Agent View of the PolicyLayer registry record for `run`. HTML page: https://policylayer.com/tools/io-github-dave-london-pare-search/run

## Facts

- Tool: `run`
- Server: Search (`Dave-London/Pare`) — https://policylayer.com/tools/io-github-dave-london-pare-search.md
- Homepage: https://github.com/Dave-London/Pare
- Risk category: Execute (High risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

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

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

## Why run is rated High

The tool executes scripts or files, which can trigger arbitrary side effects depending on the script content and arguments provided. This falls under Execute rather than Write because it triggers external operations whose effects are not confined to data creation/modification. Severity is high because script execution has broad blast radius—an AI agent could inadvertently run malicious or unintended scripts.

From the tool's own definition: "Tool name 'run' combined with description 'Runs a script or file with' indicates execution of arbitrary code/scripts."

## Use case

AI agents invoke run to trigger actions in Search. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "run": {
      "limits": [
        {
          "counter": "run_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
