io.github.junct-bot/blockscout-mcp is a MCP server that delivers 56 tools for Blockscout on-chain data, metrics, and analytics.

About

io.github.junct-bot/blockscout-mcp exposes Blockscout explorer capabilities to MCP clients through fifty-six tools focused on on-chain data, metrics, and analytics. Developers creating wallet apps, indexers, or AI assistants for crypto users can add the streamable-http remote so Claude Code, Cursor, or Codex fetches structured chain intelligence while they implement features or debug production issues. The project ships at version 1.1.0 with documentation and repository links under junct-bot. It complements wallet and smart-contract skills by supplying read-heavy analytics rather than signing or deployment actions. Start using it when you integrate explorer data into a backend or agent toolpath, and keep it registered for operations when you need quick metric lookups during support or monitoring passes without opening multiple explorer tabs.

What it does

Connect your agent to Blockscout on-chain data, metrics, and analytics through 56 MCP tools while building or operating web3 products.

Who is it for?

Best when you're shipping on-chain features, dashboards, or support agents and want Blockscout-grade data without custom indexer infrastructure.

Skip if: Skip if you have no web3 surface area and only need CEX prices or centralized app analytics.

What you get

After adding the Blockscout MCP remote, your agent can query on-chain analytics tools directly while you build integrations or triage live issues.

Integrated Blockscout analytics accessible from agent tool calls
Faster contract and transaction investigation during build and ops
Structured chain metrics for dashboards and support playbooks
