Accounts & authentication
Start linking an account at a provider
POST /api/v1/auth/providers/{provider}/link
Starts linking an account at a sign-in provider. From a browser that a person signed in to with an email link, a passkey, or a provider, within the last 10 minutes; a token cannot, since a linked account outlives any token. An older session answers 403 with next.action sign_in: sign in again, then start again. Returns the provider's authorization page to send the browser to.
Parameters
Originheader · required · stringThis server's origin. Required with the browser session cookie.
providerpath · required · stringThe provider, such as
google.Idempotency-Keyheader · optional · stringMakes a retry safe: a request with the same key and the same method, path, and body as an earlier one gets the earlier response instead of doing the work again. 1 to 255 visible ASCII characters; use a new key for each new request, such as a UUID. Keys are kept per caller for a day, and ignored for requests without credentials.

RateLimit and RateLimit-Policy describe the request rate. Follow Retry-After when a response asks you to wait.
Problem responses
Errors use application/problem+json. Act on the stable code, and follow next when present. See the problem format.
check_key_scope403A check-only key may call the test check, read its own usage and acceptance rule, contact support, and withdraw data sharing.
Use a person's sign-in for account management. More agent power needs the owner's passkey; this key cannot widen itself.
feature_off403The namespace plan does not include this feature.
Retrying on the same plan will not help. GET /api/v1/namespaces/{namespace}/plan, and the namespace's Plan page in Settings, show what its plan includes.
unauthenticated401The request carried no credentials.
Use this operation's sign-in method. Bearer credentials use
Authorization: Bearer <token>; browser credentials use the session cookie.invalid_token401The token is unknown, expired, or revoked, its agent was revoked, or an OAuth token was used outside its MCP resource.
Stop using it. Sign in again, or ask the owner to create a replacement agent key.
forbidden403The caller may not do this: only people may, only owners may, or the agent was not given this repository or write access.
Stop. Retrying will not help. Ask the owner for the access, or leave the step to a person.
not_found404It does not exist, or the caller cannot read it: a repository the caller cannot read is reported as not found.
Check the name or ID, and that the token has the repository.
invalid_request400The request is malformed or breaks a rule, such as a title that is too long, or a body that is not the expected JSON.
Fix the request as
detailsays. The same request fails the same way.quota_exceeded429With 429, the caller used its requests for the minute. With 422, a count limit was reached.
With 429, wait
Retry-Afterseconds and retry. With 422, remove one first.idempotency_key_reused409 / 422The idempotency key was already used for a different request.
Use a new key for each new request, and the same key only for a retry of the same request.
idempotency_key_in_use409The first request with this key is still running, including a queued model question, or it succeeded with a secret, such as a new token, which is never replayed.
When
Retry-Afteris set, retry then with the same key. Otherwise the first request succeeded: do not repeat it.internal500The server failed, and logged why.
Retry after
Retry-Afterseconds. A write is safe to retry with the same idempotency key.unavailable502 / 503With 502, a service the server needs did not answer, such as a sign-in provider. With 503, the server is busy, such as when a workspace is locked or host lookups are full, or a write with an idempotency key runs long: that write goes on, and its answer is kept for the key.
With 502, retry later, or sign in another way. With 503, retry after
Retry-Afterseconds, using the same idempotency key for a write; a long-running write can then replay its answer.
