What you get

One tool per platform, plus capabilities and check_balance, at https://api.zomler.com/mcp. Every answer is the envelope: what was measured, when, what was left out and why, and what it cost. Fresh fetches spend credits; anything already held is free.

The connection appears under Connections in the dashboard, with when it was last used. Disconnecting stops it immediately.
