Overview

AI-generated overview

Remote MCP server for company data from official sources: job boards, business registers, DNS, SEC filings, plus general web reading tools.

What you can do
  • Find and read job boards: locate a company's ATS board, list open jobs, compare up to 20 companies, track daily job changes and summarize hiring.
  • Look up companies: state register records for new businesses, registry search by country, VAT validation, SEC financials, federal contracts.
  • Inspect domains and sites: RDAP registration, DNS, email provider, SPF/DMARC, tech stack detection.
  • Read the web: pages and PDFs as markdown, named fields extracted as JSON, email address checks.
  • Search external catalogues: scholarly papers, Hacker News, App Store apps, and paid x402 API endpoints.
When to use it
Useful when an assistant needs verifiable company facts — hiring activity, register entries, financials, domain and tech details — or general page reading and extraction, without building scrapers or vendor integrations.
Requirements
Remote Streamable HTTP endpoint; no install. No account or key needed for 10 free calls a day; beyond that, pay per call with x402 (USDC on Base) or a prepaid key. extract_page requires an API key. A small local PyPI edition covers only the three job tools.
Before you install
Calls beyond the free daily quota cost money, either per call in USDC or via a prepaid key; extract_page draws on a paid balance. Tools are described as read-only, but read_page and extract_page fetch third-party pages, so requested URLs and extracted content leave your machine. No personal data is returned by design.

Installation

In SourceWeft

  1. Open Company Facts in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.companyfacts%2Fcompany-data/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

ats-jobs-mcp: Company Facts

An MCP server for company data read from the official or original source. Newly formed US businesses straight from state registers, with their website found only on proof. A company's register entry, tech stack, DNS and email provider, SEC financials and open jobs, each with a link to where it came from.

The full server runs remotely at https://companyfacts.dev/mcp with 20 tools and nothing to install. This PyPI package is the small local edition: the three job tools, run on your own machine.


Use it with no install

Point any MCP client that speaks Streamable HTTP at the URL:

json
{  "mcpServers": {    "company-facts": {      "url": "https://companyfacts.dev/mcp"    }  }}

No account and no key: 10 free calls a day. Past that, pay per call with x402 (USDC on Base) or use a prepaid key (see https://companyfacts.dev/pricing). A call that finds nothing is not charged.

The same tools answer plain HTTP, for agents that do not speak MCP:

  • GET https://companyfacts.dev/openapi.json for a tool-calling agent
  • GET https://companyfacts.dev/llms.txt for a model reading the service in prose
  • GET https://companyfacts.dev/v1/new-businesses?states=CO&mode=new

Company tools (remote)

ToolWhat it returns
new_businessesNewly formed businesses from the official Secretary of State registers of New York, Colorado, Oregon, Connecticut and Pennsylvania, in one record format. Feed by formation date, search by name, or look up by state entity number (KYB checks). Each record carries the company's website when one was found with proof, else says none was found.
company_searchSearch every company we track: filter by state, city, name, formation date, technology on its site (Shopify, WordPress, ...), whether it publishes a phone, role inbox or contact page, and hiring. A search with no match is not charged.
company_lookupOne company from its domain: registrar, DNS and email provider, website tech stack, hiring from its own job board, plus its official register entry or SEC figures when you give name and country or a ticker.
search_company_registryOne country's official company register by name (UK, Norway, France, Finland, Czechia, Slovakia, Ireland, Australia, or GLEIF worldwide), in one shape.
sec_financialsUS public company financials from SEC EDGAR XBRL.
validate_vatAn EU VAT number checked against the European Commission's VIES service.
domain_lookupRegistration (RDAP), DNS records, email provider, SPF and DMARC for a domain.
detect_tech_stackThe technologies behind a web page, each with its evidence.
federal_contractsAwarded US federal contracts from USAspending.

Websites are attached to new businesses only on proof: the site's own pages must show the exact legal name and the same city, state or ZIP as the register. Records never carry officers, directors, individual registered agents, emails, phones or street addresses.

Job tools

ToolWhat it returns
find_company_boardWhich applicant-tracking system a company's careers page runs on, and its board name.
list_open_jobsEvery open job at one company, read from its own Greenhouse, Ashby, Lever or Workable board.
compare_companiesOpen jobs across up to 20 companies in one schema.
job_changesJobs newly posted, taken down, reopened or edited, day by day, from a daily record of every board.
hiring_summaryOne company's hiring at a glance: roles by department and place, remote share, salary ranges, recent openings and closings.

