This server enables AI assistants to interact with Polygon through a standardized interface, offering comprehensive tools for wallet operations, smart contract deployment, L2 bridging, DeFi interactions, and transaction simulations.”
The project provides a local client configuration using node. Follow the repository’s build and installation steps before copying it, and replace example paths with the paths on your own computer.
The example declares POLYGON_MAINNET_RPC, POLYGON_AMOY_RPC, ETHEREUM_RPC_URL, POLYGONSCAN_API_KEY, PRIVATE_KEY, DEFAULT_NETWORK, DEFAULT_SLIPPAGE, DEFAULT_DEADLINE_MINUTES. Secret-looking values have been replaced with placeholders. Required and optional labels are shown only when the documentation states them.
