Usage

MCP Server Configuration

{
    "mcpServers": {
        "mcp-server-requests": {
            "command": "python",
            "args": [
                "-m",
                "mcp_server_requests"
            ]
        }
    }
}

Command Line

0. Start MCP Server

Start the MCP server directly:

python -m mcp_server_requests

Options

--user-agent TEXT: Specify custom User-Agent string
--random-user-agent [browser=xxx;os=xxx]: Use randomly generated User-Agent
--force-user-agent: Force using command line specified User-Agent, ignoring LLM provided UA
--list-os-and-browser: List available browsers and OS for random User-Agent generation

Option Details

--user-agent and --random-user-agent are mutually exclusive and cannot be used together
User-Agent setup methods:
- Custom string: --user-agent "Mozilla/5.0 (...)"
- Fully random: --random-user-agent
- Conditional random generation:
  - Specify browser type: --random-user-agent browser=chrome
  - Specify OS: --random-user-agent os=windows
  - Both browser and OS: --random-user-agent browser=chrome;os=windows
  - Note: Browser and OS parameters are case insensitive
Use --list-os-and-browser to view available browsers and OS for --random-user-agent.
--force-user-agent controls User-Agent priority:
- When enabled: Prioritize command line specified User-Agent (via --user-agent or --random-user-agent), ignoring LLM provided UA
- When disabled:
  - If LLM provides User-Agent, use that
  - Otherwise use command line specified User-Agent
