Simple echo tool for testing. Returns the input message back.
AI agents call echo to retrieve information from ProduckAI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a testing/diagnostic utility that reads an input and returns it unchanged. It performs no data access, modification, deletion, code execution, or financial operations. It is classified as Read because it responds to input without performing any meaningful operation, and represents the lowest risk profile—no blast radius if misused by an AI agent.
From the tool's definition Tool name 'echo' and description 'Simple echo tool for testing. Returns the input message back.' indicates a pure reflection mechanism with no side effects, data retrieval, or external state modification.
Attacks that exploit this kind of access
Simple echo tool for testing. Returns the input message back. It is categorised as a Read tool in the ProduckAI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ProduckAI 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 ProduckAI 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 ProduckAI MCP Server MCP server (rohitsaraff33-bit/produckai-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
