Summary
A wallet your assistant can actually use.
Four tools, one of which is a general contract call — so beyond the built-in token operations, anything on Polygon with a published ABI is reachable in the same conversation.
What it is
An onchain client for the Polygon PoS blockchain. It reads ERC-20 balances and the current gas price, transfers tokens, and calls any contract function you can give it an ABI for.
What you get
- The balance of any ERC-20 token on Polygon PoS
- An ERC-20 transfer to an address you name
- The current gas price, before you decide whether to send now
- Any contract function called by name with its arguments and ABI, and MATIC attached if the call needs value
Requirements
Node and a local build. The server holds a twelve-word seed phrase in its environment and signs with it, so the transfer and contract-call tools spend from that wallet directly.
Setup effort
One command plus a key — npx -y polygon-mcp, then supply credentials
