Installation

Using uv (recommended)

When using uv no specific installation is needed. We will use uvx to directly run mcp-server-http-request.

Using PIP

Alternatively you can install mcp-server-http-request via pip:

pip install mcp-server-http-request

After installation, you can run it as a script using:

python -m mcp_server_http_request

Configuration

Configure for Claude.app

Add to your Claude settings:

{
  "mcpServers": {
    "http-request": {
      "command": "uvx",
      "args": ["mcp-server-http-request"]
    }
  }
}

{
  "mcpServers": {
    "http-request": {
      "command": "python",
      "args": ["-m", "mcp_server_http_request"]
    }
  }
}

Customization - User-agent

By default, the server uses the user-agent:

ModelContextProtocol/1.0 (HTTP-Request; +https://github.com/modelcontextprotocol/servers)

This can be customized by adding the argument --user-agent=YourUserAgent to the args list in the configuration.

Customization - Proxy

The server can be configured to use a proxy by using the --proxy-url argument.
