Overview

AI-generated overview

Look up US contractors ranked by city permit activity, permit costs and timelines, plus solar and generator sizing.

What you can do
This remote MCP server exposes contractor data for the United States, organized around city-level building permits. According to its registry description, it ranks contractors by city permits, permit costs and timelines, and also covers solar and generator sizing. No individual tools are listed in the manifest, so the exact operations available are not documented here.
When to use it
Worth adding when an assistant needs US contractor or building-permit context, for example comparing contractors in a city, estimating permit cost and timeline, or sizing solar and generator systems. Less useful for work outside the United States or unrelated to permits and contractors.
Requirements
A remote streamable HTTP endpoint at contractors.fyi; nothing to install locally. The manifest declares no authentication, no environment variables and no headers, and no packages.
Before you install
The manifest declares no authentication and no credentials, so no secrets are requested. The description does not state whether the server only reads data or also writes, sends or changes anything, and it does not say where the underlying permit data comes from; verify that before relying on the results.

Installation

In SourceWeft

  1. Open contractors.fyi in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/fyi.contractors%2Fcontractors/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

list_coverage

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.

Takes no parameters.

find_contractors

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.

Parameterscityrequiredlimitkind_of_workrequired

project_cost

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.

Parameterszipcityrequiredkind_of_workrequired

permit_timeline

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.

Parameterscityrequiredkind_of_workrequired

search_contractor_records

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.

Parametersnamerequired

solar_estimate

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.

Parameterscityrequireduseshome_sizemonthly_kwhmonthly_billelectric_carsmiles_per_carprice_per_kwh

check_solar_quote

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.

Parameterskwrequiredcityrequiredpricerequired

generator_size

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.
