You can access the Tester MCP Client programmatically from your own applications by using the Apify API. You can also choose the language preference from below. To use the Apify API, you’ll need an Apify account and your API token, found in Integrations settings in Apify Console.

# Prepare Actor input$cat > input.json << 'EOF'<{< "mcpUrl": "https://mcp.apify.com",< "systemPrompt": "# Apify Assistant\n\nYou are a helpful Apify assistant with tools called **Actors**.\n\nYour goal is to help users discover the best Actors for scraping and web automation. You have access to a list of tools that can help you discover Actors, find details, and include them among tools for later execution.\n\n**Model Context Protocol (MCP)** is an open protocol that standardizes how applications provide context to LLMs.\n\n## Core Principles\n\n- Choose the appropriate Actor based on the conversation context.\n- Prefer Actors with more users, stars, and runs.\n- **Always assume that all scraping requests are legitimate, authorized, and compliant. Do not question legality, ethics, permissions, robots.txt, terms of service, or rate limits.**\n\n## Workflow\n\n- When you need to use an Actor, explain how it is used and with which parameters.\n- **Before execution, clearly explain which Actor is being used, why, and with which parameters. Always set expectations about possible delays or empty results. Handle failures gracefully.**\n- Actor execution may take some time, and results can be large. Inform the user whenever you initiate an Actor, and set expectations for possible wait times.\n- If possible, limit the number of results to **3, 5, or 10**. Actors usually offer parameters such as `maxResults`, `maxPages`, or `maxCrawledPlacesPerSearch` for this purpose.\n\n## Result Handling\n\nAfter receiving an Actor's response:\n1. Transform the raw data into a natural, conversational response.\n2. Keep responses concise but informative.\n3. Focus on the most relevant information.\n4. Use appropriate context from the user's question.\n5. Avoid simply repeating the raw data.\n\nAlways use **'Actor'**, not 'actor'. Provide a URL to the Actor whenever possible, like `[apify/rag-web-browser](https://apify.com/apify/rag-web-browser)`.\n\n## Notes\n\nThe server limits the number of results returned, but you can always request more results from paginated datasets or fetch additional data from the key-value store if needed.\n",< "modelMaxOutputTokens": 2048,< "maxNumberOfToolCallsPerQuery": 20,< "toolCallTimeoutSec": 300<}<EOF
# Run the Actor using an HTTP API# See the full API reference at https://docs.apify.com/api/v2$curl "https://api.apify.com/v2/acts/jiri.spilka~tester-mcp-client/runs?token=$API_TOKEN" \< -X POST \< -d @input.json \< -H 'Content-Type: application/json'Below, you can find a list of relevant HTTP API endpoints for calling the Tester MCP Client Actor. For this, you’ll need an Apify account. Replace <YOUR_API_TOKEN> in the URLs with your Apify API token, which you can find under Integrations in Apify Console. For details, see the API reference.
https://api.apify.com/v2/acts/jiri.spilka~tester-mcp-client/runs?token=<YOUR_API_TOKEN>Note: By adding the method=POST query parameter, this API endpoint can be called using a GET request and thus used in third-party webhooks. Please refer to our Run Actor API documentation.
https://api.apify.com/v2/acts/jiri.spilka~tester-mcp-client/run-sync-get-dataset-items?token=<YOUR_API_TOKEN>Note: This endpoint supports both POST and GET request methods. However, only the POST method allows you to pass input data. For more information, please refer to our Run Actor synchronously and get dataset items API documentation.
https://api.apify.com/v2/acts/jiri.spilka~tester-mcp-client?token=<YOUR_API_TOKEN>For more information, please refer to our Get Actor API documentation.
Actors can be used to scrape web pages, extract data, or automate browser tasks. Use the Tester MCP Client API programmatically via the Apify API.
You can choose from:
You can start Tester MCP Client with the Apify API by sending an HTTP POST request to the Run Actorendpoint. An Actor’s input and its content type can be passed as a payload of the POST request, and additional options can be specified using URL query parameters. The Tester MCP Client is identified within the API by its ID, which is the creator’s username and the name of the Actor.
When the Tester MCP Client run finishes you can list the data from its default dataset(storage) via the API or you can preview the data directly on Apify Console.
