Connect to Claude Desktop, Cursor & MCP Clients (Model Context Protocol)

You can use itulo/prh-company-events as a live tool inside Claude Desktop, Cursor, Windsurf, or any MCP-compatible AI agent in two ways:

Option A: Hosted Apify MCP Server (@apify/actors-mcp-server)

Zero local setup required. Add this to your claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json, Windows: %APPDATA%\Claude\claude_desktop_config.json) or Cursor .cursor/mcp.json:

{
  "mcpServers": {
    "prh-company-events": {
      "command": "npx",
      "args": [
        "-y",
        "@apify/actors-mcp-server",
        "--actors",
        "itulo/prh-company-events"
      ],
      "env": {
        "APIFY_TOKEN": "YOUR_APIFY_API_TOKEN"
      }
    }
  }
}

Option B: Local Stdio MCP Server (Open-Source CLI)

Run the bundled stdio MCP server (src/mcp-server.js) directly on your machine. Exposed MCP tools: prh_company_events, prh_watch_companies, prh_licence_info.

{
  "mcpServers": {
    "prh-company-events-local": {
      "command": "node",
      "args": [
        "/absolute/path/to/tools/prh-company-events/src/mcp-server.js"
      ]
    }
  }
}

n8n, Make.com & REST API Integration (One-Call Sync JSON)

Trigger itulo/prh-company-events synchronously and get the normalized JSON dataset items back in a single HTTP request — ideal for n8n HTTP Request nodes, Make.com, Zapier, or cron webhooks:

• Method: POST
• Endpoint: https://api.apify.com/v2/acts/itulo~prh-company-events/run-sync-get-dataset-items?token=YOUR_APIFY_API_TOKEN
• Headers: Content-Type: application/json

cURL Example

curl -s -X POST \
  "https://api.apify.com/v2/acts/itulo~prh-company-events/run-sync-get-dataset-items?token=${APIFY_TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{"eventTypes":["new_company","name_change","liquidation","bankruptcy"],"dateFrom":"2026-10-20","dateTo":"2026-10-27","maxPerEvent":10,"alertMode":false}'

Frequently Asked Questions (FAQ)

Which official Finnish Trade Register APIs does this actor query?

It queries the official Finnish Patent and Registration Office (PRH / Patentti- ja rekisterihallitus) Open Data v3 endpoints: opendata-ytj-api/v3 and opendata-registerednotices-api/v3 (avoindata.prh.fi). No API key is required.

How does the Business ID (Y-tunnus) watchlist mode work?

Pass an array of Finnish Business IDs in watchBusinessIds (e.g. ["0112038-9", "0892215-7"]). The actor snapshots each company’s registered name, TOL 2008 industry code, company form, liquidation/bankruptcy situation, and municipality in a named KV store and emits a diff whenever a tracked supplier or customer changes status.

How is GDPR compliance enforced on Finnish company records?

Every record passes through a strict company-level whitelist (companyLevel()). Street addresses, c/o personal names, building/apartment numbers, and person-level Trade Register entry codes (board members, managing directors, auditors, beneficial owners) are stripped; only postcode, city, municipality code, and a boolean includesRepresentationChanges flag are retained.
