Overview

AI-generated overview

Local MCP server that lets an assistant calculate U.S. car sales tax, title and registration fees, with calculators for TX, CA, FL, NY and PA and rates for…

What you can do
  • Compute car sales tax for a vehicle purchase, with dedicated calculators for Texas, California, Florida, New York and Pennsylvania.
  • Estimate title and registration fees alongside the tax figure.
  • Look up state-level sales tax rates covering all 50 states.
  • No tool list is published, so the exact operations and inputs are not documented beyond these calculators.
When to use it
Useful when someone is budgeting a vehicle purchase or comparing the out-the-door cost of buying a car in different U.S. states and wants tax, title and registration estimates inside the assistant conversation.
Requirements
Runs locally over stdio as the PyPI package us-car-sales-tax, launched with uvx, so a Python environment with uv/uvx is needed. No authentication, environment variables or headers are declared. Desktop client only; not available as a web executable.
Before you install
Figures are estimates from published state rates and calculator logic; verify them against the state or local tax authority before relying on them for a purchase. No tool list or README is provided, so behavior and inputs are not documented.

Installation

In SourceWeft

  1. Open U.S. Car Sales Tax in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Tools

SourceWeft started this package once in an isolated sandbox, without credentials, to list its tools. That failed: the server did not start.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
