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.

run in your terminal
claude mcp add mcp-nbb -- uvx mcp-nbb
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "mcp-nbb": {
      "args": [
        "mcp-nbb"
      ],
      "command": "uvx"
    }
  }
}

[mcp_servers.mcp-nbb]
command = "uvx"
args = ["mcp-nbb"]

{
  "mcpServers": {
    "mcp-nbb": {
      "args": [
        "mcp-nbb"

  }
}

This one needs environment variables set before it will start: NBB_LOG_LEVEL (Log level: DEBUG, INFO, WARNING, ERROR), NBB_LOG_FORMAT (Log format: 'json' or 'console'), NBB_HTTP_CACHE_ENABLED (Enable the persistent HTTP disk cache). The author declared them in the registry entry; get the values from the project itself.

MCP Nbb — questions

Answers built from our own checks of this server.

Why is there no uptime for MCP Nbb?
MCP Nbb runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package mcp-nbb was installed 80 times last week.
How do I connect MCP Nbb?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls mcp-nbb straight from pypi; nothing to host, nothing to sign up for.
How many people use MCP Nbb?
The pypi package mcp-nbb was installed 80 times in the last week. Week over week that is -7%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is MCP Nbb open source?
Yes — it is published under the MIT licence, written in Python and 3 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
