The platform selects the cases — see the rerun preview. The new run records `rerunOfRunId` and `rerunScope`, and because its pass rate is biased by that selection it is never used as the suite's latest run, a trend point, or a comparison/gate baseline. Returns `409` with `details.reason` `RERUN_NOTHING_TO_RERUN` when nothing qualifies, or `RERUN_SOURCE_NOT_TERMINAL` while the run is still in flight. Honors the `Idempotency-Key` header. ## OpenAPI ````yaml /reference/openapi.json post /projects/{projectId}/eval-runs/{runId}/rerun openapi: 3.1.0 info: title: MCPJam API version: 1.0.0-preview description: >- Programmatic access to MCP servers saved in your MCPJam projects — live diagnostics (validate, inspect, export) and operations: call tools, render prompts, run eval suites asynchronously and poll their results, and import OAuth tokens. **The API is in preview**: the surface may change while we finish the design. Error `code` values are stable; error `message` strings are not. Write clients that ignore unknown response fields. contact: name: MCPJam url: https://github.com/MCPJam/inspector/issues servers: - url: https://app.mcpjam.com/api/v1 description: Hosted MCPJam security: - bearerAuth: [] tags: - name: Agent browsers description: >- Isolated cloud browser sessions for coding agents. Requires authenticated project membership and a configured desktop runtime. - name: Clients description: >- Clients — the named, reusable configurations that define how MCPJam connects to and talks to your MCP servers. The original `/hosts` paths remain as deprecated, ID-only compatibility aliases with their original DTOs and their original (tokenless) write contracts; every alias response carries `Deprecation: true`. New integrations should use `/clients`. - name: Environments description: >- Project environments: named, live-editable execution bundles (one host, an optional standalone server group, optionally pinned skills and plugin versions) that eval suites and goals run against. Distinct from Sandbox images, which are Computer base images. Reads require project membership; every write requires project admin. - name: Plugins description: >- Agent Plugins imported into a project — read-only inventory and version detail. - name: Skills description: >- Cloud Skills: authored SKILL.md files stored in a project. Read-only here. Environments pin skills by id (`skillSelection.skillIds`) and eval runs pin them with `--compose-skill`, so this surface exists to give an unattended caller those ids; authoring is an app flow behind a beta gate. - name: Sandbox images description: >- Custom Computer images: a digest-pinned Dockerfile built into an immutable image your project's computers boot from. - name: Server diagnostics description: Connect-level health checks against a saved MCP server. - name: Primitives description: 'The server''s MCP primitives: tools, prompts, and resources.' - name: Export description: Full-server snapshots for diffing and CI. - name: Execution description: 'Run the server''s primitives: call tools, render prompts.' - name: Eval runs description: >- Asynchronous eval suite runs: create with 202, poll status, iterations, and traces. - name: Conformance runs description: >- Ingest MCP spec-conformance results from the SDK/CLI into project-owned history. Distinct from Eval runs (authored LLM cases) and from directory readiness. - name: Server connections description: >- Connect an MCP server URL to a project, authorizing in a browser when the server requires it. - name: OAuth description: 'Bring-your-own OAuth: import externally obtained tokens for a server.' - name: Studies description: >- Publish a project environment as a **study** for people outside the project to talk to, read what they did, and control who can reach it. Several of these NARROW access and take effect immediately. The pre-rename paths — `/projects/{projectId}/scenarios`, `/projects/{projectId}/scenarios/{scenarioId}`, `/projects/{projectId}/environments/{environmentId}/scenario` and `/projects/{projectId}/user-testing/scenarios/{scenarioId}/…` — keep working and are deliberately not documented here. They return their original bodies, which spell the owning id `scenarioId` and whose detail read carries no execution settings, and every response answers with `Deprecation: true` and a `Link` header naming its successor. They are removed at general availability; a new integration should use the paths on this page. - name: Catalog description: >- Discover the resources the other routes operate on: your account, projects, servers, eval suites, and chat sessions. - name: Tunnels description: >- Relay tunnels that expose local MCP servers through a public URL, registered as first-class project servers (the `mcpjam cloud tunnel` CLI flow). - name: Agent description: >- Headless agent turns over the public API: send a message history, the server runs one assistant turn with project-scoped workspace tools (eval reads + suite creation) on a pinned hosted model, and returns the reply plus created-resource references. - name: Swarms description: >- Personas, journeys and swarm containers — the authoring half of Swarms — plus the model-backed generation that drafts them. - name: Swarm runs description: >- Launching journeys and reading what they produced. Launching SPENDS — see the per-operation notes. - name: Swarm insights description: >- What a swarm run revealed. The scorecard and findings are deterministic and free; requesting wave insights runs models and draws on your shared daily ledger. - name: Directory readiness description: >- Grade a saved server against a publisher's listing requirements: Anthropic's connector directory or OpenAI's plugin directory. Reported as lane status and coverage, never as a numeric score, and excluded from `pooledConformanceScore`. Deterministic grading is free; model-backed experience observations are an explicit opt-in whose model cost is on MCPJam — no credits are consumed — and they can never decide a verdict. - name: Registry description: >- Search the scraped MCP directories (Claude, ChatGPT, and any future source), list curated/org registry cards, and install them into a project. Install writes a `servers` row and provenance — it does not open a live session. There is no catalog-uninstall route: delete the project server instead. Directory reads require a bearer (including minted guest tokens) but do not materialize a user. Card/connection reads and all writes are authed-non-guest. - name: Feedback description: >- Feedback about MCPJam itself (bugs, missing capabilities, confusing behavior), sent to the MCPJam team and kept for 180 days. The `send_feedback` MCP tool calls the same endpoint. paths: /projects/{projectId}/eval-runs/{runId}/rerun: post: tags: - Eval runs summary: Rerun a run's failed cases description: >- Replay a finished run's frozen snapshot narrowed to the cases that did not pass: every case with a trial that is not completed and passed (cancelled and skipped trials do not count).
