Snippet Saver

A Model Context Protocol (MCP) server that lets AI coding tools save, list, and read code snippets. Build your personal code snippet library that Claude Code, Cursor, and other MCP-compatible tools can access.

What It Does

This MCP server provides three tools:

1. save_snippet - Save a code snippet with a name, language, and optional description
2. list_snippets - View all your saved snippets
3. read_snippet - Read a specific snippet back

Snippets are stored as individual files in ~/snippets/ directory for easy access.

Installation

1. Clone or download this project

2. Install dependencies:

   cd snippet-saver
   npm install
   

3. Configure Claude Code (choose one method):

   Method A: Using command line (recommended)

   claude mcp add --transport stdio snippet-saver -- node C:\Users\Grays\mcp-projects\snippet-saver\index.js
   

   Method B: Manual configuration Create or edit .mcp.json in your project root:

   {
     "mcpServers": {
       "snippet-saver": {
         "command": "node",
         "args": ["C:\\Users\\Grays\\mcp-projects\\snippet-saver\\index.js"]
       }
     }
   }
   

4. Reconnect servers in Claude Code:

   • Type /mcp in Claude Code
   • Or start a new session

Usage Examples

Save a Snippet

Claude, save this React hook as a snippet:

const useLocalStorage = (key, initialValue) => {
  const [value, setValue] = useState(() => {
    const item = localStorage.getItem(key);
    return item ? JSON.parse(item) : initialValue;
  });

  useEffect(() => {
    localStorage.setItem(key, JSON.stringify(value));
  }, [key, value]);

  return [value, setValue];
};

Name it "useLocalStorage", language "javascript"

List All Snippets

Claude, what snippets do I have saved?

Claude, show me the useLocalStorage snippet

How It Works

• Snippets are stored in ~/snippets/ (your home directory)
• Each snippet is saved as a separate file with the language extension
• Metadata (name, language, description, date) is included as comments
• Works with any MCP-compatible AI coding tool

Limitations

• Snippets are stored as plain text files (no database)
• No search functionality yet
• Cannot update existing snippets (must save new version)
• No categorization or tagging system

Requirements

• Node.js v16 or higher
• Claude Code or another MCP-compatible tool
