Available tools 21

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

company
company_lookup
One company in one call, from its domain: registrar, DNS and email provider, the website's tech stack, and hiring from its own job board (open roles by department and place, salary ranges, roles opened or closed lately). Add name and country for the official register entry, or ticker for SEC figures. Each part links to its source; a part with nothing to report says why.
company_search
Finds companies across everything we track: newly formed New York, Colorado, Oregon, Connecticut and Pennsylvania businesses with a website found with proof, and every FDIC-insured bank in any state. Filter by state, source, city, name, formation date, technology on their site (for example Shopify or WordPress), whether they publish a phone, role inbox or contact page, and hiring. Returns register details, website, technologies and job board, newest first. No match is never charged.
find_company_board
Find which applicant-tracking system a company's careers page runs on. Greenhouse, Ashby, Lever and Workable all publish open job board APIs, and all of them are unusable unless you already know the company's board name. None publishes a directory of its customers, and none could, since no vendor knows about the others. Use this first when you have a company name rather than a careers URL.
search_company_registry
Searches one country's official company register by name and returns registered companies in one consistent shape: number, legal name, status, legal form, dates, town and postcode, and a link to the register entry. Covers GB, NO, FR, FI, CZ, SK, IE, AU, the worldwide LEI register, and US entities in any state that hold an LEI (with their state filing number). Companies only, no directors or contact details.
app
app_store_lookup
Search the Apple App Store, look apps up by id or bundle id, read customer reviews, or get the top free, paid and grossing charts, per country. Returns name, developer, price, rating, rating count, version, genres and the App Store link.
compare
compare_companies
Open jobs across several companies at once, in one schema. This is the thing no single applicant-tracking system can do: each vendor only knows about its own customers. Companies on different systems come back with the same field names. One company failing does not lose the others.
detect
detect_tech_stack
Fetch one web page and report the technologies behind it (CMS, ecommerce platform, analytics, CDN, web server, frameworks, payment processors, email provider) with a confidence and the evidence for each. Reads HTML, headers, cookies and DNS from one page load; it cannot see what only a running browser reveals.
domain
domain_lookup
For one domain: whether it is registered, its registrar, created, updated and expiry dates, status codes and nameservers (from the registry's RDAP server), plus its A, AAAA, MX, NS and TXT records, the email provider behind its MX, and whether it publishes SPF and DMARC. No registrant names or contact details are returned.
email
check_email
Is this address worth sending to: syntax, whether the domain exists and has mail servers, and whether it is a throwaway, role (info@, sales@) or free-provider address. It never contacts the mailbox, so a missing mailbox at a real domain still passes, and the answer says so.
extract
extract_page
Read a web page and return the named fields as JSON, using only what the page states; a value the page does not give comes back empty rather than guessed. Name fields, or pass a JSON Schema, or neither for a title, summary and key points. Needs an API key (5 calls from its balance); a failed extraction is refunded.
federal
federal_contracts
Searches awarded US federal contracts on USAspending.gov by agency, keyword and dollar amount, largest first. Recompete mode instead lists contracts expiring soonest within a window (set min_amount to keep the search narrow), with the incumbent and days until expiry. Every record links to the official award page.
hacker
search_hacker_news
Search Hacker News stories and comments with date, points and comment-count filters, read the live front page and the top, best, new, ask and show lists in rank order, or read whole comment threads. Every item links back to news.ycombinator.com.
hiring
hiring_summary
One company's hiring at a glance: open roles counted by department and by location, remote share, salary ranges per currency where the job board publishes pay, and which roles opened or closed in the last 7 or 30 days from a daily record of every board. Reads the company's live Greenhouse, Ashby, Lever or Workable board. Give a company name, board name or careers URL.
job
job_changes
What changed in hiring, day by day: jobs newly posted, taken down, reopened, or edited (title, location or salary), read daily from every job board in the directory. Call it each day with since set to the last day you saw, rather than re-reading every board. Omit companies for the whole market, or filter by kind and title words.
new
new_businesses
Searches the official Secretary of State business registers of New York, Colorado, Oregon, Connecticut and Pennsylvania, in one record format. mode new is a feed of entities formed in a date window, newest first: use it for new-business leads (LLCs and corporations that just registered) and prospecting. mode search finds entities by legal name and mode lookup by the state's own entity number: use them for KYB (know your business) checks on a supplier or counterparty, to confirm it exists, its type, status (active, delinquent, inactive) and formation date. Every record links to the state's own data row. Never returns officers, directors, individual registered agents, emails, phones or street addresses: business city, state and ZIP only. Each record carries the company's website when one was found with proof (its own pages show the exact legal name and the same city or state), else 'no website found'. New York, Oregon and Pennsylvania publish active entities only, so a missing entity there may be inactive or unregistered. Pennsylvania publishes monthly, so its newest entities are weeks old. If one state fails the others still return and the failure is listed in missing.
open
list_open_jobs
Every open job at one company, read from its own careers system. Returns title, department, location, employment type, workplace type, posted date, a parsed salary range where the employer publishes one, and a verify_url pointing at the employer's own advert. Salaries are refused rather than guessed: an hourly rate, an ambiguous currency, or bands in two currencies all yield no figure, and salary_text keeps whatever the employer wrote.
page
read_page
Any public web page or PDF as clean markdown, with its title and final URL after redirects, plus the page's schema.org data (prices, dates) when it has any. robots.txt is honored. Some sites refuse automated readers; those calls fail with the reason and cost nothing.
papers
search_papers
Search the OpenAlex catalogue of scholarly papers by keyword, look papers up by DOI, list the papers that cite one work, or list a university's or journal's papers. Returns title, authors, year, citation count, DOI, abstract and a free full-text link when one exists.
sec
sec_financials
Reads US public company financials from SEC EDGAR XBRL. Company mode returns one company's reported history of a metric (revenue, net income, assets and 20 more, or any us-gaap tag) by ticker or CIK. Screen mode ranks every filer on one metric for one calendar period. Every figure carries period_type and a link to its filing. Reports figures, not advice.
validate
validate_vat
Checks one VAT number against the European Commission's VIES service and returns whether it is a live registration and, where the member state shares it, the registered name. Covers the 27 EU states and Northern Ireland (XI). A busy or down member state is reported as an error, never as an invalid number.
x402
find_x402_api
Say what you need in plain words ('verify an email', 'read a web page', 'company record for a domain') and get the x402 endpoints that do it, best first, ranked only on public facts: wallets that paid it more than once in the last 30 days (Coinbase's CDP catalog), whether it answered our unpaid request with a 402 last night, its price, and PayAI's uptime. Each result has the price, networks, method, and links to re-check every number. No match is never charged.

Company Facts — questions

Answers built from our own checks of this server.

What can Company Facts do?
It exposes 21 tools, read directly from the server on our last check. Among them: app_store_lookup, check_email, company_lookup, company_search, compare_companies, detect_tech_stack and 15 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 Company Facts working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 196 ms. The bar chart above shows every period we have measured.
How do I connect Company Facts?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Company Facts need an API key?
No. Company Facts completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 21 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Company Facts?
It answers our handshake in 196 ms on average, which is faster than 72% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Company Facts open source?
The code is open source: it is published under the MIT licence, written in Python, 1 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at companyfacts.dev, which runs on its operator's own terms.
