Blockscout MCP Server

# Blockscout MCP Server - AI Agent Guide > This server provides blockchain data access via both MCP (Model Context Protocol) and REST API. Choose the interface that best fits your agent's capabilities and integration requirements. ## Enhanced Analysis with Agent Skills For more powerful blockchain analysis, install the **Blockscout Analysis** skill from the [agent-skills repository](https://github.com/blockscout/agent-skills). This skill provides AI agents with structured guidance for execution strategies, response handling, security best practices, and workflow orchestration. See the [agent-skills README](https://github.com/blockscout/agent-skills) for full capabilities and installation instructions. ## Quick Start for AI Agents ### MCP Interface (Recommended for Native MCP Clients) **Best for:** Claude Desktop, Cursor, MCP Inspector, and other native MCP clients **Benefits:** Context-aware, progress tracking, intelligent pagination, optimized for LLM token usage **Authentication:** Tools reach Blockscout data through [the Blockscout PRO API](https://dev.blockscout.com/).
