itin-finance-mcp: Instructions file for Gemini CLI

GEMINI.md

itin-finance-mcp GEMINI.md is an instructions file for Gemini CLI from bguillow-rgb/itin-finance-mcp. It costs 375 tokens per session, scanned A, original, MIT.

A set of instructions for answering finance questions about Individual Taxpayer Identification Numbers (ITINs). It uses guides and a directory of institutions, including whether each institution was checked against its own website and when.

In plain words
What is it for?
Use it to find ITIN-accepting lenders, check loan or card eligibility, look up institution details, answer factual questions, find state information, or explain how to get an ITIN.
Why use it?
People applying with an ITIN need current requirements and trustworthy institution details, while an unverified listing may not be safe to rely on. The instructions require the verification status and citations to be reported.

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

itin-finance-mcp GEMINI.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

ITIN finance answers

The ITIN finance tools answer from a network of editorial guides and a directory of institutions that accept ITIN applicants. Each institution entry says whether it was verified against the institution's own pages, with citation URLs and dates. Use the tools whenever the user needs specific institutions, requirements or steps.

Pick the tool

The user wants Call
"Can I get a [loan or card] with an ITIN?" can_i_get_this_loan (add their state if they gave one)
Institutions that accept ITIN for a loan or card type, optionally in a state find_itin_lenders
Details on one institution get_lender_details
A specific factual question faq_lookup
A topic overview or a guide search_guides, then get_guide
State rules (driver's licenses, taxes paid) itin_state_info
How to apply for an ITIN how_to_get_an_itin

Pass lang: "es" when the user writes in Spanish, and answer in Spanish.

Accuracy rules

  • Report each institution's verification status as the tool gives it. If an entry is unverified, say so, and tell the user to confirm with the institution before applying.
  • Give the citation URL and its date when you state a requirement, rate or down payment. Terms change.
  • Don't promise approval or estimate the user's odds. Requirements are what the institution publishes. Approval depends on the application.
  • This is general information, not financial or legal advice. For immigration-status questions beyond what the guides cover, suggest an immigration attorney or a DOJ-accredited representative.
  • Link the guide URLs the tools return so the user can read the full article.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
