What is MCP (Model Context Protocol)?
MCP is an open standard for connecting AI agents to tools and data through a common interface — so any agent can use any compatible tool without custom glue.
MCP — the Model Context Protocol — is an open standard for connecting AI agents to tools and data through a common interface. Instead of writing bespoke glue for every integration, an agent speaks one protocol, and any MCP-compatible tool or server becomes available to it.
The problem MCP solves
Agents are only as capable as the tools they can reach. Before a standard, every connection — a CRM, a database, a SaaS API — was a custom integration to build and maintain. MCP turns that into a plug: tools expose themselves as MCP servers, and agents discover and call them through the same interface. Capabilities compose instead of multiplying into glue code.
What it means in practice
With MCP, an agent's toolset becomes modular. You can give an agent access to a payments server, a messaging server, and your own data — each behind the same protocol — and add or remove capabilities without rewriting the agent.
MCP and governance
A protocol defines how things connect, not whether they should. In an enterprise setting the controls live in the runtime: which agent is allowed to call which MCP server, credentials that are short-lived and scoped per call, and a log of every invocation. That separation — open connectivity, enforced control — is the same principle behind a well-run agentic app, and is covered in the enterprise AI agents guide.
Frequently asked questions
What does MCP stand for?
MCP stands for Model Context Protocol — an open standard for how AI models and agents connect to external tools and data sources through a consistent interface.
Why does MCP matter for AI agents?
It removes custom integration glue. Instead of hand-coding every connection, an agent speaks one protocol and can use any MCP-compatible tool or server — so capabilities compose and integrations are reusable.
Is MCP secure for enterprise use?
MCP defines the interface; security comes from how you run it — scoping which agent may call which MCP server, using short-lived credentials, and logging every call. The protocol enables connectivity; the runtime enforces the controls.
