Why export a ChatAgent as an MCP server?

Publishing your ChatAgent as an MCP server turns your agent into a universal AI backend. Any MCP-compatible client (Claude, Cursor, editors, or your own app) can connect, chat, and run tools through your agent as if it were a native API—no custom integration required.

​
Quick Start

Method 1: Use Service Scripts

Scripted Server:
Launch your agent as an MCP server with the ready-made scripts in services/.
Configure your MCP client (Claude, Cursor, etc.) to connect:
mcp_servers_config.json Example
{
  "camel-chat-agent": {
    "command": "/path/to/python",
    "args": [
      "/path/to/camel/services/agent_mcp_server.py"
    ],
    "env": {
      "OPENAI_API_KEY": "...",
      "OPENROUTER_API_KEY": "...",
      "BRAVE_API_KEY": "..."
    }
  }
}
Tip: Just point your MCP client at this config, and it will auto-discover and call your agent!

Method 2: Use `to_mcp()`

Turn any ChatAgent into an MCP server instantly with to_mcp():
agent_mcp_server.py
from camel.agents import ChatAgent

# Create a chat agent with your model
agent = ChatAgent(model="gpt-4o-mini")

# Convert to an MCP server
mcp_server = agent.to_mcp(
    name="demo", description="A demonstration of ChatAgent to MCP conversion"
)

if __name__ == "__main__":
    print("Starting MCP server on http://localhost:8000")
    mcp_server.run(transport="streamable-http")
Supported transports: stdio, sse, streamable-http

What does this unlock?

  • Plug-and-play with any MCP client: Claude, Cursor, editors, automations—just connect and go.
  • Universal API: Your agent becomes an “AI API” for any tool that speaks MCP.
  • Security & Flexibility: Keep control over keys, environments, and agent configs.
