Delphi Doc MCP

中文版

A Model Context Protocol (MCP) server that provides seamless access to Delphi documentation directly within your AI coding assistant.

Features

• 📚 Multi-Source Documentation - Access both RAD Studio VCL and DevExpress VCL documentation
• 🔍 Smart Search - Full-text search with wildcard (*, ?) and fuzzy matching support
• ⚡ Fast & Cached - Local caching for quick subsequent lookups
• 🤖 AI-Friendly - Structured Markdown output optimized for LLM consumption

Quick Start

Installation

From npm (recommended):

npm install -g delphi-doc-mcp

From source:

git clone https://github.com/LinFallen/delphi-doc-mcp.git
cd delphi-doc-mcp
npm install
npm run build

Note: On first run, the server will automatically crawl documentation. This takes a few minutes but only happens once. Data is stored in ~/.delphi-doc-mcp/.

Configure Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

      "command": "npx",
      "args": ["delphi-doc-mcp@latest"]
    }
  }
}

Note: On first run, the server will automatically crawl documentation (~2-5 minutes). Data is cached in ~/.delphi-doc-mcp/.