The vendors publish open job board APIs, and all of them are useless unless you already know the company's board name. None publishes a directory of its customers, so this carries one: 8,532 boards on the remote server, each confirmed against the vendor's own API.

Other tools (remote)

read_page (a web page or PDF as markdown), extract_page (named fields from a page as JSON, paid only), check_email (syntax, mail servers, disposable and role flags), search_papers (OpenAlex), search_hacker_news, app_store_lookup.

Every tool is read-only and declares a title and readOnlyHint.

Salaries, parsed, and refused when unclear

Ashby prints pay as "$211.4K - $290.6K". Greenhouse prints it in cents, sometimes as several bands at once. Both are turned into numbers:

json
"salary_min": 211400.0, "salary_max": 290600.0,"salary_currency": "USD", "salary_text": "$211.4K - $290.6K"

The parser refuses more often than it guesses, deliberately:

  • $50 - $80 / hour gives no salary. An hourly rate is a different quantity and reporting it as annual would be a confident lie.
  • 600 000 kr gives no salary. kr is Swedish, Norwegian and Danish.
  • 0.5% - 1.75% - Offers Equity gives no salary. Equity is not pay.
  • Bands in two currencies are never spanned into a range that exists nowhere.

salary_text always keeps what the employer actually wrote.

No personal data

Recruiter names are never returned. Email addresses and phone numbers are removed from job descriptions. Unlisted Ashby postings are dropped, because Ashby's documentation says they should not be shown publicly.

Or install the local job edition

bash
pip install ats-jobs-mcp
json
{  "mcpServers": {    "ats-jobs": {      "command": "ats-jobs-mcp"    }  }}

The local edition has find_company_board, list_open_jobs and compare_companies over a bundled directory of 7,479 Greenhouse and Ashby boards (Lever by name, for example lever:spotify). It is free, runs on your machine, and takes no cut of anything.

Python and LangChain

  • pip install groundtruth-company: a Python client for the company tools.
  • pip install langchain-groundtruth: the same tools as LangChain tools.

Relation to the Apify Actors

The same job parsing runs as an Apify Actor at apify.com/groundtruth/ats-job-listings. tests/test_core_parity.py fails if the two copies of the parsing logic drift apart.

Licence

MIT. Job postings belong to the employers who published them. Register records belong to the states that publish them.

find_company_board

Find a company's job 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.

Parameterslimitcompanyrequired

list_open_jobs

List a company's 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.

Parameterslimitcompanyrequiredinclude_description

compare_companies

Compare several companies' jobs

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.

Parameterscompaniesrequiredper_company

job_changes

Jobs opened, closed or changed

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.

Parametersqkindslimitsinceuntiloffsetcompanies

read_page

Read a web 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.

Parametersurlrequiredmax_chars

extract_page

Pull structured data from a 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.

Parametersurlrequiredfieldsschemainstructions

check_email

Check an email address

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.

Parametersemailrequired

domain_lookup

Look up a domain (registration, DNS, email provider)

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.

Parametersdomainrequired

detect_tech_stack

Detect a website's 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.

Parametersurlrequiredmin_confidence

validate_vat

Validate an EU VAT number

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.

Parametersvatrequired

search_company_registry

Search an official 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.

Parametersnamerequiredlimitstatecountryrequired

search_papers

Search academic 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.

Parametersdoismodesortquerysourceto_yearfrom_yearcited_workwork_typesinstitutionmax_resultssearch_scope+4 more

search_hacker_news

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.

Parametersmodequerydate_tosort_bydate_frommax_itemssearch_instory_idsstory_tagmin_pointscontent_typemin_comments+1 more

sec_financials

SEC financials and screener

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.

Parametersmodelimitordermetricperiodcompanymax_valuemin_valueperiod_type

hiring_summary

Summarise a company's hiring

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.

Parametersdayscompanyrequired

federal_contracts

Federal contract awards and recompetes

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.

Parametersmodelimitagencykeywordend_datemin_amountstart_dateaward_typesexpiring_after_daysexpiring_within_days

app_store_lookup

Look up Apple App Store apps

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.

Parametersidsmodepagetermchartcountrycategorybundle_idmax_resultsreview_sortinclude_description

company_lookup

Everything public about a company

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.

Parametersnamedomainrequiredtickercountry

new_businesses

Newly formed US businesses and state register lookup

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.

Parametersmodenamelimitsinceuntilstatesstatusentity_typeentity_numbers

find_x402_api

Find the best x402 API for a task

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.
