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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "superdoc_close",
    "arguments": {
      "session_id": "<session_id>"
    }
  }
}

## Why superdoc_close is rated Medium

While closing a session could be considered a destructive action in some contexts, the evidence that unsaved changes are explicitly discarded suggests this is a controlled session-termination operation rather than data deletion. The user can reopen the document afterward. However, it crosses into Write territory because it modifies the application state (session status) irreversibly within the current workflow.

From the tool's own definition: "Tool name 'superdoc_close' combined with description stating 'Unsaved changes will be lost' indicates it closes/terminates a document session."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json

  "tools": {
    "superdoc_close": {
      "limits": [
        {
