Overview

SureCheck MCP is a local stdio MCP server that exposes two tools, check_phone and check_email, backed by the SureCheck API. Phone checks return format, country, validity flags and line type from numbering-plan metadata; they are not live carrier, HLR or reachability lookups. Email checks cover syntax, MX or implicit mail routes, disposable-domain flags and role-address detection; they do not verify that a mailbox exists. API keys are currently invitation-only with a free beta of 100 checks per key. The hosted service runs on a shared single instance with cold starts and no uptime guarantee.
