Firmafakta MCP

A remote MCP server over the Swedish company registers (SCB, Bolagsverket, PRV). Your AI assistant counts and lists companies by industry, place and size, and looks up single companies by organisation number.

https://mcp.firmafakta.se

You need a Firmafakta account; the free plan is enough to try it. Sign in with OAuth when your client asks, or send an API key (see below). This repository holds the listing metadata and these instructions; the server itself is not open source.

Install

Claude (claude.ai, Desktop, mobile): add Firmafakta as a connector, then sign in and approve.

Claude Code:

claude mcp add --transport http firmafakta https://mcp.firmafakta.se

Cursor: add to Cursor

VS Code:

code --add-mcp '{"name":"firmafakta","type":"http","url":"https://mcp.firmafakta.se"}'

ChatGPT: under Plugins or Apps, click + and choose Add custom MCP server with the address above. What your plan allows, and whether developer mode must be on, is in OpenAI's help article.

Other clients: add a remote (Streamable HTTP) MCP server with the address above.

Step by step: firmafakta.se/en/ai.

API key

For agents that cannot sign in with OAuth: create a key under My account on firmafakta.se and send it on every request as Authorization: Bearer <key>.
