Connects to your Krosos accounting ledger to show net worth, balance sheet, transaction history, capital gains tax estimates, and investment projections. Log trades and balance adjustments, sync connected exchanges and bank accounts, and pull current market prices.

Example request: "What's my current net worth and how much in capital gains tax do I owe this year?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Krosos to help me. It is a free service with an MCP server at https://app.krosos.com/api/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- get_dashboard: Net worth, balance sheet and current holdings, in the ledger's base currency.
- get_net_worth_history: Historical net-worth snapshots (one point per day where recorded).
- list_transactions: Transaction history as a human-friendly list, newest first.
- get_reference_data: Valid accounts, providers, tickers, asset classes and categories. Read this before writing: trades and adjustments must use these values unless allow_new_values is set.
- get_tax_report: Capital-gains / income tax estimate for a year: gains, losses, exemption (including any carried-forward amount), taxable base and estimated tax.
- get_projection_config: The forecast/FIRE plan's assumptions (salary, expenses, inflation, retirement dates, tax mode). The projection itself is computed client-side.
- get_prices: Current price per ticker with its source, quote currency and recent change, plus any manual overrides.
- refresh_prices: Fetch fresh market prices now. With no ticker this refreshes every priced holding; with one it refreshes just that ticker.
- list_connections: Linked exchange, bank and wallet connections, each with its sync mode (balance updates, or transactions staged for review) and when it last synced.
- sync_connections: Sync every linked connection in one pass: push the latest balance into each linked holding, and stage new transactions into the review queue. Reports what was written, what was staged and any per-provider errors.
- log_trade: Log a trade (buy / sell / swap), expressed as from-asset to to-asset. Same body and validation as POST /api/transactions.
- record_balance_adjustment: Record a signed quantity change on one holding (a balance update that is not a trade). Same body and validation as POST /api/position-adjustments.
