POST/api/v1/mcp-eval

Run MCP eval

Runs an MCP tool-use evaluation synchronously and returns the result with 201. Body: { projectId (required), tools (non-empty array of MCP tool declarations, required), timeout? (ms, default 30000), model? (default llama-3.3-70b-versatile), provider? (inferred from the model otherwise) }. The judge model is called with the PLATFORM provider key from the environment — 400 MISSING_PROVIDER_KEY if none is set for that provider. Returns overall score, tool-selection / tool-parameter / multi-step accuracy, compliance checks, security findings, performance benchmarks and the report, and persists the same into mcp_eval_results. Requires evals:create; membership of the project's org is verified first; rate-limited to 5/min.
