Agents Overview

How AI agents work with Datum Cloud — Skills, MCP, llms.txt, and datumctl.

Datum is built for agents as first-class users. Rather than wrapping an API in a chat interface, Datum exposes the same primitives humans use — YAML manifests, datumctl commands, and CRD-based resources — in ways that agents can reason about reliably. This section covers the four surfaces agents use to work with Datum: Skills (procedural know-how), Datum MCP (live API access), llms.txt (doc index), and datumctl (the CLI agents drive directly).

The four agent surfaces

Skills

Self-contained instructions agents load on demand. One skill per Datum resource — install once, agents handle the rest.

Datum MCP

The official Model Context Protocol server. Gives agents authenticated, live access to Datum APIs.

llms.txt

A single index file at datum.net/docs/llms.txt that agents fetch to discover the full documentation surface.

datumctl

The CLI. Agents invoke it directly for any platform action — same surface humans use.

Which one should I use?

If your agent needs to…	Use
Know how to do a Datum task (e.g. attach a domain to an HTTPProxy)	Skills
Read or write live Datum resources during a task	Datum MCP
Discover what documentation exists	llms.txt
Execute commands directly	datumctl

These surfaces layer together. A typical agent session loads one or two relevant Skills at startup, calls datumctl or Datum MCP to act, and falls back to llms.txt when it needs deeper context. See Skills to get started.
