Requires an existing signed-in account with verified email; send its session Cookie header on the MCP request, or an agent key the account made at https://soc2compared.com/dashboard/agents as Authorization: Bearer. Identity and email come only from that session or key. Sign in or explicitly create an account at https://soc2compared.com/login?next=%2Fsubmit and verify its email before retrying. This tool creates no account and sends no verification email. Returns {httpStatus:201, id, slug, status:'Draft'}; research + the quality gate decide publication. Your own (url, session email) replay within 24h returns httpStatus:200. The fit check starts at once and usually answers within a minute: poll GET https://soc2compared.com/api/submissions/{id} and wait the Retry-After seconds it sends while fit is \"checking\". fit then reads \"accepted\" (it goes live, and the account is mailed), \"rejected\" (mailed with the reason) or \"undecided\" (a person looks within 2 days). No session: {httpStatus:401, error:'sign_in_required', message, loginUrl}. Unverified session: {httpStatus:403, error:'email_unverified', message, email, remediation}. Company gate: the account's address, or an address it proved with a code, must be on the submitted website's domain; otherwise {httpStatus:403, error:'domain_unverified', message, domain, remediation, ownerUrl, skip} — POST /api/domain-proof/start {url, email} mails a 6-digit code to an address at that domain, POST /api/domain-proof/verify {proofId, code} redeems it, then submit again. Submitting for someone with no mailbox of your own at the domain? Give the owner ownerUrl (the submit page with the site filled in): they prove it there with a code, or skip the proof as skip says. Personal mailboxes (gmail, outlook…) never prove a domain. No refusal creates a listing. Validation returns 400; duplicate/claim responses return 409. Read tools remain keyless.",
