Firmafakta — Claude Code MCP server: Swedish company data
A remote MCP server that lets your assistant count and list Swedish companies by industry, place and size, and pull everything on a single firm.
claude mcp add --transport http firmafakta https://mcp.firmafakta.seWhat Firmafakta does
The server sits on top of Swedish registers — SCB, Bolagsverket, PRV. Ask for a segment and the assistant returns a count or a paged list; hand it an organisation number and it returns the full record for that company. Segments are built from industry, place and size.
Seven tools ship with it. firmafakta_describe explains the segment language, the fields and what each plan costs, firmafakta_find_codes resolves SNI codes, municipalities and counties from free text, firmafakta_count returns a number and reads it back in words, firmafakta_fetch pages through companies or workplaces, firmafakta_lookup gathers one company's details. The remaining two, firmafakta_save and firmafakta_load, handle saved segments.
A Firmafakta account is required, and the free plan covers a trial. Sign in with OAuth when your client prompts for it, or create an API key under My account on firmafakta.se and send it on each request as Authorization: Bearer <key>. Counting and fetching draw on credits, the same ones used on the website. Sole proprietorships get counted but never listed, so a “show me all of them” request will not match the number you were given.
What it helps with
- count construction firms in Halland by employee band
- export a list of accounting firms for one municipality
- narrow a segment to companies registered recently
- resolve SNI codes and municipality names from text
- pull the full record for one organisation number
Example prompts for the agent
- List the accounting firms in Gothenburg municipality.
- Same segment, but keep only firms registered in the last five years.
