# Cancel a connection request

`POST /server-connections/{requestId}/cancel`

Stops a request and invalidates its handoff link. Cancelling an already-terminal request is a no-op.

## Path parameters

- `requestId` string, required

## Request body

- object

## Response `200`

Request cancelled.

- ServerConnection — The state of one "connect this MCP server" request. Every server-connection route returns this shape, so a caller polls exactly what it created.
  - `connectionRequestId` string, required — Public `scr_…` identifier. Safe to print; it is never sufficient to act on a request.
  - `status` 'discovering' | 'awaiting_project' | 'awaiting_authorization' | 'authorizing' | 'validating' | 'ready' | 'failed' | 'expired' | 'cancelled', required
  - `handoffUrl` string — Where the user finishes in a browser, for both `awaiting_project` and `awaiting_authorization`. Returned ONLY by the create call — the raw token behind it is minted once and never stored. Treat it as a private, single-person capability: never post it to a shared channel.
  - `expiresAt` string, date-time, required
  - `projectId` string
  - `serverId` string
  - `server` object
    - `id` string
    - `name` string
    - `url` string — Redacted: query values are replaced, because a keyed-endpoint URL's query can be the credential.
    - `enabled` boolean
  - `error` object
    - `code` string
    - `message` string
    - `retryable` boolean — Whether retrying THIS request could succeed.
    - `candidates` object[] — Present only on AMBIGUOUS_SERVER: the saved servers the URL matched, so the caller can re-send with a serverId.
      - `id` string
      - `name` string
      - `url` string

## Other responses

- `400` — Malformed body or parameters.
- `401` — Missing, invalid, revoked, or orphaned key (`UNAUTHORIZED`) — or the **target MCP server** needs an OAuth grant (`OAUTH_REQUIRED`), which is a property of the server, not your key.
- `403` — Key is valid but not allowed to do this.
- `404` — Unknown project, server, or resource.
- `409` — The resource is not in a state that accepts this write — a stale `expectedRevision`, a duplicate name, or an environment that cannot currently be launched. The request was well-formed; re-read the resource and retry.
- `429` — Per-key rate limit exceeded (60 requests/minute sustained, bursts up to 10). Honor `Retry-After` and back off with jitter.
- `500` — Something failed on MCPJam's side.
