# Remove every source classification rule

`DELETE /api/mcp/projects/{projectId}/sources/rules`

## Request

- Base URL: `https://app.searchable.com`
- URL: `https://app.searchable.com/api/mcp/projects/{projectId}/sources/rules`
- Auth: HTTP bearer

Removes every source classification rule of the project, so each cited source takes its built-in Source Type again. Requires the `source:classify` capability, and your own project role must allow managing the project (otherwise 403 `forbidden`). A pitch project that is not currently active refuses with 409 `INACTIVE_PITCH_PROMPT_MUTATION`. Numbers refresh within a few minutes: the answer carries `status.applying: true`, so poll `GET /projects/{projectId}/sources/rules` until `status.applying` is `false`.

## Other responses

- `401`: Error response. `code` is the machine-readable reason — see the [error reference](/api/errors) for the full catalog and remediation per code.
- `403`: Error response. `code` is the machine-readable reason — see the [error reference](/api/errors) for the full catalog and remediation per code.
- `404`: Error response. `code` is the machine-readable reason — see the [error reference](/api/errors) for the full catalog and remediation per code.
- `409`: Error response. `code` is the machine-readable reason — see the [error reference](/api/errors) for the full catalog and remediation per code.
- `429`: Rate limited. Usually the per-API-key REST limit (600 requests/minute); on Google-backed endpoints it can also relay an upstream Google rate limit. `Retry-After` (seconds) is present when the limit was applied by Searchable's own rate limiter; it may be absent when an upstream provider rate-limits.
