## 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 2026-09-27.

- **Endpoint Security**: 74/100
  - 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.
  - 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**: 77/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 972 tokens (~121/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 95/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 86% 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 8 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 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).

## Install

### How do I install the contractors.fyi MCP server?

contractors.fyi is a hosted endpoint at https://contractors.fyi/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.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-09-27 (score 72, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-09-26 (score 71, 0)

## MCP tools (8)

### `list_coverage` (~43 tokens)

List cities and kinds of work

Which cities and kinds of work contractors.fyi covers, with the dates each list covers. Call this before the other tools to get valid city and kind_of_work values.

### `find_contractors` (~136 tokens)

Find ranked contractors

Contractors ranked by how many jobs of this kind their city permit record shows. Returns name, license where the state publishes one, job count, typical stated job value, the ZIP codes they work in most, and a profile URL. Ranking is by volume on the public record, not quality or reviews.

Input parameters:

- `city` (string, required): City id from list_coverage, e.g. los-angeles, new-york, austin
- `kind_of_work` (string, required): Kind of work, e.g. roofing, solar, adu, remodel
- `limit` (integer): How many to return, up to 25

### `project_cost` (~126 tokens)

Job value on permits

What city permits for this kind of work stated as the job value: median and middle half, with the number of permits and their dates. Give a ZIP to get that ZIP's figure where the site publishes one. The value stated on the city permit, not the price paid.

Input parameters:

- `city` (string, required): City id from list_coverage, e.g. los-angeles, new-york, austin
- `kind_of_work` (string, required): Kind of work, e.g. roofing, solar, adu, remodel
- `zip` (string): Five-digit ZIP code

### `permit_timeline` (~101 tokens)

How long permits take

Days from permit application to issue, and from issue to final inspection, from the dates on city permits, with the number of permits and the dates they cover. Final-inspection times count finished jobs only.

Input parameters:

- `city` (string, required): City id from list_coverage, e.g. los-angeles, new-york, austin
- `kind_of_work` (string, required): Kind of work, e.g. roofing, solar, adu, remodel

### `search_contractor_records` (~67 tokens)

Search contractors by name

Look a contractor up by business name across every city covered: the city, how many permitted jobs are on its record there, and its profile URL. This searches the permit record; it does not verify a license today.

Input parameters:

- `name` (string, required): Business name or part of it

### `solar_estimate` (~244 tokens)

Solar size, price and payback

Size a home solar system from the monthly electric bill (or its kWh, or, with neither, the home and what runs on electricity), plus anything the home plans to add such as electric cars, then give the price range homeowners in that city paid for a system that size (Berkeley Lab records, before any tax credit, no battery), yearly savings and payback. Output per kW, heating and cooling use and the default price per kWh are rough city figures.

Input parameters:

- `city` (string, required)
- `electric_cars` (integer)
- `home_size` (string): small: under 1,500 sq ft; medium: 1,500 to 3,000; large: over 3,000
- `miles_per_car` (number): Miles a year, each car
- `monthly_bill` (number): Monthly electric bill in dollars
- `monthly_kwh` (number): From the bill; replaces the estimate
- `price_per_kwh` (number): Dollars per kWh from the bill; default is a typical city figure
- `uses` (array): What runs on electricity besides lights, fridge and outlets

### `check_solar_quote` (~103 tokens)

Check a solar quote

Where a solar quote's price falls among what homeowners in the same city paid for a system of the same size (Berkeley Lab records, homeowner-owned systems, no battery, before incentives): a percentile, the local typical price and range, and the quote's price per watt.

Input parameters:

- `city` (string, required)
- `kw` (number, required): System size in kW (DC)
- `price` (number, required): Quoted cash price in dollars, before incentives

### `generator_size` (~87 tokens)

Home generator size

The smallest common home standby generator size, with 10% to spare, for the things that must run in an outage: running watts plus the biggest motor's start. Also what generator permits stated as job value, by size, where a city has enough of them. Typical appliance figures; an electrician's load calculation beats them.

Input parameters:

- `loads` (array, required): What must run in an outage
