Etherscan has launched a Claude Connector that allows users to query blockchain data using natural language prompts. The integration supports over 60 EVM-compatible chains, enabling users to request transaction histories and token data without requiring an API key or an account.
Why it matters
This development simplifies blockchain analysis by removing the need for technical proficiency in block explorers or manual data filtering. By enabling natural language interaction, Etherscan is reducing the barrier to entry for users investigating wallet balances and contract event logs.
The connector provides read-only access to transaction history, gas prices, and contract data for ERC-20, ERC-721, and ERC-1155 token standards. Users can access these metrics across 60 chains through a keyless interface that provides direct verification links back to Etherscan records.
The players
Etherscan
A block explorer and analytics platform that provides search and retrieval services for Ethereum and other EVM-compatible blockchain data.
Claude
An AI platform developed by Anthropic, designed to process natural language inputs and integrate with external data through protocols like the Model Context Protocol.
The details
The integration leverages a Model Context Protocol (MCP) server, an open standard that allows AI models to communicate with local or remote data sources. By processing natural language prompts, the model translates user requests into specific queries that the Etherscan API understands. It operates in a read-only, keyless environment, meaning it can fetch data but cannot sign or initiate transactions on the blockchain.
Timeline
August 2026: Etherscan deployed a Model Context Protocol server.
September 2026: The Claude Connector appeared in the marketplace directory.
October 21, 2026: The Claude Connector reached general availability.
The Tech Race
This integration follows the broader adoption of the Model Context Protocol, which aims to standardize how AI models interface with external databases and tools. By enabling direct natural language queries on blockchain data, Etherscan is shifting the competitive baseline for block explorer accessibility.
Users can now retrieve wallet balances and transaction histories without needing to manage API keys or create accounts on blockchain analytics platforms. The tool works for ERC-20, ERC-721, and ERC-1155 tokens, providing read-only insights that are automatically linked back to Etherscan for verification.
The takeaway
The move to natural language blockchain queries marks a significant shift toward abstracting technical data retrieval for non-specialist users. Watch for similar integrations across other data-heavy platforms as the Model Context Protocol continues to expand its supported ecosystem.
