Kongyo MCP DevMCP Server

Provides programmatic inspection of MCP servers via tools, resources, and prompts for testing and development.

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "kongyo2-mcpdevmcp": {
      "command": "npx",
      "args": [
        "-y",
        "@kongyo2/mcpdevmcp"
      ]
    }
  }
}

You can use this MCP server to programmatically inspect and validate other MCP servers from your own environment. It wraps the Inspector CLI capabilities so an LLM agent or automation can list tools, read resources, and test prompts on target MCP servers through flexible transports like local commands or remote URLs.

How to use

You connect your MCP client to the mcpdev MCP server to perform inspections from your own environment. The server supports two transport methods: stdio for local command execution and http/sse for remote MCP URLs. You can run a sequence of actions to explore a target MCP server: list all available tools, execute a specific tool, enumerate resources, read a resource, list prompts, and retrieve a prompt template. Use these steps to validate behavior, compare results across targets, and verify prompt responses without leaving your development workflow.

To start, configure your MCP client to include the mcpdev server. The quick start configuration shows how to add the server so your client can invoke it locally with a single command. Then you can run inspector-like commands against a target to confirm it exposes the expected tools, resources, and prompts.

How to install

Prerequisites: ensure you have Node.js and npm installed on your system. You should be able to run npm commands from your shell.

Install dependencies for the MCP development server and build the project.

npm install
npm run build

Configuration and quick start

Add the MCP server to your MCP client configuration so you can invoke it from your environment.

{
  "mcpServers": {
    "mcpdev": {
      "command": "npx",
      "args": ["-y", "@kongyo2/mcpdevmcp"]
    }
  }
}

Notes and practical usage

This MCP server enables programmatic inspection of target MCP servers. It supports both local execution and remote connections, letting you validate tools, resources, and prompts directly from your development environment. When you write automation or agents, you can rely on the same capabilities you would manually invoke through the Inspector.
