概览

What is PMB?

PMB (Personal Memory Brain) is a local-first persistent memory layer for AI coding agents over the Model Context Protocol. It provides Claude Code, Cursor, Codex, and other MCP-aware agents with a shared, durable memory of project decisions, lessons, facts, and goals that persists across sessions, stored entirely in a single SQLite file on your machine.

How to use PMB?

Install the package via pip (pip install pmb-ai), then connect it to your agent with a command like pmb connect claude-code. PMB works out of the box with Claude Code, Cursor, Codex, Windsurf, Zed, VS Code, and other MCP-compatible tools.

Key features of PMB

100% local — no cloud, no API keys, no telemetry
Hybrid retrieval using BM25, vector search, and entity graph
Achieves 94.5% evidence-recall@10 on the LoCoMo benchmark
Persistent memory across all coding sessions
Compatible with multiple MCP-aware agents

Use cases of PMB

Retaining project decisions and rationale between coding sessions
Storing lessons learned and domain facts for consistent agent behavior
Enabling multiple AI agents to share and update the same project memory
Building a durable, searchable knowledge base for long-running development workflows

FAQ from PMB

Where is my data stored?

All memory is kept in a single SQLite file on your local machine. No data is sent to the cloud or any third party.

What agents does PMB work with?

PMB is designed for any MCP-aware agent, including Claude Code, Cursor, Codex, Windsurf, Zed, and VS Code.

Do I need an API key or internet connection?

No. PMB requires no API keys, no cloud services, and no internet connectivity. It is entirely local.

How do I install PMB?

Install the Python package with pip install pmb-ai, then run pmb connect <agent-name> (e.g., pmb connect claude-code) to link it to your agent.

What license is PMB released under?

PMB is released under the Apache-2.0 license.
