Model Context Protocol

MCP server for company data — connect Claude and any AI agent.

Netstate runs an MCP server that exposes 128 million US and Canadian company records as tools your AI assistant can call — search, resolve and browse official registers from inside Claude, Cursor or any MCP client. The Model Context Protocol is the open standard for connecting AI systems to external data sources: Streamable HTTP, no key, no registration. Your agent fetches the public records; your people make the decisions.

Connect it Prefer REST?

# One endpoint, no auth https://netstate.co/mcp

{ "mcpServers": { "netstate": { "url": "https://netstate.co/mcp" } } }

Connect Claude and any MCP client

The MCP server speaks Streamable HTTP with no authentication, so AI assistants and agents — like Claude — need nothing more than the URL https://netstate.co/mcp to reach the company data. One endpoint serves every client; add it as a new data source and start querying from a fresh chat.

Claude Code

claude mcp add --transport http netstate https://netstate.co/mcp

Claude Desktop & generic clients

Add to mcpServers in your client config:

{ "mcpServers": { "netstate": { "url": "https://netstate.co/mcp" } } }

Cursor & other MCP clients

Point any Streamable-HTTP MCP client at the URL below — transport Streamable HTTP, no auth header. Then ask a business question in plain language and the agent searches the registers for you.

https://netstate.co/mcp

Smoke test

List the tools straight from the terminal:

curl -X POST 'https://netstate.co/mcp' -H 'Content-Type: application/json' \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

MCP tools for company data

Three MCP tools, backed by the same builders as the REST API — so the company data your agent reads can never disagree with a Netstate profile. The registers behind them span every US state, DC, Puerto Rico and Canada: 61 source registers and 16 federal datasets in one endpoint. Every field is sourced to a Secretary of State or federal filing and refreshed on each register's own cadence — company name and legal status, registration numbers, NAICS industry codes, registered agents, addresses, officers and directors, UCC positions and liens, litigation history and SBA loans.

search_companiesSearch companies
Full-text search across 128 million registered companies in official US and Canadian state registers — by legal name, officer or director name, phone number, email or website. Contact-shaped queries (phone/email/website) resolve through the official records carrying that exact value; the response's matched_by field says which channel matched. Filters mirror the website's facet rail; the response carries up to 25 matching profiles plus facet counts. Facet counts describe every name match (not just the filtered set), so they show which filter values would widen or narrow the search. Records are for human review — not for automated decisions covered by the FCRA.

list_jurisdictionsList jurisdictions & industries
The taxonomy for building queries: countries with regions (and cities when a country+region is given), industries, statuses, and total company count. Call this first to find valid slugs for the other tools.

get_site_infoAbout Netstate
What Netstate is, its pricing plans, API endpoints, FAQ and usage restrictions. Call this to learn what the site offers before using the data tools.

Data access & limits

No key, no API keys, no registration. Fair-use limits at the edge govern access: up to 250 search_companies calls per IP per day; the taxonomy and site-info tools are uncapped.

Also for agents

Discovery starts at /llms.txt; the REST reference lives at /api.md and /api.

Not for FCRA use

No. Netstate is not a consumer reporting agency, and its data may not be used for any purpose covered by the FCRA — decisions about credit, insurance, employment or housing. It is built for research and business due diligence, where your team reviews the records and makes the call.

What can an agent do with it?

Resolve a company to its register entry, pull officers and the registered agent, read UCC liens and secured positions, check litigation history and SBA loans, or map beneficial-owner and officer links across entities — all from public filings, each answer citing its source so you can verify it.

Where does the data come from?

Secretary-of-State registers plus 16 federal datasets, resolved into one entity per company. Netstate is a public-records search engine, not a contact database: it exposes officer, director and agent names and addresses as they were filed, not phone or email dossiers.
