Introducing MCPHub.nvim: AI Integration for NeoVim

MCPHub.nvim is a powerful plugin that lets you connect and manage multiple MCP servers within NeoVim. This bridges the gap between code editors and the latest AI-powered development tools, allowing you to automate code generation, refactoring, and more—right from your editor.

How MCPHub.nvim Works

MCPHub.nvim uses a client-server architecture:

• NeoVim Client: Interacts with the mcp-hub server.
• mcp-hub (Express server): Orchestrates MCP servers and provides a REST API interface.
• MCP Servers: Run specialized AI tools (codegen, task managers, etc.).

This setup ensures unified management, real-time monitoring, and resource optimization—even when collaborating across multiple projects or team members.

When configured, MCPHub.nvim launches the mcp-hub server with your settings and exposes API endpoints for managing all MCP servers and tools.

Why MCPHub.nvim Is a Game-Changer

• Centralized AI Tool Control: Start, stop, and monitor all MCP servers from one place.
• Seamless Model Collaboration: Combine tools like Claude, GPT, or custom models in a single workflow.
• Efficient Resource Management: Start/stop servers as needed to optimize memory and token usage.
• Chat Plugin Integration: Effortlessly connect with plugins like CodeCompanion for interactive AI coding.

Step-by-Step: Installing and Setting Up MCPHub.nvim

System Requirements

Before starting, ensure your environment meets these:

Tip: Install UVX (Universal Version Executor) for easy server management:

npm install -g uvx

Installing MCPHub.nvim with lazy.nvim

Add this to your NeoVim plugin configuration:

{
    "ravitemer/mcphub.nvim",
    dependencies = {
        "nvim-lua/plenary.nvim",  -- For async support
    },
    build = "npm install -g mcp-hub@latest",  -- Core MCP Hub server
    config = function()
        require("mcphub").setup({
            port = 3000,  -- Hub port
            config = vim.fn.expand("~/.config/nvim/mcpservers.json"),  -- Absolute config path
            log = {
                level = vim.log.levels.WARN,
                to_file = true,  -- Logs at ~/.local/state/nvim/mcphub.log
            },
            on_ready = function()
                vim.notify("MCP Hub is online!")
            end
        })
    end
}

After installation:

• Restart NeoVim.
• Run :checkhealth mcphub to verify.
• Confirm server status:

  curl http://localhost:3000/api/status
  

Configuring MCP Servers

Create your config file at ~/.config/nvim/mcpservers.json:

{
  "mcpServers": {
    "codegen": {
      "command": "uvx",
      "args": ["mcp-server-codegen"],
      "env": {
        "OPENAI_KEY": "${ENV_YOUR_OPENAI_KEY}"
      }
    },
    "todoist": {
      "command": "npx",
      "args": ["-y", "@abhiz123/todoist-mcp-server"],
      "disabled": true,
      "env": {
        "TODOIST_API_TOKEN": "your_token_here"
      }
    }
  }
}

Options:

• disabled: Start manually (:MCPHubStart <name>)
• env: Set API keys securely
• autostart: Prevent heavy servers from auto-starting

MCPHub.nvim: First-Time Usage Guide

• Open MCPHub UI:
  :MCPHub
• In the interface:
  • S: Start/stop servers
  • T: Enable/disable tools
  • L: View real-time logs
• Test a server:

  :lua require("mcphub").get_hub_instance():call_tool("codegen", "ping", {}, { return_text = true })
  

• Reference all commands:
  :help mcphub

Integrating MCPHub.nvim with Chat Plugins
