mcp-project-helper

A lightweight, extensible MCP (Model Context Protocol) server for running prompt-based tools and file utilities. Designed for easy integration, testing, and extension with custom prompts.

Features

Prompt-based tools: Easily add new tools by writing simple JSON prompt files.
File utilities: Includes tools for reading, writing, moving, and deleting files and directories.
Custom prompts: Place your own prompt definitions in the custom_prompts/ directory.
Multiple transports: Supports STDIO, SSE, and HTTP for flexible integration.
Extensive tests: Includes a test script to verify all tool endpoints.

Getting Started

HTTP:

./mcp-project-helper -transport http -port 8080

Run Tests

./test.sh

🔌 Integration

VS Code

go install github.com/ad/mcp-project-helper@latest

Добавьте в settings.json:

{
  "mcp": {
    "servers": {
      "helper": {
        "type": "stdio",
        "command": "/absolute/path/to/project-helper",
        "args": ["-transport", "stdio"]
      }
    }
  }
}

Docker (VS Code)

{
  "mcp": {
    "servers": {
      "helper": {
        "type": "stdio",
        "command": "docker",
        "args": [
          "run", "--rm", "-i",
          "danielapatin/mcp-project-helper:latest",
          "-transport", "stdio"
        ]
      }
    }
  }
}

Claude Desktop

{
  "mcpServers": {
    "helper": {
      "command": "/absolute/path/to/mcp-project-helper",
      "args": ["-transport", "stdio"]
    }
  }
}

Adding Custom Tools

Create a JSON file in custom_prompts/ (see palette.json for an example).
Each tool must define a description and a prompt field.
The tool will be automatically registered and available via the MCP protocol.

Example Tools

tool-generator: Generates a tool description and prompt template based on a user query.
palette: Suggests a harmonious color palette for a given color.
