GitMem is an MCP server that gives your AI coding agent persistent learning memory across agent 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 Config — npx 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.

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 activate <key>	Activate Pro tier (auto-applies schema)
npx gitmem-mcp deactivate	Remove Pro credentials, free device slot
npx gitmem-mcp setup	Output schema SQL (for manual Supabase setup)
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

Self-hosted on your own Supabase. You bring the infrastructure, gitmem sets it up.

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

Quick start

npx supabase login                                          # one time
export SUPABASE_URL="https://yourproject.supabase.co"
export SUPABASE_SERVICE_ROLE_KEY="eyJ..."
export OPENROUTER_API_KEY="sk-or-v1-..."
npx gitmem-mcp activate <your-license-key>

The activate command creates all tables, views, RPC functions, and indexes automatically. No manual SQL needed.

See docs/pro-setup-guide.md for the full guide.

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
