The Letta MCP Server provides comprehensive tools for agent management, memory operations, and tool integration within the Letta system.
- Agent Management: Create, list, prompt, modify, delete, clone, and bulk delete agents with specific configurations
- Memory Management: Create, list, read, update, and attach memory blocks to agents
- Tool Management: List, attach (individually or in bulk), and upload tools for agents
- Additional Features: Manage models (LLM and embedding), archive passages, other MCP servers, and import/export agent configurations
- Deployment: Run locally with Node.js or Docker, configurable via
mcp_settings.json
Uses .env files for configuration, allowing storage of Letta API credentials and endpoints securely outside of the codebase.
Repository hosting for the Letta MCP server, enabling version control, contribution workflows, and distribution of the server code.
Provides package management for the Letta MCP server, managing dependencies and offering scripts for building and running the server.
Used as the implementation language for the Letta MCP server, with build scripts to compile TypeScript code before execution.
