KaiCalls is not in Muse's Connectors list yet, and it needs you to sign in with your KaiCalls account. Apps that need this kind of sign-in usually cannot be used from a Muse chat yet. Follow it here and we will tell you when it reaches Muse.

KaiCalls 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.
request_human_approvalAsk a named principal for a specific decision using the provisioned voice approval channel. Requires restricted approvals:write, a configured callback host and signing secret. Returns dispatch status; the signed callback carries the decision and evidence. No approval is implied bconnect_agentConnect an external agent to a business and its signed event outbox. Requires current business admin membership, an assigned Kai agent, and agents:write, sms:write, webhooks:write. New SMS/WhatsApp conversations route to the external agent; explicit handoffs win. Grants no additiget_agent_connectionDiscover the external agent connection, signed webhook configuration, scoped API operation catalog, channel readiness and remaining runtime requirements. Requires agents:read, sms:read and webhooks:read. Configuration does not prove delivery or recipient consent.disconnect_agentDisconnect the external agent and disable its webhook atomically. Requires current business admin membership and agents:write, sms:write, webhooks:write. Pass the stored expected_revision.

Requires linked manager-account access. Dates are calendar dates inclusive at both ends. Source may lag by 30 minutes. Connected phone cget_lsa_setupInspect Google LSA account selection and sync freshness, with setup steps. Saved configuration never proves a live workflow. Cloud-project production access is not shown here; Google Cloud reports it.sync_lsaSync an explicitly selected connected LSA advertiser. Requires current business admin role. Syncing runs lead ingestion, and existing business speed-to-lead configuration may contact the new leads it finds.list_lsa_leadsList synced Google LSA leads, charge and credit states, source IDs and rating details. The returned LSA lead id identifies the lead in LSA commands; the separate lead_id field links to the CRM.get_lsa_conversationsRead the latest 200 synced Google LSA conversation events for an LSA lead, including customer and advertiser messages. History is as current as the last sync.get_lsa_reportReport LSA lead counts, types, observed statuses, ratings and credit counts for an explicit UTC window (start inclusive, end exclusive). Includes sync freshness and completeness. Removed unrated leads are counted separately because they cannot be rated here. Financial amounts, sisend_lsa_replySend an authorized text reply inside an existing Google LSA message lead through the Ads API. This contacts the customer. Requires current business admin role and a stable idempotency_key. A retry with the same key is deduplicated; pending/unknown writes are blocked. Provider accrate_lsa_leadSubmit an authorized, truthful Google LSA quality survey and return Google's actual bonus-credit decision. This is not a guaranteed refund or the retired manual dispute workflow. Requires admin role and a stable retry key. Each rating is a per-lead survey answer based on that leaget_callrailRead a business's CallRail call-tracking setup. action=status returns the connected CallRail account, which CallRail companies feed which business, every company the saved key can see (with its company_id), and the businesses you can link them to. action=list_trackers (with link_manage_callrailConnect CallRail call tracking to a business's line. Order: (1) connect {api_key, account_id?}; (2) get_callrail status lists the companies the key can see; (3) link_company {company_id, target_business_id?} once per business; (4) set_writeback {enabled}; (5) get_callrail list_trget_nimbataRead a business's Nimbata call-tracking setup: the connected Nimbata account, which Nimbata projects feed which business (with when each last synced and how many calls matched), the projects the saved token can see, and the businesses you can link them to.manage_nimbataConnect Nimbata call tracking to a business's line. connect {api_token} checks and saves a Nimbata personal API token (Agency plan; one token can serve many businesses). link_project {project_id, target_business_id?} attaches that Nimbata project's calls to a business and adds Kaagency_profile_bootstrapRegisters a new agency for the signed-in user and makes them its owner, using the given brand and support details. Requires a signed-in user session with a verified email; an API key cannot create an agency. Repeating it for an agency that already exists does not create a second agency_profile_updateReplaces the agency brand, support details and requested commercial mode. Requires an agency owner or admin and the current profile revision; a stale revision is rejected. It does not change any published offer.agency_profile_inviteCreates a staff invitation for an email address with the admin, operator or reader role and returns a one-time invite link that expires in 7 days. Requires an agency owner or admin; only the owner can invite an admin. It sends no email; the returned link is delivered by whoever cagency_profile_accept_inviteJoins the agency using the token from an invite link.

Accepting the same invite again is a no-op.agency_profile_revoke_inviteCancels a pending staff invitation so its link can no longer be used. Requires an agency owner or admin. It does not remove anyone who already accepted; revoke_member does that.agency_profile_assignGives an active agency staff member access to one client business with the admin or member business role. Requires an agency owner or admin who can manage that client; only the owner can assign an admin staff member. Assigning an existing assignment again changes nothing.agency_profile_unassignRemoves a staff member's agency assignment to one client business, and removes the business membership if this assignment created it.

Requires an agency owner or admin; only the owner can remove an admin, and the owner cannot be removed.agency_profile_issue_keyCreates a new API key for yourself in this agency, limited to the requested scopes, and returns the secret once.

Each call creates another keyagency_offer_saveCreates a new offer draft, or replaces an existing draft when offerId and its current revision are given. Requires an agency owner or admin. Saving changes only the draft; clients see nothing until it is published.agency_offer_previewBuilds the publishable manifest and sales kit for an offer draft and returns its fingerprint and revision for publishing. Requires an agency owner or admin. It saves nothing and fails if a package release, variant or claim is not supported.agency_offer_publishPublishes the previewed offer as a new immutable version and returns its enrollment link.

Publishing the same fingerprint again returagency_offer_archiveArchives an offer so it can no longer be published or used for new enrollments. Requires an agency owner or admin and the current offer revision. Existing installations are not removed.agency_enrollment_start_self_serviceStarts a business owner's own enrollment in a published agency offer, using the business name and intake facts.

Nothing is installed until the owner approves andagency_enrollment_finish_self_serviceCompletes a self-service enrollment after the owner has approved the current intake: creates the client business and queues its package installations, which later configure the business's voice agent. Only the owner who started it can finish it. Repeating it returns the recorded agency_enrollment_owner_saveLets the client owner replace the intake facts on their own enrollment link. Requires the owner who claimed the link and the session's current revision. Saving clears any earlier owner approval, so the owner must approve again.agency_enrollment_createCreates an enrollment session for 1-50 existing or new clients against a published offer version and returns one owner approval link per new client. Requires an agency owner, admin or operator with access to each existing client, and an idempotency key; a replay returns the sessiagency_enrollment_saveReplaces the client entries of an uncommitted enrollment session. Requires the session creator (or an agency owner/admin) and the current session revision. Saving revokes all outstanding owner approval links for the batch, so owners must be sent new links.agency_enrollment_previewChecks every client in the batch for missing facts, owner approval and payer conflicts, and returns what enrolling would install, with the fingerprint and approval IDs needed to enroll. Requires an agency owner, admin or operator. It records the preview on the session but installagency_enrollment_enrollCommits the previewed batch: creates new client businesses, records owner approvals and queues package installations for every ready client; installations later configure each client voice agent. Requires an agency owner, admin or operator who created the session, its idempotencyagency_enrollment_claim_ownerLinks the signed-in client owner to their enrollment link using its token. The user's verified email must match the owner email on the link. It approves nothing.agency_enrollment_approve_ownerRecords the client owner's approval of the exact offer and intake facts on their enrollment link. Requires the owner who claimed the link, the session's current revision and its fingerprint.

Requires the session creator (or an agency owner/admin) and the link's current revision.
