That is a delay, not evidence.\nAnything not looked at is listed as not checked, with the reason.\n\nFIVE TOOLS\ncheck_identifier checks one identifier. check_text finds every identifier in one passage you paste or point to (a paragraph, a reference list, an abstract) at its exact position and checks each one; the passage itself is not stored, only the identifiers, their positions and a hash. get_report opens a report you already have by its id.\nrequest_human_verification asks a Metis researcher to verify the identifiers in one of your reports by hand: that each resolves to the work or entity the citation names, and what the registry and the source document say (not whether the surrounding argument is true). The result is filed on the same report as a signed addendum with the reviewer's name and the date. set_live_verification turns that on for every report the account files, for eight hours, and off again. Where an account does not include human verification, these two tools say so and file nothing.\n\nTHE REPORT\nEvery check ends in a report with a unique id (MC-XXXX-XXXX-XXXX), a public page, a PDF, signed receipts (the registry query, the HTTP status and the SHA-256 of the registry's answer) and a recheck button. Anyone with the link can recheck the report; the recheck asks the registries again, live, and is filed as a new report linked to the first. Reports also live on your Metis account page.\n\nWHAT IT DOES NOT DO\nIt does not grade a text true or false, and a report is not a statement that the surrounding text is accurate. It checks the identifiers in a text, not the argument around them. Registries are issuers or indexes: CourtListener is a case-law citation index, not the court that issued a decision. It does not read your conversation; it checks only the identifier or passage you give it.\n\nACCOUNT\nRequires a Metis account (sign in or create one when connecting). Checks count against the account's monthly allowance; the account page shows what has been used.","plugin_category_id":"productivity","privacy_policy_url":"https://mcp.metisfoundry.com/privacy","screenshot_urls":[],"short_description":"Checks citations at the source","terms_of_service_url":"https://mcp.metisfoundry.com/terms","website_url":"https://mcp.metisfoundry.com/docs"},"keywords":["citations","citation checker","DOI checker","verify references","hallucinated citations","references","DOI","PubMed","arXiv","ORCID","LEI","company number","case law","identifiers","registries","provenance","research integrity","fact check at the source"],"onboarding_skill_name":"setup","requires_local_executor":false,"skills":[{"description":"Use when the user asks to check or verify a citation, DOI, identifier, reference list, case citation, company or registry id, or whether a cited source exists.
