Verified Safeby akkytech0617
Overview
Provides a Model Context Protocol (MCP) server to connect AI agents like Factory Droid, Claude Code, and Cursor to Letta Cloud's stateful memory system for persistent memory, agent interaction, and archival storage.
Installation
node dist/index.jsEnvironment Variables
- LETTA_API_KEY
- LETTA_DEFAULT_AGENT_ID
Security Notes
The server uses `process.env` for API keys, preventing hardcoding. Input validation is rigorously handled by Zod schemas for all tool arguments. Communication with Letta Cloud uses an official SDK, presumably over HTTPS. The server primarily communicates via standard I/O (stdio) as an MCP server, not exposing network ports directly. While `@modelcontextprotocol/sdk` (a dependency) can involve `cross-spawn` for running external processes, this specific server acts as the *target* for such commands from an MCP client, not an initiator of arbitrary commands based on user input. The main security considerations would be the secure handling of `LETTA_API_KEY` and the integrity of the MCP client connecting to it.
