`fastmcp.server.auth.providers.auth0`

Auth0 OAuth providers for FastMCP. This module provides two Auth0 integrations:

Auth0Provider — OAuth proxy for fixed Auth0 application credentials
Auth0MCPProvider — resource server for Auth0 Auth for MCP (DCR/CIMD)

Example (OAuth proxy):

from fastmcp import FastMCP
from fastmcp.server.auth.providers.auth0 import Auth0Provider

auth = Auth0Provider(
    config_url="https://auth0.config.url",
    client_id="your-auth0-client-id",
    client_secret="your-auth0-client-secret",
    audience="your-auth0-api-audience",
    base_url="http://localhost:8000",
)

mcp = FastMCP("My Protected Server", auth=auth)

Example (Auth for MCP):

from fastmcp import FastMCP
from fastmcp.server.auth.providers.auth0 import Auth0MCPProvider

auth = Auth0MCPProvider(
    config_url="https://your-tenant.auth0.com/.well-known/openid-configuration",
    base_url="http://127.0.0.1:8000",
)

mcp = FastMCP("My MCP Server", auth=auth)

Classes

`Auth0Provider`

An Auth0 provider implementation for FastMCP. This provider is a complete Auth0 integration that’s ready to use with just the configuration URL, client ID, client secret, audience, and base URL.

`Auth0JWTVerifier`

JWT verifier for Auth0 MCP access tokens. Auth0’s rfc9068_profile_authz token dialect exposes API permissions in the permissions claim. Standard OAuth scope/scp claims are checked first; permissions is included when present.

`Auth0MCPProvider`

Auth0 resource server provider for Auth for MCP (DCR/CIMD). FastMCP validates access tokens issued by Auth0 while Auth0 handles OAuth, dynamic client registration, and CIMD approval in the tenant dashboard. Enable the Resource Parameter Compatibility Profile in Auth0 and create an API whose identifier matches this server’s resource URL (logged at startup). Methods:

`set_mcp_path`

set_mcp_path(self, mcp_path: str | None) -> None

Bind the default verifier’s audience to this server’s resource URL.

`get_routes`

get_routes(self, mcp_path: str | None = None) -> list[Route]

Protected resource routes plus Auth0 authorization server metadata.
