ContactZapp
Keeps your contacts in sync across Google, Microsoft, Apple and CardDAV, and cleans up duplicates.
What it does

No capability identified yet from its description.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

10 tools offered to AI assistants
getV1Me· Checks an API key. Returns the user the key acts for, the user's plan and the key's scopes. Any live key may call it, so it is the call to make when you want to test a key. Send the key in every request as `Authorization: Bearer <key>`. EaclistV1Contacts· Finds the user's contacts, or lists them. Give at most one of `email`, `phone` and `query`: - `email` and `phone` find the contacts that hold that address or number. An email is compared ignoring case, and a phone number ignoring formattingcreateV1Contact· Creates a contact. It is treated like a contact that arrives from a sync. The contact is written to one of the user's two-way accounts, which ContactZapp chooses: the earliest-linked account that keeps an address book and is not paused. ThegetV1Contact· Returns one contact. `id` is the contact's `id` or its `publicId` (`CS-0042`). A deleted or merged contact is a 404, and so is another user's contact.updateV1Contact· Changes a contact's fields, as the app's edit does. Only the fields in the body change; a field the body leaves out keeps its value. The change is recorded in History as the user's, naming the API key, and written to every two-way account tpostV1Sync· Starts a sync, the same as pressing Sync now in ContactZapp. The run shows in History as a manual run. The answer is 202 with the state of the sync: `queued` or `running`. If a sync is already going, you get that one back and no second onelistV1Accounts· Lists the user's linked accounts, as the Settings screen does: provider, name, sync direction, connection state and when each account last synced.listV1TriggerEvents· Polling trigger: returns the newest events of one type first. This is what Zapier, Make and n8n poll to start an automation. Each item has an `id` that never changes. Polling again with nothing new returns the same ids, and a new event appelistV1Webhooks· Lists the webhook subscriptions of this API key's user, oldest first: the URL, the event and whether it is `active` or `disabled`. The signing secret is never shown again after the subscription is made. Needs the `webhooks:manage` scope.createV1Webhook· Subscribes a URL to one event. Zapier, Make and n8n call this when an automation is switched on. The URL must use HTTPS and reach a public address. The answer is 201 with the subscription and its signing `secret`, which is shown only here.
What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
