# Get one eval case

`GET /projects/{projectId}/eval-suites/{suiteId}/cases/{caseId}`

A case that belongs to this suite and project. A case in another suite is a 404, not a 403.

## Path parameters

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

## Response `200`

The case.

- EvalCase — A persisted eval case, in the public steps-first shape. Note this is NOT `EvalTestCase`, which is the INLINE authoring shape accepted by suite creation.
  - `id` string, required
  - `title` string, required
  - `steps` EvalTestStep[], required — Ordered test steps. A `prompt` step is a model turn; a single model-free `toolCall` step is a render-check; `assert` steps hold the expectations.
    - `id` string, required
    - `kind` 'prompt' | 'toolCall' | 'interact' | 'assert', required
    - `prompt` string — User message (`kind: prompt`).
    - `serverName` string — Server that owns the tool (`kind: toolCall`).
    - `toolName` string — Tool name (`kind: toolCall` / `interact`).
    - `arguments` object — Tool-call arguments (`kind: toolCall`).
    - `action` object — Widget action (`kind: interact`).
    - `assertion` object — Predicate or widget assertion (`kind: assert`).
  - `expectedOutput` string
  - `iterations` integer, required
  - `isNegative` boolean, required — When true, the case passes if NO tools are called.
  - `scenario` string
  - `models` object[], required
    - `model` string, required
    - `provider` string
  - `matchOptions` object, nullable
  - `checks` object, nullable
    - `mode` 'inherit' | 'replace' | 'extend'
    - `list` object[]
  - `createdAt` number, nullable
  - `updatedAt` number, nullable

## 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.
- `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.
