What is the Tax MCP server?

AI-powered tax calculator ai MCP server for agents. Supports calculate income tax, calculate vat. Exposed over MCP by the tax mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

Calculate income tax (UK/US brackets), EU VAT, UK corporation tax, and capital gains tax. Provides estimates only - not professional tax advice.

Adding it to your client

@smithery/cli on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Its toolset

Everything the assistant can do here goes through one of these:

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 9 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Tax.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the tax mcp server does with a few real requests.

When to reach for it

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Tax's toolset — Well, Production-ready, Pro and 6 more — is a fair guide to whether it matches your workflow. It is maintained by CSOAI-ORG; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
