Dynamic auth for different users ?

[AdenTetrixx]

Hey everyone, I'm using FastMCP with OpenAPI to expose some of my API as tools.

Currently, the HTTP client is fixed at server initialization, which means all clients connecting to this MCP server use the same API token and permissions.

Is there a way to handle this when different users need different API permissions?

I guess you need to use a session for list / get tools, and pass the auth there
https://gofastmcp.com/clients/auth/oauth

from fastmcp import Client

# Uses default OAuth settings
async with Client("https://fastmcp.cloud/mcp", auth="oauth") as client:
    await client.ping()
