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:

{
  "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:

"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

pip install ats-jobs-mcp
{
  "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
