## Bridge the gap between AI agents and external APIs

The OpenAPI to Model Context Protocol (MCP) proxy server bridges the gap between AI agents and external APIs by **dynamically translating** OpenAPI specifications into standardized **MCP tools**, **resources**, and **prompts**. This simplifies integration by eliminating the need for custom API wrappers.

Built with **FastMCP** following official MCP patterns and best practices, the server provides:
- ✅ **Official FastMCP Integration** - Uses the latest FastMCP framework for optimal performance
- ✅ **Proper MCP Transport** - Supports stdio, SSE, and streamable HTTP transports
- ✅ **Modular Architecture** - Clean separation of concerns with dependency injection
- ✅ **Production Ready** - Robust error handling, comprehensive logging, and type safety

  "mcpServers": {
    "weather": {
      "command": "/full/path/to/OpenAPI-MCP/venv/bin/python",
      "args": ["/full/path/to/OpenAPI-MCP/src/fastmcp_server.py"],
      "env": {
        "SERVER_NAME": "weather",
        "OPENAPI_URL": "https://api.met.no/weatherapi/locationforecast/2.0/swagger"
      },
      "transport": "stdio"
    }
  }
}
```

> **Note:** Replace `/full/path/to/OpenAPI-MCP` with your actual installation path.

#### With Local Spec and Custom Headers
```json
{
  "mcpServers": {
    "local_api": {
      "command": "/full/path/to/OpenAPI-MCP/venv/bin/python",
      "args": ["/full/path/to/OpenAPI-MCP/src/fastmcp_server.py"],
      "env": {
        "SERVER_NAME": "local_api",
        "OPENAPI_URL": "./specs/my-api.yaml",
        "MCP_AUTH_HEADERS": "{\"X-API-Key\": \"your-key-here\"}"
      },
      "transport": "stdio"
    }
  }
}
```

#### With Username/Password Authentication
```json
{
  "mcpServers": {
    "secure_api": {
      "command": "full_path_to_openapi_mcp/venv/bin/python",
      "args": ["full_path_to_openapi_mcp/src/server.py"],
      "env": {
        "SERVER_NAME": "secure_api",
        "OPENAPI_URL": "https://api.example.com/openapi.json",
        "API_USERNAME": "your_username",
        "API_PASSWORD": "your_password"
      },
      "transport": "stdio"
    }
  }
}
```

  "mcpServers": {
    "oauth_api": {
      "command": "full_path_to_openapi_mcp/venv/bin/python",
      "args": ["full_path_to_openapi_mcp/src/server.py"],
      "env": {
        "SERVER_NAME": "oauth_api",
        "OPENAPI_URL": "https://api.example.com/openapi.json",
        "OAUTH_CLIENT_ID": "your_client_id",
        "OAUTH_CLIENT_SECRET": "your_client_secret",
        "OAUTH_TOKEN_URL": "https://api.example.com/oauth/token"
      },
      "transport": "stdio"
    }
  }
}
```

#### Multiple API Servers with MCP HTTP Transport

Configure multiple OpenAPI services to run simultaneously:

```json
{
  "mcpServers": {
    "weather": {
      "command": "npx",
      "args": [
        "mcp-remote", 
        "http://127.0.0.1:8001/sse"
      ]
    },
    "petstore": {
      "command": "npx", 
      "args": [
        "mcp-remote",
        "http://127.0.0.1:8002/sse" 
      ]
    }
  }
}
```

This configuration gives Claude access to both weather data AND petstore API tools simultaneously, with clear tool naming like `weather_get__compact` and `petstore_addPet`.

