About MCP-Bridge

MCP-Bridge is a free browser-based tool that converts any OpenAPI v3 specification into a ready-to-use MCP server configuration. It indexes 412 MCP servers, supports 1015+ popular APIs, and provides 28 framework-specific .cursorrules files — all with zero backend and zero signup.

Why we built this

The MCP ecosystem is growing rapidly — but most API providers haven't published MCP configs yet. MCP-Bridge automates the conversion process so developers don't have to manually translate OpenAPI specs to MCP format. We also track 412 native MCP servers across 11 categories with quality scores, health checks, and one-click install snippets for Claude Desktop, Cursor, and VS Code.

Privacy-first by design

The converter runs entirely in your browser. Your OpenAPI spec is parsed locally — nothing is sent to any server. No accounts, no tracking, no data leakage.

Our mission

Accelerate MCP adoption by making it trivially easy to connect any API to any MCP-compatible client — Claude Desktop, Cursor, Cline, or any tool in the growing MCP ecosystem.
