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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "s3_read_object",
    "arguments": {}
  }
}
```

## Why s3_read_object is rated Low

This tool retrieves data from cloud storage (AWS S3). While it performs no destructive or reversible modifications, the severity is elevated to 'high' because S3 buckets often contain sensitive data, credentials, or PII. Unauthorized reads can cause significant information disclosure. The empty description lowers confidence slightly, but the explicit 'read' terminology in the name provides strong categorical signal.

From the tool's own definition: "Tool name 's3_read_object' indicates retrieval of objects from Amazon S3; 'read' explicitly signals a query/retrieval operation with no mutation."

## Use case

AI agents call s3_read_object to retrieve information from Integrations MCP 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 Integrations MCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "s3_read_object": {}
  }
}
```
