What the code does

We read the source, 21 h ago · rules 3dff92dd89df

In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Builds a database query by concatenation .github/workflows/release.yml:78
      - name: Generate release notes and update CHANGELOG.md
        env:
          GH_TOKEN: ${{ github.token }}

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

Nothing serious here today

Today is the operative word: we check ReviewGuard every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add review-guard -- npx -y @eclipsesource/review-guard-mcp
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "review-guard": {
      "args": [
        "-y",
        "@eclipsesource/review-guard-mcp"
      ],
      "command": "npx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.review-guard]
command = "npx"
args = ["-y", "@eclipsesource/review-guard-mcp"]
.cursor/mcp.json
{
  "mcpServers": {
    "review-guard": {
      "args": [
        "-y",
        "@eclipsesource/review-guard-mcp"
      ],
      "command": "npx"
    }
  }
}
.vscode/mcp.json
{
  "mcpServers": {
    "review-guard": {
      "args": [
        "-y",
        "@eclipsesource/review-guard-mcp"
      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: GITHUB_TOKEN (GitHub token with pull request read and write access. Can be left unset if the GitHub CLI is authenticated, because the server then falls back to gh auth token.). The author declared them in the registry entry; get the values from the project itself.

ReviewGuard — questions

Answers built from our own checks of this server.

Why is there no uptime for ReviewGuard?
ReviewGuard runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @eclipsesource/review-guard-mcp was installed 70 times last week.
How do I connect ReviewGuard?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @eclipsesource/review-guard-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use ReviewGuard?
The npm package @eclipsesource/review-guard-mcp was installed 70 times in the last week. Week over week that is +76%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is ReviewGuard open source?
Yes — it is published under the MIT licence, written in TypeScript and 4 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
