Available tools 11

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

private

private_age_distribution

Get business age distribution — how many entities are 0-4, 5-9, 10-14, 15-19, 20-29, 30-39, 40+ years old. Optionally filter by state.

private_browse

Build a list of companies matching criteria rather than looking one up: state, industry (NAICS), entity type, age, city, ZIP. Use it for prospecting, market sizing, or finding every business of a kind in a place. Ask for an industry with the naics filter — 23 is construction, 238 specialty trades, 238160 roofing.

private_ceo_search

Find the chief executive, president, chairman or manager behind a company, or find every company a named executive runs. Use when the question is "who is actually in charge here" rather than "does this company exist". Restricted to executive-level titles; use private_officer_search for any role including directors and secretaries.

private_entity

You have already identified a company and now need the full official record: current status, incorporation date, EIN, registered agent, every officer with their role, addresses, and filing history. This is the record a state government actually holds, so use it to settle questions that web sources disagree about — mirrors frequently report stale status or the wrong registered agent.

private_geography

Geographic distribution of private businesses. Group by city, zip, county, or state. Shows where businesses are concentrated.

private_officer_search

Find which companies a named person is an officer, director or registered agent of. Use it to check whether a counterparty is who they claim, to map the other entities behind one operator, or to find every company a person controls before signing with any of them. Covers 21.2M officer records.

private_owner_operated

Find businesses where an officer is also the registered agent — the filing lists the same person in both roles. This is a succession and acquisition signal: it usually means an owner-operated company with no management layer. Use it to build acquisition target lists or to judge whether a supplier depends on one person. It indicates what the filing says, not legal ownership or control.

private_resolve

Resolve a messy or partial business name to ONE canonical government record, with a computed confidence score (0-1), an ambiguity flag and ranked alternatives. Use this when you have a company name from a document, email or user message and need to identify the actual registered entity. Prefer this over private_search when the goal is identification rather than browsing. If confidence is below 0.6, show the user the alternatives instead of choosing one.

private_search

Find US businesses by name when you do not yet know which one you want. Full-text ranked search over 30.6M entities from 56 state and territory registries. Use it to browse candidates or check whether a name exists at all; use private_resolve instead when you need to identify one specific company. Note: this matches NAMES. There is no industry classification in the search itself, so "roofing" returns companies named "Roofing ...", not every roofer — use private_list with a naics filter for that.

private_stats

Check what this dataset actually covers before relying on it. Returns per-state record counts AND the government source behind each state, which matters: some states are full business registries with officer records, while others (California, Illinois) hold only federal SAM.gov registrants with no officer data at all. Read this before asking who runs a company in a state you have not used before.

private_type_breakdown

Entity type breakdown — how many domestic profit corps, LLCs, LPs, nonprofits, foreign corps, etc. Optionally filter by state.

Companies — questions

Answers built from our own checks of this server.

What can Companies do?

It exposes 11 tools, read directly from the server on our last check. Among them: private_age_distribution, private_browse, private_ceo_search, private_entity, private_geography, private_officer_search and 5 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Companies working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 88 of 91 checks got a reply (96.7%), average response time 619 ms. The bar chart above shows every period we have measured.

How do I connect Companies?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Companies need an API key?

No. Companies completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 11 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Companies?

It answers our handshake in 619 ms on average, which is faster than 16% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
