This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

BANXICO_TOKEN secret env
Banxico SIE API token, needed for the exchange and interest rate tools.
INEGI_TOKEN secret env
INEGI Indicators API token, needed for the inflation tools.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is mcp-mexico safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: BANXICO_TOKEN, INEGI_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.3) reached the registry 17 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

mcp-mexico

MCP server that gives AI agents official Mexican public data: Banxico exchange and interest rates, INEGI inflation, UMA values and ISR tax tables.

Leer en español

*Claude Code using mcp-mexico. Response wait times are cut from the recording.*

Why

AI assistants either make up Mexican economic figures or use stale ones, so you end up looking them up by hand at Banxico, INEGI or the SAT and pasting them in. mcp-mexico lets any MCP client (Claude Desktop, Claude Code, Cursor) fetch them directly. Every result names its official source and the date it applies to.

Tools

Tool	What it returns	Source	Token
`get_fix_rate`	FIX USD/MXN exchange rate, latest or for a date. On weekends and holidays it returns the previous business day. Future dates are rejected.	Banxico SIE	`BANXICO_TOKEN`
`get_fix_rate_range`	Daily FIX between two dates (max 366 days).	Banxico SIE	`BANXICO_TOKEN`
`get_interest_rate`	Banxico target rate, 28-day TIIE, overnight TIIE de Fondeo or 28-day CETES; latest or for a date. Future dates are rejected.	Banxico SIE	`BANXICO_TOKEN`
`get_interest_rate_range`	One of those rates between two dates (max 366 days).	Banxico SIE	`BANXICO_TOKEN`
`get_inflation`	INPC index and monthly, annual and year-to-date inflation for a month (latest by default).	INEGI	`INEGI_TOKEN`
`get_inflation_range`	The same for each month in a range (max 240 months).	INEGI	`INEGI_TOKEN`
`get_uma`	UMA daily, monthly and annual values, 2020–2026, with validity dates.	INEGI	none
`get_isr_table`	ISR tables for individuals, 2020–2026: monthly (LISR Art. 96) and annual (LISR Art. 152).	Anexo 8 of the RMF (SAT / DOF)	none

get_uma and get_isr_table work offline with no configuration. Their data ships inside the package; each table cites the document it was taken from and the date it was verified.

The bundled UMA covers up to 2026. From 1 February 2027, get_uma returns an error until the package is updated, instead of a stale value.

Get your tokens

Both are free and take a couple of minutes.

Banxico: open the SIE API token page, solve the captcha and click "Generar token". The 64-character token appears on the page.
INEGI: enter your email in the INEGI token form. The token arrives by email.

You can start with only one token, or none: tools whose token is missing return a message explaining how to get it.

Install

You need uv. The server runs with uvx mcp-mexico; you don't start it yourself, your MCP client does.

Claude Code

claude mcp add mcp-mexico -e BANXICO_TOKEN=your-token -e INEGI_TOKEN=your-token -- uvx mcp-mexico

Claude Desktop

Add this to claude_desktop_config.json (Settings → Developer → Edit Config) and restart Claude Desktop:

"mcpServers": { "mcp-mexico": { "command": "uvx", "args": ["mcp-mexico"], "env": { "BANXICO_TOKEN": "your-token", "INEGI_TOKEN": "your-token" } } } }

Cursor

Add the same mcpServers block to ~/.cursor/mcp.json.

Try it

Ask your assistant:

"What is today's FIX exchange rate?"
"What was annual inflation in Mexico in December 2024?"
"How much is 30 UMAs in pesos this year?"
"Using the 2026 monthly ISR table, how much tax is withheld on a 25,000 peso salary?"

Does it help?

In a run of three small local models (1 to 3 billion parameters) on 18 questions about official figures, none answered a single one correctly from memory. With this server, llama3.2:3b answered 14 of 18 correctly and qwen2.5:1.5b 12 of 18; all four ISR questions failed for both, because they must pick the right row of the bracket table. One run, small models, exact figures: read the method and limits before quoting it.

Configuration

Variable	Required	Description
`BANXICO_TOKEN`	For Banxico tools	Banxico SIE API token.
`INEGI_TOKEN`	For INEGI tools	INEGI Indicators API token.

Responses are cached in memory only: up to 1 hour for latest values, 24 hours for past Banxico ranges and 6 hours for the INPC series. Nothing is written to disk.

Development

uv sync

uv run pytest uv run ruff check . && uv run ruff format --check . && uv run mypy . uv run mcp-mexico # starts the server over stdio

Tests never touch the network: they replay responses recorded from the real APIs. See CONTRIBUTING.md.

Disclaimer

This project is not affiliated with Banco de México, INEGI or the SAT. Figures come from their public sources, but check the cited source before relying on them for tax or legal decisions.
