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

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

## Why oe_collections_db_init is rated Medium

This tool creates/initializes a local SQLite database file. While creation is reversible (the file can be deleted), it modifies the local filesystem state and establishes persistent data storage. This qualifies as Write rather than Destructive because initialization is not inherently destructive, and it's marked idempotent (safe to re-run).

From the tool's own definition: "Tool description states 'Create the local SQLite mirror' and 'Idempotent', indicating it creates or initializes a database file."

## Use case

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