EigenLayer MCP Server built on Next.js

Features

• Provides EigenLayer documentation to Claude or other AI assistants via MCP
• Runs as a standalone server locally or as a serverless function on Vercel

Inspired by initial testing here. Cloned from Vercel Next.js MCP template

Test the public endpoint with Claude:

1. Add the live URL to Claude via the following command (in any folder):
   claude mcp add --transport sse eigenlayer-mcp-server https://eigenlayer-mcp-server-sand.vercel.app/sse
2. Install Claude Code. Run command claude to enter Claude Code and confirm the mcp server is added
3. Test with a query like "Can you explain how EigenLayer's restaking mechanism works?"
