What is the Openswissdata MCP Server?

The Openswissdata MCP server gives AI agents structured, permission-aware access to Openswissdata through the Model Context Protocol. With 9 pre-built actions, agents can read, create, and update Openswissdata data on behalf of authorized users.

Willow ships the Openswissdata MCP server as part of an enterprise control plane. Every call runs behind SSO (Okta, Azure AD), enforces RBAC and least-privilege at runtime, writes to a full audit trail, and integrates with Splunk and Loki for SIEM visibility. Connect from Claude Desktop, Claude Code, Cursor, ChatGPT, VS Code, n8n, or any custom agent. Install once, distribute org-wide, and see exactly how Openswissdata is being used by every AI agent in your stack.

Tools

Tool

tariff_lookup

Lookup a Swiss customs tariff (HS8) and return the full TARES row including MFN duty, preferential regimes, restrictions and customs relief codes. Always returns a non-official disclaimer that the agent must surface to the end user.
Tool

kyc_check

Search the FINMA registry of supervised entities and the FINMA warnings list by name. Returns up to top_k authorised entities + any matching warning entries. Use this for basic counterparty KYC screening.
Tool

cross_walk

Translate an industry classification code between schemes (NOGA 2008/2025, NACE 2.0/2.1, ISIC 4). Returns all mappings with their type (exact, partial, aggregated, derived) and notes.
Tool

tariff_semantic_search

Semantic search across Swiss customs tariff (TARES) descriptions in French. Uses pre-computed Xenova/paraphrase-multilingual-mpnet-base-v2 embeddings (768d, FR) shipped with the TARES Pro bundle. Returns top-K HS8 codes by cosine similarity. Always inlines a non-official disclaimer.
Tool

classify_text

Classify a free-text business description into top-K NOGA 2025 codes with confidence scores. Uses pre-computed Xenova/paraphrase-multilingual-mpnet-base-v2 embeddings (768d, FR). NACE 2.1 mode falls back to NOGA 2025 in v1 — combine with cross_walk for translation.
Tool

finma_search

Fuzzy search the FINMA registry by name (tolerates typos and legal-suffix variants like 'UBS Switzerland AG' vs 'UBS AG'). Returns top-K matches with confidence score, including LEI/UID where available. Set include_warnings=true to also surface entries from the FINMA warnings list.
Tool

tariff_changelog

Returns the historical changelog of MFN duty rates (and adjacent fields) for a Swiss customs tariff (HS8) code. Window: rolling 12-24 months. Irreplicable by scraping — xtares.admin.ch only serves the current version. Requires `hs8`; optional `since` (ISO date) to bound the window.
Tool

entity_history

Returns the timeline of changes for a FINMA-supervised entity (registration, authorisation type changes, status mutations, address moves, warning-list flag transitions). Keyed by Swiss UID (CHE-xxx.xxx.xxx). Irreplicable by scraping — finma.ch only publishes the current state.
Tool

statent_lookup

Swiss enterprise statistics (STATENT, BFS) for a NOGA 2-digit division and optional canton. Returns count of establishments, jobs, and full-time equivalents (FTE). 2023 data. Always inlines a BFS attribution disclaimer.

Enterprise Governance for Openswissdata

Willow adds the layer Openswissdata and every other SaaS doesn't ship out of the box: every call runs behind SSO (Okta, Azure AD), enforces RBAC and least-privilege at runtime, writes to full audit logs, and detects shadow AI usage across your stack. One MCP gateway. Any agent. Every tool.

Openswissdata MCP Server FAQ

What is the Openswissdata MCP server?

The Openswissdata MCP server is a Model Context Protocol implementation that lets AI agents like Claude, Cursor, and ChatGPT read and write Openswissdata data through a standardized interface. Willow hosts and governs this server so enterprises can roll it out without a security review backlog.

How is Willow's Openswissdata MCP server different from the official one?

The official Openswissdata MCP server is scoped to a single user's account and does not include enterprise governance. Willow's version adds SSO, RBAC, audit logging, shadow AI detection, and centralized control over which actions agents can take across the entire org.

Which AI clients work with the Openswissdata MCP server?

Claude Desktop, Claude Code, Cursor, ChatGPT, VS Code with MCP support, n8n, and any custom agent built with OpenAI Agents SDK, LangChain, Vercel AI SDK, or Anthropic SDK.

Is the Openswissdata MCP server secure? How does Willow handle authentication?

Every call runs behind your existing SSO (Okta, Azure AD). Per-user OAuth scopes the agent to exactly what that user can do in Openswissdata, nothing more. No credentials reach the LLM. Every action writes to an audit trail.

Can I limit which Openswissdata actions agents can take?

Yes. Willow lets you scope agents to specific actions, specific projects, or specific environments. Toggle actions on or off in the dashboard, or enforce policy via infrastructure-as-code through GitHub.

How do I detect shadow Openswissdata MCP servers in my org?

Willow's browser extension and discovery service surface unmanaged MCP servers, skills, and AI agents across the org. If a developer installed an unapproved Openswissdata MCP locally, you'll see it.

What does the Openswissdata MCP server cost?

Pricing depends on org size and deployment model (SaaS, dedicated cloud, self-host). See withwillow.ai/pricing or contact sales for a quote.

How do I install the Openswissdata MCP server with Willow?

Install via the Willow Connect Panel in one click, or paste the JSON snippet above into your Claude Desktop, Cursor, or Claude Code config. SSO and RBAC inherit from your existing Willow setup.
