mcp-bridge turns OpenAPI specs into MCP servers

mcp-bridge is an open-source CLI and library that generates MCP servers from REST API specs, supporting OpenAPI 3.x and Swagger 2.0, Zod schema generation, auth, endpoint filtering, watch mode, and TypeScript or JavaScript output. Point it at a spec or a live API and it produces a runnable MCP server for tools like Claude, Cursor, and Windsurf without hand-writing boilerplate.

// ANALYSIS

Hot take: this is genuinely useful infrastructure for teams that already have decent API specs, because it collapses the “build an MCP wrapper” problem into a generation step.

–Strong fit for internal APIs, rapid prototyping, and teams that want to expose an existing REST surface to agents quickly.
–The real quality gate is the source spec; messy OpenAPI docs, inconsistent auth, or poor endpoint design will still produce a brittle MCP server.
–The endpoint filtering and watch mode matter more than the headline: they make the generated server practical instead of just demoware.
–Open source plus programmatic usage makes it easy to slot into existing workflows, which is a better signal than a one-off hosted wrapper.
