    How to choose the best business entity search tool or MCP for you

    Which register

    A company sits in the register of the state or country where it was formed. A company formed in Delaware shows up in California's register only if it also registered to do business there, so search the state of formation first.

    Name or number

    A registration number gives one exact match. A name gives ranked candidates, so check the address and dates before your agent picks one.

    What the register publishes

    Some registers publish officers, owners and filings; others only the name and status. Run the coverage tool first, so your agent doesn't look for data a register doesn't have.

    Why use Agensi instead of each register's own website?

    Every state and country runs its own register, with its own website, search rules and formats. With Agensi your agent searches many of them through one connection, gets the same fields back for each and pays per lookup from one balance, with no accounts or API keys. It runs without asking while your balance covers it, then tells you what it cost. Set limits or have it ask first in Dashboard → Balance.

    When another way is the better choice. For certified documents, such as a certificate of good standing, or to file or change anything, use the register's own site. If a state isn't covered yet, search its Secretary of State website directly.

    Set up in your AI agent

    Connect your AI agent to Agensi once, sign in and click Allow. After that it can use every tool: it runs one from your balance and tells you what it cost. No API keys or provider accounts.

    1. Open Settings, then Connectors, then Browse connectors and add Agensi (or Add custom connector and paste https://mcp.agensi.io/mcp/auth).
    2. Sign in to Agensi and click Allow. One agent per account: connecting a new one disconnects the old one.
    3. Ask for what you want, for example: "Use Agensi to check our new vendor [company] in [state]: is it active, who are the officers, and does the register match the details they sent us?" Top up from $5 if your balance is low; failed uses are free.

    Grok, VS Code, GitHub Copilot, Cline, Kiro and other agents with remote MCP and sign-in work too: see the setup guide.

    Combine business entity search tools with skills

    Business entity search MCP: frequently asked questions

    Each US state keeps a register of the companies formed or registered there, usually run by its Secretary of State. A business search finds a company by name or file number and shows its legal name, status and key dates. Through Agensi your AI agent can search many of these registers for you.

    Many US states, including Delaware, California, New York and Texas, plus national registers in Europe and beyond, such as the UK's Companies House. Coverage changes, so ask your agent to run the coverage tool first: it lists every register and what each one publishes.

    It comes from the official registers, read through third-party data providers, and shows what each register publishes, which can lag behind recent filings. For legal proof, such as a certificate of good standing, order the document from the register itself.

    Yes. It can search and fetch records one company at a time or work through a vendor list. Searches across many large registers can time out, so give the state or country for each company when you know it.
