# Persist advisory case-run evaluations

`POST /projects/{projectId}/eval-ingest/runs/evaluations`

Persist advisory case-run evaluations. Uses the SDK reporting transport and the same tenant/project authorization as eval ingestion. Unsupported capabilities remain absent.

## Path parameters

- `projectId` string, required

## Headers

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

## Request body

- object
  - `runId` string, required
  - `externalRunId` string, required
  - `evaluations` object[], required

## Response `200`

The backend's response, passed through.

- object
  - `ok` boolean, required
  - `runId` string, required
  - `persistedCases` integer, required

## 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.
- `502` — Could not connect to the target MCP server.
- `504` — The target MCP server connected but didn't respond in time.
