drop your openapi.yaml — get a working MCP server in 3 seconds
npx -y github:Isco0819/spec-mcpEver run into this?
like openapi-generator (20k+ GitHub stars), which proves massive demand for spec-to-code generation, but nothing generates an MCP server. every dev team already has an openapi.yaml. every AI agent needs MCP tools. the gap between them is hours of hand-written boilerplate per endpoint.
The fix
spec-mcp ./openapi.yaml parses your spec and emits a fully-wired stdio MCP server with every operation mapped to a typed tool, plus a ready-to-paste claude_desktop_config.json snippet — no manual tool definitions ever.
What it does
- parses openapi 3.x json/yaml and generates MCP tool definitions from operationId, parameters, and requestBody schemas
- auto-wires auth (Bearer / API-key) through env vars — zero secrets hardcoded
- prints a claude_desktop_config.json snippet you can paste and run in 10 seconds
