Physical Validation
Find labs and request research
Physical Validation by Halmos Labs helps you find CROs, CDMOs, and research facilities and compare their published claims with the sources behind them. Search by the work you need, location, and provider type. Results distinguish exact and partial matches and preserve unknowns. Prepare experiment requests for peptides, rabbits, mice, genes and plasmids, proteins and antibodies, sequencing, or other research work. Each request selects one service family. Supply inline specifications, contact details, provider preferences, and budget currency using the connected tools. A preparation call returns a link to review the request. Use the browser request page for file uploads. Catalogue reads are public. Connect your account through the host’s managed OAuth flow to list, read, delete, or submit existing drafts, including drafts started in the browser. Submit a complete request or a saved draft with your agreement and receive a submission receipt. Halmos reviews requests before supplier outreach. Existing draft edits and file uploads use the returned browser links. The plugin includes shared skills for discovery and evidence, experiment requests, and account drafts. Provider claims describe published capabilities, and current availability or suitability still needs confirmation. Data use follows the Physical Validation terms and privacy policy.

The server finds CROs and CDMOs, reads what each publishes with its evidence, and prepares or submits requests. Tools: , , , , , , , , , . Search text is q. country, region and providerType narrow a place or a kind of provider. facets lists exact filter values. A page's match is exact when a result answered the whole query and partial when nothing did and these are the closest. Each result carries its own match: one that answered all but one part of the question reads partial on an exact page, and sits below the results that answered it all. A company or facility record, including its physical-validation:// resource, carries what it publishes and the sources. Catalogue reads leave directory records and account drafts unchanged and contact no one. Direct submission requires an available MCP tool or an HTTP client that can send POST requests, account authorization, and the person's consent. Reading these instructions does not connect the MCP server or add tools to a chat. A successful submission returns a request ID. Chats without a connected tool can instead construct a populated browser review link using the plain JSON fragment format described at https://physicalvalidation.com/llms.txt; the person opens it to review and send. Opening a review link submits nothing. returns a link for browser review; it saves no account draft and submits no request. Account request tools use OAuth account authorization. Credentials and sign-in codes are not tool arguments. submits a complete request or saved draft with the person's consent through the connected MCP client. , and manage existing account drafts from https://physicalvalidation.com/request. Halmos reviews submitted requests; suppliers are not contacted automatically. Bulk scraping, mirroring or redistributing this site's data isn't allowed.
