Read and manage Google Contacts via the Google People API: connections, contacts and contact groups.
Google Contacts ships in the w6w first-party pack. It declares 14 actions, 2 health checks, and the host runs its code in a sandbox that never sees the credential.
io.w6w.google-contactsGoogle Contacts manages the people in a Google account’s address book, and this app reads and writes them through Google’s current People API. List a user’s connections, look up or search for a specific contact, and create, update or delete one — plus create, update, delete and manage membership of contact groups, including built-in ones like “starred”.
Updates follow Google’s required read-then-write pattern: fetch a contact for its etag, then send changes back with that etag attached, so two writers can’t silently overwrite each other’s edits. Field masks — which fields to fetch or write — are required by the API on nearly every call, and this app ships working defaults so a workflow author doesn’t have to learn Google’s parameter-naming quirks per action.
A fit for syncing contacts into or out of a CRM, keeping a mailing list’s groups current from another system, or looking up a person’s details before drafting an outbound message.
Three routes to the same 14 actions. The Workflow tab is generated from Google Contacts's own manifest and carries its real ids, so it is copy-pasteable; the Code and CLI examples are the same call for any action on any app, so every app-specific value in them is a blank you fill in.
create-contact-group Create a new contact group (label). Names must be unique for the user.
delete-contact-group Delete a user contact group, optionally deleting the contacts inside it.
get-contact-group Read a single contact group, optionally including its member resource names.
get-person Read a single contact or profile by resource name. Use `people/me` for the authenticated user.
list-connections List the authenticated user's contacts (connections), one page at a time.
list-contact-groups List the authenticated user's contact groups (labels), system and user-made.
list-other-contacts List 'Other contacts' — addresses Google collected automatically that were never saved as contacts.
modify-contact-group-members Add contacts to, or remove contacts from, a contact group.
search-contacts Search the authenticated user's contacts by name, nickname, email, phone number or organization.
update-contact Update fields on an existing contact. Requires the etag read with the contact.
A workflow step names the app and the action, and the editor fills in the
connection when you pick one. This is the Step shape from the
workflow spec, carrying Google Contacts's real ids.

Every app-specific value here is a blank you have to fill in. An
app action is reached through the connection that authenticates it, so the
address is a connection id, not the app id — and connections belong to your account,
so a public page cannot know yours. Create one for Google Contacts, then fill in
the three blanks: conn_YOUR_CONNECTION_ID, the action key, and the
parameters that action declares. The call itself is real — the shape is transcribed
from the studio's own snippet builder, which prints the same kind of blanks — but
nothing in it is specific to Google Contacts. The Workflow tab is where this app's
real ids are.

One MCP endpoint exposes every app, function and workflow the caller is entitled to, as tools it can discover and run. Access is granted per team while we onboard.
One tool call{
"name": "w6w_invoke",
"arguments": {
"ref": "app:io.w6w.google-contacts#batch-get-people",
"input": {
"resourceNames": "<resourceNames>",
"personFields": "<personFields>"
}
}
}
Every tool names its target with a single ref. The
app: form above doesn't name a connection at all — the
host resolves which of the caller's Google Contacts connections to sign
with, and refuses rather than guesses when the answer is ambiguous.
The token is attached host-side, at the moment of the call. It is never a tool argument, never in the model's context, and never in a transcript — so a prompt injection has nothing to exfiltrate.
Tools are derived per end user from what that person has actually connected and is entitled to — not one shared bot identity carrying the union of everyone's access.
Multi-step work runs on the workflow engine and returns a run handle the agent can poll — retries, branching and state survive the conversation that started them.
Google Contacts's declared health checks are on the surface too, so an agent can tell "the vendor is down" from "your credential expired" before it burns a retry on either.
The MCP surface is part of the hosted platform. Google Contacts itself is MIT, and the runtime that executes it is source-available (FSL).
Google Contacts declares its own checks, so its health is a property of the app rather than something the host guesses at.
