Click a column header in an ALV grid (triggers sort). Does NOT work on GuiTableControl.
AI agents invoke sap_press_column_header 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.
This tool performs a click action on a UI element that triggers an operation (sorting) in the SAP GUI. It is an interactive action that causes side effects in the SAP application state, classifying it as Execute. Severity is medium because misuse could disrupt data views or trigger unintended SAP GUI behaviors, but it is limited to sorting operations.

Documented attack patterns abuse exactly the kind of access sap_press_column_header gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP SAP GUI Server, and nothing reaches the server without passing your rules. This is the rule we recommend for sap_press_column_header:
{
"version": "1",
"default": "deny",
"tools": {
"sap_press_column_header": {
"limits": [
{
"counter": "sap_press_column_header_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
} sap_press_column_header 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.

Click a column header in an ALV grid (triggers sort). Does NOT work on GuiTableControl. It is categorised as a Execute tool in the MCP SAP GUI Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the MCP SAP GUI Server MCP server in PolicyLayer and add a rule for sap_press_column_header: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP SAP GUI Server. Nothing to install.
sap_press_column_header is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the sap_press_column_header rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for sap_press_column_header. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
sap_press_column_header is provided by the MCP SAP GUI Server MCP server (kts982/mcp-sap-gui). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP SAP GUI Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
