Frequently Asked Questions

What are open data MCP servers?

Open data MCP servers wrap APIs that publish non-secret information: census figures, weather archives, transit schedules, and similar sources. Authentication is often minimal, but respect each publisher's attribution requirements.

Is the data always free?

Many sources are free; some require API keys with usage tiers. Read each provider's terms — throttling and attribution rules still apply even when the underlying data is public.

Can I rely on open data for compliance?

Open data helps with context, not legal determinations. Verify freshness, jurisdiction, and official sources before basing regulated decisions solely on tool output.
