## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 83/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 84/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1538 tokens (~219/item across 7 items; 7 tools + 0 resources), over budget; trim descriptions and params.
  - Tools include usage examples.
- **Stability & Change Management**: 40/100
  - Stability observed for 12 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (7)

### `company_hiring_brief` (~216 tokens)

Company hiring brief

Best for: what one company is hiring for and how fast, such as "what is Snap hiring for?" or "is Airbnb hiring faster this month?".
Returns: open roles, shares remote and with a salary, top departments and countries, the 5 newest roles, and roles opened and closed over 7, 30 and 90 days and per week once the board has a day of history. The board token goes into watch_new_roles. A paid call adds hiring_velocity: new roles per week for 13 weeks, a trend and a percentile among tracked companies.
Input tips: {"company": "https://snapchat.wd1.myworkdayjobs.com/snap"}, an "ats:slug" token or a company name.
Not for: lists of individual jobs with filters, or people at the company.

Input parameters:

- `company` (string, required): A careers page URL, an "ats:slug" token such as "greenhouse:airbnb", or a company name or domain such as "stripe.com".

Output parameters:

- `api_version` (string): Date of this answer's shape; it changes only when a field is removed or changes meaning.
- `as_of` (string): ISO 8601 time the data was published by its source or fetched from it. A cached answer keeps the time of its fetch.
- `ats` (string)
- `board` (string): The ats:slug token; pass it to watch_new_roles to follow this board.
- `company` (string)
- `countries` (array)
- `departments` (array)
- `hiring_velocity` (object|null): Paid calls only. New roles per ISO week (Monday dates) for the company's tracked boards, each role once on the day its board says it was posted (Greenhouse, Lever, Ashby) or first seen: the last 7 da…
- `hiring_velocity_hint` (string): Present instead of hiring_velocity on a call that was not paid: how to get it.
- `history_days` (integer): Days of history kept for this board.
- `newest` (array)
- `note` (string)
- `open_roles` (integer)

- `source` (object): Who the data comes from, to cite and to check it against.
- `untrusted_source` (boolean)
- `velocity` (array): Roles opened and closed over each window (7, 30 and, from the history store, 90 days), from daily reads of this board; a window starts no earlier than the first read, and the list is empty until the…
- `weekly` (array): Roles opened and closed per week (Monday dates, oldest first, up to 13), for boards the history store reads daily.

### `watch_new_roles` (~210 tokens)

Watch companies for new and closed roles

Best for: following companies over time, such as "watch Stripe and Ramp and tell me about new roles".
Returns: a watch_key, then on later calls the roles opened and closed since the last call (up to 100 of each listed, all counted). The first call is a baseline: it records the open roles and reports none as new.
Input tips: {"companies": ["greenhouse:airbnb", "lever:spotify"]} to start; {"watch_key": "hs_..."} to check, plus companies to add (at most 25).
Not for: a one-off look at one company (use company_hiring_brief).

Input parameters:

- `companies` (array): Careers page URLs, "ats:slug" tokens or company names, such as ["greenhouse:airbnb", "https://jobs.lever.co/spotify"]. Added to the watch.
- `watch_key` (string): The watch_key an earlier call returned. Leave it out to start a new watch.

Output parameters:

- `api_version` (string): Date of this answer's shape; it changes only when a field is removed or changes meaning.
- `as_of` (string): ISO 8601 time the data was published by its source or fetched from it. A cached answer keeps the time of its fetch.
- `baseline` (boolean): True on a watch's first read: every open role is recorded and none is reported as new. A company added later is recorded the same way on its first read.
- `boards` (integer)
- `closed_count` (integer)
- `closed_roles` (array)
- `failed` (array)
- `new_count` (integer)
- `new_roles` (array)

- `source` (object): Who the data comes from, to cite and to check it against.
- `untrusted_source` (boolean)
- `watch_key` (string): Keep it: it is the only way to read this watch again. Calls with it return changes since the last call.

### `watchlist_digest` (~135 tokens)

Watchlist hiring digest

Best for: which watched companies are hiring fastest, such as "who on my watch is hiring most this week?".
Returns: per company on the watch, open roles and roles opened and closed over 7 and 30 days, fastest first. It reads the watch's last read and the daily snapshots, never a job board, so call watch_new_roles first for fresh counts.
Input tips: {"watch_key": "hs_..."}.
Not for: starting a watch (use watch_new_roles).

Input parameters:

- `watch_key` (string, required): The watch_key an earlier call returned. Leave it out to start a new watch.

- `source` (object): Who the data comes from, to cite and to check it against.

### `segment_hiring_ranking` (~223 tokens)

Fastest-hiring companies in a segment

Best for: who is hiring fastest in a market, such as "which companies added the most sales roles in Berlin this week?".
Returns: companies ranked by new roles over 7 days, each with boards, open roles, baseline weekly average, ratio and a spike flag, plus as_of and the method.
Input tips: {"segment": {"function": "sales", "city": "berlin"}}, {"segment": {"ats": ["greenhouse"]}} or {"segment": {"companies": ["stripe.com"]}}; no segment ranks every company. A function or city segment is this week's leaderboard list (at most 50). Country and size are not filters.
Needs: an API key on the segment plan (49 USD a month); else subscription_required with plan_page.
Not for: one company's detail (use company_hiring_brief).

Input parameters:

- `limit` (integer): Companies to return, fastest first. Default 50.
- `segment` (object): Which companies to rank. Leave it out to rank every company the history store reads.

Output parameters:

- `api_version` (string): Date of this answer's shape; it changes only when a field is removed or changes meaning.

Input parameters:

- `keyword` (string): Optional: one keyword. Searched together with query and task.
- `query` (string): Optional words or a task to search for, such as "vat number". Omit query, task and keyword to list every tool.
