Which integrations are available for this server?

Automatically synchronizes prompt templates from GitHub repositories and includes specialized agents for GitHub workflows such as pull request reviews and repository exploration.

How do I use MCP Prompt Template Selector?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@MCP Prompt Template Selector find the best template for reviewing github pull requests" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

MCP Prompt Template Selector

MCP server that automatically selects and generates specialized prompts from a knowledge base of 66+ Claude Code system prompts. Uses LLM-powered semantic search to find the best matching template and adapts it to your specific task.

Features

Smart Template Selection — Semantic search across 66+ prompt templates using Claude Haiku
Adaptive Generation — Returns original template when it fits, customizes when adaptation is needed
Custom Templates — Add your own templates with priority over built-in ones
Dual Transport — Works via stdio (local) or HTTP (server deployment)
Zero Config — Templates auto-sync from claude-code-system-prompts

Requirements

Bun v1.0+
Anthropic API key

Installation

# Clone the repository
git clone https://github.com/YOUR_USERNAME/mcp-prompt-tool.git
cd mcp-prompt-tool

# Install dependencies
bun install

# Configure API key
echo "ANTHROPIC_API_KEY=your-api-key-here" > .env

Quick Start

Connect to Claude Code (recommended)

Add MCP server to Claude Code via command line:

claude mcp add --transport stdio prompt-template-selector -- bun run /path/to/mcp-prompt-tool/src/index.ts

Verify connection:

claude mcp list

Then in Claude Code use /mcp to see available tools.

Alternative: Run as HTTP server

bun run start:http
# Server runs at http://localhost:3000

Usage

Once connected, you have 4 tools available in Claude Code:

`list_templates`

Browse available templates:

list_templates category:agent
list_templates search:"code review"

`select_template`

Find best matching template for your task:

select_template task_description:"I need to review GitHub PRs"

`generate_prompt`

Generate a ready-to-use prompt:

generate_prompt task_description:"Agent for Python code refactoring" context:"Django, async migration"

`sync_templates`

Update templates from GitHub:

sync_templates force_reindex:true

Examples

Example 1: Code Review Agent

Request:

{
  "task_description": "Агент для code review Pull Request на GitHub",
  "prompt_type": "agent"
}

Result: Returns the original agent-prompt-review-pr-slash-command template as-is, since it's a perfect match.

You are an expert code reviewer. Follow these steps:

1. If no PR number is provided in the args, use ${BASH_TOOL_OBJECT.name}("gh pr list") to show open PRs
2. If a PR number is provided, use ${BASH_TOOL_OBJECT.name}("gh pr view <number>") to get PR details
3. Use ${BASH_TOOL_OBJECT.name}("gh pr diff <number>") to get the diff
4. Analyze the changes and provide a thorough code review...

Example 2: Custom Task with Adaptation

Request:

{
  "task_description": "Agent for legacy Python code analysis and migration to Python 3.12 async/await",
  "prompt_type": "agent",
  "context": "Django project with synchronous callbacks"
}

Result: Adapts the agent-prompt-plan-mode-enhanced template with Django/async specifics:

You are a Python code modernization specialist for legacy Django projects.
Your role is to analyze and plan refactoring of synchronous callback-based
code with migration to Python 3.12 and async/await patterns.

=== CRITICAL: READ-ONLY MODE ===
...

## Your Process
1. **Understand Requirements**: Focus on the legacy code patterns...
2. **Explore Thoroughly**: Find callback-based patterns and synchronous code...
3. **Design Solution**: Plan async context manager and async generator migrations...

Example 3: Listing Agent Templates

Request:

{
  "category": "agent",
  "search": "security"
}

Result:

{
  "total_count": 2,
  "templates": [
    {
      "name": "agent-prompt-security-review-slash",
      "purpose": "Conduct focused security reviews of code changes",
      "complexity": "complex"
    },
    {
      "name": "agent-prompt-bash-command-prefix-detection",
      "purpose": "Detecting command injection attacks",
      "complexity": "complex"
    }
  ]
}

Template Categories

Category	Count	Examples
`agent`	28	PR review, code exploration, security audit
`system`	10	Base behavior, plan mode, configuration
`tool`	19	Bash, Read, Edit, Grep tool descriptions
`reminder`	3	Plan mode reminders
`skill`	5	GitHub integration, specialized skills

Custom Templates

Add your own templates to custom-templates/ directory:

custom-templates/
├── my-agent.md           # Your custom prompt
└── metadata.json         # Optional: category, tags, priority

metadata.json:

{
  "templates": {
    "my-agent": {
      "category": "agent",
      "tags": ["custom", "specialized"],
      "priority": 10
    }
  }
}

Custom templates are prioritized over built-in ones during selection.
