Copilot Memory MCP

by auspham

Copilot Memory MCP

Give GitHub Copilot CLI (or any MCP-compatible agent) persistent memory across sessions.

Without this, Copilot CLI starts every session as a blank slate. With this MCP server running, it can save and recall knowledge — learning from experience just like you do.

What It Does

  • Saves memories — fixes, preferences, lessons, code snippets, project context

  • Recalls memories — full-text search across everything it's ever learned

  • Categorizes knowledge — preference, lesson, fix, context, convention, environment, snippet

  • Tracks usage — knows which memories are accessed most often

  • Persists in SQLite — lightweight, no external services, survives restarts

Tools Provided

Memory Tools

Tool

Description

save_memory

Store a new piece of knowledge with category and tags

recall_memories

Search or browse past memories (full-text search)

update_memory

Update an existing memory when things change

forget_memory

Delete a memory that's no longer relevant

memory_stats

See what's in the knowledge base

Monitoring Tools

These solve the "Copilot stops and asks should I continue?" problem. Each tool runs a long-running polling loop internally, so Copilot uses one tool call instead of burning through its iteration limit.

Tool

Description

monitor_command

Run a command repeatedly, collect output, stop on pattern/change/exit code

watch_file

Watch a file for changes or a regex pattern match

poll_url

Poll a URL until expected HTTP status or body pattern

run_long_command

Run a single long command, stream output, stop on pattern

Quick Start

1. Clone and install

git clone <this-repo> ~/projects/copilot-memory-mcp
cd ~/projects/copilot-memory-mcp
uv sync

Or if you don't have uv:

cd ~/projects/copilot-memory-mcp
python3 -m venv .venv
source .venv/bin/activate
pip install "mcp[cli]>=1.20"

2. Test it works

# Quick test — should print tool list
uv run mcp dev server.py

This opens the MCP Inspector in your browser where you can test the tools interactively.

3. Add to GitHub Copilot CLI

Edit (or create) your Copilot MCP config file:

Linux/macOS:

mkdir -p ~/.config/github-copilot
nano ~/.config/github-copilot/mcp.json

Windows:

%LOCALAPPDATA%\github-copilot\mcp.json

Add this content:

{
  "mcpServers": {
    "copilot-memory": {
      "command": "uv",
      "args": ["run", "--directory", "/FULL/PATH/TO/copilot-memory-mcp", "server.py"],
      "env": {}
    }
  }
}

Important: Replace /FULL/PATH/TO/copilot-memory-mcp with the actual absolute path.

If you don't have uv, use the venv Python directly:

{
  "mcpServers": {
    "copilot-memory": {
      "command": "/FULL/PATH/TO/copilot-memory-mcp/.venv/bin/python",
      "args": ["/FULL/PATH/TO/copilot-memory-mcp/server.py"],
      "env": {}
    }
  }
}

Copy the included template to your global Copilot instructions so it knows to USE the memory:

mkdir -p ~/.github
cp copilot-instructions-template.md ~/.github/copilot-instructions.md

Or for a specific repo:

cp copilot-instructions-template.md YOUR_REPO/.github/copilot-instructions.md

5. Use it

Start Copilot CLI normally. It will now have access to memory tools. The instructions file tells it to check memory at session start and save important learnings.

$ copilot

> Hey, can you check what you remember about this project?

# Copilot calls recall_memories() automatically
# and loads any past context

How the Learning Loop Works

Session 1:
  You: "Always use pytest, never unittest"
  Copilot saves: {category: "preference", content: "User prefers pytest over unittest"}

Session 2:
  Copilot starts → calls recall_memories() → loads preference
  Copilot: "I'll set up the tests with pytest as you prefer."
  You debug a tricky async issue together
  Copilot saves: {category: "fix", content: "asyncio.gather swallows exceptions — use return_exceptions=True"}

Session 3:
  Copilot starts → recalls all memories → knows your preferences AND past fixes
  You hit a similar async bug
  Copilot: "This looks like the asyncio.gather issue we fixed before — need return_exceptions=True"

Each session makes the next one smarter.

Monitoring — No More "Should I Continue?"

The monitoring tools solve Copilot CLI's biggest limitation: it stops and asks for confirmation during long-running tasks. These tools do the looping internally.

Example: Watch a Kubernetes deployment

You: "Deploy the new version and monitor until all pods are running"

Copilot runs:
  monitor_command(
    command="kubectl get pods -l app=myapp",
    interval_seconds=10,
    timeout_seconds=300,
    stop_pattern="1/1.*Running"
  )

→ Tool polls every 10s for up to 5 minutes
→ Returns all snapshots when pods are Running
→ ONE tool call, no iteration limit hit

Example: Watch a build log

You: "Start the build and tell me when it's done"

Copilot runs:
  run_long_command(
    command="npm run build 2>&1",
    timeout_seconds=300,
    stop_pattern="Build complete|ERROR"
  )

→ Captures the entire build output
→ Returns immediately when it sees success or failure

Example: Wait for a service to come up

You: "Deploy and let me know when the health check passes"

Copilot runs:
  poll_url(
    url="http://localhost:8080/health",
    expected_status=200,
    expected_body_pattern="healthy",
    interval_seconds=5,
    timeout_seconds=120
  )

→ Polls every 5s until 200 + "healthy" in body
→ Reports back with timing and response details

Max monitoring duration

Default max is 1 hour (3600 seconds). Override with env var:

{
  "mcpServers": {
    "copilot-memory": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/copilot-memory-mcp", "server.py"],
      "env": {
        "COPILOT_MEMORY_MAX_MONITOR": "7200"
      }
    }
  }
}

Configuration

Custom database location

By default, memories are stored in ~/.copilot-memory/memory.db. Override with:

{
  "mcpServers": {
    "copilot-memory": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/copilot-memory-mcp", "server.py"],
      "env": {
        "COPILOT_MEMORY_DB": "/custom/path/to/memory.db"
      }
    }
  }
}

SSE transport (for HTTP-based clients)

uv run server.py --transport sse

This starts an HTTP server (default port 8000) for clients that prefer SSE over stdio.

Works With Other Agents Too

This isn't Copilot-specific. Any MCP client can use it:

  • Claude Code — add to .mcp.json in your project

  • Cline (VS Code) — add to MCP server settings

  • Hermes Agent — add to config.yaml under mcp.servers

  • Cursor — add to MCP configuration

  • Any MCP-compatible tool

Claude Code example (.mcp.json in project root):

{
  "mcpServers": {
    "memory": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/copilot-memory-mcp", "server.py"]
    }
  }
}
