Overview

AI-generated overview

Remote MCP server for Mexico's INPC consumer price index: monthly values, inflation between months, and the Art. 17-A tax update factor.

What you can do
  • Look up the INPC value for a given month, or the latest published value when no month is given.
  • Compute the Art. 17-A CFF tax update factor for late payments, refunds or balances, with truncation and a floor of 1.
  • Compute INPC variation (accumulated inflation) and the ratio between two months without the fiscal rules, for indexed rents, pensions or contracts.
When to use it
Useful when an assistant needs official Mexican inflation figures, for example answering what the INPC was in a given month, adjusting an indexed amount, or estimating a fiscal update factor under Art. 17-A.
Requirements
Remote streamable HTTP endpoint; no authentication, environment variables or headers declared. Network access to the endpoint is needed.
Before you install
Results are described as indicative and meant to be verified, and the server asks that its source and notices be cited. Fiscal factor results should be checked before being used in filings or payments.

Installation

In SourceWeft

  1. Open INPC México 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/com.rigolco%2Finpc-mexico/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
