Best for
  • Researchers, students, and academics who want to integrate their Zotero library with AI assistants.
  • Users who need quick retrieval, summarization, and annotation of papers.
  • Those looking for semantic search to discover related research.
  • Users who want to automate library management tasks like bulk adding and deduplication.
  • 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 who don't need AI integration and just want a terminal interface (use zotero-cli).
  • Users who don't use Zotero.
  • Users who require fully offline operation without local Zotero installation (web API mode still needs internet).
  • 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
  • Reads local Zotero database files (default path).
  • Writes to Zotero via Web API in hybrid mode (add, update, delete items).
  • Accesses Zotero attachment files (e.g., PDFs) to extract full text and annotations.
  • When semantic search is enabled, calls embedding model APIs (e.g., OpenAI, Gemini) and stores index data.
  • When scite tools are enabled, calls scite.ai public API.
  • 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
  • AI assistants may misinterpret or misread library data; verify important information manually.
  • Web API mode requires a Zotero API key; if compromised, unauthorized access to your library is possible.
  • Semantic search indexes may contain sensitive content; protect stored embeddings.
  • Enabled optional tool groups (e.g., scite) trigger external network requests.
  • 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
