Ask about any\nEstonian company, person, trademark, or activity sector in plain\nlanguage — **free, no API key, read-only** — with every answer traceable to its source.\n\nPowered by **[nimistu.ee](https://nimistu.ee)**, a free, ad-free public register that\naggregates 60+ official Estonian open-data sources, each field carrying its source and\nlast-update date.\n\n- **Endpoint (Streamable HTTP):** `https://nimistu.ee/api/mcp`\n- **Free** — no API key, no signup, read-only\n- **Bilingual** — Estonian and English\n- **Traceable** — every answer is source- and date-stamped\n\n## Quick start\n\n### Claude Code\n\n```bash\nclaude mcp add --transport http nimistu https://nimistu.ee/api/mcp\n```\n\n### Cursor\n\nAdd to `~/.cursor/mcp.json` (global) or `.cursor/mcp.json` (project):\n\n```json\n{\n  \"mcpServers\": {\n    \"nimistu\": {\n      \"url\": \"https://nimistu.ee/api/mcp\"\n    }\n  }\n}\n```\n\n### Claude Desktop and other clients\n\n```json\n{\n  \"mcpServers\": {\n    \"nimistu\": {\n      \"url\": \"https://nimistu.ee/api/mcp\"\n    }\n  }\n}\n```\n\nStdio-only clients can bridge via [`mcp-remote`](https://www.npmjs.com/package/mcp-remote):\n\n```json\n{\n  \"mcpServers\": {\n    \"nimistu\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"mcp-remote\", \"https://nimistu.ee/api/mcp\"]\n    }\n  }\n}\n```\n\n**Transports:** Streamable HTTP at `https://nimistu.ee/api/mcp` (recommended) · SSE at\n`https://nimistu.ee/api/sse`.\n\n## What you can ask\n\nYou talk to it in natural language — you don't need to know table names or tool details.\n\n- Tell me about an Estonian OÜ — owners, board, financials\n- Which companies is a given person connected to?\n- What happened in the Estonian Business Register today?\n- Top 10 taxpayers and employers in Estonia\n- Find trademarks containing a word — and who owns them\n- How many retail companies (EMTAK 47.8) are there, and where?\n- Compare the 2024 financials of three companies\n\n## Capabilities\n\nTen tools over the full nimistu.ee dataset:\n\n| Capability | What it covers |\n| --- | --- |\n| **Company profile** | status, address, activity (EMTAK), VAT, employees, financials, tax debt, board (with appointment dates), owners, trademarks |\n| **Annual reports** | every filed majandusaasta aruanne: revenue, profit, employees, equity, assets, liabilities, labour cost, plus computed ratios and the EMTAK sector median |\n| **Ownership structure** | subsidiaries, associates, foreign parent, group structure |\n| **Person & connections** | a person's current and former ties to Estonian companies (board, shareholder, representative) |\n| **Fresh registry events** | what changed in the Estonian Business Register today |\n| **Rankings** | curated top lists — taxpayers, employers, procurement winners, MPs in business, and more |\n| **Trademark search** | EUIPO trademarks by text, with their owners |\n| **Sector lookup** | companies by EMTAK activity code, with counts and locations |\n| **EMTAK classification** | resolve and explain Estonian activity codes |\n\n## What it does not cover\n\nWorth knowing before you rely on a negative answer:\n\n- **Registry entry history.** Company profiles are current state only — no kanded,\n  no määrused, no pending menetlused. An answer about a company is about today,\n  and will not mention an ongoing proceeding.\n- **Beneficial owners.** Estonia's FIU withdrew public access to the beneficial\n  owner register on 10 July 2026 following the CJEU ruling, so this server no\n  longer returns them.\n- **Court decisions and public-authority documents.** Separate corpora, served by\n  [lahend.ee](https://lahend.ee/mcp) and\n  [dokumendiregister.ee](https://dokumendiregister.ee/mcp) respectively.\n- **Real-time data.** Sources refresh on their own cadences, mostly nightly.\n  `get_company` returns `dataAsOf` so you can see how stale an answer is rather\n  than having to assume.\n\n## Data sources and attribution\n\nnimistu aggregates 60+ official sources — Äriregister (RIK), the Estonian Tax and\nCustoms Board (EMTA), EUIPO, public-procurement registers, sanctions lists, and more.\nEach field shows its source and last-update date.\n\n- Sources: <https://nimistu.ee/allikad>\n- Usage terms: <https://nimistu.ee/litsents>\n- Machine-readable index for agents: <https://nimistu.ee/llms.txt>\n\n## Links\n\n- Website — <https://nimistu.ee>\n- MCP connection page — <https://nimistu.ee/mcp>\n\n## License\n\nThe configuration examples and documentation in this repository are released under the\n[MIT License](LICENSE).
