Register the Agentic AI System with MCP Integration MCP server in PolicyLayer and add a rule for query_transactions: 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 Agentic AI System with MCP Integration. Nothing to install.
query_transactions 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 query_transactions 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 query_transactions. 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.
query_transactions is provided by the Agentic AI System with MCP Integration MCP server (pratyush-usc-mba/designing-an-agentic-ai-system-with-mcp-integration). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
