Implementation tutorials

Build production MCP endpoints from real API contracts.

Practical, copyable guides for generating MCP from OpenAPI, adding auth, testing endpoint behavior, exporting SDKs, and adapting common API shapes.

Generate an MCP server from OpenAPI

A practical tutorial for turning an OpenAPI or Swagger spec into a hosted MCP endpoint agents can inspect and call.

What you will ship

You will have a hosted MCP endpoint with initialize, tools/list, tools/call, search_docs, and execute ready for local testing.

Configure API keys, bearer tokens, and OAuth-style credentials for generated MCP tools without leaking secrets into tool metadata.

A preflight checklist for generated MCP endpoints: initialize, tools/list, schema validation, auth failure, safe execution, and logging.

Export a generated SDK bundle, verify its docs and tests, and prepare package publishing without disconnecting it from the hosted MCP endpoint.

Use the public Petstore OpenAPI spec to create a safe demo MCP server for search_docs, execute, and read-only endpoint testing.

Turn repository, issue, pull request, and workflow endpoints into agent tools with safe read defaults and reviewed write actions.

Create payment and billing MCP tools with test-mode credentials, strict auth boundaries, idempotency, and safe production checks.

Expose internal REST APIs to agents with narrow endpoint selection, network boundaries, service credentials, and audit-friendly runtime logs.

Fix common OpenAPI to MCP generation issues: missing specs, invalid schemas, auth confusion, oversized tool lists, and broken execute calls.
