Best for
  • Users with supported Whisker devices who want natural-language management through Claude Desktop.
  • Households that need to monitor or manage multiple Litter-Robot or Feeder-Robot devices.
  • Hevy PRO users who want AI assistants to directly access their workout data
  • People who prefer using MCP clients like Claude, Cursor, Codex for fitness tracking
  • Anyone needing summaries and insights from their training data
Not for
  • Users who require an official Whisker API or an officially maintained server.
  • Devices or features not listed as supported in the README, including Litter-Robot 5 cameras.
  • Users unwilling to provide Whisker account credentials or accept experimental API risk.
  • Users without a Hevy PRO subscription (API key required)
  • Users who want to use the server without an API key
  • Those needing delete workflows (Hevy API does not expose delete endpoints)
Required permissions
  • Requires the Whisker account username and password.
  • Requires access to robots associated with the account, including their status, activity, pet, and settings data.
  • Control tools may start cleaning, reset devices, dispense snacks, or change device settings.
  • Requires HEVY_API_KEY environment variable for Hevy API authentication
  • Can create, update, and replace workouts, routines, folders, templates, and body measurements via tools
  • Read operations can fetch workouts, routines, folders, templates, history, and user info
Risks and side effects
  • The API is unofficial and experimental, reverse-engineered from network traffic and the Whisker app; it may stop working at any time.
  • The Claude Desktop example stores credentials in plaintext, so weak file permissions could expose them.
  • Control tools operate real pet devices; verify the target robot and requested action before execution.
  • API key can be misused if leaked; do not expose in URLs, logs, or screenshots
  • Create operations may produce duplicates on retry; update operations replace existing records
  • The server sends data to the Hevy API and may send telemetry to external services unless disabled
