# Handoff: Auth0 Implementation for Point Topic MCP

## Current Status

**Issue #30**: https://github.com/Point-Topic/point-topic-mcp/issues/30  
**Status**: ✅ Implemented (Dev Tenant)  
**Branch**: agent-dev (merged PR #39)

**Auth0 Tenant:** point-topic-dev.eu.auth0.com (development)
**Production tenant:** point-topic.eu.auth0.com (ready for future)

## Current Implementation

Auth0Provider configured with dev tenant credentials:
- Client ID: b9VymHWxP5QOAjrLyiV06pf57Sizi3i3  
- Domain: point-topic-dev.eu.auth0.com
- Audience: http://ss-api
- Callback: https://point-topic-mcp.fastmcp.app/auth/callback

## What We Learned

1. **FastMCP middleware triggers auth flow** - Any middleware that returns `None` or raises auth errors causes opencode to show "needs auth"
2. **PR #39 removed all middleware** - Server currently has NO auth enforcement
3. **Auth0 is the solution** - FastMCP's built-in `Auth0Provider` handles OAuth properly without triggering false auth prompts

## The Plan

1. **Create Auth0 Application** using Auth0 CLI
2. **Implement FastMCP Auth0Provider** in server_http.py
3. **Test OAuth flow** with Cursor IDE on FastMCP Cloud
4. **Document working CLI commands** in infrastructure/auth0-setup.sh

## Auth0 Setup Script

File: `infrastructure/auth0-setup.sh`
- Template created and executable
- Must add working CLI commands here (never run ad-hoc)
- Uses domain: point-topic.eu.auth0.com

## Next Steps

1. Install Auth0 CLI if not already: `brew install auth0`
2. Login: `auth0 login`
3. Create application using CLI
4. Add working commands to infrastructure/auth0-setup.sh
5. Update server_http.py to use Auth0Provider
6. Test with Cursor IDE
7. Verify OAuth flow completes successfully

## Questions for Implementation

- What scopes/permissions do you need? (user:upc-query-agent, admin:upc-query-agent)
- Do you want dual auth (Auth0 + API key) during transition?
- What callback URLs? (FastMCP Cloud vs dedicated server)

Ready to start implementation with fresh context.
