-The Apify Model Context Protocol (MCP) server allows AI agents and frameworks compatible with the MCP standard to connect with the extensive library of Actors available on [Apify Store](https://apify.com/store).
+The _Apify Model Context Protocol (MCP) Server_ allows AI applications to connect to Apify’s extensive library of Actors as tools to perform web scraping, data extraction, or other automation tasks in real time.
 
-## Why use MCP with Apify?
+![Apify MCP Server](./images/actors-mcp-server.webp)
 
-- _Access a vast tool library_: Provide AI agents access to thousands of pre-built Actors for web scraping, data extraction, and automation.
-- _Dynamic tool discovery_: Unlike static OpenAPI definitions, MCP enables agents to dynamically find and add relevant Actors to their context during runtime. Agents can use MCP operations like `discover-actors` and `add-actor-to-tools`.
-- _Scalability_: Efficiently manage access to a large and growing number of tools, which is challenging with single, static API definitions.
-- _Flexible integration_: Connect to the MCP server using HTTP Server-Sent Events (SSE) or local standard input/output (stdin/stdout). Compatible clients include Claude Desktop, LibreChat, and [Apify’s Tester MCP Client](https://apify.com/jiri.spilka/tester-mcp-client).
+## Quickstart
 
-## Common use cases
+You can use the Apify MCP Server in two ways:
+
+- Standard Input/Output (stdio): Ideal for local integrations and command-line tools such as the Claude desktop client.
+  - Set MCP client server command to `npx @apify/actors-mcp-server` and environment variable `APIFY_TOKEN` to your Apify API token
+  - See `npx @apify/actors-mcp-server --help` for more options
+- HTTPS Endpoint [mcp.apify.com](https://mcp.apify.com): Connect your MCP client by including `Authorization: Bearer <APIFY_TOKEN>` header in your requests.
+  - `https://mcp.apify.com` for streamable transport
+  - `https://mcp.apify.com/sse` for legacy SSE transport
+
+_(You could also use legacy option by running [Apify Actors MCP Server](https://apify.com/apify/actors-mcp-server) as Actor.)_
 
-- Extract data from websites, such as social media posts, search engine results, or specific URLs.
-- Summarize web content or identify trends.
-- Run automated web workflows without direct user interaction.
 
 ## Prerequisites
 
 Before you start, make sure you have the following:
 
-1. _Apify account_: You need an active account on the Apify platform.
-2. _API Token_: Get your personal API token from the **Integrations** section in [Apify Console](https://console.apify.com/account#/integrations).
+1. _An Apify account:_ Sign up for a free Apify account if you don’t have one.
+1. _Apify API Token:_ Get your personal API token from the **Integrations** section in [Apify Console](https://console.apify.com/account#/integrations). This token will be used to authorize the MCP server to run Actors on your behalf.
+1. _MCP client:_ You will also need an AI agent or client that supports MCP. This could be Anthropic Claude desktop, a VS Code extension with MCP support, Apify’s web-based Tester MCP Client, or any custom client implementation. See supported MCP clients in [official documentation](https://modelcontextprotocol.io/clients).
 
-## Connection methods
+## Example usage (local stdio with Claude desktop)
 
-Apify provides two main ways to connect your MCP client to Actors:
+Let’s walk through an example of using Claude desktop with the Apify MCP Server:
 
-1. Main Actors MCP Server: Access _all_ public Actors. Requires dynamic discovery or specifying Actors via URL parameters.
-2. Actor-specific MCP Server: A dedicated endpoint for a _single_ Actor, which is pre-registered and ready for immediate use.
+1. _Configure Claude desktop:_ Claude desktop supports MCP servers via the **Developer settings**. You need to add an entry for the Apify MCP server. For instance, in Claude’s config file, under `mcpServers`, add an entry like:
 
-### Option 1: Use the main Actors MCP server
+    ```json
+    {
+     "mcpServers": {
+       "actors-mcp-server": {
+         "command": "npx",
+         "args": ["-y", "@apify/actors-mcp-server"],
+         "env": {
+            "APIFY_TOKEN": "YOUR_APIFY_TOKEN"
+         }
+       }
+     }
+    }
+    ```
 
-This method offers the most flexibility, allowing access to all of Apify Store dynamically or by specifying Actors at connection time.
+    This tells Claude to spawn the Apify MCP Server (via the [Actors MCP Server](https://www.npmjs.com/package/@apify/actors-mcp-server) NPM package with your API token (on the first run, it will download the package automatically).
 
-```text title="Server endpoint"
-https://actors-mcp-server.apify.actor/sse?token=<YOUR_API_TOKEN>
-```
+1. _Launch Claude and connect:_ After updating the config, restart Claude desktop. If successful, Claude will show a “plugin” (often indicated by a plug icon 🔌) signifying it connected to the Apify Actors MCP server.
 
