- Install: `npx -y nodebench-mcp`
- Homepage: https://github.com/HomenShum/nodebench-ai
- Risk category: Write (Medium risk)

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

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

## Why link_durable_objects is rated Medium

The tool creates persistent relationships/links between entities. This is a write operation that modifies data by establishing durable associations. It is reversible in principle (links can typically be removed), so it does not qualify as Destructive. Severity is medium as misuse could create incorrect or misleading relationships between workflow artifacts.

From the tool's own definition: "Create a durable relationship such as screen -> action, workflow -> run, run -> artifact, or outcome -> evidence."

## Use case

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

## Recommended policy (PolicyLayer)

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

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

          "scope": "grant"
        }
