List MCP endpoints
const url = 'https://example.com/v1/mcp/endpoints?limit=25&transport=stdio&scopeKind=tenant&inherit=true';const options = {method: 'GET', headers: {Authorization: 'Bearer <token>'}};
try { const response = await fetch(url, options); const data = await response.json(); console.log(data);} catch (error) { console.error(error);}curl --request GET \ --url 'https://example.com/v1/mcp/endpoints?limit=25&transport=stdio&scopeKind=tenant&inherit=true' \ --header 'Authorization: Bearer <token>'Cursor-paginated. Optional ?transport= narrows to a single variant (stdio | http-sse | streamable-http). ?scopeKind + ?scopeId + ?inherit narrow to a specific scope; inherit is LOAD-BEARING here (policy/config-scoped binding — controls the upward-hierarchy walk).
Authorizations
Section titled “Authorizations”Parameters
Section titled “Parameters”Query Parameters
Section titled “Query Parameters”1..100. Default 25.
Where the previous page ended: its nextCursor, as it came. A runtime that seals cursors takes one only for the same list, filters and caller, within a day; otherwise 400 bad-input, and the list starts again without it. Absent → first page.
MCP transport variant. stdio — local subprocess (spawn a command). http-sse — the older MCP HTTP+SSE transport (separate POST + SSE endpoints). streamable-http — the Streamable HTTP transport (single endpoint, session id via header).
Filter to endpoints of a single transport variant. Values: stdio | http-sse | streamable-http.
Discriminator for the ?scopeKind + ?scopeId + ?inherit triplet. Tenant carries no id (implicit from session); org/project require scopeId.
Optional scope discriminator. If absent, no scope filter is applied.
Required IF scopeKind is org or project. MUST be absent if scopeKind=tenant (tenant is implicit from the session). Malformed combinations return 400 scope-invalid.
Default true. false = literal-at-this-scope only (admin/audit view). Load-bearing for policy/config-scoped resources (mcp-endpoints); documented no-op for content-scoped resources (agents/flows/tools/…).

Optional distinct SSE endpoint if the server splits them.
Headers sent with every request, as given. Not for a credential: a header named Authorization, Proxy-Authorization or Cookie, or with a -/_-separated part token, secret, password, passwd, apikey, credential, credentials, signature, session, auth, authorization or authentication, or the parts api-key, access-key, private-key, auth-key, subscription-key, functions-key, application-key, app-key, master-key, client-key or partner-key (X-Api-Key, X-Auth-Token), is refused (invalid-mcp-endpoint, reason credential-in-headers). Send it by reference: auth with scheme: header, or secretRef for a bearer. An endpoint registered with one before keeps working, and its value reads back as [redacted].

object
The secret an MCP endpoint authenticates with: a name in the deployment’s secrets store, resolved at the endpoint’s tenant scope by the runtime (the shape webhooks and providers use). As the endpoint’s own secretRef, it is sent as its bearer; inside auth, it is the scheme’s password, client secret or header value. The endpoint keeps only this reference.
object
HTTP Basic: the runtime sends Authorization: Basic base64(<username>:<secret>), with the secret secretRef names (a WordPress Application Password, for one).
object
The user name. Not a secret, and without :.
The secret an MCP endpoint authenticates with: a name in the deployment’s secrets store, resolved at the endpoint’s tenant scope by the runtime (the shape webhooks and providers use). As the endpoint’s own secretRef, it is sent as its bearer; inside auth, it is the scheme’s password, client secret or header value. The endpoint keeps only this reference.
object
OAuth 2 client credentials: the runtime asks tokenUrl for an access token (grant_type=client_credentials) as clientId, with the client secret secretRef names, sends it as the endpoint’s bearer, and asks for a new one before it expires (Drupal’s Simple OAuth, for one). The token is never stored.
object
The token endpoint: https, or http to a loopback host (localhost, 127.0.0.1, [::1]).
The secret an MCP endpoint authenticates with: a name in the deployment’s secrets store, resolved at the endpoint’s tenant scope by the runtime (the shape webhooks and providers use). As the endpoint’s own secretRef, it is sent as its bearer; inside auth, it is the scheme’s password, client secret or header value. The endpoint keeps only this reference.
object
The scopes to ask for, space-separated, sent as-is. Absent: none asked for.
An audience parameter, for identity providers that need one. Absent: none sent.
How the client authenticates to the token endpoint (RFC 6749 §2.3.1): client_secret_basic (an Authorization: Basic header, the default) or client_secret_post (client_id and client_secret in the form).
Headers of the server’s own, each with a secret: an API key in X-Api-Key, a key and a secret in two headers, or Authorization with a prefix other than Bearer (Token …). The runtime resolves each secretRef when it connects, and refuses to follow a redirect with them, as it does for every auth.
object
One header a header auth sends: <name>: <prefix><secret>.
object
An HTTP header name, once per auth (case-insensitive). Not one the MCP transport or HTTP sets itself (Host, Content-Type, Content-Length, Accept, Connection, Mcp-Session-Id, Mcp-Protocol-Version, Last-Event-ID, traceparent, tracestate, …): reason invalid-auth.
The secret an MCP endpoint authenticates with: a name in the deployment’s secrets store, resolved at the endpoint’s tenant scope by the runtime (the shape webhooks and providers use). As the endpoint’s own secretRef, it is sent as its bearer; inside auth, it is the scheme’s password, client secret or header value. The endpoint keeps only this reference.
object
Text sent before the secret, such as Token or ApiKey , without control characters. Absent: none. Not a secret: it reads back as registered.
Optional pass-through to the MCP client serverInfo.instructions.
Optional caller-defined metadata bag.
object
Send the W3C traceparent of the run calling a tool to this endpoint, as a request header, so the server’s logs can be matched to the run. Ids only, never content. Default false. HTTP transports only: true on a stdio endpoint is refused (invalid-mcp-endpoint, reason invalid-send-traceparent). An older runtime ignores it and sends none.
Where each secret it names is read, by name: recorded by the server when it was registered, never sent by a caller. null: none usable (the registrant administers no scope the secret could be read at), until an admin records it again: a tool by publishing a new version, an MCP endpoint by unregistering it and registering it again. Absent on items registered before it was recorded, or on a runtime without a secrets store.