-Key features:
+1. _Use the Actors in conversation:_ You can chat with Claude and ask it to use Apify Actors. For example: _“What Apify Actors can I use?”_ Claude will list available tools via the MCP server. If none are pre-loaded, it may show defaults or guide you to find more.
 
-- Dynamic discovery: Agents can use MCP operations like `discover-actors` to search Apify Store for tools.
-- Dynamic registration: Agents can use the `add-actor-to-tools` operation to add discovered Actors to their available toolset for the current session.
-- Pre-registration via URL: You can make specific Actors available immediately by adding the `&actors=` query parameter to the connection URL (for example, `&actors=apify/rag-web-browser`).
+_(If you prefer not to set up Claude desktop, you can achieve a similar result using [Apify’s Tester MCP Client](https://apify.com/jiri.spilka/tester-mcp-client), which provides a web UI to test the MCP server.)_
 
-The following example demonstrates connecting to the main server while pre-registering the `apify/rag-web-browser` Actor.
+![Apify Tester MCP Client](./images/chat-ui.webp)
 
-#### Step 1: Start the SSE connection
+## Interact with the MCP Server over SSE
 
-Use `curl` or another SSE client to establish the connection. Append `&actors=apify/rag-web-browser` to pre-register the tool. Replace `<YOUR_API_TOKEN>` with your actual Apify API token.
+You can interact with the server through Server-Sent Events (SSE) to send messages and receive responses.
 
-```bash
-# Start the Server-Sent Events (SSE) session and keep it active
-curl "https://actors-mcp-server.apify.actor/sse?token=<YOUR_API_TOKEN>&actors=apify/rag-web-browser"
+In the client settings, you need to provide server configuration:
 
-# The server responds with the session endpoint. Note the sessionId.
-# event: endpoint
-# data: /message?sessionId=9d820491-38d4-4c7d-bb6a-3b7dc542f1fa
+```json
+{
+    "mcpServers": {
+        "apify": {
+            "type": "sse",
+            "url": "https://actors-mcp-server.apify.actor/sse",
+            "env": {
+                "APIFY_TOKEN": "your-apify-token"
+            }
+        }
+    }
+}
 ```
 
-#### Step 2: Send a tool call request
-
-Use the `sessionId` obtained in Step 1 to send a POST request to the `/message` endpoint. This request invokes the pre-registered `apify/rag-web-browser` tool. Replace `<YOUR_API_TOKEN>` and `<SESSION_ID>` with your actual values.
-
-```bash
-curl -X POST "https://actors-mcp-server.apify.actor/message?token=<YOUR_API_TOKEN>&session_id=<SESSION_ID>" \
--H "Content-Type: application/json" \
--d '{
-  "jsonrpc": "2.0",
-  "id": 1,
-  "method": "tools/call",
-  "params": {
-    "arguments": {
-      "query": "web browser for RAG pipelines -site:reddit.com",
-      "proxyConfiguration": {
-            "useApifyProxy": true
-      },
-      "removeElementsCssSelector": "nav, footer, script, style, noscript, svg, img[src^='\''data:'\''],\\n[role=\\"alert\\"],\\n[role=\\"banner\\"],\\n[role=\\"dialog\\"],\\n[role=\\"alertdialog\\"],\\n[role=\\"region\\"][aria-label*=\\"skip\\" i],\\n[aria-modal=\\"true\\"]",
-      "htmlTransformer": "none"
-    },
-    "name": "apify/rag-web-browser"
-  }
-}'
-
-# The server immediately confirms receipt of the request:
-# Accepted
-```
+## Adding Multiple Actors
 
-#### Step 3: Receive the result via SSE
+By default, the main Actors MCP Server starts with a single default [RAG Web Browser Actor](https://apify.com/apify/rag-web-browser). However, you can fully customize which Actors are available:
 
-The Actor's result is sent back asynchronously over the SSE connection established in Step 1.
+- **Dynamic adding during a session:** If your client supports it, the agent itself can add Actors dynamically by name (using the `add-actor` operation) at runtime. For example, after using `search-actors` to find an Actor’s name, calling `add-actor` with that name will load it. Note that not all MCP client frameworks allow dynamic tool addition at runtime, but Apify’s own tester client does, if `enableAddingActors` is enabled—either via `?enableAddingActors=true` in the MCP Server URL, or with the CLI flag `--enable-adding-actors` (can also be set in Claude Desktop config args as `--enable-adding-actors`).
+- **Via config file (for Claude desktop):** When using Claude desktop, you can specify which Actors should be immediately available by configuring your `mcpServers` settings. Add the Actors as a comma-separated list in the `--actors` parameter, as shown in the example below. This pre-loads your selected tools without requiring discovery during conversations, ideal for workflows with predictable tool needs.
 
