- Homepage: https://github.com/minhoyoo-iotrust/WAIaaS

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

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

## Why set_agent_uri is rated Medium

This is a Write operation because it updates data (agent registration URI) in a reversible manner. Severity is medium because while it doesn't directly move funds or execute arbitrary code, modifying agent registration in an identity registry could affect how agents are identified or authenticated in the system, potentially enabling impersonation or routing attacks if an AI agent sets a malicious URI pointing to…

From the tool's own definition: "'Update agent registration file URI on Identity Registry' indicates the tool modifies an existing registration record by changing its URI reference."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "set_agent_uri": {
      "limits": [
        {

          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
