explanation. English or Spanish depending on the route; may change without notice.
  - `details` (object or list of object, optional) — Present on `VALIDATION_FAILED` only. Its shape depends on how the route validates: * a field map, either Zod's `flatten()` output (`{ "formErrors": [], "fieldErrors": { "name": ["..."] } }`) or just its `fieldErrors` part (`{ "name": ["..."] }`); * an issue list, where each issue has at least `path`, `message` and `code`. `path` is a dot-separated string on routes that let the schema throw, and an array of keys on routes that forward Zod's raw issues (those also carry Zod's extra issue fields).
    - Field map
      - `formErrors` (list of string, optional)
      - `fieldErrors` (map from string to list of string, optional)
  - `metadata` (map from string to any, optional) — Structured detail exposed for a small allowlist of codes only — for example `BILLING_ERROR` carries `limit`, `current` and `tier` (resource caps) or `tier` and `feature` (feature gates).

### 429 Too Many Requests Error

General API rate limit exceeded.

- `error` (object, required) — The error object. Always has `code` and `message`.
  - `code` (string, required) — Stable machine-readable error code (for example `VALIDATION_FAILED`, `UNAUTHORIZED`, `FORBIDDEN`, `NOT_FOUND`, `BILLING_ERROR`, `COMPLIANCE_BLOCKED`, `RATE_LIMIT_EXCEEDED`, `INTERNAL_ERROR`). Switch on this, not on `message`. See [Errors](/errors).
