Promptopia MCP

A powerful Model Context Protocol (MCP) server for managing, organizing, and reusing prompt templates with variable substitution and multi-message conversation structures.

Introduction

Promptopia MCP is a comprehensive MCP server that enables AI applications to efficiently manage prompt templates through the Model Context Protocol. The server provides persistent storage for both single-content prompts and sophisticated multi-message conversation templates, complete with automatic variable detection, substitution capabilities, and seamless integration with MCP-compatible AI clients.

Built with TypeScript and designed for scalability, Promptopia MCP transforms how you work with AI prompts by providing a centralized, reusable prompt management system that integrates directly into your AI workflow through the standardized MCP protocol.

Why Use This Server?

• Centralized Prompt Management: Store, organize, and version all your prompt templates in one secure location with filesystem persistence, eliminating scattered prompt files and ensuring consistency across projects.

• Advanced Multi-Message Support: Create sophisticated conversation templates with role-based message structures (user/assistant) that support both text and image content, enabling complex AI interaction patterns.

• Intelligent Variable Substitution: Automatically detect variables using {{variable}} syntax and apply dynamic values at runtime, making your prompts flexible and reusable across different contexts and use cases.

• Seamless MCP Integration: Native MCP protocol support means your prompts automatically become available as first-class resources in Claude Desktop, IDEs, and other MCP-compatible applications without additional configuration.

• Future-Proof Architecture: Built with extensibility in mind, supporting prompt chains, conditional logic, versioning, and advanced workflow patterns for evolving AI interaction needs.

Features

Core Prompt Management

• Create and Store Prompts: Add both single-content and multi-message prompts with automatic variable detection

• Retrieve and List: Access individual prompts by ID or browse all available templates with metadata

• Update and Delete: Modify existing prompts or remove outdated templates with full CRUD operations

• Variable Application: Replace template variables with actual values for immediate use

Multi-Message Conversation Support

• Role-Based Messages: Structure conversations with explicit user and assistant message roles

• Mixed Content Types: Support for text and image content within the same conversation template

• Cross-Message Variables: Extract and apply variables across multiple messages in a conversation

• Format Conversion: Seamlessly convert between single-content and multi-message formats as needed

MCP Protocol Integration

• Native MCP Prompts: Expose stored prompts as MCP prompts for direct use in compatible applications

• Tool-Based Access: Complete set of MCP tools for prompt management operations

• Standardized Communication: Full compliance with MCP protocol specifications for reliable integration

• Real-Time Variable Resolution: Apply variables through the MCP protocol for dynamic prompt execution

Advanced Capabilities

• Automatic Variable Detection: Parse {{variable}} patterns from prompt content with intelligent extraction

• Backward Compatibility: Maintain support for existing single-content prompts while adding new features

• File System Persistence: Reliable JSON-based storage with organized directory structure

• Error Handling: Comprehensive error management with informative MCP-compliant error responses

• Type Safety: Full TypeScript implementation with robust type definitions and validation

Planned Features

• Conditional Logic: Add branching and conditional execution to prompt templates

• Version Control: Track changes and maintain prompt history with rollback capabilities

• Search and Tagging: Organize prompts with metadata and full-text search functionality

• Import/Export: Backup and share prompt collections across different environments

Installation

Installing via Smithery

To install Promptopia for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @lumile/promptopia-mcp --client claude

Option 1: NPX (Recommended)

Add this configuration to your Claude Desktop config file:

{
  "mcpServers": {
    "promptopia-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "promptopia-mcp"
      ],
      "env": {
        "PROMPTS_DIR": "<YOUR_PROMPTS_DIR>"
      }
    }
  }
}

Option 2: Local Installation

1. Clone the repository

2. Install dependencies:

npm install

3. Build the server:

npm run build

4. Add this configuration to your Claude Desktop config:

{
  "mcpServers": {
    "promptopia-mcp": {
      "command": "node",
      "args": [
        "/path/to/promptopia-mcp/build/index.js"
      ],
      "env": {
        "PROMPTS_DIR": "<YOUR_PROMPTS_DIR>"
      }
    }
  }
}

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.
