The Bankless Onchain MCP server provides a standardized interface for querying blockchain data. It implements the Model Context Protocol to enable AI agents to interact with onchain information across Ethereum-compatible networks. The server focuses on common blockchain queries including token balances, transaction history, and contract state reads.

As part of the MCP ecosystem, this server bridges the gap between AI systems and blockchain data. It follows the protocol’s conventions for exposing onchain capabilities as machine-readable tools. The implementation is community-maintained and open source, hosted under the Bankless GitHub organization.

Developers working on blockchain analytics or automation would use this server to integrate onchain data into agent workflows. It serves as a connector between AI systems and the growing universe of decentralized applications. The tool is particularly relevant for projects needing programmatic access to common Ethereum data types.
