How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security50

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_fix_rate FIX exchange rate ~80

What is the mcp-mexico server?
mcp-mexico is listed in the public MCP registry as io.github.DiegoTepichin/mcp-mexico. Official Mexican public data for AI agents: Banxico rates, INEGI inflation, UMA and ISR tables. This page covers its PyPI package (mcp-mexico).
Is the mcp-mexico server safe to use?
mcp-mexico scores 59 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 4 November 2026. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the mcp-mexico server expose?
mcp-mexico exposes 8 tools: get_uma, get_isr_table, get_fix_rate, get_fix_rate_range, get_interest_rate, and 3 more. Their descriptions and schemas cost roughly 729 tokens of context every time the server is loaded.
Is the mcp-mexico server still maintained?
mcp-mexico is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the mcp-mexico server under?
mcp-mexico declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
