Authorization (optional)

Optional. 'Bearer jid_live_...' from https://jid.com/pricing (free key, no card, 1,000 checks a month). Without it, calls are rate-limited per IP.

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.

check_email

Checks whether an e-mail is from who it claims. Input: the raw headers of a message (as shown by Show original or View source). Returns checks and a read (headline, recommendation engage | verify_first | do_not_engage, failed checks, lookup links): DMARC/SPF/DKIM as the receiving server recorded them, DKIM alignment with From, Reply-To going to another domain, and a From domain or display name that imitates a known business. The headers are processed in memory and never stored. Deterministic, no AI. Counts as 1 check with a key; free tier without one.

qualify_counterparty

Qualifies a business that made contact (a form submission, an inquiry, an outreach reply). Input: the sender's e-mail (or the company domain), the company name if given, and the context (form type, message, stated value, stated role). Jid checks the domain (MX, SPF, DMARC, registration date over RDAP, the website), matches it to a Jid business file, reads that file's registrations, licences, filings, capital raises, loans and adverse records, and returns signals (each with source, source_url, verified_at), three scores (legitimacy, capacity, consistency, 0 to 100 with reasons), checks (each pass, fail or unknown with one line of evidence) and a read: a one-line headline ("Passed all 7 checks Jid could run. Recommendation: engage."), the recommendation (engage, verify_first, do_not_engage), the failed checks and up to 4 links to verify by hand, plus a signed receipt reference. detail "full" adds each signal's raw value, each check's lookup link and the full signed receipt. Businesses only: personal webmail or no matched business returns individual_or_unverified with no scores. A possible list match is returned as 'review', not as a finding. Counts as 2 checks with a key; free tier without one. Not intended for credit, employment, insurance or housing decisions about any person.

read-only

Argument	Type	Description
site	string	The submitting website's domain (binds the signal token)
email	string	Sender's e-mail address
detail	string	compact (default): signals without raw values and a receipt reference; full: raw signal values and the full signed receipt
domain	string	Company domain, when no e-mail is available

Input: any of domain, url, email, phone or company_name, the context (lead, inbound_email, partnership, vendor, purchase, marketplace_seller, agent_action), an optional amount (USD) and a policy (strict, balanced, permissive; default balanced). Returns engage (true or false), risk (low, medium, high, unknown), confidence 0 to 1, subject_type, reasons (each with source and evidence), mitigations, checks, a read (headline, recommendation engage | verify_first | do_not_engage, failed checks, lookup links) and a signed receipt_id. Deterministic, no AI in the decision, usually under a second. A possible sanctions name match returns engage=false with 'manual review', not a finding. For individuals only technical checks of the address, phone or domain run. engage is advisory. Rules: https://jid.com/screen-rules. Counts as 1 check with a key; free tier without one.

read-only

Argument	Type	Description
url	string	Website or page URL (purchase checks: only the host is used)
