Implementation Steps

​
1. Set Up Your Project

mkdir my-lyzr-mcp-server
cd my-lyzr-mcp-server
python -m venv venv
source venv/bin/activate

3. Create the Server

from mcp.server.fastmcp import FastMCP
from starlette.applications import Starlette
from mcp.server.sse import SseServerTransport
from starlette.requests import Request
from starlette.routing import Mount, Route
import uvicorn
import requests
import json
from uuid import uuid4
import os

# Initialize FastMCP server
mcp = FastMCP("lyzr-mcp-server")

LYZR_API_KEY = os.getenv("LYZR_API_KEY")

@mcp.tool()
async def lyzr_chat_api(agent_id: str, message: str) -> str:
    url = "https://agent-dev.test.studio.lyzr.ai/v3/inference/chat/"
    payload = json.dumps({
        "user_id": "user@email.com",
        "agent_id": agent_id,
        "session_id": str(uuid4().hex),
        "message": message
    })
    headers = {
        'Content-Type': 'application/json',
        'x-api-key': LYZR_API_KEY
    }
    response = requests.post(url, headers=headers, data=payload)
    return response.text


def create_app():
    sse = SseServerTransport("/messages/")

    async def handle_sse(request: Request):
        async with sse.connect_sse(request.scope, request.receive, request._send) as (read, write):
            await mcp._mcp_server.run(read, write, mcp._mcp_server.create_initialization_options())

    return Starlette(
        routes=[
            Route("/sse", endpoint=handle_sse),
            Mount("/messages/", app=sse.handle_post_message),
        ],
    )

if __name__ == "__main__":
    app = create_app()
    uvicorn.run(app, host="0.0.0.0", port=8080)

​
4. Run Your Server

export LYZR_API_KEY="your-real-key-here"
python server.py
