## Facts

- Tool: `echo`
- Server: OpenClaw (`openclaw`) — https://policylayer.com/tools/openclaw.md
- Install: `npx -y openclaw`
- Homepage: https://www.npmjs.com/package/openclaw
- Risk category: Read (Low risk)
- Registry record: grade F, identity verified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "echo",
    "arguments": {}
  }
}
```

## Why echo is rated Low

An echo tool merely returns the input it receives. It does not read from external sources, write data, execute commands, or perform any destructive or financial actions. It is essentially a no-op passthrough, making it very low risk.

From the tool's own definition: "Echo input text — simply reflects input back, no side effects, no data modification or retrieval from external systems."

## Use case

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

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches OpenClaw:

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

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
