TheirStack

Official MCP Free to start Signals & Intent RESEARCHED Checked 2026-09-07
RESEARCHED Facts from public sources with URLs. No usage claims. Nobody has run this tool. The other tier is BENCH-TESTED, which means Andrew personally ran the tool on a stated date and cannot be bought at any price. Across the whole directory that count is 1.

Vendor: https://theirstack.com · entry id 05-theirstack · source 05-signals-intent-abm.md line 544

What it does
Tracks 233M+ job postings across 195+ countries and 33,000+ technologies to detect hiring signals, technographic footprint, and buying-intent signals (job-posting keywords implying a company has or needs a specific type of software).
AI features, separated from automation with an AI label on it
Primarily rules/keyword-based signal detection (job posting text matched to technology/problem keywords) - data aggregation, not core ML. Three separate MCP servers are an LLM-agent access layer over the same structured datasets, not a new detection method.
RevOps role
Hiring/technographic/intent signal feed used to build outbound target lists based on what companies are hiring for or which tech-stack gaps they have.

The vendor ships and maintains the server itself. A wrapper built by Zapier, Composio or a similar third party does not count as official. The status was established by hand on 2026-09-07. On 2026-09-04 the recorded URL served a documentation page, not an MCP endpoint. That is where to read about the server, not where to connect to it. An agent needs the second.

Catalogue shape
a fixed catalogue the vendor publishes

The harvest recorded this server against the cross listing TheirStack in Data & Enrichment. It is the same server, so the list is shown here rather than left blank.

A tool below is one the server NAMES. Nobody has called it. That is the same two tier honesty rule the rest of the directory runs on: a named tool is research, and BENCH-TESTED stays the only claim that anybody ran anything.

  • search_companies
    The search_companies tool lets you find companies that use a particular technology, filtered by location, size, or industry.

  • search_jobs
    Find jobs by title, location, salary, seniority, technology, or any combination

  • technographics
    Your AI assistant calls the technographics tool to get any company's full technology stack, categorized by type, with detection dates and confidence signals.
    evidence: in the vendor docs · calling it reads

141 of the 741 entries that record an official or community MCP server carry a harvested tool list. The other 600 are unmeasured, which is not the same as empty. Harvest last run 2026-09-27. Every name across every server is on the tools index.

Command line

No CLI found by the 2026-09-27 harvest across vendor docs, npm, PyPI, Homebrew and GitHub. That is a probe result, not proof of absence.

API documentation

No documentation URL recorded.

727 of 1252 entries are in the same position. Blank is legal and it is published as blank.

GitHub health

Not measured. github_url, github_stars, github_last_commit and github_archived are null on every entry in this build.

The refresh rail specced in SPEC section 7.2 has not been run. An unstamped star count is a lie, so nothing is shown rather than something stale.

On GitHub

No GitHub organisation could be tied to theirstack.com with evidence on 2026-09-08.

Recorded by the harvest: github candidates were seen but none passed the evidence rules.

1 candidate account seen and rejected by the evidence rules: TheirStack. A name match alone is never accepted; the account has to point at the vendor domain.

Jobs it can do

A job tag means the vendor says the tool does this. It is not a test result, not proof the capability is reachable through the tool's MCP server, and not proof it is available on the gate this entry records.

Tagged by machine-pass on 2026-08-25 against the closed 56 job vocabulary. 271 of 1,252 entries carry at least one tag; 849 tags are assigned in total.

Canonical page

What that listing says it does: A job-postings and technographic-data API that tracks live job listings and the tech stack/hiring signals behind them across 195 countries (claims 223M+ jobs, 352K+ sources), queryable for GTM timing/intent signals.

16 of the 1252 entries are cross listed like this. They are why the entry count is 1252 and the unique product count is 1236. The canonical home is declared in INDEX.md, not chosen by the parser.

Notes, verbatim from the file
Free trial plus credit-based pricing from $49/mo (API credits) up to $5,500/mo; one-time credit packs $109-$999; a full "talk to sales" enterprise tier exists for the complete datasets. Three separate MCP servers (jobs, technographics, buying intent) rather than one unified server - see Sweep notes for MCP-of-the-Week candidacy. 2026-09-07: Same first-party endpoint as the other TheirStack entry: DNS-verified registry namespace com.theirstack, 401 invalid_token to an MCP initialize on the trailing-slash path (https://api.theirstack.com/mcp/).
