The module-level 'import httpx' in auth0.py broke import on a clean install of fastmcp or fastmcp-slim[server]. --------- Co-authored-by: Jeremiah Lowin <153965+jlowin@users.noreply.github.com> |

Auth0 Auth for MCP Example
Protects a FastMCP server with Auth0 Auth for MCP. Auth0 handles OAuth and client registration; FastMCP validates access tokens.
Auth0 setup
- Enable Resource Parameter Compatibility Profile (Settings → Advanced).
- Create an API whose identifier is
http://127.0.0.1:8000/mcp(must match the URL logged at server startup). - Promote your login connections to domain-level (required for third-party DCR clients).
See Auth0's authorization quickstart for details.
Running
export AUTH0_CONFIG_URL="https://YOUR_TENANT.auth0.com/.well-known/openid-configuration"
python server.py
In another terminal:
python client.py
Use 127.0.0.1 consistently — mixing localhost and 127.0.0.1 breaks audience validation.
For troubleshooting (DCR grants, token exchange errors, MCP Inspector), see the Auth0 integration guide.
