## MCP tools (4)

### `ee_company` (~232 tokens)

One Estonian company or other registered entity by its registry code or exact current name, from Estonia's e-Business Register (published as open data by RIK, the Estonian Centre of Registers and Information Systems). Returns identity (name, legal form, VAT number), registration status (registered/in liquidation/bankrupt), address, and currently reported EMTAK/NACE activity areas. Use for "what is the status of registry code 12417834" or "look up Bolt Technology OÜ". A company's CURRENT registered name is matched exactly -- a FORMER name (e.g. a company later renamed) will not match by name; look it up by registry code instead if known. For partial name matches use ee_company_search first.

Input parameters:

- `name` (string): Exact current registered name, e.g. "Bolt Technology OÜ". Case/diacritic-insensitive (works with or without õ/ä/ö/ü). Use ee_company_search for partial names.
- `registry_code` (string): Estonian registry code (ariregistri kood), e.g. "12417834".

### `ee_company_search` (~271 tokens)

Search Estonia's e-Business Register (RIK open data) by the start of a company's current name, optionally filtered by registration status (registered, liquidation or bankrupt; any other value is refused, not ignored). Prefix match first ("Bolt" finds "Bolt Technology OÜ" but not "EuroBolt OÜ"); only when nothing starts with the text does it fall back to a weaker contains-the-text pass and report match_mode:'substring'; diacritic-insensitive, so plain-ASCII and Estonian spellings both work; the legal form is optional and can sit either side ("Tallinna Sadam", "Tallinna Sadam AS" and "AS Tallinna Sadam" all find "aktsiaselts TALLINNA SADAM"), and the company whose name matches exactly apart from its legal form is listed first. Use for "find Estonian companies named Bolt..." or to get a registry code to pass to ee_company.

Input parameters:

- `limit` (number): Maximum results (1-100, default 20).
- `name` (string, required): Start of the company's current registered name, e.g. "Bolt".
- `status` (string): Filter by registration status. "active" is a synonym for "registered". Case-insensitive; any other value is refused with the valid list.

### `ee_annual_report_stats` (~200 tokens)

Selected financial indicators and sales-by-activity breakdowns from an Estonian entity's filed annual reports (RIK's monthly open-data extracts of e-Business Register annual reports) -- NOT full reports. Pass registry_code alone to list every year with a filed report (submission date, audited flag, filer-size category); add year for that year's figures: revenue, profit/loss, total assets, equity, average full-time-equivalent employee count, and sales revenue broken down by EMTAK activity area. Some filed reports carry metadata but no matching figures in RIK's extract (seen for some large/group filers) -- the report row still answers, with null figures.

Input parameters:

- `registry_code` (string, required): Estonian registry code (ariregistri kood), e.g. "11056239".
- `year` (string): Report year, e.g. "2024". Omit to list every year with a filed report.

### `ee_beneficial_owners` (~239 tokens)

An Estonian entity's beneficial owners (Estonia's e-Business Register, published by RIK, the Estonian Centre of Registers and Information Systems) by registry code or exact current name: each owner's name, date of birth and nationality EXACTLY as the register itself shows them, the manner in which control is exercised (direct/indirect ownership etc.), and the start date of that holding. RIK marks this data as informative rather than authoritative, and the register carries no live per-record API for it -- this tool reads the register's own public company page, live, per request, so data_as_of reflects RIK's own last-updated date for the beneficial-owners section specifically. Anyone named here can request removal at support@pipeworx.io; a removal already on file is silently withheld and counted in withheld_by_removal_request.

Input parameters:

- `name` (string): Exact current registered name. Use ee_company_search first for a partial match, or pass registry_code directly if known.
- `registry_code` (string): Estonian registry code (ariregistri kood), e.g. "11056239".

## Common questions

### What is the Estonia Business Register MCP server?

Estonia Business Register is an MCP server listed in the public MCP registry as io.github.pipeworx-io/estonia-business-register. estonia-business-register -- Estonia's e-Business Register, published as open data by RIK… This page covers its npm package (@pipeworx/mcp-estonia-business-register).

### Is the Estonia Business Register MCP server safe to use?

Estonia Business Register scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Estonia Business Register MCP server expose?

Estonia Business Register exposes 4 tools: ee_company, ee_company_search, ee_annual_report_stats, ee_beneficial_owners. Their descriptions and schemas cost roughly 942 tokens of context every time the server is loaded.

### Is the Estonia Business Register MCP server still maintained?

Estonia Business Register is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Estonia Business Register MCP server under?

Estonia Business Register declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Estonia Business Register MCP server?

VerifyMCP ran 15 checks on Estonia Business Register, covering Malware scan, Known CVEs, Install scripts, Dependency health and 11 more. One item could not be completed, a gap on our side rather than a finding about Estonia Business Register: Security disclosure. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
