This is a Model Context Protocol (MCP) server that gives Claude direct access to the entire SkillGalaxy skills library. Instead of manually downloading .md files, Claude can search, browse, and retrieve skills on demand.

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json
  • Linux: ~/.config/Claude/claude_desktop_config.json

Add the SkillGalaxy server entry:

{
  "mcpServers": {
    "skillgalaxy": {
      "command": "node",
      "args": ["/FULL/PATH/TO/skill_galaxy/mcp-server/index.js"]
    }
  }
}
⚠️

How It Works

┌──────────────────┐ stdio (JSON-RPC) ┌──────────────────┐ │ Claude Desktop │ ◄──────────────────────────► │ SkillGalaxy MCP │ │ │ │ Server │ │ "Find AI skills"│ ──── tools/call ──────────► │ │ │ │ ◄─── search results ────── │ 208 skills │ │ │ │ 16 categories │ │ "Get that skill"│ ──── tools/call ──────────► │ │ │ │ ◄─── full .md content ──── │ │ └──────────────────┘ └──────────────────┘

The server communicates over stdio using the MCP JSON-RPC protocol. Claude Desktop launches it as a subprocess — no ports, no network, no auth needed.

Development

Test the server manually

Pipe JSON-RPC messages to test the server:

# Test the server manually (pipe JSON-RPC messages)
echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"test","version":"1.0.0"}}}' | node index.js

Rebuild skills data

After editing js/db.js, rebuild the skills data:

# Rebuild skills data after editing js/db.js
npm run build-skills
