Upload an OpenAPI, Postman, or GraphQL spec and BlitzMCP instantly generates and hosts a production-grade MCP server — no code, no infra, no hassle.
No credit card required · Deploy in under 60 seconds
Step 1 — Upload your spec
Drop your spec here
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 on a globally-distributed edge network the moment you upload your spec.
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 — with per-tool call counts, error rates, and latency charts.
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.
Stop writing glue code. BlitzMCP turns your existing API into an MCP server that any AI agent can use — in seconds.
