Ask Claude and ChatGPT about any Belgian company
The Addrly MCP connector gives your AI assistant the official Belgian registers. Paste one address, log in with your Addrly account, click Allow, then ask in plain language: the assistant finds the company, builds the list or opens the dossier itself.

Read only, Belgium only
The assistant reads and changes nothing in your account. It covers Belgian companies and addresses, nothing else.

Read the documentationFrequently asked questions
Is the connector free?
The connector is included in every plan, the free plan too. What the assistant looks up is counted like an API call: a page of search results is 1 request, a dossier is 1 dossier, charged once per company per billing period. Reading your plan, the filter values and the activity codes is free.
Which assistants can I use?
Claude (claude.ai, Claude Desktop, Claude Code) and ChatGPT in developer mode, or any assistant that connects to a remote MCP server with OAuth. Addrly is not listed in their connector directories yet: you add it with its address.
What can the assistant change?
Nothing. Every tool reads: companies, dossiers, addresses, your plan. It cannot edit your portfolios, your plan or your account.
What does the assistant receive?
The answers to the questions you ask it, and nothing else of your account: no password, no API key. Those answers then go to the provider of your assistant, which you chose: Anthropic and OpenAI are not Addrly subprocessors.
How do I disconnect it?
From the Keys & usage page of the app, where every connected assistant is listed with the member who allowed it. An administrator can disconnect a colleague's, and a member who leaves the organisation loses their connections.
Does it cover other countries?
No. Addrly covers Belgium only: the BCE/KBO register, the annual accounts filed with the National Bank, the Belgian Official Gazette and the BOSA addresses.
Try it on your own customers
The free plan gives you 20 complete company dossiers every month, no card required. Move to a paid plan when you need more, and cancel whenever you like.