 ```json
-event: message
-data: {
-  "result": {
-    "content": [
-      {
-        "type": "text",
-        "text": "[{\"searchResult\":{\"title\":\"... RAG Web Browser Result ...\",\"description\":\"... Content extracted by the Actor ...\"}}]" // Example structure
+   {
+    "mcpServers": {
+      "actors-mcp-server": {
+        "command": "npx",
+        "args": [
+          "-y", "@apify/actors-mcp-server",
+          "--actors", "lukaskrivka/google-maps-with-contact-details,apify/instagram-scraper"
+        ],
+        "env": {
+           "APIFY_TOKEN": "YOUR_APIFY_TOKEN"
+        }
       }
-    ]
-  }
-}
-```
-
-### Option 2: Use an Actor-specific MCP server
-
-Certain Actors, such as `apify/rag-web-browser`, offer their own dedicated MCP server endpoint. This simplifies integration when you only need to interact with that specific Actor.
-
-```text title="Endpoint example for &#96;apify/rag-web-browser&#96;"
-https://rag-web-browser.apify.actor/sse?token=<YOUR_API_TOKEN>
+    }
+   }
 ```
 
-:::note
-
-The hostname typically matches the Actor's name.
+In summary, you can start with a broad set (everything open and discoverable) or a narrow set (just what you need) and even expand tools on the fly, giving your agent a lot of flexibility without overwhelming it initially.
 
-:::
+## Dynamic Actor Tooling
 
-This method is ideal for integrating a specific tool directly into an application (like Claude Desktop) or a custom client without needing the dynamic discovery capabilities of the main server.
+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:
 
-The following example demonstrates use of `rag-web-browser` server.
+- _Actor discovery and management:_ Search for [Actors](https://docs.apify.com/platform/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](https://docs.apify.com/platform/actors/running/runs-and-builds#runs), fetch run results (`get-actor-run`), logs (`get-actor-log`), and abort runs (`abort-actor-run`).
+- _Dataset access:_ List [datasets](https://docs.apify.com/platform/storage/dataset), retrieve dataset info and items (`get-dataset`, `get-dataset-list`, `get-dataset-items`).
+- _Key-value store access:_ List [key-value stores](https://docs.apify.com/platform/storage/key-value-store), 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.
 
-#### Step 1: Start the SSE connection
-
-Connect directly to the Actor's specific MCP endpoint. Replace `<YOUR_API_TOKEN>` with your actual Apify API token.
-
-```bash
-# Start the Server-Sent Events (SSE) session and keep it active
-curl "https://rag-web-browser.apify.actor/sse?token=<YOUR_API_TOKEN>"
-
-# The server responds with the session endpoint. Note the sessionId.
-# event: endpoint
-# data: /message?sessionId=5b2a...
-```
-
-#### Step 2: Send a tool call request
-
-Use the `sessionId` from Step 1 to send a POST request to the Actor's `/message` endpoint. Replace `<YOUR_API_TOKEN>` and `<SESSION_ID>` with your actual values. The tool `name` in the parameters typically matches the Actor name.
-
-```bash
-curl -X POST "https://rag-web-browser.apify.actor/message?session_id=<SESSION_ID>&token=<YOUR_API_TOKEN>" \
--H "Content-Type: application/json" \
--d '{
-    "jsonrpc": "2.0",
-    "id": 1,
-    "method": "tools/call",
-    "params": {
-      "arguments": { "query": "recent news about LLMs", "maxResults": 1 },
-      "name": "rag-web-browser"
-  }
-}'
-
-# The server immediately confirms receipt of the request:
-# Accepted
-```
-
-#### Step 3: Receive the result via SSE
-
-The result is sent back over the SSE connection established in Step 1.
-
-```json
-event: message
-data: {"result":{"content":[{"type":"text","text":"[{\"searchResult\":{\"title\":\"Language models recent news\",\"description\":\"Amazon Launches New Generation of LLM Foundation Model...\"}}]"}]}}
-```
+## Troubleshooting
 
-## Testing and resources
+- _Authorization (API Token):_ If the MCP server isn’t executing Actors, ensure you provided a correct Apify API token. Without a valid `APIFY_TOKEN`, the server cannot start Actor runs. Always set the `APIFY_TOKEN` environment variable when running locally.
+- _Ensure latest version:_ If running via NPM, always use the latest version of `@apify/actors-mcp-server` for the newest features and fixes. You can append `@latest` when installing or in your config args to ensure this.
+- _Node.js environment:_ If running the server locally, make sure Node.js is installed and up to date (`node -v`). The MCP server requires Node.js v18+.
+- _No response or long delay:_ Keep in mind that when an Actor tool is called, it may take some time to complete (depending on the task). If nothing is coming back, check the Actor’s logs in Apify console — the Actor might be waiting on a long operation or input.
 
-- Testing:
-  - Tester MCP Client: Use the [Tester MCP Client](https://apify.com/jiri.spilka/tester-mcp-client) on Apify to interact with either MCP server type. Enter the appropriate server URL (for example, `https://actors-mcp-server.apify.actor/sse` or `https://rag-web-browser.apify.actor/sse`) in the Actor input field, configure your API token, run the client Actor, and interact through its user interface.
