Blockscout Mcp Server
Let your coding agent query on-chain balances, contracts, and Blockscout-indexed chain data while you build or debug Web3 features.
Overview
Blockscout MCP Server is a MCP server for the Build phase that gives AI agents contextual access to Blockscout blockchain and balance data via Smithery.
What is this MCP server?
- Contextual blockchain data for LLMs and automation (balances and related explorer context)
- Hosted streamable HTTP MCP on Smithery with Bearer auth
- Backed by Blockscout open-source explorer stack (GitHub: blockscout/mcp-server)
- Suited to agent-driven debugging of txs, addresses, and chain state
- Remote endpoint v1.13.1 schema—no local chain node required for many queries
- Server package version 1.13.1 on Smithery
- Single streamable-http remote endpoint on server.smithery.ai
- Open-source repository at github.com/blockscout/mcp-server
Community signal: 40 GitHub stars.
What problem does it solve?
Agents cannot see chain state unless you paste explorer screenshots or hand-roll RPC calls for every question.
Who is it for?
Solo builders shipping Web3 dashboards, support agents, or internal tools that need explorer-grade reads without maintaining a full indexer.
Skip if: Teams with zero on-chain surface area or those who already standardize on a single proprietary RPC with no Blockscout deployment.
What do I get? / Deliverables
Your agent can pull Blockscout-backed blockchain context in-thread while you integrate or debug on-chain features.
- Live MCP connection to Blockscout contextual blockchain tools
- In-chat chain and balance lookups for integration and debug sessions
- Reduced manual explorer context copying for agent workflows
Recommended MCP Servers
Journey fit
Blockchain lookups belong in Build when you wire wallets, explorers, and on-chain workflows into the product—not in early idea research alone. Integrations is the shelf for MCP bridges that connect agents to external APIs like Blockscout explorers.
How it compares
On-chain data MCP integration, not a brainstorming or deployment skill.
Common Questions / FAQ
Who is Blockscout MCP Server for?
Indie and solo developers building agent-assisted Web3 apps who use Blockscout or compatible explorers and want chain data inside Claude Code or Cursor.
When should I use Blockscout MCP Server?
Use it during Build integrations when you need balances, address context, or explorer-linked data while coding agents, backends, or ops automations.
How do I add Blockscout MCP Server to my agent?
Register the Smithery remote MCP URL for @blockscout/mcp-server, set Authorization to Bearer your smithery_api_key, and connect from Claude Code, Cursor, or any MCP client that supports streamable HTTP.
