Limits & pricing
Proposed quotas and metered pricing for the MCP server. MCP access would be included in every Review Expert plan, plus a free tier that an agent can sign up for on its own.
| Plan | Subscription | Tool calls / month | Requests / minute | Apps | Beyond included calls |
|---|---|---|---|---|---|
| Agent Free | $0 (proposed new tier) | 500 | 10 | 1 | Hard cap — upgrade to continue |
| Starter | $49/mo or $39/mo billed annually (current plan) | 5,000 | 30 | 2 | $5 per 10,000 additional tool calls |
| Pro | $149/mo or $119/mo billed annually (current plan) | 25,000 | 120 | 4 | $5 per 10,000 additional tool calls |
| Enterprise | $399/mo or $319/mo billed annually (current plan) | 100,000 | 600 | 10 | $5 per 10,000 additional tool calls |
MCP limits and metered pricing are proposed: planned, subject to change. Subscription prices are today's Review Expert plans. See pricing.
What counts as a tool call
- Each successful
tools/callcounts as one call, including each page of a paginated result. - Protocol traffic (
initialize,tools/list,resources/list, pings) and failed calls don't count. - Quotas reset at the start of each billing month.
Overage
On paid plans, calls beyond the included amount would be billed at $5 per 10,000 calls through Stripe metered billing, on the same invoice as your subscription. Owners would be able to set a monthly spending cap. On Agent Free, calls stop at the cap until the team upgrades.
Rate-limit headers
| Header | Meaning |
|---|---|
| RateLimit-Limit | Requests allowed in the current one-minute window. |
| RateLimit-Remaining | Requests left in the current window. |
| RateLimit-Reset | Seconds until the window resets. |
| X-RX-Usage-Month | Tool calls used this billing month. |
| X-RX-Quota-Month | Tool calls included in your plan this month. |
| Retry-After | Sent with HTTP 429: seconds to wait before retrying. |
Handling 429 responses
When the per-minute limit or the monthly quota is reached, the server responds with HTTP 429 and a Retry-After header. Wait at least that many seconds before retrying, and back off further on repeated 429s.
