 ### Helper tools
 One of the powerful features of MCP with Apify is dynamic actor tooling – the ability for an AI agent to find new tools (Actors) as needed and incorporate them. Here are some special MCP operations and how Apify MCP Server supports them:
 
-- Actor discovery and management: Search for Actors (`search-actors`), view details (`get-actor-details`), and dynamically add or remove tools (`add-actor`, `remove-actor`).
-- Actor execution and monitoring: Start Actor runs, fetch run results (`get-actor-run`), logs (`get-actor-log`), and abort runs (`abort-actor-run`).
-- Dataset access: List datasets, retrieve dataset info and items (`get-dataset`, `get-dataset-list`, `get-dataset-items`).
-- Key-value store access: List key-value stores, view keys, and retrieve records (`get-key-value-store-list`, `get-key-value-store`, `get-key-value-store-keys`, `get-key-value-store-record`).
-- Built-in help tool: A static helper (`apify-actor-help-tool`) that returns usage info for the Apify MCP Server.
+- Actor discovery and management: Search for Actors (`search-actors`), view details (`get-actor-details`), and dynamically add them (`add-actor`).
+- Apify documentation: Search Apify documentation (`search-apify-docs`) and fetch specific documents (`fetch-apify-docs`).
+- Actor runs (*): Get a list of your Actor runs (`get-actor-run-list`), specific run details (`get-actor-run`), and logs from a specific Actor run (`get-actor-log`).
+- Apify storage (*): Access datasets (`get-dataset`, `get-dataset-items`, `get-dataset-list`), key-value stores (`get-key-value-store`, `get-key-value-store-keys`, `get-key-value-store-record`, `get-key-value-store-records`), and their records.
+
+Note: Helper tool categories marked with (*) are not enabled by default in the MCP server and must be explicitly enabled using the `?tools` URL query parameter. The `tools` parameter is a comma-separated list of categories with the following possible values:
+
+- `docs`: Search and fetch Apify documentation tools.
+- `runs`: Get Actor runs list, run details, and logs from a specific Actor run.
+- `storage`: Access datasets, key-value stores, and their records.
+- `preview`: Experimental tools in preview mode.
+
+For example, to enable all tools, use `https://actors-mcp-server.apify.actor/?tools=docs,runs,storage,preview`.
