 ### 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`).
+- 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`).
 - Built-in help tool: A static helper (`apify-actor-help-tool`) that returns usage info for the Apify MCP Server.
