Generate openapi.json

[rainer85ah]

Hi there,

I have a simple question. What is the simplest or best way to generate an openapi.json file from a mcp server app?

My setup include 3 docker containers with ollama, open-webui, and my mcp-server, which it can talk to ollama without problems, but I can't add my mcp server to the open-webui tools because there is no openapi.json file available.

In the docs, there is information of creating a mcp server from a fastapi app or openapi.json, but what I need is going from mcp-server app to fastapi app or generate the openapi.json file.

All suggestions are welcome.

`import asyncio
import logging
from fastmcp import FastMCP
from tools.general import *

logger = logging.getLogger("MainAgent")
mcp = FastMCP(name="MainAgent")
mcp.dependencies = []

async def main():
logger.info(f"Mounting Sub-Agents ...")
mcp.mount(prefix='general', server=general_mcp)

logger.info(f"Starting Main MCP server...")
try:
    await mcp.run_async(
        transport="streamable-http",
        host="0.0.0.0",
        port="8000",
        path="/mcp"
    )
except Exception as e:
    logger.exception("Fatal error in MCP server")
finally:
    logger.info("MCP server shutdown complete.")

if name == "main":
asyncio.run(main())`
