Not in Muse's Connectors list yet, but Muse can still use it. Copy the request below and paste it into Muse. Muse asks before it shares anything with the app's site.

Also use it in ChatGPT or Claude
Rinkel MCP is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
Add it to ChatGPT
- 1
Open ChatGPT settings
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
- 2
Turn on developer mode
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
- 3
Create the connector
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.
- 4
Use it in a chat
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
Add it to Claude
- 1
Open Claude settings
In Claude, open Settings, then Connectors.

rinkel_list_callsList call detail records (inbound and outbound calls) with date, direction, status (ANSWERED, MISSED, VOICEMAIL, ANSWERING_SERVICE), duration, external and internal number, the users involved, notes, and (when the account has Rinkel AI insights) the AI summary and sentiment. Use rinkel_get_callGet one call detail record by its Rinkel id (the `id` field of rinkel_list_calls): numbers, users, status, duration, notes, voicemail and call-recording ids, AI insights. Rinkel API: GET /call-detail-records/{id}.rinkel_get_call_by_network_idGet one call detail record by its network `callId` (the id Rinkel sends in webhook events), optionally with insights and notes. Rinkel API: GET /call-detail-records/by-call-id/{callId}.rinkel_get_call_transcriptionGet the raw transcription of a call by its network `callId` (needs Rinkel AI insights on the account; 404 when the call has none). Rinkel API: GET /call-detail-records/by-call-id/{callId}/transcription.rinkel_get_call_recording_urlGet a temporary URL (valid 3 hours) to stream or download a call recording. The id is `callRecording.id` of a call record. Append `download` as a query parameter to the URL to download instead of stream. Rinkel API: GET /call-recordings/{id}/stream.rinkel_list_voicemailsList voicemail messages (call records with status VOICEMAIL): caller, date, duration, whether new, and the voicemail id. Newest first. With is_new=true Rinkel ignores every other filter and returns only unplayed voicemails. Rinkel API: GET /voicemails.rinkel_count_new_voicemailsNumber of voicemails that have not been played yet. Rinkel API: GET /voicemails/new-count.rinkel_get_voicemail_urlGet a temporary URL (valid 3 hours) to stream or download a voicemail. The id is `voicemail.id` of a call or voicemail record. Rinkel API: GET /voicemails/{id}/stream.rinkel_list_contactsList the contacts shared with everyone in the account (plus the Rinkel system contact, tag 'system'): names, company, phone numbers, email. Rinkel API: GET /contacts.rinkel_get_contactGet one contact by id. Rinkel API: GET /contacts/{id}.rinkel_find_contact_by_numberFind the contact that owns a phone number (E.164 such as +31612345678 works best). 404 when there is none. Rinkel API: GET /contacts/find-by-number/{number}.rinkel_list_usersList the account's users: name, email, phone number, role (ADMIN, USER, ANSWERINGSERVICE), availability schedule and status, and `fixed`/device info (`deviceId` is needed to start a call). Rinkel API: GET /users.rinkel_get_userGet one user by id, including preferences, notification settings, schedule and `deviceId`. Rinkel API: GET /users/{id}.rinkel_list_numbersList the account's Rinkel phone numbers: id, label, number, status (ACTIVE, SUSPENDED, PENDING_PORTING_IN ...), activation date and the users assigned. Rinkel API: GET /numbers.rinkel_get_numberGet one Rinkel number with its full dial plan: greeting, business hours schedule, call forwarding targets and ring logic, voice menu, call recording and caller-id settings. Rinkel API: GET /numbers/{id}.rinkel_list_recordingsList the uploaded audio recordings used in the dial plan (greetings, announcements, voice-over scripts): name, description, duration and where each is used. Not call recordings. Rinkel API: GET /recordings.rinkel_list_webhooksList the webhook subscriptions (events incomingCall, outgoingCall, callStart, callEnd, callInsights) with URL and active flag. Webhooks need the Expert plan. Rinkel API: GET /webhooks.rinkel_validate_phone_numberCheck a phone number for a country and return its normalised form. With check_inventory=true Rinkel also checks whether the number is available to order. Rinkel API: GET /misc/validate-phone-number.rinkel_add_call_noteWRITE: add a note to a call record (visible to everyone in the account who sees the call). The id is the call record's `id`; if Rinkel answers 404, retry with the record's `callId`. Rinkel API: PUT /call-detail-records/{callId}/note.rinkel_update_call_noteWRITE: replace the text of an existing note on a call record (the note id is in `notes[].id` of the call record). Rinkel API: PATCH /call-detail-records/{callId}/note/{noteId}.rinkel_delete_call_noteWRITE, irreversible: delete one note from a call record. Needs confirm=true after the user approved it. Rinkel API: DELETE /call-detail-records/{callId}/note/{noteId}.rinkel_create_contactWRITE: create a contact. It is shared with everyone in the Rinkel account (all users see it and calls from its numbers show its name). Rinkel API: POST /contacts.rinkel_update_contactWRITE: update a contact (PUT semantics). `numbers` is required and REPLACES all stored numbers, and an omitted default_outbound_number_id CLEARS it; omitted names, company and email keep their stored value. Read the contact first (rinkel_get_contact) and resend what must stay. Thrinkel_delete_contactWRITE, irreversible: delete a contact for the whole account. Needs confirm=true after the user approved it. The Rinkel system contact cannot be deleted. Rinkel API: DELETE /contacts/{id}.rinkel_block_numberWRITE: block a number from calling ANY of the account's numbers. Accepts an E.164 number, 'anonymous', or a prefix wildcard such as '+31*' (a wildcard must end the value and include a country code; a broad wildcard blocks every caller from that country). Undo with rinkel_unblock_rinkel_unblock_numberWRITE: remove a number (or the same wildcard pattern that was blocked) from the block list so it can call again. Rinkel API: DELETE /privacy/unblock-number.rinkel_start_callWRITE, COSTS CALL MINUTES: starts a real phone call. Rinkel rings the given user device first and, once it is answered, dials `to` using the chosen Rinkel number as caller id, so call charges apply to the account and the person called sees the number. Needs confirm=true, set onlyLink
