Glass Bank

A fictional bank you can connect to any MCP client, with an X-ray view of everything the server sees. Every customer, card and transfer here is fake.

Connect an MCP client

MCP server URL:

https://mcp-bank-520283334162.us-central1.run.app/mcp
  1. claude.ai: Customize > Connectors > Add custom connector. Paste the URL above and leave the OAuth client fields empty. A mock bank login opens: pick a demo customer and approve the scopes.
  2. Claude Code: claude mcp add --transport http glassbank https://mcp-bank-520283334162.us-central1.run.app/mcp, then /mcp to log in.
  3. Other clients (Codex, MCP Inspector): Streamable HTTP with OAuth 2.1 and dynamic client registration, at the same URL.

Opening /mcp in a browser answers 405: it speaks MCP over POST only.

Watch it from the inside

The X-ray dashboard shows which tools were listed and called, with their arguments, rationale and results. Once a client is connected, ask it for the X-ray link (the xray_get_session_link tool) to watch your own session live.
