Lethe

Overview

Lethe is a Model Context Protocol (MCP) server: Context GC for LLM agents: offload large tool outputs and recall them to save tokens. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.

It runs locally: the Python package lethe-llm-context (via uvx) speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.6.2, published under the Unlicense license, with source at JesusGarcia9009/lethe-engineering on GitHub.

You'll find Lethe in the AI & Agents category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
