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

```json
{
  "jsonrpc": "2.0",

  "params": {

## Why verify_audit_chain is rated Low

Despite the empty description lowering confidence slightly, the naming pattern and context strongly indicate this tool checks or validates audit chain integrity—a read operation with no data modification or side effects. It fits the pattern of trust/identity infrastructure verification tools that query and validate rather than modify state.

From the tool's own definition: "Tool name 'verify_audit_chain' suggests verification/checking of existing audit data. Sibling tools on this server (check_avp_reputation, check_trust, get_audit_trail) are all read operations."

## Use case

AI agents call verify_audit_chain to retrieve information from AgentVeil Protocol 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 AgentVeil Protocol:

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