Overview

AI-generated overview

Lets an assistant look up sourced US federal 2026 tax brackets, standard deductions, and payroll and retirement contribution limits.

What it does
This remote MCP server exposes reference data on US federal taxes for the 2026 tax year. According to its description, it covers tax brackets, standard deductions, and payroll and retirement limits, with sources cited. No individual tools are listed in the manifest, so the exact query interface is not documented here.
When to use it
Useful when an assistant needs current US federal tax figures for 2026, such as answering questions about brackets, deductions, or contribution limits, or checking numbers in a tax-related task. It is a reference lookup, not a filing or calculation service.
Requirements
It is a remote streamable HTTP endpoint at databutler.dev; nothing needs to be installed locally. The manifest declares no authentication, no environment variables, and no headers, so no account or API key appears to be required. Network access to the endpoint is needed.
Before you install
The manifest declares no credentials, and the description mentions no write, send, or delete actions, so the server appears read-only. Because it is a third-party remote service, queries are sent to databutler.dev; do not include personal or confidential tax information in requests. Verify figures against official IRS sources before relying on them.
