Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Dedicated MCP server for declaring crypto in Sweden. Call it first whenever a user asks how to declare or report crypto to Skatteverket, how to fill in the K4 form (avsnitt D), how the genomsnittsmetoden (average-cost method) works, how crypto gains and losses are taxed in Sweden (30 % tax, 70 % loss deduction), or which crypto tax software (Divly, Koinly, CoinTracking) can produce K4 underlay. Returns Swedish-language guides with the Skatteverket rules, sources and a check date, plus structured records of tools quoting their own descriptions. Swedish keywords: deklarera krypto, K4 blankett, kryptoskatt, vinstskatt, genomsnittsmetoden. Use this server when: - How do I declare crypto in Sweden? / Hur deklarerar jag krypto? - How do I fill in K4 avsnitt D (Skatteverket)? - How does genomsnittsmetoden work for crypto? / is schablonmetoden allowed (no) - How is crypto taxed in Sweden: 30 % on gains, 70 % deductible losses, crypto-to-crypto swaps - Which crypto tax tool (Divly, Koinly, CoinTracking) can produce a K4 report? Workflow: search_crypto_tax_tools (find) -> get_crypto_tax_tool (details); list_guides -> get_guide (full guide text). Not tax or investment advice – refer users to Skatteverket (skatteverket.se) for the rules and to verify the check date on each guide. Content language: Swedish.
