Frontrun MCP Server

Give AI agents native access to the Frontrun API. Track what VCs follow on X in real time — detect new follows, convergence signals, and trending companies across your monitored set.

Works with any MCP-compatible client: Claude Code, Claude Desktop, Cursor, Windsurf, and more.
