What the code does

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

  const probe = spawnSync(WINDOWS ? "where" : "which", WINDOWS ? [command] : ["-a", command], {

    subprocess.run(["ffmpeg", "-y", "-loglevel", "error", *args], check=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.

claude mcp add rendercheck -- uvx rendercheck

{
  "mcpServers": {
    "rendercheck": {
      "args": [
        "rendercheck"
      ],
      "command": "uvx"
    }
  }
}

[mcp_servers.rendercheck]
command = "uvx"
args = ["rendercheck"]

{
  "mcpServers": {
    "rendercheck": {
      "args": [
        "rendercheck"
      ],
      "command": "uvx"
    }
  }
}

This one needs environment variables set before it will start: ANTHROPIC_API_KEY (Only for the optional `looks ok` vision check. Every other check is deterministic and needs no key.). The author declared them in the registry entry; get the values from the project itself.
