delible-mcp

MCP server for Delible — generate and iterate on low-fidelity, hand-drawn sketch UI from prompts, straight from your AI client (Claude Code, Claude Desktop, or any MCP host).

Generation runs server-side on Delible and consumes your Delible credits. Get an API key from the MCP page in your Delible account.

Usage

Add it to your MCP client config. The server runs over stdio via npx:

{
  "mcpServers": {
    "delible": {
      "command": "npx",
      "args": ["-y", "delible-mcp"],
      "env": {
        "DELIBLE_API_KEY": "your-key-here"
      }
    }
  }
}

Environment

| Variable | Required | Default | Purpose | |---|---|---|---| | DELIBLE_API_KEY | yes | — | Authenticates generation against your Delible account. | | DELIBLE_BASE_URL | no | https://app.delible.dev | Override the API base (e.g. local dev). | | DELIBLE_EDITABLE_CANVAS | no | off | Set to 1 to surface an editable_url for in-place click-to-edit alongside the read-only preview. |

Tools

• create_sketch — generate a new sketch from a prompt. count 2 or 4 produces that many divergent structural takes on the same screen.
• iterate_sketch — refine an existing sketch by slug, resuming the prior thread.
• publish_sketch — publish (or unpublish) a sketch to a permanent shareable URL.
• list_sketches — list recent sketches with thumbnails to pick one to iterate on.

Prompt

sketch — a one-shot entry point (exposed as /mcp__delible__sketch in Claude Code) that runs the full divergent-create → preview → pick → iterate loop.
