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

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

    "name": "sync_collection_with_schema",
    "arguments": {}

## Why sync_collection_with_schema is rated Medium

Syncing a collection with its schema is a write operation that modifies the collection's structure and contents to align with the schema definition. This is reversible in principle (the collection could be restored), but the sync may overwrite existing customizations or changes in the collection, making it potentially destructive in impact.

From the tool's own definition: "'Sync a collection with its schema' — synchronization overwrites/updates collection contents to match the schema"

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "sync_collection_with_schema": {
      "limits": [
        {

          "window": "minute",
          "max": 30,
