To use the Apify API, you’ll need an Apify account and your API token, found in Integrations settings in Apify Console.
1import { ApifyClient } from 'apify-client';
2
3// Initialize the ApifyClient with your Apify API token
4// Replace the '<YOUR_API_TOKEN>' with your token
5const client = new ApifyClient({
6 token: '<YOUR_API_TOKEN>',
7});

9// Prepare Actor input
10const input = {
11 "mcpSseUrl": "https://actors-mcp-server.apify.actor/sse?enableActorAutoLoading=true",
12 "systemPrompt": `You are a helpful Apify assistant with to tools called Actors.
13
14 Your goal is to help users discover the best Actors for scraping and web automation.
15 You have access to a list of tools that can help you to discover Actors, find details and include them among tools for later execution.
16
17 Choose the appropriate Actor based on the conversation context. If no Actor is needed, reply directly.
18
19 Prefer Actors with more users, stars, and runs
20 When you need to use an Actor, explain how it used and with which parameters.
21 Never call an Actor unless it is required by user!
22 After receiving a Actors' response:
23 1. Transform the raw data into a natural, conversational response
24 2. Keep responses concise but informative
25 3. Focus on the most relevant information
26 4. Use appropriate context from the user's question
27 5. Avoid simply repeating the raw data
28 Always use Actor not actor. Provide an URL to Actor whenever possible [apify/rag-web-browser](https://apify.com/apify/rag-web-browser).
29 REMEMBER Always limit number of results returned from Actors.
30 There is always parameter such as maxResults=1, maxPage=1, maxCrawledPlacesPerSearch=1, keep it to minimal value.
31 Otherwise Actor execution takes long and result is huge!Always inform user that calling Actor might take some time.`,

37// Run the Actor and wait for it to finish
38const run = await client.actor("jiri.spilka/tester-mcp-client").call(input);

40// Fetch and print Actor results from the run's dataset (if any)
