## The problem

Two tool-calling formats now dominate agent development:

- **MCP** (Model Context Protocol) — the format most Claude-first tools, IDEs, and local dev tooling speak.
- **OpenAI function-calling** — the `tools=[{"type": "function", ...}]` JSON-Schema format used by the OpenAI API and every SDK/framework that mirrors it (LangChain, most self-rolled agent loops, etc.).

If your agent only speaks OpenAI function-calling, the fast-growing MCP server ecosystem (filesystem tools, database connectors, SaaS integrations, dev tools) is invisible to it — unless someone hand-writes a per-server adapter, or adopts a full proxy that speaks MCP on one side and OpenAI-compatible chat completions on the other.

**`mcp-openai-bridge` is a narrower shim.** Point it at any MCP server, get back a local HTTP endpoint that speaks pure OpenAI function-calling — just tool listing and tool execution, nothing else.
