Endpoint Security46
Transport & Reachability100
Schema Quality & AI Usability74
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 515 tokens (~171/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
  • Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

How do I install the ATS Jobs MCP server?

ATS Jobs is a hosted endpoint at https://ats-jobs-api.groundtruthtools.workers.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 3 exposed · ~392 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
compare_companies ~93

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.

NameTypeReqDescription
companiesarrayyesUp to 20 company board names or careers URLs.
per_companyintegerMaximum postings per company.

No output schema declared.

No examples provided.

find_company_board ~128

Find which applicant-tracking system a company's careers page runs on. Greenhouse, Ashby and Lever 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.

NameTypeReqDescription
companystringyesCompany name or board name, for example 'anthropic' or '1Password'. Case and punctuation do not matter.
limitintegerMaximum matches to return.

No output schema declared.

No examples provided.

list_open_jobs ~171

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.

NameTypeReqDescription
companystringyesA board name ('stripe'), a careers URL ('https://jobs.ashbyhq.com/ramp'), or system:name ('ashby:ramp').
include_descriptionbooleanInclude the full job description. Off by default because descriptions are long; contact details are removed either way.
limitintegerMaximum postings to return.

No output schema declared.

No examples provided.

Common questions

What is the ATS Jobs MCP server?

ATS Jobs is an MCP server listed in the public MCP registry as io.github.groundtruthtools/ats-jobs-mcp. Open jobs read from a company's own careers system: Greenhouse, Ashby, Lever. This page covers its hosted endpoint (https://ats-jobs-api.groundtruthtools.workers.dev/mcp).

Is the ATS Jobs MCP server safe to use?

ATS Jobs scores 63 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the ATS Jobs MCP server expose?

ATS Jobs exposes 3 tools: find_company_board, list_open_jobs, compare_companies. Their descriptions and schemas cost roughly 392 tokens of context every time the server is loaded.

Does the ATS Jobs MCP server require authentication?

No. We connected to ATS Jobs without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the ATS Jobs MCP server still maintained?

ATS Jobs is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
