Turn **any** OpenAPI/Swagger API into [Model Context Protocol](https://modelcontextprotocol.io)
tools. Point the bridge at a spec (URL or local file) and every endpoint becomes
an MCP tool that an AI assistant — Claude Desktop, or any MCP client — can call
directly. The bridge constructs the real HTTP request, sends it, and returns the
response to the model.

- 🔧 **One tool per endpoint** — names from `operationId`, JSON Schema inputs
  built from parameters and request bodies.
- 📥 **OpenAPI 3.x and Swagger 2.0** — both normalised to the same model.
- 🔌 **stdio transport** built on the official [`mcp`](https://pypi.org/project/mcp/) SDK.
- 🔒 **No secrets in code** — every credential comes from an environment variable.
- ✅ **Typed, tested, and linted.**

## Installation

```bash
pip install openapi-mcp-bridge
```

Or install it as an isolated CLI tool:

```bash
pipx install openapi-mcp-bridge
```

It requires Python 3.10+.

## Quickstart

List the tools generated from the public Swagger Petstore spec (this does **not**
start a server — handy for inspecting what will be exposed):

```bash
openapi-mcp-bridge --spec https://petstore3.swagger.io/api/v3/openapi.json --list-tools
```

Run it as an MCP server over stdio:

```bash
openapi-mcp-bridge --spec https://petstore3.swagger.io/api/v3/openapi.json
```

You can also invoke it as a module:

```bash
python -m openapi_mcp_bridge --spec ./openapi.yaml
```

## Use with Claude Desktop

Add an entry to your `claude_desktop_config.json`:
