Option A: Build an MCP server that connects to your own data and implements at least one of the security features we've covered in this workshop

If you have an existing graph in GraphOS, now's a great time to try building an MCP server that connects to it.

Implement at least one of the security features we've covered in this workshop to secure the MCP server: auth, operation collections, or persisted queries.

Option B: Expand the current MCP server

Let's go beyond just the listings subgraph. You can access:

• the graph's full schema
• a visualization of the graph's schema

Which fields should be protected from unauthorized access? Which fields should only be accessible to hosts? Which fields should only be accessible to guests?

Discuss with your neighbor. Implement at least one change to the MCP server.
