| 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
| - Individuals or teams who prioritise privacy and offline operation and do not want data leaving the machine
- Users who share memory across multiple MCP clients such as Claude Code, Claude Desktop, Hermes Agent, OpenClaw, Cursor, Codex and Gemini CLI
- Scenarios that need encrypted storage, a hash-chained audit log and verifiable vault migration
- Users who want low-latency recall, a bundled embedding model and no extra LLM calls inside the memory layer
|
| 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 who need cloud multi-device sync or a hosted team memory service; moving between machines means locking the vault and copying the file
- Users who expect the server itself to run an LLM that extracts facts and decides what to remember; Compartment explicitly keeps no LLM inside and leaves that to the host model
- Users who cannot keep a passphrase safe or who need a recovery path if it is lost, since Compartment never generates a password, seed or recovery phrase
- Deployments that require network transports such as SSE or streamable-http; this server is stdio only and opens no ports
|
| 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
| - Read and write the vault file under the user's home directory, by default ~/.compartment/memory.vault, and its sibling settings file
- Access the session directory holding the unlock credential (configurable with COMPARTMENT_SESSION_DIR), which also carries the shared embedding process's Unix socket
- Optionally use the macOS keychain (compartment unlock --keychain is an explicit opt-in, and it survives reboots)
- Write or merge an mcpServers entry into each MCP client's own configuration file, taking a byte-exact backup first
- Install a PostToolUse hook for Claude Code that captures memory files the agent writes
- Serve a read-only dashboard on 127.0.0.1 behind a one-time random URL token
|
| 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
| - A leaked passphrase means the encrypted content can be decrypted; Compartment generates no recovery phrase and cannot recover a lost passphrase
- Enabling the memory_unlock tool places the passphrase in the model's context, which is why it is off by default
- If a 2FA keyfile is lost, for example a USB stick, the vault cannot be opened even with the passphrase
- `export --plaintext` writes the vault as unencrypted JSONL, so that file must be handled carefully
- Memory content can come from untrusted sources; recall wraps memories with a notice that they are stored data and content can be marked quarantined, but the host agent must still treat memory as data to limit prompt-injection risk
- The capture hook and client integration write into the user's own settings files, although the implementation backs up and merges rather than replacing
