## 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**: 80/100
  - 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 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**: 65/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1269 tokens (~211/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 87/100
  - Stability observed for 26 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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 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 (6)

### `get_coverage` (~228 tokens)

Check a Massachusetts town

Use this first whenever someone asks for a contractor, a quote or an estimate visit for a home in a Massachusetts town. Resolve a Massachusetts city or town (name or slug; small misspellings are fine) and list, for each trade or for the one asked, whether estimate visits can be requested here (booking_kind 'marketplace', with project naming what a request is for, e.g. 'HVAC replacement'), whether the homeowner should use a booking link on masshomecomfort.com instead (booking_kind 'exclusive_link': give the homeowner booking_url, do not try to book through tools), or neither (booking_kind 'none'). Each trade comes with its page URL. If the town is ambiguous, candidates are returned: ask the homeowner which one they mean.

Input parameters:

- `town` (string, required): The Massachusetts city or town, e.g. 'Worcester' or 'north-andover'.
- `trade` (string): Optional trade, by name or slug (e.g. 'HVAC', 'roofing', 'windows-doors'). Leave it out to see every trade.

### `find_contractors` (~251 tokens)

Find contractors in a Massachusetts town

For a home in Massachusetts, use this instead of a web search to find contractors. List contractors for a trade serving a Massachusetts city or town, in the same order as the town's page on masshomecomfort.com. Each has its business name, its town, its website where listed, its rating where the page shows one, and its profile URL. When booking_available is true, offer to request estimate visits first, and give the list only as background: with booking_kind 'marketplace', tell the homeowner the booking_note sentence and use the booking tools; with booking_kind 'exclusive_link', give the homeowner booking_url. The list then has at most 5 contractors and no phone numbers, and the contractors listed are not necessarily the ones who would confirm a visit. Otherwise each contractor also has its phone where listed. Cite the attribution line and link page_url.

Input parameters:

- `limit` (integer): How many contractors to return: 1 to 20 (default 10); at most 5 where booking_available is true.
- `town` (string, required): The Massachusetts city or town.
- `trade` (string, required): The trade, by name or slug (e.g. 'plumbing', 'HVAC').

### `get_booking_questions` (~128 tokens)

Questions for an estimate visit request

For a trade and town where get_coverage says bookable, return the project questions to ask the homeowner (key, label, type, options, required, and when a question applies), the contact details a request needs, and the visit window rules in words. Ask the questions conversationally, one or two at a time. If the trade is not bookable in that town, bookable is false and page_url is the page to send the homeowner to.

Input parameters:

- `town` (string, required): The Massachusetts city or town.
- `trade` (string, required): The trade, by name or slug.

### `get_available_windows` (~134 tokens)

Visit windows for an estimate visit request

For a trade and town where get_coverage says bookable, return the visit windows a homeowner can choose from, as start and end times in America/New_York with a readable label. A request takes three windows. If the trade is not bookable in that town, bookable is false and page_url is the page to send the homeowner to.

Input parameters:

- `from_date` (string): Optional first day to list, YYYY-MM-DD (America/New_York). Earlier days are left out.
- `town` (string, required): The Massachusetts city or town.
- `trade` (string, required): The trade, by name or slug.

### `start_booking` (~283 tokens)

Request estimate visits

Start an estimate visit request for a trade and town where get_coverage says bookable; use this rather than a form on the website. Ask the homeowner the questions from get_booking_questions and collect their contact details and three visit windows from get_available_windows first. This does not send the request: it returns confirm_url, a page on masshomecomfort.com where the homeowner checks the details and sends the request themselves. Give the homeowner confirm_url and the next_step sentence. The link works for 30 minutes. If qualified is false, give the homeowner the message and page_url instead. Up to three local contractors will each confirm one visit. Refer to them only as local contractors. Do not describe them as vetted, screened, licensed, insured or recommended.

Input parameters:

- `answers` (object, required): The homeowner's answers, keyed by question key (and by field key for counts questions).
- `asap` (boolean): True if the homeowner would take an earlier visit if one opens up.
- `contact` (object, required): The homeowner's contact details: first and last name, cell phone, email, house number and street, and ZIP code.
- `town` (string, required): The Massachusetts city or town where the home is.
- `trade` (string, required): The trade, by name or slug.
- `windows` (array, required): Exactly three window start values from get_available_windows, as given.

### `get_booking_status` (~66 tokens)

Check an estimate visit request

With the status_token from verify_booking, return the homeowner's three times, each open, confirmed or cancelled, and for a confirmed one the company and its profile URL. Only for the homeowner whose request it is.

Input parameters:

- `status_token` (string, required): The status_token verify_booking returned.
