Prontto

Connect Prontto to your AI assistant

Prontto is an MCP server: ChatGPT, Claude, Cursor, VS Code and any MCP client can read your requests, review deliverables, build quotes and more — as you, with your permissions. Sign-in happens in the client; nothing to configure on our side.

Server URL
https://portal.prontto.co/api/mcp

ChatGPT

Add Prontto as a custom app. When Prontto is listed in the ChatGPT app directory this becomes one click; until then it takes five.

  1. Open ChatGPT on the web → Settings → Apps → Advanced settings, and turn on Developer mode.
  2. Still under Settings → Apps, choose Create.
  3. Name it "Prontto", paste the server URL above, and pick OAuth as the authentication.
  4. Click Scan Tools, sign in with your Prontto account and approve the access, then click Create.
  5. Open a new chat, select Prontto from the tools menu, and ask, for example, "what needs my attention today?"

No Developer mode in your settings? It is not offered on every plan. On Business, Enterprise and Edu workspaces an admin turns it on first, under Workspace settings → Apps, and publishes the app for everyone else. The ChatGPT desktop app can also add the server directly.

Claude

Works on claude.ai, Claude Desktop and the mobile apps — one connector, everywhere you use Claude.

  1. Open Claude → Settings → Connectors → Add custom connector.
  2. Name it "Prontto" and paste the server URL above. Leave the OAuth client fields empty.
  3. Click Add, then Connect — sign in with your Prontto account and approve the access.
  4. Turn Prontto on in the tools menu of a chat.

Claude Code

One command in the terminal; the sign-in opens in your browser.

  1. Run the command below.
  2. Type /mcp in Claude Code and authenticate Prontto.
Command
claude mcp add --transport http prontto https://portal.prontto.co/api/mcp

Cursor

Cursor accepts an install link — the button prefills everything.

Install in one click
  1. Click Install, confirm in Cursor, then sign in when prompted.
  2. Or add the server manually under Cursor Settings → MCP.

VS Code

VS Code (GitHub Copilot) accepts an install link too.

Install in one click
  1. Click Install, confirm in VS Code, then sign in when prompted.
  2. Or run "MCP: Add Server" from the command palette and paste the URL.

Any other MCP client

Streamable HTTP with OAuth 2.1 (dynamic client registration, PKCE). Paste the config below, or use an API key as a bearer token.

  1. Add the server with the JSON below.
  2. Clients that cannot open a browser can send an API key as Authorization: Bearer instead.
Configuration
{
  "mcpServers": {
    "prontto": {
      "type": "http",
      "url": "https://portal.prontto.co/api/mcp"
    }
  }
}

Scripts and automations without a browser

Create a personal API key in your Prontto settings and send it as a bearer token to the same URL, or to the REST API.

Open settings

No account? Let your assistant start the design

Ask ChatGPT, Claude or any assistant for the kitchen or closet you want, with its measurements. It sends you a link that opens the 3D planner with your room built to size and a first layout of cabinets placed, ready to adjust. Signing up is free and happens on the link.

Try: “Design an L-shaped kitchen, 3.2 by 2.8 metres, Nordic style.”

For assistants: the public MCP server https://portal.prontto.co/api/mcp/public (no account needed) has start_design and browse_catalogue.

For AI agents

If you are an AI assistant reading this page on someone's behalf, this is everything you need. Follow it, then tell the person what changed and what you can now do for them.

  1. Read the agent brief at https://portal.prontto.co/llms.txt. It states the endpoint, the authentication, the conventions and where to start.
  2. If your client supports MCP, connect to https://portal.prontto.co/api/mcp over Streamable HTTP. Authentication is OAuth 2.1 with dynamic client registration and PKCE, so no credentials are needed up front. The person signs in and approves in their browser.
  3. If your client cannot speak MCP, use the REST API at https://portal.prontto.co/api/v1. The person creates an API key in their Prontto settings and you send it as a bearer token.
  4. Full reference: https://portal.prontto.co/api/docs. Machine-readable schema: https://portal.prontto.co/api/v1/openapi.json.

You act as the person who signed in, with their permissions. Destructive and money operations refuse to run until you pass confirm, and return a preview instead.
