Estonia Business Register

What Estonia Business Register does

Estonia Business Register exposes selected data from RIK, the Estonian Centre of Registers and Information Systems, through MCP. Its records cover registered, liquidating, and bankrupt entities, including company identity, legal form, VAT number, registration status, address, and currently reported EMTAK/NACE activity areas.

The service also provides selected information from filed annual reports. Available data includes report submission metadata, audited status, filer-size category, revenue, profit or loss, total assets, equity, average full-time-equivalent employees, and sales revenue grouped by activity area. Annual-report extracts cover reports filed from 2019 through 2025.

Beneficial-owner information is handled differently: the relevant tool reads the public company page from RIK at request time rather than using the bulk mirror. It can return owner names, dates of birth, nationality, control type, and the start date of the holding.

How it works

Connect an MCP client to the Pipeworx endpoint at https://gateway.pipeworx.io/estonia-business-register/mcp. The gateway holds the daily-refreshed copy of RIK's bulk data and serves the register tools without requiring an API key. A standalone package installation cannot answer queries because the data is available through the gateway runtime.

Each response includes data_as_of and source; licence information is included where applicable. For ordinary register data, data_as_of identifies the mirror refresh date. For beneficial owners, it reflects the last update date shown for that section on RIK's page.

The endpoint also exposes shared Pipeworx meta-tools, so its complete tool list is larger than the four register-specific tools. A full Pipeworx gateway URL is also available at https://gateway.pipeworx.io/mcp.

Setup and configuration

Add the pack endpoint to an MCP client configuration:

{
  "mcpServers": {
    "estonia-business-register": {
      "url": "https://gateway.pipeworx.io/estonia-business-register/mcp"
    }
  }
}

The connection is keyless. No environment variables or credentials are required. Claude Desktop, Cursor, and Windsurf are named as supported connection targets.

Tools and capabilities

• ee_company retrieves one entity by registry code or exact current registered name. It returns identity, legal form, VAT number, status, address, and current activities.
• ee_company_search searches current names by prefix, with diacritics ignored. It supports status filters for registered, liquidation, and bankrupt entities, and can fall back to a weaker substring match.
• ee_annual_report_stats lists filed-report years and metadata, or returns selected indicators and sales-by-activity figures for a chosen year.
• ee_beneficial_owners reads beneficial-owner details live from RIK using a registry code or name.

Name matching uses current names only. A former company name will not resolve through the name parameter, so a registry code is needed after a rename. Status values are represented as R for registered, L for liquidation, and N for bankrupt, with English and Estonian labels available.

Limitations and notes

The service does not provide full annual reports. Some filed reports contain metadata but no matching standardized financial figures; those results contain null values rather than being omitted. Activity data represents currently reported areas, not historical or ended activities.

RIK's page does not provide an address for beneficial owners, and this service does not collect one.
