An MCP server for LETHE, a context management system for long-running LLM agents that archives large tool outputs externally and recalls them on demand to reduce context growth and token usage. It exposes archive, recall, and status operations for Claude Code and Codex.

From the registry: Context GC for LLM agents: offload large tool outputs and recall them to save tokens.

Install in your client

Paste into the AI you're chatting with — it will figure out the rest

Please install the `lethe` MCP server into my current AI client (that's you).

Required prerequisites (do these first if not already done):
- **Install Python package with MCP extras** — Install the Lethe package and its MCP server entrypoint. Run: `pip install "lethe-llm-context[mcp]"` (https://pypi.org/project/lethe-llm-context/'}],)

Canonical MCP server config (stdio transport):
- command: `lethe-mcp`
- args: []

Note: README shows a stdio MCP server launched via the `lethe-mcp` command after installing the Python package with MCP extras. No MCP-specific environment variables are documented. `ANTHROPIC_API_KEY` appears only for a separate real Claude demo, not for running the MCP server itself.

Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.
