pulse_cohort_summary

Instructions

Implementation Reference

• src/index.ts:394-402 (registration)

  Registration of the pulse_cohort_summary tool via server.registerTool(). Maps to API endpoint /pulse/cohorts/summary. Accepts only useToonFormat input.

  // ══════════════════════════════════════════════════════════
  if (shouldRegister("pulse_cohort_summary")) server.registerTool(
    "pulse_cohort_summary",
    {
      description: "Get behavioral cohort analysis across every tracked wallet on Hyperliquid. Returns PnL tiers (money_printer, smart_money, grinder, humble_earner, exit_liquidity, semi_rekt, full_rekt, giga_rekt) and size tiers (leviathan, tidal_whale, whale, etc). Each tier shows wallet count, avg PnL, avg win rate, and total volume. This is unique intelligence nobody else has. For the current tracked-wallet total, call pulse_global_stats first.",
      inputSchema: { useToonFormat: useToonFormatSchema },
    },
    async ({ useToonFormat }) => toolResult(await callAPI(useToonFormat, "/pulse/cohorts/summary"))
  );

• src/index.ts:401-401 (handler)

  Handler function for pulse_cohort_summary. Calls the API at /pulse/cohorts/summary with optional toon format encoding and wraps result via toolResult().

  async ({ useToonFormat }) => toolResult(await callAPI(useToonFormat, "/pulse/cohorts/summary"))

• src/index.ts:399-399 (schema)

  Input schema for pulse_cohort_summary. Only accepts a single optional boolean 'useToonFormat' (default true) for compact toon format output.

  inputSchema: { useToonFormat: useToonFormatSchema },

• src/index.ts:94-166 (helper)

  Generic API helper used by the handler to make HTTP requests to the Coinversa backend with timeout, retry logic, and error handling.
