B4n1Web

B4n1Web runs locally from a Node.js package published to the npm registry: b4n1-web version 0.12.1. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Node.js; clients usually start it with npx — the usual command is npx -y b4n1-web@0.12.1.

B4n1Web runs locally from a Python package published to PyPI: b4n1-web version 0.12.1. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Python; clients usually start it with uvx (from uv) or after pip install — the usual command is uvx b4n1-web.

B4n1Web runs locally from a .NET package published to NuGet: B4n1Web version 0.12.1. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs the .NET SDK; run as a .NET tool.

In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):

{
  "mcpServers": {
    "b4n1web": {
      "command": "npx",
      "args": [
        "-y",
        "b4n1-web@0.12.1"
      ]
    }
  }
}
