Echo the input text
AI agents call echo_tool to retrieve information from Reservation Platform MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs no data retrieval, modification, deletion, code execution, or financial operations. It is a simple reflection/echo utility with no impact on system state or data. Classified as Read (benign query-like operation) with low severity due to minimal blast radius.
From the tool's definition Tool name is 'echo_tool' with description 'Echo the input text' — it returns input without modification or side effects.

Register the Reservation Platform MCP Server MCP server in PolicyLayer and add a rule for echo_tool: 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 Reservation Platform MCP Server. Nothing to install.
echo_tool 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 echo_tool 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 echo_tool. 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.
