MCP server for AI memory management using Letta - Standard MCP format
The publisher's own server: Memory.fit
Overview
Local MCP server that connects an assistant to Letta for AI memory management, storing and associating memories per user.
- What you can do
- Connect an assistant to Letta for AI memory management in the standard MCP format.
- Store and associate memories with a specific user identifier.
- No individual tools are documented in the supplied listing, so exact operations are not described.
- When to use it
- Use when you want an assistant to keep persistent memories through Letta rather than within a single conversation, especially for per-user memory across sessions.
- Requirements
- Runs as a local process on the user's machine (desktop only, not web-executable), installed from the npm package @letta-ai/memory-mcp over stdio. Requires a Letta API key in LETTA_API_KEY and a user identifier in LETTA_USER_ID.
Installation
In SourceWeft
- Open Memory Mcp in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
