Best for
  • macOS users with OmniFocus who want to drive their task database in natural language
  • OmniFocus users who need an AI assistant to bulk-organize and reorganize tasks
  • Users comfortable granting macOS automation access and troubleshooting AppleEvent timeouts
  • 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
  • Windows or Linux users, since the server depends on OmniFocus on macOS
  • Users whose environment cannot grant macOS automation permissions
  • Users expecting official Omni Group support, as this is a third-party open-source project
  • 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 macOS Automation (AppleEvents) access to control OmniFocus
  • Reads and writes the local OmniFocus database through osascript
  • The shared daemon listens on a 0700-permission Unix domain socket under ~/.omnifocus-mcp/; access is enforced by the filesystem, with no network port and no token
  • 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
  • Once automation access is granted, the server can read and modify the local OmniFocus database, including removing tasks and projects; removals may warrant care.
  • Editing or removing completed past occurrences of repeating items cascades through the live repeat chain and is refused by default unless explicitly allowed.
  • If the shared daemon crashes or is killed, attached clients can be affected; newer versions reconnect and replay the initialize handshake.
  • Right after an upgrade two daemons may briefly coexist, with clients attached to the old one receiving an in-band upgrade notice in tool results.
  • Too many concurrent osascript calls can cause AppleEvent timeouts.
  • 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
