Antevo Trademark is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Screened, no issues found
Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.
screen_markScreens one brand name against trademark registers. No account needed. Returns the registered and pending marks closest to the name (up to 25), each with a similarity tier, and the registers those marks are filed in. EU marks come from EUIPO's search; the other registers are readcheck_namesScreens a shortlist of up to 15 candidate names in one call: the trademarks on file near each name, the companies registered under it, and whether its domains are registered. Ranks them fewest conflicts first: by how close the nearest mark is, then by companies registered under tsuggest_classesWhich Nice classes a business like this files in. No account needed, and no register is searched: it maps the description onto the Nice classification. The question people cannot answer for themselves: not "is my name taken" but "taken in WHAT". Nice has 45 classes and the numberholder_readWho a holder is and how they file — the read on an adversary. Free. Computed from their whole register book: how much of it they let lapse, whether their marks cluster where they trade or spray across unrelated classes, and the leverage that gives counsel. Returns the evidence beopposition_windowHow long you have to oppose a filing in a given trademark office, and from when. Twenty registers, each with the provision the window comes from. The trap this answers: most offices run opposition BEFORE registration, from publication of the application, but a minority — Switzerlfiling_landscapeFiling activity in a Nice class — volume by month and the busiest filers. Signed-in. Answers "how crowded is my space" and "who keeps filing near me". Pass a Nice class (9, 42, 36…), optionally an office code ('EM', 'US', 'GB', 'CH'), and a window in months. EVERY COUNT IS OF OURmy_conflictsEverything currently near the names this user watches.my_deadlinesRenewals and closing opposition windows for this user. Each deadline has a `kind`: `opposition` carries a real date; `window_pending` means a filing is still in examination and nothing is running yet; `window_unknown` means a live threat whose deadline cannot be dated; `window_clmy_watchesThe names this user is watching.company_fileA holder's WHOLE book across every office. Founder and up. Corporate identity from PermID (organisation, HQ, PermID) comes with `company.attribution`, its CC BY 4.0 credit. follow_filerFollow an adversary — every filing they make, anywhere. Studio and up. Different from watching a name: this catches what they do NEXT, which is usually a different name in a class the user doesn't hold. watch_markStart watching a brand name: new filings near it show up as conflicts. Optionally takes Nice classes as a comma-separated list ('9,42'); blank watches every class. dismiss_conflictClear one hit as not-a-threat. Reversible — it moves to the Cleared list. Takes `jurisdiction` and `app_no` exactly as they appear on a conflict in the user's conflict list. A cleared hit, such as an unrelated business or the user's own filing, stops being surfaced. filer_activityWhat the filers this user follows have filed lately. Studio and up.run_investigationResearch a trademark holder on the open web and return a cited dossier: who they really are (an operating company, a shell, a known squatter), their notable trademark activity or disputes, and any red flags. Signed-in. Spends one credit — included credits first, then purchased onget_credit_balanceHow many credits this user can spend and what each paid tool costs, in credits. Free to call. `remaining` is what can be spent now: `monthly_left` (included with their plan, resets each month) plus `topup_balance` (bought, never expires). `prices` is credits per call, by tool. https://trademark.antevo.ch/mcpNot in Muse's Connectors list yet, but Muse can still use it.
