What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs on your computer
Transport: stdio
Category: Search & AI memory

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
The registry lists no key to fill in.

You need

npmNode.js installed (for the npx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "uwarp": {
      "command": "npx",
      "args": [
        "-y",
        "uwarp-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add uwarp -- npx -y uwarp-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "uwarp": {
      "command": "npx",
      "args": [
        "-y",
        "uwarp-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "uwarp": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "uwarp-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

Common questions

Is Uwarp safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 23 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

uwarp-mcp

MCP server for Uwarp — a directory of 500+ free browser UI tools.

This package exposes three local tools you can use from Cursor or Claude Desktop. No paid API key is required. Most Uwarp listings are third-party embeds; this server does not scrape or wrap them. Contrast and palette math run entirely on-device; search_tools reads a bundled local catalog (data/tools.json).

Tool	Purpose
`check_contrast`	WCAG 2.x contrast ratio + AA/AAA flags
`generate_palette`	HSL harmony palettes + `:root` CSS
`search_tools`	Search the local Uwarp tool catalog

Author / context: Sherotree · https://uwarp.design · MIT

Install via npx

No clone needed. Add to your MCP client config (Cursor mcp.json, Claude Desktop, etc.):

"mcpServers": { "uwarp": { "command": "npx", "args": ["-y", "uwarp-mcp"] } } }

Requirements

Node.js 18+

Install & build

cd /path/to/uwarp-mcp

npm install npm run build

Test

npm test

Includes a check that black-on-white contrast ≈ 21.

Run locally (stdio)

npm start

or during development:

npm run dev

The process speaks MCP over stdio (JSON-RPC on stdin/stdout). Log noise goes to stderr.

Optional env stub

Variable	Notes
`UWARP_API_KEY`	Reserved for a future Uwarp API. Ignored today — no paid key needed.

Cursor (`mcp.json`)

Add to your Cursor MCP config (e.g. ~/.cursor/mcp.json or project .cursor/mcp.json). Point args at the built entry after npm run build:

"mcpServers": { "uwarp": { "command": "node", "args": ["/ABSOLUTE/PATH/TO/uwarp-mcp/dist/index.js"] } } }

Example if the project lives at ~/code/uwarp-mcp (use the absolute path):

"mcpServers": { "uwarp": { "command": "node", "args": ["/Users/you/code/uwarp-mcp/dist/index.js"] } } }

Restart Cursor (or reload MCP servers) after saving.

Claude Desktop

Edit the Claude Desktop config:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

"mcpServers": { "uwarp": { "command": "node", "args": ["/ABSOLUTE/PATH/TO/uwarp-mcp/dist/index.js"] } } }

Restart Claude Desktop after saving.

Tool reference

`check_contrast`

Input

Field	Type	Description
`foreground`	string	Hex `#RGB` / `#RRGGBB`
`background`	string	Hex `#RGB` / `#RRGGBB`

Output

"ratio": 21, "aa_normal": true, "aa_large": true, "aaa_normal": true, "aaa_large": true }

Uses WCAG 2.x relative luminance and contrast ratio thresholds (AA normal ≥ 4.5, AA large ≥ 3, AAA normal ≥ 7, AAA large ≥ 4.5).

`generate_palette`

Input

Field	Type	Default	Description
`seed`	string	—	Seed hex
`harmony`	`analogous` \	`complementary` \	`triadic` \	`mono`	`analogous`	Harmony mode
`count`	number	`6`	Colors, 3–12

Output

"colors": [{ "name": "Mid Blue", "hex": "#3b82f6" }], "css": ":root {\n --color-1: #3b82f6; /* Mid Blue */\n}" }

`search_tools`

Input

Field	Type	Default	Description
`query`	string	—	Search text
`category`	string	—	Optional filter (e.g. `color`, `svg-generators`)
`limit`	number	`8`	Max results, 1–20

Output

"tools": [ { "name": "Contrast Checker", "summary": "…", "url": "https://uwarp.design/tools/contrast-checker", "category": "color" } ] }

Note: search_tools uses the local catalog in data/tools.json (sample entries for development). It does not scrape uwarp.design at runtime.
