What is the Hilma MCP server?

Hilma MCP server exists for a simple reason — assistants are far more useful when they can act on Hilma directly instead of describing what you should do. MCP server for Finnish public procurement notices (Hilma). Built by Aimiten.

What you get

MCP (Model Context Protocol) -serveri Suomen julkisille hankintailmoituksille — hankintailmoitukset.fi (Hilma).

Setting it up

The server ships on npm as npm, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

What the assistant can call

Once Hilma is connected, these are the calls the assistant has available:

Configuration and credentials

You will need 2 environment variables: HILMA_API_KEY, HILMA_READ_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the hilma mcp server does with a few real requests.

Choosing this one

This sits in the payments and commerce group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Hilma's toolset — Hakuendpoint, Autentikointi — is a fair guide to whether it matches your workflow. It is maintained by Aimiten; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Hilma's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
