DigitalK2 MCP server

DigitalK2 plugin

Swedish annual reports (årsredovisning) for small limited companies under K2, prepared with your AI in Claude, ChatGPT, Cursor or Codex.

DigitalK2 is a hosted service for annual reports (årsredovisning) for small Swedish limited companies (aktiebolag) under the K2 rules. It produces the annual report in iXBRL, the tax calculation and the INK2 tax return, and files the report digitally with Bolagsverket. This repository connects AI agents to the DigitalK2 MCP server, so your AI can upload the SIE file, review the figures, read the tax calculation and fill in the report together with you.

It contains an MCP server configuration, plugin manifests for Claude Code, Cursor, Codex and the plugins CLI, and a skill that tells the agent how to use the tools.

MCP server URL:

https://mcp.digitalk2.se/mcp

Sign-in happens with OAuth in your browser the first time the agent connects, with your DigitalK2 account. No API key is needed. You choose the permissions: Read (see drafts, figures, tax calculation) and Prepare (fill in and change drafts in steps 1 to 6).

How it works

The AI works in the same guided flow as the web guide, with the same checks. You keep the draft open on digitalk2.se in AI mode next to the chat and see everything the AI fills in. Payment, personal identity numbers, signing and filing with Bolagsverket are always done by you on the web in step 7, never by the AI.
