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.

compare_pricing Read-only

Dated price comparison of two listed tools, from the vendor-verified plans in the directory: each tool's lowest paid plan, what it is priced per (flat, per seat, per mailbox), how it is billed, and the monthly total for a team of team_size. Prices that are unverified, older than 90 days or changed on the vendor page are left out, and then no comparison is returned. Tools priced per different units or billed differently are stated but not compared. Numbers and sums are computed in code, with the as-of date and the compare page URL to cite.

First tool slug, for example "instantly".

recommend_stack

Ranked shortlist per stack slot for a job. job is a slug from /jobs, /list-building or /persona. Job slugs: verify-an-email, find-a-mobile-number, waterfall-enrichment, enrich-a-company-by-domain, find-a-work-email, monitor-buying-signals, linkedin-active-buyers, local-businesses, ecommerce-stores, public-record-industries; persona slugs are listed at /persona. Common phrasings such as "find-a-contact" are resolved and echoed as resolved_from; an unknown slug returns the closest matches. Constraints keep only tools with a vendor-verified match (an unverified tool is left out, not judged lacking). Each tool gets a fact-only reason and a page URL. Deterministic, no AI call.

job*	string	Job, list-building or persona slug, for example "verify-an-email".
