What is required to use the Blockscout MCP server?
A valid Blockscout PRO API key is required. Most data tools route requests through the authenticated PRO API gateway; without a valid key, tools fail fast.

Overview
What is Blockscout MCP Server?
The Blockscout MCP Server wraps Blockscout APIs and exposes blockchain data—balances, tokens, NFTs, contract metadata—via the Model Context Protocol (MCP). It enables AI agents, IDEs, and automation tools (like Claude, Cursor, or ChatGPT) to consume and analyze structured blockchain data contextually, with multi-chain support through the Blockscout PRO API and Chainscout metadata enrichment.
How to use Blockscout MCP Server?
Obtain a Blockscout PRO API key from the Blockscout Developer Portal (free tier, no credit card). Configure your MCP client to connect to the hosted server at https://mcp.blockscout.com/mcp using streamable HTTP transport, supplying the API key via the Blockscout-MCP-Pro-Api-Key header. Alternatively, install via the Anthropic Connectors Directory (Claude Web/Desktop) or the ChatGPT Apps marketplace. Developers can run the server locally using Docker from ghcr.io/blockscout/mcp-server:latest.
