01 · Install Haiku RAG

Claude Code

claude mcp add ggozad-haiku.rag -- uvx haiku-rag

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "ggozad-haiku.rag": {
      "command": "uvx",
      "args": [
        "haiku-rag"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
