Overview Installation

Overview

Opentax is a Model Context Protocol (MCP) server: Verifiable US tax oracle for AI agents: cited, machine-checkable federal and state tax computation. Because it speaks the Model Context Protocol, AI assistants can use Opentax as a set of callable tools instead of you copy-pasting between apps.

You can run Opentax two ways: connect to the hosted endpoint at https://opentax.invaro.ai/mcp with no local install, or run it on your own machine via the npm package @invaro/opentax. The current release is v0.2.1.

On mcp.site, Opentax sits in the AI & Agents category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below. If you maintain Opentax for Invaro, claim this listing to verify ownership, earn the Verified badge, and keep the details current.

▸Hosted endpoint — Streamable HTTP · https://opentax.invaro.ai/mcp

▸npm package — @invaro/opentax · MCP over stdio
