Poe Proxy MCP Server

A FastMCP server that proxies the Poe.com API, exposing tools for querying Poe models and sharing files. This server is specifically designed to ensure compatibility with Claude 3.7 Sonnet and other models available through Poe.

Features

Multiple Model Support: Query various models available on Poe including GPT-4o, Claude 3 Opus, Claude 3 Sonnet, Gemini Pro, and more
Claude 3.7 Sonnet Compatibility: Special handling for Claude's thinking protocol
File Sharing: Share files with models that support it
Session Management: Maintain conversation context across multiple queries
Streaming Responses: Get real-time streaming responses from models
Web Client Support: Use the server with web clients via SSE transport

Installation

Prerequisites

Python 3.8 or higher
A Poe API key (get one from Poe.com)

Quick Installation

Use the provided installation script:

git clone https://github.com/Anansitrading/poe-proxy-mcp.git
cd poe-proxy-mcp
chmod +x install.sh
./install.sh

The script will:

Create a virtual environment
Install all dependencies
Create a .env file if it doesn't exist
Set up the server for both STDIO and SSE transports

Manual Setup

If you prefer to set up manually:

Clone this repository:
git clone https://github.com/Anansitrading/poe-proxy-mcp.git cd poe-proxy-mcp
Create a virtual environment and install dependencies:
python -m venv venv source venv/bin/activate # On Windows: venv\Scripts\activate pip install -r requirements.txt
Create a .env file with your Poe API key:
cp .env.example .env # Edit .env with your API key

Installation as a Package

You can also install the server as a Python package:

pip install -e .

This will make the poe-mcp and poe-mcp-sse commands available in your environment.

Configuration

The server can be configured using environment variables:

Variable	Description	Default
`POE_API_KEY`	Your Poe API key (required)	None
`DEBUG_MODE`	Enable verbose logging	`false`
`CLAUDE_COMPATIBLE`	Enable Claude compatibility mode	`true`
`MAX_FILE_SIZE_MB`	Maximum file size for uploads	`10`
`SESSION_EXPIRY_MINUTES`	Session expiry duration in minutes	`60`

Usage

Running the Server

Standard Mode (STDIO)

This is the default mode and is suitable for command-line usage:

# If installed as a package:
poe-mcp

# Or directly:
python poe_server.py

Web Mode (SSE)

This mode enables the server to be used with web clients:

# If installed as a package:
poe-mcp-sse [port]

# Or directly:
python run_sse_server.py [port]

The server will start on port 8000 by default, or you can specify a different port.

Available Tools

The server exposes the following tools:

`ask_poe`

Ask a question to a Poe bot.

response = await mcp.call("ask_poe", {
    "bot": "claude",  # or "o3", "gemini", "perplexity", "gpt"
    "prompt": "What is the capital of France?",
    "session_id": "optional-session-id",  # Optional
    "thinking": {  # Optional, for Claude models
        "thinking_enabled": True,
        "thinking_depth": 2
    }
})

`ask_with_attachment`

Ask a question to a Poe bot with a file attachment.

response = await mcp.call("ask_with_attachment", {
    "bot": "claude",
    "prompt": "Analyze this code",
    "attachment_path": "/path/to/file.py",
    "session_id": "optional-session-id",  # Optional
    "thinking": {  # Optional, for Claude models
        "thinking_enabled": True
    }
})

`clear_session`

Clear a session's conversation history.

response = await mcp.call("clear_session", {
    "session_id": "your-session-id"
})

`list_available_models`

List available Poe models and their capabilities.

response = await mcp.call("list_available_models", {})

`get_server_info`

Get information about the server configuration.

response = await mcp.call("get_server_info", {})

Web Client

A simple web client is included in the examples directory. To use it:

Start the server in SSE mode:
python run_sse_server.py
Open examples/web_client.html in your browser.
Enter the server URL (default: http://localhost:8000) and click "Get Available Models".
Select a model, enter your prompt, and click "Submit".

Examples

Simple Query

# examples/simple_query.py
import asyncio
from fastmcp import MCPClient

async def main():
    client = MCPClient("http://localhost:8000")
    
    response = await client.call("ask_poe", {
        "bot": "claude",
        "prompt": "Explain quantum computing in simple terms"
    })
    
    print(f"Session ID: {response['session_id']}")
    print(f"Response: {response['text']}")

if __name__ == "__main__":
    asyncio.run(main())

File Attachment

# examples/file_attachment.py
import asyncio
from fastmcp import MCPClient

async def main():
    client = MCPClient("http://localhost:8000")
    
    response = await client.call("ask_with_attachment", {
        "bot": "claude",
        "prompt": "Analyze this code and suggest improvements",
        "attachment_path": "examples/simple_query.py"
    })
    
    print(f"Session ID: {response['session_id']}")
    print(f"Response: {response['text']}")

if __name__ == "__main__":
    asyncio.run(main())

Claude Compatibility

This server includes special handling for Claude models, particularly Claude 3.7 Sonnet, which requires specific formatting for the thinking protocol. When using Claude models:

The server automatically detects Claude models and applies the appropriate formatting.
You can enable the thinking protocol by providing a thinking parameter:
"thinking": { "thinking_enabled": True, "thinking_depth": 2, # Optional, default is 1 "thinking_style": "detailed" # Optional }
If the thinking protocol fails, the server will automatically retry without it.

Testing

To run the test suite:

python run_tests.py

For verbose output:

python run_tests.py --verbose

Troubleshooting

Common Issues

Authentication Error: Make sure your Poe API key is correct in the .env file.
Connection Error: Check that you can access Poe.com from your network.
File Upload Error: Ensure the file exists and is within the size limit.
Claude Thinking Protocol Issues: If you encounter errors with Claude's thinking protocol, try disabling it by setting CLAUDE_COMPATIBLE=false in your .env file.

Debugging

Enable debug mode by setting DEBUG_MODE=true in your .env file for more detailed logs.
