Concrete capability record
Data, retrieval, actions, identity, and operating limits
A field-by-field summary of what the reviewed first-party references actually support. Publisher update dates and BYO-UI review dates are shown separately below.
02 · Data you can retrieve
Inspect content and contact data, data-extension schemas and rows, journey and automation configuration, message assets, engagement results, dependencies, and status across the connected organization.
03 · Actions and write paths
Create or update content, data extensions and rows, journeys, automations, and messages; sequence multi-step workflows; and perform permitted destructive or send operations through wrapped Marketing Cloud APIs.
04 · Authentication and permissions
A dedicated installed package produces an organization- and package-specific MCP URL. The client uses Marketing Cloud OAuth, and effective access is the intersection of package scopes and the authenticated user's permissions.
05 · Monitoring, approval, and recovery
Grant only required package scopes, review agent output for accuracy, and use dry runs or planned-code previews for destructive tools. Require explicit confirmation before deletion, broad data-extension updates, journey activation, or any send.
06 · Limits and caveats
Marketing Cloud API limits still apply. Some tools are asynchronous and require status polling, open-world data extensions have variable schemas, and destructive annotations warn the agent but do not prevent execution when permissions allow it.

MCP support
Official MCP serverSalesforce-hosted Marketing Cloud Engagement MCPGeneral availability since June 2026
Support: Official MCP server
Read scope: Read content, contacts, data extensions, journeys, automations, messages, engagement results, dependencies, and operational status allowed by package and user permissions.
Write scope: Create or modify supported content, data extensions, rows, journeys, automations, and messages; permitted tools can also delete data or trigger sends.
Authentication: Marketing Cloud OAuth through an organization- and installed-package-specific hosted MCP URL, yielding a limited-lived token for the signed-in user.
Approval boundary: Preview the organization, business context, object identifiers, dependency impact, and planned tool sequence; require explicit approval before destructive changes, journey activation, transactional messaging, or broad row updates.
Protocol does not erase product boundaries.
Confirm the current tool catalog, plan, region, scopes, rate limits, terms, and write behavior before implementation.
