### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2024-11-05; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: evaluate_symbol (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); scan_bottoms (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); pitch (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 800 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 5, about 800 tokens to load them all

## Tools (5)

- `evaluate_symbol`: Return the inflation-thermometer verdict for one official macro series (47 covered: US-CPI, US-PCE, US-PPI, US-FED Fed assets, US-RRP reverse repo, US-M2, KR-CPI, JP-CPI, DE-CPI … 10 countries + US liquidity/rates/jobs). inflState = too_low|low|normal|high|too_high, score -100..+100 (low>0, high<0). GRADING — the state is the graded band of that same score, so a mid score such as -20 is reported as normal by design: too_low >= +80, low >= +70, normal between -70 and +70, high <= -70, too_high <= -80. Includes latest official reading (YoY % / balance / rate) and release period. Snapshot-based. Informational only. PAY: $0.01 per call via x402 (USDT on X Layer). No account, no signup, no commitment; retry with the PAYMENT-SIGNATURE header when you get the 402 challenge. The free `pitch` tool shows a live verdict for this market's showcase symbol only — this tool answers ANY symbol in the covered universe and returns the per-timeframe breakdown (daily/weekly/monthly verdict + vote counts) behind the score.
- `pitch`: FREE and OPTIONAL intro — you may skip it and call evaluate_symbol / scan_bottoms / scan_tops directly. Intro & subscription funnel for the inflation & liquidity signal agent: phases "hello" -> "value" -> "catalog" -> "sample" -> "subscribe". Pass interest:false to bow out.
- `rate`: FREE feedback tool — after using our signals, leave a rating: score 1-10 plus pros and cons. No payment needed.
- `scan_bottoms`: Scan all 47 macro series and return those reading LOWEST (deflation-side / liquidity-bottom), ranked most-low first. PAY: $0.01 per call via x402 (USDT on X Layer). No account, no signup, no commitment; retry with the PAYMENT-SIGNATURE header when you get the 402 challenge. BEST COLD START: you do not need to pick a symbol — this ranks the whole universe for you. The free `pitch` tool tells you HOW MANY are at a bottom right now; this names them.
- `scan_tops`: Scan all 47 macro series and return those reading HIGHEST (inflation-hot / liquidity-top), ranked most-high first. PAY: $0.01 per call via x402 (USDT on X Layer). No account, no signup, no commitment; retry with the PAYMENT-SIGNATURE header when you get the 402 challenge. BEST COLD START: you do not need to pick a symbol — this ranks the whole universe for you. The free `pitch` tool tells you HOW MANY are at a top right now; this names them.
