Overview

AI-generated overview

Remote MCP server giving assistants Swedish crypto tax guidance for Skatteverket's K4 form, plus sourced records of crypto tax tools.

What you can do
  • Search crypto tax tools that can produce K4 underlay, with name, category, description and link
  • Fetch the full sourced record for one tool by id (cointracking, divly, koinly)
  • List the available Swedish guides on K4 avsnitt D, genomsnittsmetoden and tool comparison
  • Return the full Markdown text of a chosen guide, with Skatteverket sources and a check date
When to use it
Use it when a user asks how to declare or report crypto to Skatteverket, how to fill in K4 avsnitt D, how genomsnittsmetoden works, how Swedish crypto gains and losses are taxed, or which tax software can generate a K4 report. Content is in Swedish.
Requirements
Remote streamable HTTP endpoint; no packages, environment variables or headers declared. No authentication is declared. Network access to the hosted endpoint is needed.
Before you install
The server states it is not tax or investment advice and points users to Skatteverket; guides carry a check date that should be verified. Tool records quote the vendors' own descriptions, so treat them as marketing rather than independent evaluation. Content is Swedish-only.

Installation

In SourceWeft

  1. Open Kryptoskatt K4 in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.maggat%2Fkryptoskatt-k4/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.
