🇨🇭 Part of the Swiss Public Data MCP Portfolio

🏦 swiss-snb-mcp

MCP server for the Swiss National Bank (SNB) data portal — exchange rates, balance sheet, interest rates, SARON, monetary aggregates, banking statistics, and balance of payments.

🇩🇪 Deutsche Version

Overview

swiss-snb-mcp connects AI models to the official Swiss National Bank data portal at data.snb.ch via the Model Context Protocol (MCP). It provides structured access to SNB's public REST API — no authentication required.

The server covers three tiers of datasets, all confirmed against the live API:

Phase 1 — Dedicated tools:

• Exchange rates (monthly averages, month-end rates, annual averages) for the 28 currency series devkum publishes against CHF — including two USD forward rates, which are labelled as such
• SNB balance sheet (Bilanz): gold reserves, foreign exchange investments, banknotes in circulation, sight deposits, and totals

Phase 2 — Via generic cube tools (snb_get_cube_data + snb_get_cube_metadata):

• SNB policy rate (Leitzins) and SARON daily fixing, emergency facility rate, sight deposit rates
• SARON compound rates: Overnight, 1M, 3M, 6M
• International money market rates: SARON (CH), SOFR (USA), TONA (JP), SONIA (UK), €STR/EURIBOR (EZ)
• Official central bank rates: SNB, Fed, ECB, Bank of England, Bank of Japan
• Monetary aggregates M1, M2, M3: stock levels and year-on-year changes

Phase 3 — Warehouse API (banking statistics) and balance of payments:

• Banking balance sheets (BSTA BIL): total assets and liabilities by bank group — annual and monthly
• Banking income statements (BSTA EFR): operating income, expenses, taxes by bank group — annual
• Balance of payments: current account, capital account, financial account (quarterly)
• International investment position: components by investment type (quarterly)
• Generic warehouse access: raw access to any SNB Warehouse cube by ID

Anchor demo query: "What was the EUR/CHF exchange rate during the 2015 Franc shock, and where does the SNB policy rate stand today compared to the Fed and ECB?"

Features

• 💱 Exchange rates — monthly CHF rates for EUR, USD, JPY, GBP, CNY and 23 more series
• 📅 Annual averages — year-by-year rates from 1980 onwards
• 🏛️ SNB balance sheet — gold, foreign exchange investments, banknotes, sight deposits (monthly)
• 🔄 Currency conversion — convert any amount to CHF using official SNB rates
• 📈 Policy rate & SARON — daily fixing, Leitzins, compound rates (1M/3M/6M)
• 🌍 International rate comparison — SNB, Fed, ECB, Bank of England, Bank of Japan side by side
• 💰 Monetary aggregates — M1, M2, M3 stock levels and year-on-year growth
• 🏦 Banking statistics — balance sheets and income statements by bank group (12 groups)
• 📊 Balance of payments — current account, IIP, and international investment position
• 🔍 Generic cube access — query any SNB data cube or Warehouse cube by ID
• 🔓 No authentication required — fully public SNB data portal
