## 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**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (delete_watch).
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 74/100
  - 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 8652 tokens (~279/item across 31 items; 26 tools + 5 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 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 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 28 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### `search_jobs` (~1002 tokens)

Search job postings

Search live or recently closed job postings read from employers' own ATS boards, career pages and partner feeds worldwide (strong in Europe, the Gulf, Central Asia and remote roles). Each row: employer, role family, seniority, work mode, locations (ISO codes; a remote role adds hiring_countries), the stated salary or a USD estimate with its method, required technologies, first seen and last verified dates, a trust verdict (ok, stale, ghost) and its Alion page url, where a candidate applies. Newest first, or by pay with sort=salary. Filters combine with AND; an unknown value returns a warning naming what was accepted. Agencies and job boards are left out unless include_agencies=true. Pass next_cursor back for the next page. For counts, pay percentiles or top employers call market_stats instead of paging. Costs 1 unit per call. Docs: https://alion.io/developers/docs

### `resolve_company` (~261 tokens)

Resolve a company

Find the company record behind a domain, a url or a name and learn whether it is alive: its Alion id, canonical domain, industry, size band, headquarters, ATS vendor, how many jobs are open, when the site and the job board were last verified, and coverage - ats_board when its own job board is read directly, partial when only feeds and career pages reach us (open-job counts are then a lower bound). Call this first whenever you only have a name or a domain, then pass the id to get_company or search_jobs. A domain match is exact (or on the registrable domain, e.g. jobs.acme.com -> acme.com); a name match reports its confidence (name_exact, name_prefix, name_partial, with _ambiguous when several records fit) and lists the candidates so you can pick. Costs 1 unit per call. Docs: https://alion.io/developers/docs

Input parameters:

- `domain` (string): Company web domain, e.g. "stripe.com".
- `name` (string): Company name as written.
- `query` (string): Any of the above when you are not sure which it is.
- `url` (string): Any url on the company site or its job board.

Output parameters:

- `candidates` (array)
- `confidence` (string|null): id, domain_exact, registrable_domain, moved, name_exact, name_prefix, name_partial (+ _ambiguous), none
- `match`: The best match, null when nothing fits
- `meta` (object): Quota and credit standing after this call.
- `query` (string|null)

For market maps, competitor and prospect lists, deal flow and technology-adoption research. Each row: headquarters, founding year, startup verdict, newest round and total raised, open jobs and jobs added in 30 days, last verified date. Default order: most recent hiring; sort=recent_funding, open_jobs, score, newest or name. Agencies are left out unless include_agencies=true. Pass next_cursor back for the next page.

### `market_stats` (~527 tokens)

Hiring and pay statistics

Aggregate statistics for a slice of the job market in one call: how much X earns in Y, how many companies hire X, whether demand grows, who hires most, how fast such roles close.

Every block has its sample size n; percentiles are null under 5 postings.

Get answers by webhook

A public https url that receives your agent's events as signed POSTs: message.delivered, message.replied (with the text), message.declined, message.returned, message.expired, agent.paused, agent.blocked. The answer gives the secret for the X-Alion-Signature HMAC once. Pass an empty url to remove it. Docs: https://alion.io/developers/docs

### `watch_search` (~200 tokens)

Watch a search for new results

Save a search of jobs, companies or people and come back for what is new: kind is jobs, companies or people, filters are the arguments of search_jobs, search_companies or search_people (e.g. {"role":"Backend","country":"DE","work_mode":"remote"}). Answers the first page now (newest first, compact) and a watch_id; check_watch with it later returns only the rows that appeared since. Up to 20 watches per agent (an account, a wallet, or a network and client name). Use it for a job hunt, a hiring pipeline or a market you follow. Free. Docs: https://alion.io/developers/docs

Input parameters:

My job matches

The job postings Alion matched to the signed-in account's profile (its /matches feed), newest first: the compact posting with when it was matched and whether the person already saw it on the site.
