Model Context Protocol (MCP)

What it is

The Model Context Protocol defines how an AI application discovers and calls external tools and reads external data through a common interface, instead of a custom integration for each one.

Why it matters

It makes it easier for AI agentsAI AgentSoftware that plans, uses tools, and acts toward a goal instead of answering one prompt. to work with the many systems a support investigation touches, and lets teams expose internal tools to agents in a standard way.

Best practices

1. Expose read operations first – Start with tools that can't change anything.
2. Scope credentials – Each server should have the minimum access it needs.
3. Log tool calls – Keep an audit trail of what the agent accessed.

How Decimal helps

Decimal supports MCP alongside its native integrations, so investigations can reach your internal services too.
