ablaut MCP

Use ablaut from Claude Code, Cursor, or any MCP-capable agent. One command:

claude mcp add ablaut -- npx -y @v4nn4/ablaut-mcp

Or add it to any MCP client configuration:

{
  "mcpServers": {
    "ablaut": {
      "command": "npx",
      "args": ["-y", "@v4nn4/ablaut-mcp"],
      "env": { "ABLAUT_API_KEY": "your-key" }
    }
  }
}

The hosted API behind it is in early access. Request a key through the API dialog and set it as ABLAUT_API_KEY.
