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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "ruvector_create_index",
    "arguments": {}
  }
}
```

## Why ruvector_create_index is rated Medium

This tool creates (writes) a vector index artifact for search optimization. While it modifies system state by adding an index, the operation is reversible—indices can be deleted or recreated without permanent data loss. It does not execute arbitrary code, delete irreversibly, or move money. Classified as Write rather than Execute because it is a specific data structure creation, not arbitrary code execution.

From the tool's own definition: "Tool name 'ruvector_create_index' and description 'Create a vector index' indicate creation of a new data structure. The description explicitly states the action is to 'Create' an index, which is a reversible modification operation."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
