# Delete an eval suite

`DELETE /projects/{projectId}/eval-suites/{suiteId}`

Deletes the suite and its cases. Past runs are not deleted.

A CI-owned suite (see `EvalSuiteDetail.managedBy`) refuses this with `409`; send its file's `suite.id` as `declaredSuiteId` to delete as the file.

## Path parameters

- `projectId` string, required
- `suiteId` string, required

## Query parameters

- `declaredSuiteId` string

## Headers

- `x-mcpjam-eval-vocabulary` '1' | '2'

## Response `200`

The suite was deleted.

- EvalDeleted
  - `id` string, required
  - `deleted` true, required

## Other responses

- `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.
- `502` — Could not connect to the target MCP server.
