Why agents stall at SAP

An agent that reads public documents is easy to deploy. The trouble starts when it has to read an order or create a purchase requisition in SAP. The questions that follow are about security and control: who is calling, with which rights, how often, and who approves the change.

A well-run integration layer already answers those questions for applications and partners. Agent-ready means answering them for agents too, before the first call, in the layer and not in the prompt.

The gateway as the single entry point

An MCP gateway in SAP Integration Suite exposes SAP capabilities as tools. Each tool maps to a managed API, a narrow scope and a rate limit, so the agent never talks to a backend directly.

The agent sees a list of tools. Everything behind them stays where it is: your managed APIs, your flows and your systems of record.

Ten checks in four groups

Who may call, and how often

Each tool maps to a narrow OAuth scope, so a tool that reads orders cannot be used to change them. A shared technical user hides who did what. Rate limits per agent and per tool, enforced in API Management, stop a looping agent from flooding a backend.

What the agent can understand

Agents choose tools from their descriptions, so each tool needs a plain-language purpose, its limits and an example. A JSON Schema for every input and output, validated at the gateway, rejects a malformed call before SAP is touched. Machine-readable errors with codes let the agent recover instead of guessing.

Writes that are safe to repeat and safe to approve

Agents retry. An idempotency key makes sure a retried write never posts twice. High-risk writes wait for a named approver, defined per tool and logged with the call, so low-risk reads stay fast.

Evidence and change

The audit trail records who called what, with which data, and what changed. One trace ID from the agent to SAP and back makes a single call easy to follow. A versioning policy lets a tool change without breaking the agents already using it.

The tool definition below carries most of the checks: the description, the schema, the read-only hint and a governance block with scope, rate limit and audit flag.

Where to start

Pick one interface you know well and score it against the ten checks. The gaps tell you what to build first. The self-assessment takes about ten minutes. If you want the same checks run across your landscape, that is our one-week assessment.
