# PMB AI (MCP server)

> PMB AI is an MCP server that adds search and knowledge tools to AI assistants such as Claude Desktop, Claude Code and Cursor. Local-first persistent memory for AI coding agents. It has 281 GitHub stars, is released under the Apache-2.0 license and runs locally with uvx pmb-ai.

Local-first memory, visualized. 3,800+ entities and 41,000+ connections, captured automatically as you work. Your AI agent forgets everything between sessions. So you re-explain the same decisions, lessons and constraints over and over. PMB remembers them in one local workspace and feeds them back through MCP - no cloud, no API keys, no LLM call on the read path. And it tells you when memory is actually helping, instead of claiming "+X%".
