How to connect Ziptax Sales Tax API
Ziptax Sales Tax API is a remote MCP server reached over the older SSE transport, at https://mcp.zip-tax.com/sse. Clients that support remote servers generally still accept SSE endpoints, though the protocol now favours Streamable HTTP.
The registry entry declares an HTTP header for the connection: X-API-KEY (required, secret). A secret header usually carries an API key or token issued by the service; clients that accept custom headers set it with the server's URL.
Derived from the registry entry, not tested here. What the server does, and on what terms, is set by its publisher; check its repository or website before giving it access to your accounts or files. How to add an MCP server to an assistant · Before you connect
