OpenAPI · Postman · GraphQL · HTML
Works with any API format
Features
OpenAPI 3.x, Swagger 2.0, Postman collections, GraphQL schemas, and even raw HTML documentation.
Your MCP server is live and callable the moment you upload your spec. Hosted on AWS — no containers, no config, no waiting.
Issue scoped API tokens per tool, per user, per client. Revoke at any time without touching your server.
Secrets are encrypted at rest using Supabase Vault. Plaintext credentials never touch our database.
See exactly which tools are being called, by which token, and how often — per-tool and per-token call counts updated in real time.
Update your spec and BlitzMCP automatically re-parses and redeploys — zero downtime, same URL.
How it works
Drop in an OpenAPI file, paste a URL, or point us at a Postman collection. We handle the parsing — including messy real-world specs.
Inspect the generated tool manifest, set authentication, and choose which operations to expose. Full control, zero boilerplate.
Get a stable MCP endpoint URL. Point Claude, GPT, or any MCP-compatible agent at it and you're done.
