What it does
Sigrank is an MCP server that exposes the SigRank leaderboard and Upsilon measurement engine for evaluating AI operator efficiency. It provides access to cascade metrics, operator rankings, profiles, and diagnostic tools for analyzing token-processing patterns. It is for developers integrating AI operator evaluation and efficiency benchmarking into their applications.
- Query the SigRank leaderboard to retrieve ranked operators and their yield metrics.
- Calculate Yield scores from token counts (cache read, output, input) to measure cascade efficiency.
- Access operator profiles and diagnostic data to analyze token-processing patterns and efficiency.
Tools this server exposes
| Tool | Does |
|---|---|
| calculate_yield | Calculate Yield metric from four token counts using the formula Υ = (cache_read × output) / input². |
| get_leaderboard | Retrieve the SigRank leaderboard with operator rankings sorted by Yield. |
| get_operator_profile | Fetch an operator's profile including cascade layer, class, fingerprint, and historical metrics. |
| run_diagnostics | Execute diagnostic analysis on token cascade efficiency and signal compounding patterns. |
Before you enable it
An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
