# Signalaf Sigrank MCP server

Source: https://glimind.com/server/mcp-registry%2Fcom.signalaf%2Fsigrank
Registry id: `mcp-registry/com.signalaf/sigrank`
Status: live (checked 2026-10-27T16:06:19.380Z)

## Verdict

Signalaf Sigrank MCP server answered 99.82% of Glimind's liveness checks over 30 days, better than 25% of MCP servers, with 884 ms median handshake and 3 outages in 90 days. Its agent-readiness grade is A (90/100) across 16 tools, costing an agent about 10,809 tokens to load. Checked every few minutes; no tool is ever called.

## Tools (16)

- `benchmark_me`: Answers 'How good am I?' — benchmarks your token cascade against the live field. Takes 4 token pillars (or a codename), computes your cascade, then compares aga
- `compare_to_field`: Creates a 'YOU vs FIELD vs TOP 10% vs TOP 1%' comparison table for your cascade metrics. Takes 4 pillars or a codename, fetches the live leaderboard, and return
- `diagnose_cascade`: Analyzes your token cascade and diagnoses where you're leaking efficiency. Takes 4 token pillars and produces a ranked list of efficiency leaks with severity (c
- `field_anomaly`: Finds unusual operators, metric relationships, and outliers in the live leaderboard — without user prompting. Returns: highest velocity among below-median lever
- `get_leaderboard`: Read the current public SigRank operator leaderboard. Returns ranked operators with Yield, Leverage, class tier, and display name. Profile text fields (display_
- `get_operator`: Read one public operator profile by codename. Returns class tier, rank, percentile, Yield, Leverage, Velocity, and SNR. Profile text fields (display_name, coden
- `get_sigrank_standard_record`: Build a tteop/0.1-draft portable operator record from available token telemetry. Input and output are required; unavailable cache telemetry remains null. Comput
- `operator_gap`: Answers 'What specifically separates operator A from operator B?' — not just 'A has more Yield', but the primary cause, secondary cause, and offsetting weakness
- `operator_signature`: Computes a normalized operating signature from 4 token pillars or a codename. Returns a signature code, a legacy six-label signature_label, dominant trait, and 
- `rank_if`: Answers 'What would it take to reach a target rank?' — takes your current 4 token pillars and a target percentile (e.g. 90 for top 10%), then simulates the smal
- `rank_paste`: Calculate SigRank cascade metrics from four non-negative token counts without submitting data. Returns Yield, Leverage, Velocity, SNR, and 10xDEV. No data is pe
- `rank_windows`: Score up to 4 time windows (7d, 30d, 90d, all-time) in one call. Each window is scored independently with the full cascade (Υ, SNR, Leverage, Velocity, 10xDEV, 
- `self_improve`: Runs the full self-improvement cycle in one call: (1) computes your current cascade from 4 token pillars, (2) diagnoses efficiency leaks, (3) generates ranked i
- `simulate_change`: Prescriptive 'what if' tool — takes your current 4 token pillars and proposed changes, runs the cascade on both, returns the exact Υ Yield delta, class change,
