Your agent can see the balance and what each tool costs at any time, so it can plan its work to fit, and it is told clearly when credits run out. **Status:** Closed testing · Invitation only · Tool interfaces may change ## What's changing As we move towards an open beta, we are introducing a weekly allowance for usage of the MCP server. Usage is monitored per organization, and based on a credits system, with different tools costing different amounts of credits. Credits reset every Monday at 00:00 UTC. ### Ask your agent about credit usage To help you and your agent manage usage, the MCP server will now report everything you need to know about your organization's credit balance, how many credits each tool costs, and when the allowance resets. This will typically be picked up by your agent at the beginning of a session, but you can also ask for it directly: > *"How many credits do we have left this week, and what does each tool cost?"* Credit information comes via the [`get_orgs_and_workspaces`](/api/mcp/get_orgs_and_workspaces) tool. ### What do I get charged for? Credits are only spent when a call succeeds. Any call that fails, returns an error, or times out is not counted against your allowance, so retrying after a problem doesn't cost twice. Some calls are always free: * **Discovery**: Listing your organizations and workspaces, and checking your credit balance * **Paging**: Fetching the next page of results a tool has already returned. Only the first page of a listing is charged This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
