sap_type · MCP SAP GUI Server MCP: Risk & Policy

WHAT IT DOES

What sap_type does on MCP SAP GUI Server

AI agents invoke sap_type to trigger actions in MCP SAP GUI Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why sap_type needs a policy

Typing text into an active SAP GUI session can modify fields, trigger validations, or initiate business processes depending on the current transaction context. Since SAP manages critical business data (financials, HR, supply chain), arbitrary text input into an active session is an Execute-level action with high blast radius — a misused input could corrupt records, trigger unwanted postings, or advance transactions…

From the tool's definition 'Type text at current cursor position' — triggers keyboard input into SAP GUI at whatever field/transaction is currently active, with effects entirely dependent on context and arguments

Verdict

sap_type Rate-limited

sap_type stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
