Whose server it is
  • Registry namecom.krosos/krososverified in the MCP registry

The registry name sits under krosos.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-24 the server answered initialize and tools/list without a sign-in. First answer in 255 ms.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: Track brokerage, bank and crypto holdings in one view; Estimate capital gains tax by matching sales to purchase lots.
  • Checked on 3 of the 7 days it takes to judge reliability.

Once connected

  • For "Track brokerage, bank and crypto holdings in one view", the likely first call is get_dashboard.
  • For "Estimate capital gains tax by matching sales to purchase lots", the likely first call is get_tax_report.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

Tools it offers12 tools · read 2026-10-24
  • 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.

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "krosos": {
      "type": "http",
      "url": "https://app.krosos.com/api/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http krosos https://app.krosos.com/api/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://app.krosos.com/api/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
