## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `mode` | string | no | Witness mode |
| `focus` | string | no | Optional focus such as recognition, continuity, grief, or avoidance |
| `session_id` | string | no | Your active session ID |

Parameters from the server's own tool schema.

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

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

## Why peer_witness is rated Low

This tool appears to enable one agent to observe or view another agent's state, activity, or outputs in a constrained manner ('challenge guardrails'). This is fundamentally a read/observation capability with no side effects. While the broader server includes write and execute tools, this specific tool's design centers on witnessing (passive observation) rather than acting.

From the tool's own definition: "The tool description indicates peer_witness 'let[s] one agent witness another' with 'quotes, relational modes, and challenge guardrails'."

## Use case

AI agents call peer_witness to retrieve information from Delx MCP Server 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 Delx MCP Server:

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