Connect Tweede Kamer

The Tweede Kamer publishes its own archive: every motion, every decision, every vote per faction, and the verbatim record of every debate. This connector makes that answerable. ORI and OpenBesluitvorming cover municipalities, provinces and water authorities; this one covers the national parliament.

What this connector can and cannot do

Search looks at the TITLE of a paper only. This platform has no full-text search, and on a measured sample title search missed 59 to 100 percent of the papers that mention a term in their body. Treat a hit as a candidate, then read the paper.
Searching the CONTENT of papers is possible, but it does not come from the Tweede Kamer: it is provided by opentk.nl, an independent open-source service by bert hubert that downloads the Kamer's papers, extracts their text (scans through OCR) and indexes it. Every answer from the tool names that origin; the papers themselves remain the Kamer's.
The text of a paper exists for about a quarter of them: roughly half since 2021, almost none before 2018. Where it is absent the connector returns nothing rather than an unreliable PDF extraction.
Votes per faction, with seat counts that total 150. Votes cast by mistake are recorded as such, which is how a motion can pass against the intent of the chamber.
Verbatim records of the sittings, with each speaker’s name, faction and the platform’s own person identifier, so a quote can be attributed.
The cabinet’s position on a motion (Ontraden, Oordeel Kamer). No other Dutch source publishes that as data.

ChatGPT Connecting with ChatGPT

ChatGPT can use BesluitBron too. The route differs from Claude's: with Claude you add an ordinary custom connector, with ChatGPT it sits behind a developer setting.

Needed: ChatGPT in a web browser and a paid plan on which developer mode is available. In a Business or Enterprise workspace an administrator has to allow it first, under Workspace Settings → Permissions & Roles → Connected Data. OpenAI states this mode is meant for developers.

In ChatGPT, open your profile picture at the top right and go to Settings.
Go to Connectors (called Apps in some versions) and open Advanced settings at the bottom.
Switch on Developer mode.
Under Connectors, add a remote MCP server and paste the URL below. For authentication, choose none.
