## Facts

- Tool: `createWebhook`
- Server: Spline MCP Server (`aydinfer/spline-mcp-server`) — https://policylayer.com/tools/aydinfer-spline-mcp-server.md
- Homepage: https://github.com/aydinfer/spline-mcp-server
- Risk category: Write (Medium 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": "createWebhook",
    "arguments": {}
  }
}
```

## Why createWebhook is rated Medium

Webhooks are reversible integrations that can be deleted or modified later. The tool creates new webhook configurations rather than executing arbitrary operations or deleting data. Without a description, confidence is moderate, but the 'create' prefix and webhook nature suggest a Write category.

From the tool's own definition: "Tool named 'createWebhook' with empty description. Based on naming convention, this tool creates a webhook (a Write operation that establishes a new configuration/integration)."

## Use case

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

## Recommended policy (PolicyLayer)

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

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

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
