## 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 2026-08-20.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - 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**: 81/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 366 tokens (~122/item across 3 items; 3 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 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.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (3)

### `count_businesses` (~154 tokens)

Count verified US B2B businesses in the LeadQuasar database matching an industry, state and/or city, with how many have an email address and a phone number. Use this to answer questions like 'how many managed service providers are there in Texas' or 'how many dentists in Chicago have a business email'. Returns real counts from 7.5 million live records.

Input parameters:

- `city` (string): US city name.
- `industry` (string): Industry or business type in plain words, e.g. 'managed service provider', 'dentist', 'HVAC contractor'. Matched against industry and category.
- `state` (string): US state, either full name ("Texas") or two-letter code ("TX").

### `search_businesses` (~127 tokens)

Return a sample of matching businesses with industry, location and data-quality signals. Contact details (name, company, email, phone, address) are never returned by this tool — it shows what exists and how reachable it is, not who to call.

Input parameters:

- `city` (string): US city name.
- `industry` (string): Industry or business type in plain words.
- `limit` (number): How many rows to return, 1-25. Defaults to 10.
- `state` (string): US state, either full name ("Texas") or two-letter code ("TX").

### `list_industries` (~36 tokens)

List the industries LeadQuasar covers and how many verified businesses each holds. Use this first when unsure what industry wording will match.
