Tools

Tool	What it does	Effect	Inputs (* required)

Security and data handling

Your tool arguments are used only to answer that call. They are not saved to a database, shared, sold or used for training.
To make repeat lookups fast, some servers keep the public answer to a lookup in Cloudflare's edge cache for up to 7 days (most for 1 hour or less). It holds the public result, not who asked.
Free tier: a per-day counter keyed by a SHA-256 hash of your IP address and the date (in a Cloudflare Durable Object). The raw IP is not stored.
Paid key: the key is checked with the payment provider (Stripe; Polar for older keys) and the result is cached for 10 minutes; usage is counted per key per month.
No accounts, cookies or tracking on the MCP endpoint. Errors may appear in Cloudflare's short-lived Worker logs.
Every tool is read-only: it looks up public data and returns it. No tool writes, deletes, sends messages or spends money.
