Defi MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 116 installs a week from pypi. Last commit 24 Jun 2026.
AI agent access to on-chain DeFi data on Polygon & Arbitrum: balances, positions, prices.
Today is the operative word: we check Defi MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
POLYGON_RPC_URL (RPC URL for Polygon (e.g. from Alchemy or Infura)), ARBITRUM_RPC_URL (RPC URL for Arbitrum One (e.g. from Alchemy or Infura)).
