Quickstart

The Muro MCP server is public. The colour tools need no account and no key. Painting a photo needs either a Muro API key or an x402 payment.

Endpoint (Streamable HTTP):

https://mcp.usemuro.com/mcp

1. Add the server

Pick your client.

Claude (claude.ai, Desktop, mobile)

Settings → Connectors → Add custom connector. Use this URL and leave authentication empty:

https://mcp.usemuro.com/account/mcp

You sign in to Muro when you connect, which also unlocks the painting tools. See Sign in with Muro (OAuth).

Claude Code

claude mcp add --transport http muro-colors https://mcp.usemuro.com/mcp

ChatGPT

Settings → Apps & Connectors → Advanced → turn on Developer mode, then Create a connector with this URL and OAuth. You sign in to Muro when you connect. Availability of custom connectors depends on your OpenAI plan.

https://mcp.usemuro.com/account/mcp

Cursor

Add to ~/.cursor/mcp.json, or to .cursor/mcp.json in a project:

{
  "mcpServers": {
    "muro-colors": {
      "url": "https://mcp.usemuro.com/mcp"
    }
  }
}

VS Code (Copilot agent mode)

Add to .vscode/mcp.json, then use it in agent mode:

{
  "servers": {
    "muro-colors": {
      "type": "http",
      "url": "https://mcp.usemuro.com/mcp"
    }
  }
}

Any other client

Clients that speak Streamable HTTP take the endpoint above. Clients that only start local servers can bridge it:

npx mcp-remote https://mcp.usemuro.com/mcp

2. Try a free call

Ask your assistant:

Search for the paint colour “agreeable gray”.

It calls search_paint_colors and returns Sherwin-Williams Agreeable Gray (SW 7029, #D1CBC1, LRV 79.8) with a link to its page on usemuro.com. Other questions to try:

• What is the Benjamin Moore version of Farrow & Ball Hague Blue?
• Find me a warm white from Dulux with LRV above 80.
• Which paint brands are sold in Poland?
• I have #D1CBC1 from a photo. Which Behr colour is closest?

The four colour tools (search_paint_colors, get_paint_color, find_equivalents, list_brands) are free. See the MCP overview.

3. Paint a photo

visualize_room, get_visualization, relight_room and get_credits are listed for everyone, but a call without payment answers with where to get access. Two ways to pay:

• A Muro API key. Painting spends the credits of your Muro account, the same as the app. Create a key and send it as a header: see API keys. In claude.ai and ChatGPT, which cannot send a header, sign in with Muro instead.
• x402, no account. An agent pays per call in USDC on Base. See x402.

Prices and limits are on Pricing and limits. Photos must be JPEG, PNG or WebP, up to 12 MB, 1 to 12 colours per call. The tool is described at visualize_room.

From the command line

The same catalogue, without an MCP client. Node 20 or newer:

npx usemuro colors search "agreeable gray"

See the CLI guide for painting from the terminal.
