Claude Skill

Add Ziptax as a Skill inside Claude Desktop

The Ziptax Claude Skill teaches Claude how to authenticate against the Ziptax API, call the rate-lookup endpoints, and reason about the response shape. Install it once and Claude can answer door-level sales tax questions inside any Claude Desktop conversation.

(Optional) Pair it with the Ziptax MCP Server

For live tool access, pair the Skill with the hosted Ziptax MCP server. A minimal claude_desktop_config.json looks like:

1{
2  "mcpServers": {
3    "ziptax": {
4      "command": "npx",
5      "args": [
6        "mcp-remote",
7        "https://mcp.zip-tax.com/?key=<your-api-key>"
8      ]
9    }
10  }
11}

Replace <your-api-key> with your Ziptax API key. This configuration uses the mcp-remote adapter and requires Node installed locally. See the MCP Server page for a direct HTTP configuration that doesn’t require Node.
