Visily MCP

Visily is an AI design canvas that turns text prompts, screenshots, URLs & more into UI designs that are as easy to edit as a Google Slide. The Visily MCP server brings those designs into your AI coding agent: point it at a Visily board or screen and your agent can find it, turn it into application code, or pull its theme tokens.

What you can do

• Turn a Visily design into code. Generate production-ready code from a Visily screen or board — whether the UI was AI-generated in Visily or hand-authored. The agent rebuilds semantic, responsive components (default stack: React + TypeScript + Tailwind v4 + shadcn/ui) instead of pasting a static export.
• Find a board or screen and get its link. Ask for a design by description ("the board I was working on for the 4.6 release") and the agent returns a link to open it — without leaving your editor.
• Apply a board's theme. Pull a board's design system as shadcn/Tailwind v4 tokens and apply it to another app's styling.

Install & connect

Authentication is OAuth — your client prompts you to sign in to Visily on first use. There are no API keys to manage.

The current Visily MCP server URL is:

https://app.visily.ai/api/mcp

Each platform's drop-in files live under plugins/<platform>/.

Claude Code

claude plugin marketplace add visily-app/mcp-plugins
claude plugin install visily@visily

Then reload Claude Code and run /mcp → select visily → complete the OAuth sign-in. Full walkthrough: installation-guides/claude.md.

Cursor

Cursor 2.5+ packaged plugin — install from a local clone in the agent chat:

/add-plugin ./plugins/cursor

Reload Cursor; the MCP server appears under Settings → MCP (OAuth on first use) and the Visily skill loads automatically. Details: plugins/cursor/README.md.

Cline

Cline can connect directly to the hosted Visily MCP server with Streamable HTTP:

{
  "mcpServers": {
    "visily": {
      "type": "streamableHttp",
      "url": "https://app.visily.ai/api/mcp"
    }
  }
}

Full agent-readable install guidance: llms-install.md.

Codex

codex plugin marketplace add visily-app/mcp-plugins
codex plugin add visily@visily

Authorize via OAuth on first use. Full walkthrough: installation-guides/codex.md.

ChatGPT

ChatGPT connects to remote MCP servers via Developer Mode custom connectors (Plus, Pro, Business, or Enterprise). Enable Settings → Connectors → Advanced → Developer mode, add a custom connector pointing at the server URL above, and complete OAuth. Then paste plugins/chatgpt/AGENTS.md into a Project/GPT's instructions. Steps: plugins/chatgpt/SETUP.md.

Antigravity

Copy plugins/antigravity/.agents/ into your project root and merge plugins/antigravity/mcp_config.json into your global MCP config. Details: installation-guides/antigravity.md.

Kiro

Copy plugins/kiro/ into your Kiro powers directory (it contains POWER.md, per-intent steering/ workflows, and mcp.json). Merge mcp.json into your Kiro MCP config and authorize via OAuth. The Power activates on Visily URLs and find/build/theme intents.

Replit Agent

Install the hosted Visily MCP server with a one-click Replit install link: installation-guides/replit.md.

Lovable

Commit plugins/lovable/AGENTS.md to your repo root and add the Visily MCP connector in the Lovable UI. Details: plugins/lovable/SETUP.md.

v0 (Vercel)

v0 supports custom MCP servers natively. Add the server URL above via Settings → MCP Connections (or Add MCP in the prompt form) and authorize via OAuth, then commit plugins/v0/AGENTS.md to your repo root. Details: plugins/v0/SETUP.md.

Other editors (Streamable HTTP)

Any client that supports Streamable-HTTP MCP can connect with this config:

{
  "mcpServers": {
    "visily": {
      "url": "https://app.visily.ai/api/mcp"
    }
  }
}

This covers VS Code (Copilot), Windsurf, Cline, Gemini CLI, and similar tools. Check your client's docs for where MCP server config lives; OAuth runs on first use.

Prompting your agent

Give the agent a Visily link and a clear intent. The agent extracts the IDs from the URL — it doesn't open the page.

Examples

• "Find the Visily board I was working on for the 4.6 release and give me the link."
• "Build this Visily screen as React + Tailwind: https://app.visily.ai/projects/abc/boards/456/elements/789"
• "Implement this board in Next.js, reusing my src/components/ui components."
• "Apply my Visily board theme to this app's globals.css."

A Visily URL looks like:

https://app.visily.ai/projects/{projectId}/boards/{boardId}/elements/{elementId}

Structure your Visily file for better code

The more intent your design carries, the better the generated code:

• Name your screens and key groups semantically in Visily — names flow into the export and into the link-matching for "find my board."
• Lean on Visily's theme / design system so the agent can apply real tokens instead of guessing colors and radii.
• Ask for one screen at a time for large boards — smaller selections produce more reliable results.

Tools

The server also ships prompts (e.g. find_visily_board, generate_code_from_element, apply_board_theme) and resources (visily://docs/...) that your agent reads on demand.

Custom rules (optional)

Set project-level guidance so output stays consistent — like onboarding notes for a new teammate.

Cursor (.cursor/rules/visily-quality.mdc):

---
description: Visily code-generation rules
alwaysApply: false
---
- Treat Visily `designData` as a reference, not final code — rebuild semantically.
- Apply the Visily `theme` tokens; never hardcode hex, radii, or spacing.
- Reuse existing components in `src/components/ui` instead of duplicating.
- Verify against `get_screenshot` for 1:1 layout before finishing.

Claude Code (CLAUDE.md):

## Visily MCP rules
- Treat Visily `designData` as a reference, not final code — rebuild semantically.
- Apply the Visily `theme` tokens; never hardcode hex, radii, or spacing.
- Reuse existing components instead of duplicating; verify with `get_screenshot`.
