On 2026-10-20 the server answered initialize and tools/list without a sign-in. First answer in 551 ms.

• Its tools do none of the product's use cases we checked: host IUCLID and Chesar in an EU cloud; check dossiers for hidden errors before submission; submit dossiers to REACH-IT automatically via API.
• Checked on 2 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• get_catalog_templates

  Return the enabled ApplicationTemplate catalog, ordered by name. Call this to discuss trial and template options with a prospect or customer before starting a trial. If this doesn't answer your question, call `start_inquiry` to ask 4chems…

• list_consents

  Return the caller's own recorded consents plus the tenant-scope consents of every tenant where the caller is at least a viewer. Call this to check which legal documents have already been accepted before asking again. Pass `tenant_id` to…

• record_consent

  Record acceptance of a legal document version and return the entry; call this only after showing the user the document URL and version and receiving an explicit affirmative answer.

• start_inquiry

  Store an anonymous inquiry draft and email a 6-digit verification code. Ask the user for the code, then call verify_inquiry with the returned challenge_id and code — the inquiry reaches 4chems only after that verification succeeds.

• verify_inquiry

  Verify the 6-digit code and deliver the inquiry to the helpdesk inbox.

• accept_invitation

  Accept a pending invitation and grant the invitee's first role assignment. Call this when an invitee has a valid invite link and wants to join the tenant; single-use, consuming the token marks it accepted.

• verify_device_login

  Poll a device login to token issuance (UC-091, RFC 8628). Anonymous. While the human has not signed in yet it answers `{"status": "pending", "retry_after": <seconds>}`: wait `retry_after` seconds and call again with the same…

  Verify the emailed 6-digit code (`challenge_id`, `code`) and create the 4chems account. Never guess or retry codes, and never ask the user for a password.
