# lahend.ee MCP server
Free, no-API-key MCP server for **Estonian law**: court decisions, legislation
paragraph by paragraph, and EU law in Estonian - with the citation index that
links them to each other.
```

https://lahend.ee/api/lahend-mcp/sse (SSE)
```
No key, no sign-up, no rate limit worth mentioning. Data comes from Riigi
Teataja, EUR-Lex and HUDOC; company links come from the Estonian Business
Register via [nimistu.ee](https://nimistu.ee).
## What it can do
**Legislation is served in full**, not just case law - each paragraph is
addressable on its own, with every ruling that has ever cited it. That link is
the point of the server: 3.05 million citations extracted from 346,000
decisions, so you can ask what a statute means *in practice* rather than what
it says.
### Case law

### Generic (ChatGPT/Claude connectors)
| Tool | What it does |

| `fetch` | Retrieve the full text + metadata for any `id` returned by `search` |
## Add it
Claude Code:
```bash
claude mcp add --transport http lahend https://lahend.ee/api/lahend-mcp/mcp
```
Any client that takes a remote MCP URL works the same way. `search` and
`fetch` are present so the ChatGPT and Claude connector UIs work out of the
box; the named tools above are better when you know what you want.
## Examples
- *"What does TLS § 88 say, and how have the courts applied it?"* -
`get_law_section` then `rulings_citing_section`.
- *"Which Estonian decisions apply the GDPR?"* -
`estonian_rulings_citing_eu_law` with CELEX `32016R0679`.
- *"Which provisions does this ruling turn on?"* - `sections_cited_by_ruling`.
