Installation

1. Install dependencies

pip install mcp swiss-finance-data

Or from the repo root (installs the local package):

pip install mcp
pip install -e ..

2. Claude Code

Add the server to your Claude Code MCP configuration.

Option A — project-level (.claude/mcp.json in your project):

{
  "mcpServers": {
    "swiss-finance": {
      "command": "python",
      "args": ["/absolute/path/to/swiss-finance-data/mcp/server.py"]
    }
  }
}

Option B — global (~/.claude/mcp.json):

{
  "mcpServers": {
    "swiss-finance": {
      "command": "python",
      "args": ["/absolute/path/to/swiss-finance-data/mcp/server.py"]
    }
  }
}

Then restart Claude Code. You can verify the server is loaded with:

/mcp

3. Cursor

Open Cursor Settings → MCP → Add new MCP server and fill in:

Name: swiss-finance
Type: command
Command: python /absolute/path/to/swiss-finance-data/mcp/server.py

Or edit ~/.cursor/mcp.json directly:

{
  "mcpServers": {
    "swiss-finance": {
      "command": "python",
      "args": ["/absolute/path/to/swiss-finance-data/mcp/server.py"]
    }
  }
}

Restart Cursor after saving.

Usage examples

Once connected, you can ask Claude or Cursor Agent directly:

What is the current SNB policy rate?
→ calls get_policy_rate()

Show me the Swiss yield curve.
→ calls get_yield_curve()

What is the EUR/CHF rate?
→ calls get_fx_rate("EUR")

Give me the latest Swiss inflation figure.
→ calls get_inflation_yoy()

Show me the daily returns for Nestlé and Roche over the last 6 months.
→ calls get_smi_returns(tickers=["NESN.SW", "ROG.SW"], period="6mo")

Running manually

cd mcp/
python server.py

The server uses stdio transport (default for MCP). No port is opened.
