Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

Tool list from our last check. Connect live to refresh it.

accept_retest_quote

Accept the quote from request_retest and pay the quoted total via x402 (USDC on Base) — paid automatically by your x402 MCP client. On settlement the re-test request is recorded (status paid, tx stored) and queued. Input: the exact service_name and quote_total_usd from your quote.

service_namestring, required

Exact service name, as listed by search_services (free)

quote_total_usdnumber, required

Total from the request_retest quote you are accepting

reasonstring

Why a re-test is needed (stored with the request)

This tool isn't marked read-only, so it may change something on the server or in an account you connected.

I understand, run it anyway

request_retest

Get an upfront quote for UseTested to re-test a service we have already reviewed — e.g. its quality changed, the review is stale, or measured numbers no longer match reality. Free. Returns the exact total: $1.00 rubric fee + the service's current advertised per-call price x 10 probe calls. To proceed, pay the quote via accept_retest_quote. The service must exist in our directory (find the exact name via search_services, free).

request_review

Request that UseTested buy and test an agent-economy service (x402 endpoint, MCP server, AI API) we haven't reviewed yet. Free. Queues the service for evaluation consideration — requests factor into which services we test next. No SLA or guaranteed verdict.

Argument	Type	Description

requestor_id	string	Identity tag for the request ledger. Leave unset for normal use.
