AI agents call GetFunctionGroup to retrieve information from MCP ABAP ADT without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves source code artifacts from a SAP ABAP system without executing code, modifying data, or triggering side effects. It is a query operation with read-only semantics, consistent with development artifact inspection. The blast radius of misuse is minimal—an agent could retrieve sensitive source code but cannot modify systems or execute operations.
From the tool's definition Tool name 'GetFunctionGroup' and description 'Retrieve ABAP Function Group source code' indicate a retrieval operation with no modification capability.
Documented attack patterns abuse exactly the kind of access GetFunctionGroup gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP ABAP ADT, and nothing reaches the server without passing your rules. This is the rule we recommend for GetFunctionGroup:
{
"version": "1",
"default": "deny",
"tools": {
"GetFunctionGroup": {}
}
}GetFunctionGroup is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Retrieve ABAP Function Group source code. It is categorised as a Read tool in the MCP ABAP ADT MCP Server, which means it retrieves data without modifying state.
Register the MCP ABAP ADT MCP server in PolicyLayer and add a rule for GetFunctionGroup: 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 ABAP ADT. Nothing to install.
GetFunctionGroup is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the GetFunctionGroup 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 GetFunctionGroup. 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.
GetFunctionGroup is provided by the MCP ABAP ADT MCP server (mario-andreschak/mcp-abap-adt). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP ABAP ADT, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
