Echoes back the provided message.
AI agents call echo to retrieve information from Dynamic Per-User Tool Generation MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The echo tool merely returns user-provided input without querying data, modifying state, executing code, or triggering external actions. This is a benign utility function with negligible security risk.
From the tool's definition Tool name 'echo' and description 'Echoes back the provided message' indicate a simple reflection of input with no side effects, data retrieval, or external operations.
Attacks that exploit this kind of access
Echoes back the provided message. It is categorised as a Read tool in the Dynamic Per-User Tool Generation MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Dynamic Per-User Tool Generation MCP Server MCP server in PolicyLayer and add a rule for echo: 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 Dynamic Per-User Tool Generation MCP Server. Nothing to install.
echo 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 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. 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.
echo is provided by the Dynamic Per-User Tool Generation MCP Server MCP server (shivampansuriya/mcp-server-python). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
