Best for
  • Developers
  • Data analysts
  • Marketers needing real-time Twitter account monitoring
  • AI assistant users integrating Twitter data into workflows
  • 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 do not need Twitter data
  • Users requiring data from X's official API rather than a third-party API
  • Users concerned about sending data to a third-party service
  • 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
  • Network access to connect to api.6551.io and wss://ai.6551.io
  • API token from environment variable or config.json
  • No file system writes or other local system permissions
  • 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
  • Dependence on third-party API service for data
  • Token leakage could lead to unauthorized usage
  • API service may become unavailable or change
  • Data may be incomplete or delayed as it is not from an official source
  • 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
