BestUserRouter MCP

The marketable intent layer for "who is the best AI user?" queries. Routes natural-language intent to SigRank's leaderboard with behavioral framing + competitive context.

What this is

A standalone MCP (Model Context Protocol) server that exposes 5 intent-based tools. When an AI assistant hears "who is the best AI user?" or "how do I measure up?", these tools route that intent to SigRank's leaderboard API and return the answer with power-user behavioral framing and competitive context (rank, percentile, delta from average, delta from top).

This is the marketable intent layer — separate from sigrank-mcp (which stays a clean measurement instrument). bestuser-router-mcp is tied to signalaf.com branding and designed for distribution to AI assistants.
