Overview

AI-generated overview

Lets an assistant quote UK trades jobs with a labour and call-out fee breakdown plus a tappable JustFix booking link.

What you can do
Exposes three tools from JustFix's public estimator server: list_services returns the 13 service categories with hourly rates, call_out_fee returns the flat booking fee, and service-estimate-card generates a full cost estimate with a unique booking URL. Estimates are labour-only, UK-only, and each is tagged with a tracking identifier for attribution. The user finishes the booking, including date, postcode and payment, on the JustFix website.
When to use it
Useful when a UK customer asks an assistant what a trades job might cost, which services are offered, or what the call-out fee is, and you want a price breakdown and a link to book in one turn. Not suitable for live availability, materials pricing, payment, or jobs outside the UK.
Requirements
A remote streamable-HTTP MCP server at the JustFix estimator endpoint; no authentication, API keys, environment variables or headers are declared. The README also describes placing a skill file where the client's skill discovery finds it, but the MCP tools themselves need only network access.
Before you install
The server is third-party and hosted by JustFix; the skill repository is community-maintained and JustFix states it is responsible only for the underlying server. Estimates are labour-only and exclude materials, availability and payment, which happen on the JustFix booking page. Each estimate carries a tracking identifier, and forks must pass the booking URL through unchanged for attribution.

Installation

In SourceWeft

  1. Open JustFix Estimator 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/io.github.Just-Fix%2Fjustfix-skill/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

Other MCP clients

Add this to your client's mcpServers config.

JustFix Skill 🛠️

Quote UK trades jobs from any AI agent. Get a price breakdown and a tappable booking link in a single turn.

[License: MIT] [Skill format: AgentSkills] [MCP]

👉 How to install JustFix on your AI agent → — Claude Desktop, Cursor, Claude Code, Codex CLI, Gemini CLI, OpenClaw, Hermes, or any MCP-aware client.

See it in action

On OpenClaw + Telegram

Ask Squid (or any OpenClaw agent) for a quote in plain English. The skill maps the request to the right JustFix service code, calls the MCP, and replies with a clean quote card and a tappable booking URL.

In ChatGPT (via the JustFix app)

The same underlying MCP server powers JustFix's official ChatGPT app. The skill in this repo gives you the equivalent experience in any other agent, with a tappable booking link instead of the ChatGPT rich card.

In Claude Code (and Cursor, Codex CLI, Gemini CLI)

The same skill loads natively in Claude Code. Ask in plain English, the skill resolves the service, calls the MCP, and returns the same quote card plus a tappable booking link.

What is this?

A portable AI skill that plugs into JustFix's public MCP server and lets your AI agent quote real trades jobs in real time. Built for OpenClaw, Hermes, Claude Code, Cursor, Codex CLI, Gemini CLI, and any other harness that supports AgentSkills or the Model Context Protocol.

One conversation, one quote, one tap to book.

You: How much would it cost to get someone to fix a broken kitchen tap?
Agent: 🔧 Plumbing Estimate       Scope: Diagnose and repair dripping kitchen tap.       Estimated duration: 1 hour
       Labour (1 hr × £90/hr): £90.00       Call-out fee:           £50.00       Total estimate:        £140.00
       📅 Tap to book this job → my.justfix.app/booking/...

What it does

The skill exposes three MCP tools from JustFix's estimator server to your AI agent:

ToolWhat it does
list_servicesLists JustFix's 13 service categories with hourly rates
call_out_feeReturns the flat booking call-out fee
service-estimate-cardGenerates a full cost estimate plus a unique booking URL

When the user is ready to confirm, the URL pops them to my.justfix.app where they finish the booking (date, postcode, payment).

Supported services

Electrical · Plumbing · Locksmith · Glazing · Carpentry · Handyperson · Heating + Gas · Gas Appliances · Roofing · Drains · White Goods · Boiler Service · Something Else (catch-all)

UK only. Hourly rates from £55 (white goods) to £90 (most trades). £50 flat call-out fee per booking.

If your harness isn't listed but supports MCP, the pattern is:

  1. Register https://estimator-mcp.justfix.app/mcp as a streamable-HTTP MCP server.
  2. Put SKILL.md somewhere the harness's skill discovery picks up (or paste its contents into your agent instructions).
  3. Done. No auth, no config, no API keys.

The MCP server is hosted on Vercel by JustFix and is open – no API key required. Each estimate is tagged with a unique chatgpt_booking_link_id for attribution.

What this skill CAN'T do

Honest about the boundaries:

  • ❌ Complete the booking itself (the user finishes on the JustFix website)
  • ❌ Check live engineer availability (handled at booking time)
  • ❌ Take payment (handled on the booking page)
  • ❌ Quote outside the UK
  • ❌ Quote materials or parts (labour-only estimate)

These are functions of the underlying JustFix product, not the skill. As JustFix expands the MCP, the skill will too.

Branding and attribution

This is an official integration with JustFix's public MCP server, but the skill repo itself is community-maintained. JustFix takes no responsibility for the skill's behaviour – only for the underlying MCP server.

If you fork, modify, or embed this skill, you must:

  • Keep the MIT license intact
  • Not misrepresent the JustFix brand
  • Pass through the booking URL unchanged (for attribution tracking)

Roadmap

When JustFix expands the MCP server, the skill will follow:

  • Engineer availability lookup
  • Quote-to-booking-confirmation in one turn
  • Multi-job bundle pricing
  • Recurring service plans (e.g. annual boiler service auto-rebook)
  • Photo upload for diagnostic estimates

Track progress in GitHub Issues.

Contributing

Pull requests welcome. Please:

  1. Read SKILL.md and understand the format
  2. Run the install/* guides in your own harness to test changes
  3. Open an issue first for anything bigger than a typo fix
