Frankfurter API

Security checks across malware telemetry and agentic risk

Overview

This is a documentation-only currency exchange-rate helper that uses the public Frankfurter API and does not install code, handle credentials, or persist anything.

Before installing, understand that the skill may prompt your agent to call the public Frankfurter API for currency rates. The data is daily reference-rate data, not live trading data, so check returned dates and provider details for official, compliance-sensitive, or financial-decision use.

Vague Triggers

Medium
Confidence
93% confidence
Finding
The skill description says to use it for any exchange rate, currency conversion, forex, or historical FX data task, even when Frankfurter is not explicitly requested. This is an overly broad activation trigger that can cause the agent to invoke the skill in situations where it may be unnecessary, unexpected, or less appropriate than other tools, increasing the chance of unintended external requests and incorrect tool selection.
