Echo the input text
AI agents call echo_tool to retrieve information from MCP Wikipedia Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool has no side effects and performs no meaningful operation beyond reflecting user input. It does not access, modify, delete, or execute anything. While it is part of a Wikipedia server, it does not interact with Wikipedia functionality. The lowest severity classification (Read) is appropriate as it performs a trivial, non-destructive operation with minimal blast radius if misused.
From the tool's definition Tool named 'echo_tool' with description 'Echo the input text' - performs no data retrieval, modification, or external action; merely reflects input back to caller.
Attacks that exploit this kind of access
Echo the input text. It is categorised as a Read tool in the MCP Wikipedia Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Wikipedia 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 MCP Wikipedia 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.
echo_tool is provided by the MCP Wikipedia Server MCP server (kaman05010/mcpclientserver). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
