yieldsentinel

Evaluate a described stablecoin yield position against a research policy (pull). Always pass your policy rules (or a preset). Without a policy, no meaningful check is possible — the verdict will be review/unknown, never ok. Pass poolId from yieldhunter list_yields opportunities[].id (also accepted as opportunityId or id). That id is one market. Required for a real check: policyPreset (treasury-conservative | balanced-research | rwa-selective) and/or minScore / maxRewardShare / excludeCategories / maxExitRisk / requireCurated. Presets: treasury-conservative | balanced-research | rwa-selective. rwa-selective does not exclude RWA but is not a free pass (YS policy allowlist + higher bar). requireCurated uses the Yieldsentinel policy allowlist (curated.json), not yieldhunter scoring priors. Scoring ≠ policy approval. Fetches live yieldhunter research (score, APY, TVL, category, rewardShare, exitRisk) and curated flags, then returns a PolicyVerdict plus A2H (summary, suggestedNextSteps, legend). Incomplete or missing data is review/unknown — never a silent ok. A verdict is not an exit signal or execution order. Research only — never holds keys. Example: { "poolId": "43641cf5-a92e-416b-bce9-27113d3c0db6", "policyPreset": "treasury-conservative", "notionalUsd": 10000 }

Liveness and capability check for yieldsentinel (yieldsentinel.eth). Returns service status, package version, health schemaVersion (separate from the tool-envelope schemaVersion), policyVersion, feature flags, and the list of available tools. toolStats counts all origins. toolStatsExternal is the external bucket. toolStatsInternal is the internal-test bucket. Send header X-YHYS-Test: 1 on every request (initialize, notifications, and each tools/call). On this stateless server that header is the only working internal-test marker. clientInfo.name prefixes yhys-qa / yhys-feel count only for the same request they appear in. May refresh research vintage via a yieldhunter health ping; a verdict still requires check_position. YH healthy ≠ YS ok. Use this first to verify connectivity, then call check_position with policyPreset treasury-conservative | balanced-research | rwa-selective (or explicit thresholds). Research estimates only — non-custodial; never holds keys or executes transactions. Example input: {}
