Tools (38)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • polar_agent_manifestPolar Agent Manifestread-only

    Machine-readable install, runtime and client guidance for AI agents. Does not call Polar or expose secrets.

  • polar_cache_statusPolar Cache Statusread-only

    Show optional local SQLite cache status. Enable with POLAR_CACHE=sqlite or POLAR_CACHE=true.

  • polar_capabilitiesPolar MCP Capabilitiesread-only

    Explain supported Polar data, privacy boundaries, recommended agent workflow and project links.

  • polar_connection_statusPolar Connection Statusread-only

    Check local Polar config, token file, Node version, privacy mode, cache readiness and optional MCP client readiness without calling Polar or exposing secrets.

  • polar_daily_summaryPolar Daily Training Summaryread-only

    Build a practical daily summary from Polar sleep, activity, Nightly Recharge and training data when available. Read-only and non-medical.

  • polar_data_inventoryPolar Data Inventoryread-only

    Inventory supported Polar data domains, auth scope requirements, privacy boundary and recommended first calls. Does not call Polar APIs or expose user data.

  • polar_demoPolar Demoread-only

    Returns realistic example payloads of polar_daily_summary, polar_wellness_context, and polar_list_nightly_recharge so agents see the contract before calling real Polar APIs.

  • polar_exchange_codeExchange Polar OAuth Code

    Exchange a Polar OAuth authorization code for local tokens. Tokens are stored locally with 0600 permissions and are never returned. Requires explicit user action: the user must complete browser OAuth and supply the authorization code (agents must not invent codes).

  • polar_get_account_dataPolar Account Dataread-only

    Read Polar user account fields exposed by AccessLink. Requires profile:read.

  • polar_get_auth_urlGet Polar OAuth URLread-only

    Generate a Polar OAuth authorization URL. Use this first when no local token exists.

  • polar_get_routePolar Routeread-only

    Load a Polar route by route id. Routes are GPS-sensitive; default privacy modes redact coordinates. Requires routes:read.

  • polar_heart_seriesPolar Heart Seriesread-only

    Description is built at runtime.

  • polar_list_activityPolar Daily Activityread-only

    List Polar daily activity records. Requires activity:read.

  • polar_list_calendarPolar Calendarread-only

    List Polar calendar entries in a date range. Requires calendar:read.

  • polar_list_continuous_samplesPolar Continuous Samplesread-only

    List continuous sample records for a date range. Requires continuous_samples:read. Prefer polar_heart_series for agent-safe bounded HR series. Not medical advice.

  • polar_list_user_devicesPolar User Devicesread-only

    List devices registered to the Polar user. Requires devices:read.

  • polar_onboardingWellness Onboarding Flowread-only

    Read-only. Return the 11-question Delx Wellness onboarding flow (en or pt-BR), the current shared profile, missing critical fields, and a cross-connector hint. Use this when the user starts a fresh wellness session and you need to fill out preferred_name, goals, devices, training context, nutrition, preferences, and safety.

  • polar_privacy_auditPolar Privacy Auditread-only

    Return local privacy, cache, token-path and env-presence posture without revealing secret values.

  • polar_profile_getGet Shared Wellness Profileread-only

    Read the canonical Delx Wellness profile shared with the other wellness MCP connectors (Nourish, Cycle Coach, CGM, etc.). Read-only. Profile stores only what the user typed during onboarding — never OAuth tokens, API keys, or biomarkers.
