Verified Numbers
io.github.jfortier93Published by GitHub account jfortier93v1.0.0Updated Oct 24, 2026
Current source-cited 2026 US tax constants and calculators for AI agents; every answer cites IRS.
The publisher's own server: Numbers Online — phone intelligence
Overview
Gives an assistant current, source-cited 2026 US federal tax constants and calculators, with every answer citing its IRS source and verification date.
- What you can do
- Provides nine tools covering IRS standard mileage rates by date and purpose, mileage deductions, self-employment tax with wage-base cap and Additional Medicare, progressive federal income tax by filing status, standard deductions with age and blindness additions, simplified quarterly estimated tax with optional safe-harbor comparison, 2026 retirement and HSA limits, estimated-tax deadlines, and data provenance. Each response includes the number, effective window, primary source, last-verified date, and a disclaimer. It refuses rather than guesses when a filing status or date falls outside verified data.
- When to use it
- Useful for bookkeeping, invoicing, planning, or tax-estimate workflows where a model's remembered tax figures may be stale, especially after mid-year IRS rate changes. Best when the assistant needs a cited, dated federal tax constant rather than a recalled one. Not intended for state or local tax, or for advice-grade tax planning.
- Requirements
- Remote streamable HTTP endpoint at or connection through the MCPize client command. No authentication, environment variables, or headers are declared. The README also documents a local stdio option requiring Python and the mcp package, but no package is declared in the manifest.
Installation
In SourceWeft
- Open Verified Numbers in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.jfortier93%2Fverified-numbers-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Other MCP clients
Add this to your client's mcpServers config.
