Kontato 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.
provisionACTIVATES the Kontato account for the given phone: creates it only if it does not exist yet; if it exists, reuses the SAME account (calling it with an existing account is normal and expected: it works like a login). IDEMPOTENT BY PHONE: safe to call again in any session or after verify_numberConfirms the owner number with the 6-digit OTP that arrived on their WhatsApp after `provision`. REQUIRED before sending, scheduling or calling: until verified, `send`/`reply`/`schedule`/`call` return 403 owner_not_verified. If the code expired or failed too many times, call agaischeduleRegisters a recurring or one-time delivery in the Kontato scheduler. At the scheduled time, Kontato runs the `prompt` as a full agent (with web search) and delivers the result to the owner's WhatsApp. USE THIS for "send me X every day": you do not need to stay online or promise flist_schedulesLists the scheduled deliveries (recurring or one-time) of this account, with the next run.cancel_scheduleCancels a scheduled delivery by its schedule_id (from `list_schedules` or `schedule`).sendSends a WhatsApp message through Kontato's bridge number. SAFE CASE: if you OMIT "to", it is delivered to the OWNER's own WhatsApp (self-notification). Other numbers must be AUTHORIZED first with `authorize_recipient` (the person replies SIM/yes on WhatsApp); otherwise the send ireplyReplies to a specific number that messaged the bridge number. Same as `send`, but "to" is REQUIRED. Replying to whoever wrote to you is safer than cold outbound.list_messagesLists the message history of the bridge number (received and sent), newest first. Use it to decide whom to answer with `reply`.statusShows the Kontato account state: active or not, bridge number, and the schedules already registered. Use it to honor the turn-based rule: before saying something will be delivered "every day", confirm here that an active schedule exists.callPlaces a phone call to the account OWNER (the person who verified their number), spoken by Kontato's voice assistant on your behalf. Use it when something deserves the owner's attention now, or when you need a decision and they are away from the screen. Modes: "notify" reads a meget_callReturns the state of a call placed with `call`. While running, state is "queued", "ringing", "in_progress" or "processing". When state is "finished", read: outcome ("answered", "no_instruction", "decide_later", "completed", "voicemail", "no_answer", "busy", "interrupted", "timed_authorize_recipientAsks a phone number for permission to receive messages from this account. By default an account only messages its OWNER; any other number must be authorized: Kontato sends an invite on WhatsApp and the person must reply SIM (yes). Until then, `send`/`reply` to that number are reflist_recipientsLists the numbers this account may message besides the owner, with their status ("authorized" or "pending").https://api.kontato.ai/mcpNot in Muse's Connectors list yet, but Muse can still use it.
