Overview

💡 Self-Contained Architecture: The VS Code extension includes the MCP server pre-packaged. You don't need Python, external Node.js installations, or complex environment setups. Just install and go.

Installation

Option 1 — VS Code Extension (Recommended)

Install OpenGrok MCP from the VS Code Marketplace, or search "OpenGrok" in the Extensions panel.

The extension provides a visual configuration UI and manages the MCP server process automatically.

Option 2 — npm / npx

Global install:

npm install -g opengrok-mcp-server
opengrok-mcp setup      # interactive wizard: URL, credentials, MCP client registration

Or run without installing:

npx opengrok-mcp-server setup

The wizard stores credentials securely in the OS keychain (macOS Keychain, Windows Credential Manager, Linux libsecret) with an encrypted file fallback for headless Linux.

Configuration Guide

Provide Connection Details:
- After installation, the Settings panel will launch.
- Input your OpenGrok endpoint, username, and password. Hit Save Settings. (Credentials are locked in your native OS keychain).
- The plugin verifies the connection instantly. On your first run, VS Code will ask you to Reload the Window to register the MCP tools.
- (Need to change this later? Use the OpenGrok: Manage Configuration command or click the gear icon in the status bar).
Activate the MCP Source in Copilot:
- Launch the GitHub Copilot Chat window. Ensure you're using Agent mode.
- Click the paperclip/tools icon (🔧) in the prompt box.
- (If an Update Tools button appears, click it).
- Locate OpenGrok in the list, check the box, and confirm.

⚠️ Note that VS Code manages tool authorizations per workspace. If you open a different repository, you may need to re-check the OpenGrok box in Copilot.
