These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

get_rates

Current buy/sell rates for a currency across Uruguayan exchange houses (casas de cambio): market average, best buy/sell house, lowest spread, and the full per-house list. Excludes BCU and interbank quotes. Currency is an ISO code like USD, EUR, ARS, BRL.

best_house

The single best casa de cambio right now to buy or sell a currency. side='buy' means you buy the currency (best = lowest sell price); side='sell' means you sell it (best = highest buy price).

convert

Convert an amount between currencies using the best available Uruguayan market rates. Foreign↔foreign routes through UYU (Uruguayan peso). Codes: USD, EUR, ARS, BRL, UYU, etc.

list_houses

All Uruguayan exchange houses (casas de cambio) tracked, with display name, website, and departments served.

get_evolution

Historical rate series and statistics (min/max/avg/current/change) for a given exchange house (origin) and currency over the last N months. Use list_houses for valid origin ids.

get_news

Latest Uruguayan dollar/economy headlines (Google News), de-duplicated and newest first.

daily_summary

AI-generated analysis of the Uruguayan exchange market. Without a currency, a whole-market summary; with one, a per-currency analysis. lang is es | en | pt.

// known CVEs in dependencies2 critical3 high1 low

Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

7/7 tools missing one or more hints — get_rates (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); best_house (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); convert (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tool test coverage

Only 1/7 tools referenced in tests (14%)

Write tests that reference each tool by name so every tool has at least one test.

Production dependencies are patched

0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Dev dependencies

2 critical/high in dev-only deps (does not ship to users)

Upgrade dev dependencies when convenient.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
