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.

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 rubric-protocol -- npx -y @rubric-protocol/mcp-server

{
  "mcpServers": {
    "rubric-protocol": {
      "args": [
        "-y",
        "@rubric-protocol/mcp-server"
      ],
      "command": "npx"
    }
  }
}

[mcp_servers.rubric-protocol]
command = "npx"
args = ["-y", "@rubric-protocol/mcp-server"]

{
  "mcpServers": {
    "rubric-protocol": {
      "args": [
        "-y",
        "@rubric-protocol/mcp-server"
      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: RUBRIC_API_KEY (Rubric API key for Hedera mainnet anchoring. Optional — omit for free local PQ-signed attestation.). The author declared them in the registry entry; get the values from the project itself.
