echo

What echo does on ContextForge MCP Gateway

AI agents call echo to retrieve information from ContextForge MCP Gateway without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why echo is rated Low

An echo tool merely returns the input provided to it, making it a read-only operation with no side effects, data modification, or external execution. The lack of an output schema reinforces that this is a simple passthrough utility. Risk is minimal unless the tool could be abused to infer information about the system, but as a basic reflection mechanism, it represents the lowest risk category.

From the tool's definition Tool is named 'echo' and described as 'Simple echo tool without output schema'. Echo tools reflect input back without side effects, modification of state, or execution of external operations.

The rule that runs echo safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ContextForge MCP Gateway, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For echo, this is the rule to start with:

{
  "version": "1",
  "default": "deny",
  "tools": {
    "echo": {}
  }
}
