Latest Exchange Rate Fetching With 15 Minute Ttl Caching

via “latest exchange rate fetching with 15-minute ttl caching”

** - MCP server acting as an interface to the [Frankfurter API](https://frankfurter.dev/) for currency exchange data.

Unique: Uses FastMCP's async tool registration with explicit TTL caching layer (not relying on HTTP cache headers), allowing predictable cache behavior independent of Frankfurter API's cache directives. Cache is managed in-process with automatic expiration, reducing redundant API calls for high-frequency agent interactions.

vs others: More efficient than calling Frankfurter API directly on every agent step (reduces latency and API load), but simpler than implementing a distributed cache like Redis since it targets single-server deployments (Claude Desktop, local VS Code)
