Best for
  • macOS users
  • Developers using Claude Code or Claude Desktop
  • Individuals or teams needing WeChat automation integration
  • Users comfortable with command line and Python environments
  • 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
  • Scenarios needing clean, structured web context fed to an AI assistant
  • Users already on the Firecrawl platform who want to call its scraping capability directly via MCP
Not for
  • Non-macOS platforms (Windows, Linux)
  • Users without WeChat for Mac or accessibility permissions
  • Publishing Moments with media (photos, videos)
  • Users needing cross-device or mobile support
  • 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)
  • Simple static-page scraping where you don't want to depend on a third-party API and incur call costs
  • Sites that explicitly disallow automated access (robots.txt)
Required permissions
  • macOS Accessibility permissions (to control WeChat)
  • WeChat for Mac installed and running
  • 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
  • Requires a Firecrawl API key to call; cost and quota are governed by the Firecrawl account
  • firecrawl_agent/firecrawl_interact perform automated browser interaction, which may trigger login or form-submission flows on the target site
Risks and side effects
  • Relies on macOS Accessibility API, which may be affected by system updates
  • Granting accessibility permissions to terminal poses security risks
  • Changes to WeChat's interface may cause tools to fail
  • Automated actions may violate WeChat's terms of service
  • Accessibility-based control may be detected by WeChat as automation
  • 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
  • Bulk crawl/map tools can generate significant request volume against a target site — respect the site's rate limits and terms of service
  • firecrawl_agent's interactive action chain is longer — define task boundaries clearly before running it to avoid accidentally triggering actions on a sensitive site
