Requirements

  • Ghostty installed and available in PATH
  • Node.js 18+ (or Bun for development)

Setup

As a Claude Code Plugin (Recommended)

See ghostty-config-plugin for one-command installation.

Standalone MCP Server

git clone https://github.com/shyuan/ghostty-config-mcp.git
cd ghostty-config-mcp
bun install
bun run build

Add to .mcp.json in your project directory:

{
  "mcpServers": {
    "ghostty-config": {
      "command": "node",
      "args": ["/path/to/ghostty-config-mcp/dist/index.js"]
    }
  }
}

Architecture

src/
├── index.ts          # MCP server entry point (StdioServerTransport)
├── lib/
│   ├── exec.ts       # node:child_process wrapper for ghostty CLI
│   └── parsers.ts    # CLI output parsers (8 parsers)
└── tools/            # One file per tool (11 tools)
  • Config docs are cached in-memory keyed by Ghostty version (~120 KB, shared by search and get tools)
  • All CLI execution goes through exec.ts with a 10s default timeout
  • Uses node:child_process for Bun + Node.js dual compatibility
  • Never writes to process.stdout (reserved for MCP stdio transport)
