Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names clearly indicate their primary function (reserves vs. issuer listing)
- Descriptions include usage context ('when an agent needs machine-readable backing data')
- Clear separation between data retrieval and discovery tools
Weaknesses
- Parameter descriptions lack required/optional clarification and contextual guidance
- Some parameter names (e.g., 'sample') are ambiguous in purpose
- Potential overlap in stablecoin_reserves and stablecoin_list_issuers functions
stablecoin_reserves— Parameter definitions lack required/optional status and usage contextstablecoin_reserves— 'sample' parameter name is ambiguous without explanationstablecoin_list_issuers— Could be confused with stablecoin_reserves due to similar domain focus

Advice
Schema compliance
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
- tools/list schema valid
- inputSchema is valid JSON Schema
- Smoke test not run this round
- Cold-start: cold 164ms → warm 159ms (penalty 5ms)
Tools
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
stablecoin_reservesLatest parsed reserve attestation for one stablecoin issuer as JSON: as_of date, total reserves, composition by asset category, attestor, source_url, current on-chain supply (DefiLlama) and the reserve ratio. Use it when an agent needs machine-readable backing data instead of reading the issuer's PDF. Pass symbol (USDC, USDT, ...) or issuer; period=YYYY-MM selects an earlier month. Issuers without a third-party attestation return supply only with confidence 'none'. Paid: $0.02 per call; without credit you get a PAYMENT_REQUIRED result. Set sample=true for a free example response.
symbolstringissuerstringperiodstringsampleboolean
stablecoin_list_issuersFree. Lists every issuer in the registry with symbol, issuer, attestation type, attestor, cadence, source_url and which months are parsed. Call it first to pick a symbol for stablecoin_reserves.
