Copilot ↔ Memory Journal MCP Bridge

Connect memory-journal-mcp to GitHub Copilot for cross-agent knowledge sharing. Two agents, one shared memory.

How It Works

IDE Agent (AntiGravity/Cursor)  ←→  memory-journal-mcp  ←→  Copilot (GitHub)
         reads reviews via API        shared memory         reads context via MCP

Pattern 1 — Learn from reviews: The IDE agent reads Copilot's PR review findings with get_copilot_reviews, creates copilot-finding journal entries, and suggests rule updates.

Pattern 2 — Pre-emptive checking: Before writing code, the IDE agent searches past copilot-finding entries and applies patterns proactively.

Pattern 3 — Context-aware reviews: Copilot uses memory-journal-mcp as an MCP server during PR review, gaining access to project history and architectural decisions.

Setup: Copilot → Memory Journal (MCP Server)

Local MCP (VS Code / Copilot Chat)

Add to your workspace .vscode/mcp.json:

{
  "servers": {
    "memory-journal": {
      "command": "npx",
      "args": ["-y", "memory-journal-mcp"],
      "env": {
        "DB_PATH": "./memory-journal.db",
        "GITHUB_TOKEN": "${env:GITHUB_TOKEN}",
        "PROJECT_REGISTRY": "{\"my-repo\":{\"path\":\".\",\"project_number\":1}}"
      }
    }
  }
}

Remote MCP (HTTP Transport)

For Copilot Code Review or remote agents, deploy in HTTP mode:

npx memory-journal-mcp --transport http --port 3100

Then configure as a remote MCP server in your GitHub Copilot settings.

Setup: IDE Agent → Copilot Reviews

Enable Copilot review data in the briefing by setting:

BRIEFING_COPILOT_REVIEWS=true

Or use the CLI flag:

--briefing-copilot

Then use get_copilot_reviews(pr_number) to fetch Copilot's findings for any PR.

Security Note

When connecting memory-journal-mcp to Copilot:

  • Use read-only OAuth scopes (e.g., a read-level scope) and follow the principle of least privilege if OAuth is enabled
  • The journal database may contain project decisions, architecture notes, and code patterns — share only what's appropriate
  • Copilot's access follows your GitHub repository permissions
