Overview

AI-generated overview

Remote MCP service that independently checks whether the numbers in a finished table add up, returning a signed receipt.

What you can do
  • Verify arithmetic in a finished table: row totals, column totals and subtotals are checked for consistency.
  • Works on tables, spreadsheets, CSV/TSV files, markdown tables, cost breakdowns, invoices, quotations and budgets.
  • Produce an independent audit result with a signed receipt for the checked numbers.
When to use it
Use it when an assistant has produced or received a table, invoice, quotation, budget or cost breakdown and needs an independent arithmetic check before delivering it, rather than trusting its own calculation.
Requirements
A remote streamable HTTP endpoint; no local package, environment variables or headers are declared. No authentication is declared.
Before you install
The service receives the table data you submit for checking, so avoid sending confidential financial content unless that is acceptable. The instructions mention x402, which typically implies payment for requests; confirm any cost before relying on it.

Installation

In SourceWeft

  1. Open Agent Verifier — Independent Number Verification in the dashboard and add it to a workspace.
  2. 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.zenoix888%2Fagent-verifier/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.

Read the install guide the agent follows

Verify numbers in a finished table or breakdown

Verify that the numbers in a finished table add up — before you deliver it. Use this when you have produced or received a table, spreadsheet, CSV/TSV or markdown table, a cost breakdown, invoice, quotation or budget, and need an independent check that row totals, column totals and subtotals are arithmetically consistent, or that a list of line items sums to a stated total. Returns every mismatched cell with the recomputed value and the difference, plus a signed verification receipt (verification ID, UTC time, SHA-256 content hash). Checks arithmetic consistency only; does not verify source data. Not a calculator — it does not evaluate expressions; it audits finished numbers.