#### Single API Server with MCP HTTP Transport

For a single API service:

**Standard SSE Configuration:**
```json
{
  "mcpServers": {
    "openapi_service": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "http://127.0.0.1:8001/sse"
      ]
    }
  }
}
```

**Streamable HTTP Configuration:**
```json
{
  "mcpServers": {
    "openapi_service": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "http://127.0.0.1:8001/mcp"
      ]
    }
  }
}
```

**With Debugging (for development):**
```json
{
  "mcpServers": {
    "openapi_service": {
      "command": "npx",
      "args": [
        "mcp-remote", 
        "http://127.0.0.1:8001/sse",
        "--debug"
      ]
    }
  }
}
```

**With Custom Transport Strategy:**
```json
{
  "mcpServers": {
    "openapi_service": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "http://127.0.0.1:8001/mcp", 
        "--transport",
        "streamable-http"
      ]
    }
  }
}
```

#### With Legacy SSE Streaming (Deprecated)
```json
{
  "mcpServers": {
    "streaming_api": {
      "command": "full_path_to_openapi_mcp/venv/bin/python",
      "args": ["full_path_to_openapi_mcp/src/server.py"],
      "env": {
        "SERVER_NAME": "streaming_api",
        "OPENAPI_URL": "https://api.example.com/openapi.json",
        "SSE_ENABLED": "true",
        "SSE_HOST": "127.0.0.1",
        "SSE_PORT": "8001"
      },
      "transport": "stdio"
    }
  }
}
```

Apply this configuration to the following files:

- Cursor: `~/.cursor/mcp.json`
- Windsurf: `~/.codeium/windsurf/mcp_config.json`
- Claude Desktop: `~/Library/Application Support/Claude/claude_desktop_config.json`

> Replace `full_path_to_openapi_mcp` with your actual installation path.

### Quick Setup for Multiple APIs

Copy the provided example configuration:
```bash
cp claude_desktop_config.json ~/Library/Application\ Support/Claude/claude_desktop_config.json
```

Start both services:
```bash
# Terminal 1
source venv/bin/activate && \
OPENAPI_URL="https://api.met.no/weatherapi/locationforecast/2.0/swagger" \
SERVER_NAME="weather" \
MCP_HTTP_ENABLED="true" \
MCP_HTTP_PORT="8001" \
python src/fastmcp_server.py

# Terminal 2  
source venv/bin/activate && \
OPENAPI_URL="https://petstore3.swagger.io/api/v3/openapi.json" \
SERVER_NAME="petstore" \
MCP_HTTP_ENABLED="true" \
MCP_HTTP_PORT="8002" \
python src/fastmcp_server.py
```

Result: Claude gets access to both weather and petstore APIs with prefixed tool names.

## 📁 Loading Local OpenAPI Specifications

You can now load OpenAPI specs from your local filesystem instead of requiring remote URLs:

### JSON Format
```bash
source venv/bin/activate
OPENAPI_URL="./specs/my-api.json" \
SERVER_NAME="local_api" \
python src/fastmcp_server.py
```

### YAML Format  
```bash
source venv/bin/activate
OPENAPI_URL="../shared/api.yaml" \
SERVER_NAME="local_api" \
python src/fastmcp_server.py
```

### Absolute Path
```bash
source venv/bin/activate
OPENAPI_URL="/Users/myuser/projects/api-spec.json" \
SERVER_NAME="local_api" \
python src/fastmcp_server.py
```

### Supported Formats
- **JSON files**: `.json` extension
- **YAML files**: `.yaml` or `.yml` extension  
- **Relative paths**: `./path/to/spec.yaml`, `../spec.json`
- **Absolute paths**: `/full/path/to/spec.yaml`

## 🔑 API Key and Custom Headers

Support for APIs requiring custom headers (API keys, tokens, etc.):

### Using JSON Format
```bash
source venv/bin/activate
MCP_AUTH_HEADERS='{"X-API-Key": "your-api-key", "X-Client-ID": "client123"}' \
OPENAPI_URL="https://api.example.com/openapi.json" \
SERVER_NAME="custom_api" \
python src/fastmcp_server.py
```

### Using Simple Format
```bash
source venv/bin/activate
MCP_AUTH_HEADERS='X-API-Key=your-api-key,X-Client-ID=client123' \
OPENAPI_URL="https://api.example.com/openapi.json" \
SERVER_NAME="custom_api" \
python src/fastmcp_server.py
```

