Pricing
WebMCP Eval uses prepaid credits. One credit runs one billed evaluation of one public URL.
Starter pack
$26 13 evaluations
One-time payment, not a subscription.
$2 (one credit) per billed evaluation.
Credits expire 12 months after purchase. Unused credit isn't refunded when it expires.
Paid by card or Link on Stripe.
When an evaluation isn't billed
Not billed if the page doesn't load (no 2xx response) or neither page rendering nor model analysis succeeds. You still get the result, marked billed: false, and the $2 goes back to your balance.
Reloading credits
Credits are bought at webmcp-eval.com.
A purchase on this site creates a new access key. In ChatGPT, that is how you add credit: connect with the new key. Credit left on an old key stays on that key.
Your card is saved with Stripe for reloads you ask for. A reload is charged only after you approve the amount yourself in your browser. A tool call alone never charges it.
Larger volumes
Custom eval kits for larger volumes are available on request and contracted separately. Email support.
