Why create-link-preview needs a policy

The 'create-' prefix strongly implies a Write operation that creates a new resource. In Notion's context, a link preview is a type of block or embeddable content that can be inserted into pages. Since the description is empty, the exact behavior is unclear, but based on naming conventions and sibling tools (create-comment, create-page), this most likely creates a link preview block or object.

From the tool's definition Tool name 'create-link-preview' suggests creation of a new resource (a link preview) in Notion. Description is empty and uninformative, lowering confidence.

How to control create-link-preview

PolicyLayer is an MCP gateway — it sits between your AI agents and Notion MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create-link-preview:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "create-link-preview": {
      "limits": [
        {
          "counter": "create-link-preview_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create-link-preview stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Notion MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
