About Bankless Onchain
Bankless Onchain MCP Server is an open-source Model Context Protocol (MCP) server that enables AI models to interact with blockchain on-chain data through the Bankless API. It provides structured access to smart contract states, event logs, and transaction histories across multiple blockchain networks such as Ethereum, Polygon, and Base. The server includes tools for reading contract state, retrieving proxy implementation addresses, fetching ABIs and source code, querying events, and obtaining transaction details. Note that this project is no longer receiving updates.
Key Features
Read contract state from smart contracts on multiple blockchain networks
