openswissdata
The first Swiss MCP server for Claude Code & Cursor.
Plug Swiss federal datasets (TARES, NOGA, FINMA) directly into your AI agent. JSON-RPC 2.0, pre-computed multilingual embeddings, signed cryptographic manifest. Free tier 100 req/day.
Connect openswissdata to Claude Code in 30 seconds.
Step 1 · Add the server
In ~/.claude/mcp.json or via claude mcp add:
{
"mcpServers": {
"openswissdata": {
"url": "https://mcp.openswissdata.com/mcp/jsonrpc",
"transport": "http"
}
}
} Step 2 · Restart Claude Code
The 8 tools will appear automatically in Claude Code's MCP picker (/mcp command).
Step 3 · Test
Try for example: "find the TARES code for 18-carat gold jewellery" and the agent will call tariff_semantic_search automatically.
Similar configuration for Cursor (~/.cursor/mcp.json) and other MCP-compatible clients. Full docs at github.com/openswissdata.
