01 · Install Replen

before you install - you'll need

Set DIGEST_BASE_URL, DIGEST_TOKEN, DEPLOY_HOST before connecting.

Claude Code

claude mcp add replenhq-replen -- npx -y @replen/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "replenhq-replen": {
      "command": "npx",
      "args": [
        "-y",
        "@replen/mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-07-09 - young repo, little track record yet

license Apache-2.0 - declared in the repository

npm package @replen/mcp - the @replen scope differs from the repo owner (replenhq); confirm it's the project's official package

registry namespace io.github.replenhq is GitHub-verified and matches the repo owner
