Best for
  • Individual learners already using Anki and AnkiConnect.
  • Users who want AI-guided review, explanations, and dynamic card creation.
  • Users connecting local Anki to Claude Desktop, Cursor, Cline, or Zed.
  • 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
  • Users without the Anki desktop application or AnkiConnect.
  • Organizations requiring official Anki support or an official integration.
  • Remote users seeking only review workflows; GUI tools are intended for editing and creation, not review sessions.
  • 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
  • Requires access to the configured AnkiConnect URL, which defaults to local http://localhost:8765.
  • Write operations can create, modify, move, and delete Anki content; deletion tools require explicit confirmation.
  • Media imports may read specified file paths or URLs, subject to media security settings.
  • If AnkiWeb sync is enabled, the Anki application synchronizes directly with AnkiWeb.
  • 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
  • The project is explicitly in beta, and APIs and features may change.
  • Deleting notes permanently removes associated cards; clearing tags, deleting media, and removing fields can also cause data loss.
  • updateNoteFields may silently fail while the note is being viewed in Anki's browser.
  • ngrok mode is unauthenticated, so anyone with the URL may reach Anki; the managed Tunnel requires login authentication.
  • Remote HTTP exposure requires correct ALLOWED_HOSTS configuration; misconfiguration can cause rejected requests or broader exposure.
  • 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
