Indexing Co

About

This tool serves as an MCP server that integrates real-time blockchain data into your Claude Code sessions. Instead of relying on traditional database setups and separate queries, it subscribes to Indexing Co pipeline events via WebSockets, storing them in a local SQLite database. This allows Claude Code to directly query, analyze, and react to live on-chain data, providing a dynamic environment for AI agents to process blockchain information as it happens.

Key Features

• 0 GitHub stars
• Execute read-only SQL queries with `json_extract()` support on raw event data.
• Auto-discover data shape from stored events with `describe_data` tool.
• Store real-time events in a local SQLite database for efficient querying.
• Manage subscriptions to multiple blockchain data channels.
• Stream live blockchain data directly to Claude Code via WebSockets.
• Auto-reconnect with exponential backoff for stable connections.

Use Cases

• Analyze live blockchain transactions and events within Claude Code sessions.
• Develop AI agents that react to and process dynamic blockchain data streams in real-time.
• Monitor specific on-chain activities, such as token transfers or contract interactions.
