The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
search_etfs open 24h ago
Search and filter the European UCITS ETF universe. Args: query: Search term matched against ETF Name, ISIN, or Ticker. domicile: Filter by domicile country (e.g., 'Ireland', 'Luxembourg'). accumulating_only: If True, only returns accumulating ETFs (tax-efficient). max_ter: Maximum Total Expense Ratio (TER), e.g. 0.002 (0.20%). min_aum: Minimum fund size (Assets Under Management) in EUR millions. limit: Limit the number of search results returned (defaults to 15).

Trigger a scrape of JustETF to fetch fresh ETF data and update the local cache. This runs in the background and may take a few minutes to complete.
{ "type": "object", "title": "refresh_etf_dataArguments", "properties": {} }arguments 5 linesget_etf_details unknown 24h ago
Retrieve comprehensive details for a specific ETF by its ISIN. Args: isin: The International Securities Identification Number (ISIN) of the ETF.
{ "type": "object", "title": "get_etf_detailsArguments", "required": [ "isin" ], "properties": { "isin": { "type": "string", "title": "Isin" } } }arguments 13 linescalculate_tax_efficiency unknown never probed

{ "type": "object", "title": "calculate_tax_efficiencyArguments", "required": [ "isin" ], "properties": { "isin": { "type": "string", "title": "Isin" } } }arguments 13 linesgenerate_612_chart unknown never probed
Generate 6-week and 12-month ETF performance data with year-over-year comparison. Returns structured JSON with weekly/monthly returns, cumulative growth curves, and summary metrics including inflation-adjusted purchasing power.

Calculate the annual Vorabpauschale (advance lump-sum tax) for a German-taxable ETF position. The Vorabpauschale is a deemed annual income on accumulating fund shares, taxed in January of the following year regardless of whether the fund distributed anything. It depends on the ECB Basiszins rate published by the Bundesbank. This is a tax calculation tool — not financial advice. Args: isin: ETF ISIN (e.g., "IE00BK5BQT80" for Vanguard FTSE All-World Acc). position_value_jan1: Market value of the position on January 1 of tax_year (EUR). purchase_price: Original total acquisition cost of the position (EUR). tax_year: Calendar year to calculate for (determines Basiszins).

Simulate German exit tax (Wegzugsbesteuerung §6 AStG) on ETF holdings for emigration planning. Since Jan 1 2025, ETF holdings above €500k total acquisition cost trigger exit tax when leaving Germany (if resident ≥7 of last 12 years). This tool simulates the liability and shows deferral/mitigation options. This is a tax simulation tool — not financial or legal advice. Args: positions: List of ETF positions, each a dict with keys: "isin", "purchase_price", "current_value" (all in EUR). years_resident: Years of German tax residency in the last 12 years. Default: 10. destination_country: "EU", "EEA", or "non-EU" — affects deferral options. include_deferral_options: Whether to include mitigation/deferral guidance. Default: True.
{ "type": "object", "title": "calculate_exit_tax_toolArguments", "required": [ "positions" ], "properties": { "positions": { "type": "array", "items": {}, "title": "Positions" }, "years_resident": { "type": "integer", "title": "Years Resident", "default": 10 }, "destination_country": { "type": "string", "title": "Destination Country", "default": "non-EU" }, "include_deferral_options": { "type": "boolean", "title": "Include Deferral Options", "default": true } } }arguments 29 linescalculate_sell_tax_tool unknown never probed
Calculate the exact capital gains tax when selling an ETF position in Germany. Accounts for Teilfreistellung (partial exemption), Vorabpauschale credits (no double tax), and Sparerpauschbetrag (€1,000 annual allowance). Useful for evaluating the tax cost of rebalancing before you sell. This is a tax calculation tool — not financial advice. Args: isin: ETF ISIN to sell. purchase_price: Original total acquisition cost of the position (EUR). current_value: Current market value / expected sale proceeds (EUR). previously_paid_vorabpauschale: Total Vorabpauschale already taxed on this position (EUR). Credited against gains. sparerpauschbetrag_remaining: Remaining annual tax-free allowance (EUR). Default: €1,000. kirchensteuer: Whether church tax applies. Default: False. bundesland: German state for Kirchensteuer rate (e.g., "Bayern" for 8%, default: 9%).

Look up the Teilfreistellung (partial tax exemption) classification for an ETF. Returns the tax-exempt portion rate under §20 InvStG: - Aktienfonds (≥51% equity): 30% of gains are tax-exempt - Mischfonds (≥25% equity): 15% of gains are tax-exempt - Sonstige (<25% equity, e.g. bonds): 0% exempt This directly impacts after-tax returns and is not surfaced by most ETF screeners. Args: isin: ETF ISIN to classify (e.g., "IE00BK5BQT80").
{ "type": "object", "title": "get_teilfreistellung_toolArguments", "required": [ "isin" ], "properties": { "isin": { "type": "string", "title": "Isin" } } }arguments 13 linescompare_after_tax_tool unknown never probed

Essential for understanding whether your "diversified" portfolio is actually diversified. Args: isins: List of 2-10 ETF ISINs in your portfolio (e.g., ["IE00BK5BQT80", "IE00B5BMR087"]). weights: Optional portfolio weights matching the ISINs (must sum to 1.0). Equal weight if omitted.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idfb71739cb4e23101.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
