    "rss-reader": {
      "command": "npx",
      "args": [
        "-y",
        "rss-reader-mcp"
      ]
    }
  }
}

⚙️ Transport & Environment Variables

This server supports two transport modes:

• stdio (default): Communicates via standard input/output. Suitable for clients that run a local process, such as Claude Desktop.
• httpStream: Communicates over HTTP streaming. Suitable for clients that support HTTP(S) transport or for containerized deployments.

Available environment variables:

• TRANSPORT: Select the transport mode, either stdio (default) or httpStream.
• PORT: When TRANSPORT=httpStream, the listening port (default 8081).
• MCP_SERVER_HOST: When TRANSPORT=httpStream, the listening address (default localhost). In Docker, set this to 0.0.0.0 to expose the port externally.

How to switch transport modes:

• Using stdio (no extra setup, default):
• Works with Claude Desktop via the command + args configuration (see example above).
• Using httpStream:
• Set the environment variable TRANSPORT=httpStream and specify PORT (defaults to 8081 if not set).
• When running in a container, also set MCP_SERVER_HOST=0.0.0.0 and map the port.
• The Dockerfile in this repository already includes related environment variable settings.

Docker Deployment

You can also run this MCP server in a Docker container. First, build the image in the project root:

docker build -t rss-reader-mcp .

Using CherryStudio as an example, the following configuration shows how to run this server over HTTP:

{
  "mcpServers": {
    "rss-reader-mcp": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-p",
        "8081:8081",
        "-e",
        "PORT=8081",
        "rss-reader-mcp"
      ]
    }
  }
}
