Pump.fun MCP Server

A Cloudflare Worker that implements the MCP Streamable HTTP transport for AI agents to interact with pump.fun on Solana.

Tools (10 read-only tools)

Tool

Description

Or for the path-based gateway pattern (modelcontextprotocol.name/mcp/pump-fun-sdk):

  1. Uncomment the [route] section in wrangler.toml