### Common API Key Patterns
- **RapidAPI**: `MCP_AUTH_HEADERS='{"X-RapidAPI-Key": "your-key"}'`
- **Custom Bearer**: `MCP_AUTH_HEADERS='{"Authorization": "Bearer custom-token"}'`
- **Multiple Headers**: `MCP_AUTH_HEADERS='{"X-API-Key": "key", "X-API-Secret": "secret"}'`

### Local Spec + Custom Headers
Combine both features for development:
```bash
source venv/bin/activate
OPENAPI_URL="./test/fixtures/api.json" \
MCP_AUTH_HEADERS='{"X-API-Key": "dev-key"}' \
SERVER_NAME="dev_api" \
python src/fastmcp_server.py
```

## 🛠️ Examples & Use Cases

### Norwegian Weather API
Test with real weather data (no authentication required):

```bash
# Start weather server
source venv/bin/activate && \
OPENAPI_URL="https://api.met.no/weatherapi/locationforecast/2.0/swagger" \
SERVER_NAME="weather" \
MCP_HTTP_ENABLED="true" \
MCP_HTTP_PORT="8001" \
python src/fastmcp_server.py
```

**Available tools:**
- `weather_get__compact` - Weather forecast for coordinates
- `weather_get__complete` - Detailed weather forecast
- `weather_get__status` - Server status

**Example usage in Claude:**
- *"What's the weather in Oslo tomorrow?"* → Uses lat=59.9139, lon=10.7522
- *"Show me detailed weather for Bergen"* → Uses lat=60.3913, lon=5.3221

### Pet Store API
Test with Swagger's demo API:

```bash
# Start petstore server
source venv/bin/activate && \
OPENAPI_URL="https://petstore3.swagger.io/api/v3/openapi.json" \
SERVER_NAME="petstore" \
MCP_HTTP_ENABLED="true" \
MCP_HTTP_PORT="8002" \
python src/fastmcp_server.py
```

**Available tools:**
- `petstore_addPet` - Add a new pet to the store
- `petstore_findPetsByStatus` - Find pets by status
- `petstore_getPetById` - Find pet by ID

    end
```

## Resources & Prompts

The server automatically generates comprehensive metadata to enhance AI integration:

### Resources
- **Schema-based Resources:** Automatically derived from OpenAPI component schemas
- **Structured URIs:** Resources are registered with consistent URIs (e.g., `/resource/{server_name}_{schema_name}`)
- **Type Conversion:** OpenAPI schemas are converted to MCP-compatible resource definitions

## 🔍 Troubleshooting

### Common Issues

**❌ `RequestHandler.prepare_request() missing arguments`**
```bash
# Solution: Use fastmcp_server.py instead of server.py
python src/fastmcp_server.py  # ✅ Correct
```

**❌ Claude Desktop doesn't see the tools**
```bash
# Check configuration location
ls ~/Library/Application\ Support/Claude/claude_desktop_config.json

# Restart Claude Desktop after config changes
```

**❌ Connection refused on port 8001**
```bash
# Check if server is running
lsof -i :8001

# Check server logs for errors
```

**❌ SSL/TLS errors with OpenAPI URLs**
```bash
# Update certificates
pip install --upgrade certifi httpx
```

### Testing Tools

**Test server initialization:**
```bash
python test_weather_oslo.py
```

**Test with mcp-remote:**
```bash
npx mcp-remote http://127.0.0.1:8001/sse
```

**Check available tools:**
```bash
curl http://127.0.0.1:8001/health
```

### Environment Issues

**Python version mismatch:**
```bash
# Ensure Python 3.12+
python --version

# Recreate virtual environment if needed
rm -rf venv && python3.12 -m venv venv
```

**Missing dependencies:**
```bash
# Reinstall requirements
pip install --upgrade -r requirements.txt
```
