List all user credential (basic auth) aliases configured in SAP CPI.
AI agents call list_credentials to retrieve information from Mcp Sap Cpi without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves credential metadata (aliases and configurations) from SAP CPI. While it is a Read operation that queries data without side effects, the severity is elevated to 'high' because it exposes credential information in a security-critical system (SAP enterprise integration).
From the tool's definition Tool description states 'List all user credential (basic auth) aliases configured in SAP CPI' — a retrieval operation that queries existing credentials without modifying them.

List all user credential (basic auth) aliases configured in SAP CPI. It is categorised as a Read tool in the Mcp Sap Cpi MCP Server, which means it retrieves data without modifying state.
Register the Mcp Sap Cpi MCP server in PolicyLayer and add a rule for list_credentials: 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 Cpi. Nothing to install.
list_credentials 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 list_credentials 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 list_credentials. 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.
list_credentials is provided by the Mcp Sap Cpi MCP server (keelside/mcp-sap-cpi). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
