What it does
MemPalace is a memory system for AI agents that runs on the user's own machine. It keeps conversation history as verbatim text and finds it again with semantic search, using ChromaDB by default with a pluggable backend, plus a knowledge graph. Its MCP server offers a large set of tools for reading and writing the store, knowledge-graph work, navigation, agent diaries and coordination between agents. The core search needs no API key; a language model is only needed for optional reranking. It installs with pip, uv or pipx, or runs as a Docker image over stdio, and the README covers Claude Code, Gemini CLI and Antigravity, with auto-save hooks for Claude Code, Codex CLI and Cursor.
