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

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

## Why update_agent is rated Medium

This tool modifies existing agent data/configuration, which is a Write operation. Severity is high because unauthorized agent updates could redirect agent behavior, modify permissions, or compromise agent integrity in a multi-agent system. Confidence is 0.85 (not higher) because the description lacks specificity about what aspects of an agent can be updated and what side effects might occur.

From the tool's own definition: "Tool name 'update_agent' and description 'Update an agent' indicate modification of agent configuration or state. The action is reversible (update, not delete) and operates on agent resources within the control plane."

## Use case

AI agents use update_agent to create or update resources in ProAgentStore, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ProAgentStore environment.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "update_agent": {
      "limits": [
        {
          "counter": "update_agent_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
