Add timeout configuration for HTTP request

[osushinekotan]

Is your feature request related to a problem? Please describe.
When using FastAPI-MCP to create tools for API endpoints that take longer than 5 seconds to respond, the requests timeout. Currently, the library uses httpx for making HTTP requests, which has a default timeout of 5 seconds, but there is no way to customize this timeout setting at the library user level.

This becomes problematic in production environments where some endpoints might perform complex operations that legitimately take longer than 5 seconds to complete.

Describe the solution you'd like
Add a timeout parameter to the relevant functions in the FastAPI-MCP library:

• create_mcp_tools_from_openapi
• create_http_tool
• mount_mcp_server
• add_mcp_server

This parameter would then be passed to the httpx client when making requests:

async with httpx.AsyncClient(timeout=timeout) as client:
    # existing code

This would allow users to customize timeout settings according to their specific API requirements.

Hey @osushinekotan thanks :)
Small issue though, the PR you posted isn't relevant anymore since we have just published a refactor, so the library works differently now.
But - now there is an option to inject your own httpx client, like so:

from fastapi import FastAPI
from fastapi_mcp import FastApiMCP
import httpx

app = FastAPI()
mcp = FastApiMCP(app, http_client=httpx.AsyncClient(timeout=10))

Does that help?

Yes, this helps a lot! Thank you for letting me know about this.
Having the option to inject your own httpx client is excellent. Being able to customize things like timeout settings is very useful.
