MCP Prompt Template Server

A Model Context Protocol (MCP) server that provides standardized prompt templates for consistent AI-driven development workflows. This server exposes reusable prompt templates with variable substitution to ensure consistency across AI development tasks.

Features

• Prompt Templates: Reusable templates with variable substitution
• REST API: HTTP endpoints for integration with any application
• MCP Protocol: Native support for MCP clients like Claude Desktop, VS Code, etc.
• Type Safety: Full TypeScript implementation with validation
• Extensible: Easy to add new templates and customize existing ones

Quick Start

Installation

npm install

Build

npm run build

1. code-generation - Generate code based on requirements and language
2. code-review - Review code for quality, security, and best practices
3. api-documentation - Generate comprehensive API documentation

MCP Integration

With Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "prompt-server": {
      "command": "node",
      "args": ["C:\\path\\to\\mcp\\build\\index.js"]
    }
  }
}

With VS Code

Create .vscode/mcp.json:

{
  "servers": {
    "prompt-server": {
      "type": "stdio", 
      "command": "node",
      "args": ["C:\\path\\to\\mcp\\build\\index.js"]
    }
  }
}

Template Format

Templates use simple variable substitution:

{
  "id": "example",
  "name": "Example Template",
  "description": "An example prompt template",
  "template": "Generate {{language}} code for {{functionality}}. Requirements: {{#each requirements}}- {{this}}{{/each}}",
  "variables": [
    {
      "name": "language",
      "description": "Programming language",
      "required": true,
      "type": "string"
    }
  ],
  "category": "development",
  "tags": ["coding", "example"]
}

Development

Add New Templates

1. Edit data/prompts.json
2. Add your template following the schema
3. Restart the server

Run Tests

npm test

Lint Code

npm run lint

Next Steps

• Add prompt versioning
• Create web UI for template management
• Add more template categories (documentation, testing, deployment)
• Implement template sharing/import functionality
