What is MCP?
MCP, or Model Context Protocol, is an open standard that lets AI applications connect to outside tools, data sources, and services in a consistent way. An MCP server exposes capabilities, and an AI client can discover and use them.

How MCP works
An MCP server wraps a tool or data source, such as a database or an analytics platform, and describes what it can do. An AI application acts as the client and can call those capabilities when a task needs them.
Because the standard is shared, one connector can work with many different AI applications.
Why it matters for marketing teams
MCP makes it easier for an AI assistant to work with the data and tools a team already uses, such as reporting, advertising, or content systems. That can let an assistant pull live information instead of relying on pasted copies.
Connecting an AI to business systems also raises questions about access and safety.
Security considerations
Grant each connection only the permissions it needs, prefer read-only access where possible, and review what the AI can change. Use connectors from sources you trust. Treat content that comes back through a connector as untrusted, since text in a document or web page can try to steer the AI into actions you didn't intend.
Common questions
What does MCP stand for?
MCP stands for Model Context Protocol. It's a standard way for AI applications to talk to external tools and data.
Is MCP the same as an API?
No. An API is how software exposes functions to other programs. MCP is a standard layer that describes tools in a way AI applications can discover and use, and it often sits on top of existing APIs.
Do you need to be a developer to use MCP?
Setting up a server usually takes some technical skill. Using an existing connector inside an AI application is often much simpler.
Is MCP safe?
It can be, with care. Limit permissions, use trusted connectors, and require approval for actions that change data or spend money.
