| Best for | - Users who want video preprocessing to stay local and only the chosen material to reach a cloud LLM
- Developers using MCP-capable coding agents such as Claude Code or Cursor who need video evidence
- Video analysis where scene-aware extraction beats fixed-interval sampling
| - 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 expecting a hosted server with no local ffmpeg install
- Enterprise procurement needing official Anthropic support or an SLA
- Users who just want a one-off answer about one clip and do not care about local processing or reproducibility
| - 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 | - Read video and subtitle files at any path you point it at on the local machine
- Network access via yt-dlp to fetch video URLs
- Write to the output directory (default crv-out) and the MCP analysis cache at ~/.cache/crv-mcp
- Maintain a local SQLite memory index at ~/.crv/memory.db (overridable with CRV_MEMORY_DB, disable with CRV_NO_MEMORY=1)
- Optional: read browser cookies to reach login-gated content in your own account
| - 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 | - Processing copyrighted or unauthorized content may violate the source site's terms; --cookies is meant for your own authorized access only
- Transcripts and the memory index persist speech and on-screen text on local disk, which matters on shared machines
- Whisper can invent captions on music-only or silent audio (installing the [fast] extra adds faster-whisper with Silero VAD to avoid this)
- Once you paste extracted frames or the transcript into a cloud LLM, that data is handled by that provider
- crv Pro is a paid add-on; the free edition lacks Pro features such as camera motion and voice emotion
| - 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
