nearest-tailwind-colors-mcp

Model Context Protocol (MCP) server that exposes a single tool for finding the nearest Tailwind CSS palette colors to any CSS color.

Install & build

• Requires Node 18+.

• Install deps: npm install.

• Build the project: npm run build.

Related MCP server: huetension mcp

Configure in an MCP host

All hosts should point to the built entry: /absolute/path/to/nearest-tailwind-colors-mcp/dist/index.js.

• JSON-based hosts (Claude Desktop, Cursor, VS Code MCP extension): add this to the relevant settings.json/claude_desktop_config.json, then restart/reload:

{
  "mcpServers": {
    "nearest-tailwind-colors": {
      "command": "node",
      "args": ["/absolute/path/to/nearest-tailwind-colors-mcp/dist/index.js"]
    }
  }
}

• Claude Desktop: edit claude_desktop_config.json.

• Cursor: Settings → search "Model Context Protocol" → "Edit in settings.json".

• VS Code: User/Workspace settings.json with the MCP/Claude extension installed.

• ChatGPT Codex (CLI and VS Code extension): add to ~/.codex/config.toml (wrap in your shell if you need nvm/fnm to enforce node >= 18):

[mcp_servers.nearest_tailwind_colors]
command = "node"
args = ["/absolute/path/to/nearest-tailwind-colors-mcp/dist/index.js"]

# with nvm
[mcp_servers.nearest_tailwind_colors]
command = "zsh"
args = [
  "-lc",
  "export NVM_DIR=\"$HOME/.nvm\"; source \"$NVM_DIR/nvm.sh\"; nvm use 20 >/dev/null; node /absolute/path/to/nearest-tailwind-colors-mcp/dist/index.js",
]
