Do I need a Census Bureau API key?

Yes, you will need to provide a free API key from the Census Bureau to authenticate the requests.

Which AI clients can I use with this MCP?

You can use this with any MCP-compatible client, including Claude, Cursor, Windsurf, and VS Code.

Can I get data for specific cities?

Yes, the get_population_by_city capability allows you to retrieve population data for incorporated cities and Census Designated Places.

Does this include business data?

Yes, the get_business_patterns capability provides data on establishments, employees, and payroll from the County Business Patterns dataset.

How is the data hosted?

Vinkius hosts and manages the MCP, so you don't have to run any local code or manage the connection yourself.

Why does it require an API key?

While the SEC and Treasury APIs do not require keys, the Census Bureau requires a free API key to handle the massive volume of hyper-local data (thousands of variables across millions of geographies). The key prevents rate limiting and ensures stable connections.

What geographies can I query?

This MCP limits the main built-in endpoints to State, County and Place (cities). Detailed geometries like zip-codes, tracts, or congressional districts can be queried utilizing the query_census custom capability.

Is Puerto Rico included?

Yes! Puerto Rico is treated internally as state FIPS code 72.

Waiting for input…

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

One connector, every AI

U.S. Census Bureau works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put U.S. Census Bureau to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of U.S. Census Bureau, so you can see the experience inside your AI.

It does not authenticate your account with U.S. Census Bureau. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
