Credits
Tool calls are paid in credits. Free tools cost nothing; billable tools cost between 1 and 10 credits per successful call, as listed on the Docs page. Each workspace has a per-credit rate set in its agreement (the standard rate is 2¢); your rate and each tool's cost per call are on the Billing page. Misses (a 404) and tool errors (a 500) are refunded automatically; you only pay for calls that returned a result.
Unused credits carry over from month to month.
Your plan
MCP is sold as an enterprise plan. Creating an account is free and needs no card. To start making calls, contact sales at [email protected]: our team agrees a per-credit rate and credit package with you, then switches access on for your workspace. Your exact pricing appears on your Billing page.
Until then the Billing page reads "Your workspace is awaiting activation", with a Contact sales button. API keys work, but every tool call, free tools included, returns a 402 "subscription_inactive" error.
The Billing page
- Plan summary: Enterprise and its status, Your rate per credit ("Negotiated rate for your team" or "Standard rate"), and your Credit balance with its dollar value at your rate.
- Per-tool pricing: each billable tool with Credits / call, Cost / call and Per 1,000 calls at your rate. A "negotiated" badge marks a tool priced specially for your team; free tools are listed under "Included at no cost".
- Recent activity: every credit movement with when, the activity and tool, the credits, and the balance after.
- Contact your team to add credits or change your rate. Customers billed by card from before enterprise pricing also see Payment settings, which opens the customer portal for the card and invoices.
When credits run out
A call that the balance can't cover returns a 402 "insufficient_credits" error that includes your balance and the amount required, so an agent can stop cleanly rather than fail mid-run. To add credits or change your rate, contact your account team; credits land in seconds. Only card-billed subscriptions refill on a billing date.
Frequently asked questions
Are credits shared across my API keys?
Yes. All keys in a workspace draw from one balance; the ledger and Top tools table show which key spent what.
What happens if my plan is paused?
The Billing page reads "Tool access is paused for this workspace" and tool calls return "subscription_inactive". Contact sales to reactivate.
Can I see spend per tool?
The dashboard's Top tools (30d) table shows calls and credits by tool, and the ledger shows every individual charge and refund.
