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

```json
{
  "jsonrpc": "2.0",

## Why notion_action is rated Medium

The tool performs read operations (search, read) which would normally be 'Read' category, but the explicit mention of 'update' capability elevates this to 'Write' since it can create or modify data reversibly.

From the tool's own definition: "Tool description states it can 'search, read, and update pages/data sources' in Notion. The 'update' capability indicates modification of data."

## Use case

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

## Recommended policy (PolicyLayer)

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

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