Blockscout MCP Server

Blockscout is an open-source blockchain explorer for inspecting and analyzing EVM-compatible blockchains. This MCP server for Blockscout wraps the official Blockscout multi-chain API, exposing blockchain data - balances, tokens, NFTs, contract metadata - via MCP so that AI agents and tools can access and analyze it contextually.

Features

Blockscout MCP Server provides the following features:

• Chain Information: Get a list of supported blockchains.
• Address and Contract Analysis: Resolve ENS names, get address balances, contract details, and retrieve contract ABIs.
• Token and NFT Data: Look up tokens by symbol, and get detailed information on token holdings and NFTs for a given address.
• Transaction and Block History: Retrieve information on blocks, get transaction history for an address, and get detailed information about specific transactions, including human-readable summaries.
• Event Logs: Get decoded event logs for transactions or addresses.

Usage Guide

The Blockscout MCP Server is in Beta and currently does not require authentication. This is subject to change.

Generate URL

Log in to the Higress MCP Marketplace and generate a URL for either Streamable HTTP or SSE.

Configure MCP Client

In your MCP Client configuration, add the following to the MCP Server list:

"mcpServers": {
    "mcp-blockscout": {
      "url": "https://mcp.higress.ai/mcp-blockscout/{user-specific-id}/sse"
    }
}

or in case of Streamable HTTP:

"mcpServers": {
    "mcp-blockscout": {
      "url": "https://mcp.higress.ai/mcp-blockscout/{user-specific-id}"
    }
}
