Generator
OpenAPI to MCP
OpenAPI is the cleanest starting point for agent tools because it already describes routes, parameters, request bodies, auth, and response shapes. Astrail turns that contract into a hosted MCP endpoint with reviewable tool metadata and runtime logs.

Guide
When OpenAPI works best
Use OpenAPI when your API already has a stable contract and the agent needs precise actions instead of browser guessing. The generated MCP layer gives the agent names, schemas, and structured errors without asking it to improvise raw HTTP requests.
For small APIs, direct tool exposure can be enough. For large APIs, pair endpoint search with focused tool calls so the agent does not load hundreds of operations into one context window.
Guide
What to review before production
Check destructive methods, private endpoints, auth injection, request size, response size, and rate limits. A generated MCP endpoint should still behave like production infrastructure.
Astrail keeps endpoint maps, diagnostics, and logs visible so teams can audit what the agent was allowed to call and what happened at runtime.
FAQ
Common questions.
Can Astrail discover a spec from Swagger UI?
Yes. Astrail can start from direct OpenAPI files as well as docs pages that expose Swagger UI, Redoc, YAML, or JSON specs.
Should every OpenAPI route become a tool?
No. Large APIs usually work better with search, endpoint inspection, and a smaller active tool surface.
