Available Tool Categories
The MCP server exposes 116 tools across 11 resource categories. Each category has a dedicated reference page listing every tool, its parameters, permission, and return shape.Phone numbers are not yet generally available, so the 2 tools in that
category are advertised only to organizations with phone enabled. Every
other category is always available. The contact phone-number tools under
Contacts are unaffected.
Permission Model
Each tool requires specific permissions to execute. Permissions follow the patternresource:action (e.g., contacts:read) or
resource.subresource:action for nested resources (e.g.,
contacts.emails:write).
Permission levels:
Examples:
contacts:read- List and view contactscontacts:write- Create and update contactscontacts.emails:write- Add or update contact email addressesmessages:read- View and search messages
You grant these permissions on the MCP server’s consent screen during the
OAuth handshake. The set of tools advertised over
tools/list is filtered
against the categories you approve. See
