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

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

## Why seal_artifact is rated Medium

Sealing creates a new certified artifact envelope and a registry entry, which are write operations. However, sealing typically implies locking/finalizing an artifact making it immutable, which could have irreversible consequences.

From the tool's own definition: "Seal an EDM artifact via DeepaData API, creating a certified .ddna envelope with registry entry"

## Use case

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

## Recommended policy (PolicyLayer)

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

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