MCP

Connect PaceUI MCP to your IDE to search and install free blocks directly into your codebase. Pro features like UI generation are authenticated via your API key.

Get your API key (Pro only)

Free tools (find-block, find-block-by-tags, add-block) work without an API key. If you want to use Pro features like UI generation (create-ui) or design migration (migrate-design):

Log in with the account you used to buy Pro.
Head over to /account/api-keys.
Create a new key and grab your token (PACEUI_API_KEY).

Quick AI setup (optional)

You can skip manual configuration entirely — paste this setup prompt into your editor's AI chat (Cursor, Windsurf, Claude Code, or Antigravity):

Prompt

https://paceui.com/mcp.md

Your AI assistant will read the instructions, verify your active IDE, and configure the PaceUI MCP server for you automatically.

Configure your IDE

Select your editor below to view its MCP configuration. Add the server under the name PaceUI with URL https://paceui.com/api/mcp:

Cursor

VS Code

Google Antigravity

Claude Desktop

Claude Code

Windsurf

Zed

Cline

{
  "mcpServers": {
    "PaceUI": {
      "type": "sse",
      "url": "https://paceui.com/api/mcp",
      "headers": {
        "Authorization": "Bearer ${PACEUI_API_KEY}"
      }
    }
  }
}

Use MCP in your workflow

Once connected, prompt your AI assistant directly in your project. The assistant will invoke the registered PaceUI tools:

Prompts

# Search free blocks
Search PaceUI for an analytics chart or pricing table block

# Install a block into your project
Add the PaceUI chat-composer block to my codebase

# Generate tailored UI (Pro)
Generate a user profile card using PaceUI tokens and motion

Available Tools

Tool	Access	Description
`find-block`	Free	Search PaceUI blocks by keyword, component name, or category

`migrate-design`	Pro	Migrate existing components to PaceUI standards and design tokens
`migrate-design-director`	Pro	Plan and coordinate multi-component design migrations

Troubleshooting

"Tool requires an active license"

This means you called a premium tool (create-ui, migrate-design) without an active license. Make sure:

You have an active Pro plan — verify on your account page
Your API key is passed in the Authorization header (Bearer <YOUR_API_KEY>)
The key is valid — regenerate it from Account → API Keys if needed

"Connection failed or SSE error"

If your editor cannot reach the server:

Confirm the endpoint URL is https://paceui.com/api/mcp
Verify that your editor supports SSE (Server-Sent Events) or HTTP transports
Reload your IDE window or restart the MCP server panel

"Zed IDE configuration"

Zed uses context_servers instead of mcpServers, and nests the endpoint in a settings block:

settings.json

{
  "context_servers": {
    "PaceUI": {
      "settings": {
        "url": "https://paceui.com/api/mcp",
        "headers": {
          "Authorization": "Bearer ${PACEUI_API_KEY}"
        }
      }
    }
  }
}
