WHAT IT DOES

What call_destination does on Sap Btp Destination

AI agents invoke call_destination to trigger actions in Sap Btp Destination. 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.

RISK

Why call_destination is rated High

This tool executes outbound HTTP requests to external/backend systems using resolved authentication tokens from SAP BTP destinations. It is not merely reading configuration — it performs live calls to target URLs with auth tokens, which can trigger arbitrary operations (data reads, writes, transactions, etc.) depending on the destination.

From the tool's definition 'Call the target URL of a resolved destination using its auth token' — actively triggers an HTTP call to an external system using authenticated credentials

RECOMMENDED RULE

The rule that runs call_destination safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Sap Btp Destination, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For call_destination, this is the rule to start with:

call_destination Rate-limited

call_destination 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.

How do I enforce a policy on call_destination? +

Register the Sap Btp Destination MCP server in PolicyLayer and add a rule for call_destination: 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 Sap Btp Destination. Nothing to install.

What risk level is call_destination? +

call_destination is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit call_destination? +

Yes. Add a rate_limit block to the call_destination 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.

How do I block call_destination completely? +
