53 tools, live data

Every tool calls the PMAxis REST API in real time. No stale data.

Cursor, Windsurf, and the Python SDK connect via the hosted SSE server and get all 53 tools. The @pmaxis/mcp-servernpm package (used by the Claude Desktop / npm setup above) is on an older release and currently exposes 34 of these — the newer wallet-calibration, wallet-clustering, and orderbook-history tools aren't in it yet. Prefer Cursor/Windsurf/Python if you need full coverage today.
