# Bankless Onchain

> Use this tool when you need to integrate AI models with blockchain data, enabling interactions with smart contracts and access to transaction information across multiple networks. It solves problems in blockchain analysis, smart contract interaction, and on-chain data exploration by providing a middleware layer that fetches events and contract state. The tool requires a Bankless API token as input and outputs contract data, event logs, and transaction history, making it ideal for workflows that involve blockchain data analysis and automation.

## Description

Bankless Onchain MCP Server provides a middleware between AI models and blockchain data, enabling LLMs to interact with smart contracts, fetch events, and access transaction information across multiple networks. Developed by Bankless Engineering, it implements tools for reading contract state, retrieving proxy implementations, fetching ABIs and source code, filtering event logs, and accessing transaction history. The server requires a Bankless API token for authentication and is particularly valuable for blockchain analysis, smart contract interaction, and on-chain data exploration workflows without requiring users to leave their conversation interface.
