MCP ​

For MCP transport/auth/resources and tools, see /common/mcp.html.

Scope: contract-only (no internal infra/storage/alarms). Canonical protocol lives at https://mcp.g3nretailstack.com/rbs/PROTOCOL.md and is mirrored here at /rbs/PROTOCOL.md. MCP server endpoint: https://api.mcp.g3nretailstack.com/mcp (CloudFront mcp.g3nretailstack.com/mcp 307-redirects there).

Quick checks (once published) ​
