# MCP as the integration layer for public data

_2 August 2026 · 2 min · agents_

AI assistants need live facts, not stale training data. One hosted MCP server fixes that for Estonian public data.

Ask an AI assistant for today's electricity price and it will either guess or tell you it doesn't know. Training data goes stale; public registers don't.

## One server, one step

A hosted MCP server with well-annotated tools lets Claude or Cursor fetch Estonian electricity prices, company filings or parliament votes in a single step. No API keys, no copy-pasting between tabs.

## Operate the endpoint

The value isn't only in the code. It's in running the endpoint reliably, so the assistant can count on it being there when the question comes.
