MCP Setup

Connect Codex to XandaCross

Use the MCP client’s normal OAuth flow. The user chooses exactly one brain during authorization.

First-time setup

codex mcp add xandacross \
  --url https://xandacross.himeshbhowmik.com/mcp

If this command opens the browser and finishes with Successfully logged in, the connection is already complete.

Use login only later

codex mcp login xandacross

Use this only when credentials are missing, expired, revoked, or after you intentionally logged out.

Verify read-only access

Use the xandacross MCP server.
Call get_zen_identity and sources_list.
Tell me:
- authorized brain/source name
- source_id
- page count
- chunk count
Read-only only.
