Allowances and costs

Free access: Starter accounts receive $10 in monthly credits plus a $10 onboarding bonus, without a payment method. Keyless MCP is separately rate limited.
- Starter lists 10 Search queries per second.
- A numeric anonymous MCP quota was not confirmed in the reviewed MCP guide.
What still needs checking
- Account plan quotas must not be treated as the anonymous MCP allowance.
- Authenticated MCP using OAuth or x-api-key is documented for agent runs; the keyless option above does not enable them.
- Documentation was reviewed; no connection or provider tool was executed.
