At a glance: 40+ servers across 8 subcategories. 5 official government agency servers. Rating: 4/5.
Five government agencies have released official MCP servers — more institutional adoption than any other vertical category. The U.S. has the deepest coverage, from official Census Bureau and GPO servers to a community mega-aggregator with 188+ tools across 36 APIs.
Official Agency Servers
- GovInfo MCP (U.S. GPO) — first official U.S. federal MCP server. Bills, laws, Federal Register, CFR, presidential documents. Certified digital repository.

What's Missing
Municipal/city services, voting/elections admin, social services, immigration, public transit, emergency management, most G20 nations.
The Bottom Line
Rating: 4/5 — Institutional adoption by five government agencies is remarkable for a protocol this young. Legislative and procurement coverage is comprehensive. The 188-tool US government server alone justifies the category. International coverage beyond US/France/India is thin.
