Swedish company data, in Claude Code.

One MCP server, nine tools, every Swedish company — listed and unlisted. Drop it into Claude Code with one command and ask in plain English.

claude mcp add regna -e REGNA_API_KEY=rk_... -- \
  uvx --from git+https://github.com/regna-tech/regna-mcp-server regna-mcp

Step 1 — Install

MCP install, 30 seconds.

Pick your client. Each command is one line; the server is the same Python package either way.

Claude Code (CLI)

claude mcp add regna \
  -e REGNA_API_KEY=rk_... -- \
  uvx --from \
    git+https://github.com/regna-tech/regna-mcp-server \
    regna-mcp

      ],

{
  "mcpServers": {
    "regna": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/regna-tech/regna-mcp-server",
        "regna-mcp"
      ],
      "env": { "REGNA_API_KEY": "rk_..." }
    }
  }
}

Continue — .continue/config.yaml

mcpServers:
  - name: regna
    command: uvx
    args:
      - --from
      - git+https://github.com/regna-tech/regna-mcp-server
      - regna-mcp
    env:
      REGNA_API_KEY: rk_...

The git+https prefix is temporary — once the package lands on PyPI you'll be able to swap it for plain uvx regna-mcp-server. Both run the same code.

Step 2 — What you get

Nine tools, one API key.

Each tool maps to a Regna REST endpoint — same data shapes, same provenance, same SLA. Claude picks which to call.

lookup_company

Registry profile by 10-digit org number.

search_companies

Name or partial-name search across the registry.

validate_org_number

Luhn check and existence verification.

get_financials

Annual or quarterly financial data.

get_analysis

Health score, valuation, and risk assessment.

get_similar_companies

Peers by industry and geography.

get_company_events

Recent news, filings, and registry changes.

get_reports

Source filings (annual reports) for any company.

batch_lookup

Up to 100 companies in one call.

Try asking

> prompt

Look up org 5567037485 and tell me what they do.

> prompt

Compare Spotify AB and Klarna AB on revenue and operating margin.

> prompt

Build me a one-page research note on Northvolt — financials, peers, recent events.

Step 3 — Skills (optional)

Pre-baked workflows for lookup, screen, compare, and research.

The skills package teaches Claude when to chain which tools so common tasks Just Work. Bilingual: English and Swedish prompts both trigger.

npx -y github:regna-tech/regna-claude-skills install

regna-lookup

Single-company registry profile.

regna-screen

Filter the universe by industry, revenue, or geography.

regna-compare

Side-by-side on financials and health.

regna-research

One-page deep-dive on a single company.

Use it from claude.ai (Cowork)

Same server, remote.

Claude Cowork in claude.ai connects to remote MCP servers over Streamable HTTP. Add Regna as a custom connector with your API key as the Bearer token.

Connector config

URL:    https://mcp.regnaverkt.com/mcp
Header: Authorization: Bearer rk_...

The hosted server is the same Python code as the local install — FastMCP runs both transports from one binary. Each request carries its own Bearer key, so quota and rate limits apply per-tenant just like the REST API.
