Official Mexican public data for AI agents: Banxico rates, INEGI inflation, UMA and ISR tables.
这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。
我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。
选择你使用的 AI 应用,然后复制设置。
BANXICO_TOKEN, INEGI_TOKEN标为机密的值是你账户的钥匙。千万不要分享给别人,也不要粘贴到聊天里。
你需要
你用的是哪个应用?
在上方选择你的应用。我们会记住它,下次按钮会显示“安装到 …”。
打开 Claude Desktop → Settings → Developer → Edit Config,把下面的内容粘贴到 claude_desktop_config.json
{
"mcpServers": {
"mexico": {
"command": "uvx",
"args": [
"mcp-mexico"
],
"env": {
"BANXICO_TOKEN": "your-value",
"INEGI_TOKEN": "your-value"
}
}
}
}在终端中运行这条命令
claude mcp add mexico --env BANXICO_TOKEN=your-value --env INEGI_TOKEN=your-value -- uvx mcp-mexico运行前请先填写空着的值。
粘贴到项目中的 .cursor/mcp.json,或 ~/.cursor/mcp.json

"env": {
"BANXICO_TOKEN": "your-value",
"INEGI_TOKEN": "your-value"
}
}
}
}浏览器会先询问是否打开应用,然后应用会显示设置并请你确认。密钥的值会留空,由你自己填写。

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.*
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.
| 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.
Both are free and take a couple of minutes.
You can start with only one token, or none: tools whose token is missing return a message explaining how to get it.
You need uv. The server runs with uvx mcp-mexico; you don't start it yourself, your MCP client does.
claude mcp add mcp-mexico -e BANXICO_TOKEN=your-token -e INEGI_TOKEN=your-token -- uvx mcp-mexico
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" } } } }
Add the same mcpServers block to ~/.cursor/mcp.json.
Ask your assistant:
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.
| 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.
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.
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.
