What is the Model Context Protocol (MCP)?

MCP is an open standard created by Anthropic that lets AI coding assistants (like Cursor, Claude Desktop, and Windsurf) connect to external tools. Think of it as a USB-C port for AI — a universal way to plug in new capabilities without custom integrations.

Which IDEs and AI tools are compatible?

Any MCP-compatible client works, including Claude Desktop, Cursor, Windsurf, VS Code with Continue, and Zed. The server uses the standard stdio transport, so any tool implementing the MCP spec can connect.

Which tools work offline?

score_prompt, scan_prompt, and generate_cursorrules run entirely offline using local heuristics — no API calls, no data leaves your machine. optimize_prompt and browse_templates connect to the AI Prompt Architect API for full functionality.

Is the MCP server free?

Yes, the MCP server is completely free and open source. Offline tools (scoring, scanning, cursorrules) require no account. Online tools use your existing AI Prompt Architect API key if you have one, or work with the free tier limits.

Offline tools process everything locally — prompts never leave your machine. Online tools communicate over HTTPS with the AI Prompt Architect API. We never store or log the prompts you send. The server is open source so you can audit the code yourself.

AI Prompt Architect

Quick Answer: AI Prompt Architect's MCP server lets you score prompts (0–100), scan for security vulnerabilities, optimize with STCO, generate .cursorrules files, and browse templates — directly from your IDE via the Model Context Protocol.

5 Prompt Engineering Tools

Every tool is available right inside your AI assistant. No browser tabs, no context switching.

score_prompt

Offline

Rate any prompt 0–100 across clarity, specificity, structure, and context. Get actionable improvement tips.

scan_prompt

Offline

Detect injection attacks, data leaks, jailbreak attempts, and PII exposure in your prompts.

optimize_prompt

Online

Rewrite prompts using STCO methodology — Structure, Tone, Clarity, and Output format optimisation.

generate_cursorrules

Offline

Create .cursorrules files tailored to your tech stack, coding standards, and project conventions.

browse_templates

Online

Search and discover curated prompt templates by category, model, or use case from our library.

Setup in 30 Seconds

Copy the config below into your IDE's MCP settings file. That's it — no API keys needed for offline tools.

~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "aipromptarchitect": {
      "command": "npx",
      "args": ["-y", "@aipromptarchitect/mcp-server"]
    }
  }
}

How It Works

Three simple steps to supercharge your prompt workflow.

Install

One command to install the MCP server globally via npm.

Configure

Paste the JSON config into your IDE. Works with Claude, Cursor, Windsurf, and more.

Use

Ask your AI assistant to score, scan, or optimize prompts. It calls the tools automatically.
