GitMem — Institutional memory for AI coding agents

npm version npm downloads MIT License Build Node.js >= 18

Documentation · npm · Getting Started · Tool Reference


GitMem is an MCP server that gives your AI coding agent persistent memory across sessions. It remembers mistakes (scars), successes (wins), and decisions — so your agent learns from experience instead of starting from scratch every time.

What's MCP? Model Context Protocol is how AI coding tools connect to external capabilities. GitMem is an MCP server — install it once and your agent gains persistent memory.

Works with Claude Code, Cursor, VS Code (Copilot), Windsurf, and any MCP-compatible client.

Quick Start

npx gitmem-mcp init

One command. The wizard auto-detects your IDE and sets up everything:

  • .gitmem/ directory with starter scars
  • MCP server config (.mcp.json, .vscode/mcp.json, .cursor/mcp.json, etc.)
  • Instructions file (CLAUDE.md, .cursorrules, .windsurfrules, .github/copilot-instructions.md)
  • Lifecycle hooks (where supported)
  • .gitignore updated

Already have existing config? The wizard merges without destroying anything. Re-running is safe.

npx gitmem-mcp init --yes                # Non-interactive
npx gitmem-mcp init --dry-run            # Preview changes
npx gitmem-mcp init --client vscode      # Force specific client

How It Works

recall  -->  work  -->  learn  -->  close  -->  recall  -->  ...
  1. Recall — Before acting, the agent checks memory for relevant lessons from past sessions
  2. Work — The agent does the task, applying past lessons automatically
  3. Learn — Mistakes become scars, successes become wins, strategies become patterns
  4. Close — Session reflection persists context for next time

Every scar includes counter-arguments — reasons why someone might reasonably ignore it. This prevents memory from becoming a pile of rigid rules.

What Gets Remembered

Type Purpose Example
Scars Mistakes to avoid "Always validate UUID format before DB lookup"
Wins Approaches that worked "Parallel agent spawning cut review time by 60%"
Patterns Reusable strategies "5-tier test pyramid for MCP servers"
Decisions Architectural choices with rationale "Chose JWT over session cookies for stateless auth"
Threads Unfinished work that carries across sessions "Rate limiting still needs implementation"

Key Features

  • Automatic Recall — Scars surface before the agent takes similar actions
  • Session Continuity — Context, threads, and rapport carry across sessions
  • Closing Ceremony — Structured reflection captures what broke, what worked, and what to do differently
  • 20+ MCP Tools — Full toolkit for memory management, search, threads, and multi-agent coordination
  • Zero Confignpx gitmem-mcp init and you're running
  • Non-Destructive — Merges with your existing .mcp.json, CLAUDE.md, and hooks

Supported Clients

Client Setup Hooks
Claude Code npx gitmem-mcp init Full (session, recall, credential guard)
Cursor npx gitmem-mcp init --client cursor Partial (session, recall)
VS Code (Copilot) npx gitmem-mcp init --client vscode Instructions-based
Windsurf npx gitmem-mcp init --client windsurf Instructions-based
Claude Desktop Add to claude_desktop_config.json Manual
Any MCP client npx gitmem-mcp init --client generic Instructions-based

The wizard auto-detects your IDE. Use --client to override.

Manual MCP configuration

Add this to your MCP client's config file:

{
  "mcpServers": {
    "gitmem": {
      "command": "npx",
      "args": ["-y", "gitmem-mcp"]
    }
  }
}
Client Config file
Claude Code .mcp.json
Cursor .cursor/mcp.json
VS Code .vscode/mcp.json
Windsurf ~/.codeium/windsurf/mcp_config.json

CLI Commands

Command Description
npx gitmem-mcp init Interactive setup wizard (auto-detects IDE)
npx gitmem-mcp init --client <name> Setup for specific client (claude, cursor, vscode, windsurf, generic)
npx gitmem-mcp init --yes Non-interactive setup
npx gitmem-mcp init --dry-run Preview changes
npx gitmem-mcp uninstall Clean removal (preserves .gitmem/ data)
npx gitmem-mcp uninstall --all Full removal including data
npx gitmem-mcp check Diagnostic health check

Pro Tier — Coming Soon

What you get Why your agent cares
Semantic search Recall returns the right scars, not keyword noise
Session analytics Spot patterns in what keeps going wrong
Sub-agent briefing Hand institutional context to sub-agents automatically
Cloud persistence Memory survives machine changes, shareable across team
A/B testing analytics Measure which scar phrasings actually change agent behavior (free tier includes GITMEM_NUDGE_VARIANT for manual testing)

The free tier gives you everything for solo projects. Pro makes recall smarter and memory portable.

GitMem + MEMORY.md

Your AI agent likely has its own memory file (MEMORY.md, .cursorrules, etc.). Here's how they work together:

MEMORY.md GitMem
Loaded Every turn (system prompt) On-demand (tool calls)
Best for Preferences, shortcuts, quick reference Earned lessons, unfinished work, decisions
Updates Agent writes directly Session lifecycle (close ceremony)
Example "User prefers terse output" "Always validate UUID before DB lookup"

Tip: Include .gitmem/agent-briefing.md in your MEMORY.md for a lightweight bridge between the two systems.

Privacy & Data

  • Local-first — All data stored in .gitmem/ on your machine by default
  • No telemetry — GitMem does not collect usage data or phone home
  • Cloud opt-in — Pro tier Supabase backend requires explicit configuration via environment variables
  • Your data — Sessions, scars, and decisions belong to you. Delete .gitmem/ to remove everything

Development

git clone https://github.com/gitmem-dev/gitmem.git
cd gitmem
npm install
npm run build
npm test
