MCP Server Integration

Overview

Snapper includes an MCP (Model Context Protocol) server that exposes formatting tools to AI assistants like Claude Desktop and Claude Code.

Start it with:

snapper mcp

This launches the server on stdin/stdout using the MCP protocol.

The MCP feature must be enabled at build time:

cargo install snapper-fmt --features mcp

Configuration

Claude Desktop / Claude Code

Add to your MCP configuration:

{
  "mcpServers": {
    "snapper": {
      "command": "snapper",
      "args": ["mcp"]
    }
  }
}

Or with the npm wrapper:

{
  "mcpServers": {
    "snapper": {
      "command": "npx",
      "args": ["@turtletech/snapper-mcp"]
    }
  }
}
