Common questions

Is Untax safe?

It passed 3 of 3 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 in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.4.2) reached the registry 13 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Untax MCP & Agent Plugin (v0.4.4)

Research county property assessments, compare available records, and prepare a free private veteran review PDF from a saved review you select. Missing facts stay visible. A draft does not establish eligibility or authorize filing.

Quick start

  1. Follow the Untax setup guide to connect a supported assistant to https://untax.io/mcp.
  2. Ask about a property's available assessment records, a public VA office, or an official VA form. These public lookups require no account or API key. Check the response for sources and missing information.
  3. If you request a private review or test checkout, follow the browser sign-in link and review the requested permissions.

Version 0.4.4 updates package descriptions and instructions. Existing connections and account permissions are unchanged. Read the release notes or release history.
