What is JustFix Estimator?
The JustFix Estimator is a powerful integration designed to equip AI agents with real-time quoting capabilities for UK home services. By communicating with the public JustFix Estimator MCP server, this skill allows agents to instantly estimate costs across 13 service categories, including plumbing, electrical work, and locksmithing. It bridges the gap between chat interfaces and real-world execution, enabling a seamless transition from query to actual transaction.
Integrating this tool with Openclaw Skills empowers developers to build highly interactive, transactional virtual assistants. The agent calculates a comprehensive pricing breakdown (including hourly labor rates and flat call-out fees) and provides a unique, attributed booking link that populates directly in the user's browser, simplifying service procurement entirely within the conversational flow.
JustFix Estimator Use Cases
- Providing immediate cost estimates when a user asks "how much to fix a leaking tap" or similar trade job queries.
- Prompting and assisting users with booking certified UK trade services such as electricians, locksmiths, and roofers.
- Helping users understand the breakdown of call-out charges and flat hourly rates before committing to service.
- Redirecting users seamlessly from an AI agent to a pre-filled web checkout to complete bookings securely.
How JustFix Estimator Works
- The agent detects user intent regarding UK trades work (e.g., pricing, bookings, or emergency service requests).
- The agent uses the
list_servicestool if the trade type is ambiguous, or selects the specific service code matching the user's request. - The agent queries
call_out_feeto retrieve current fixed booking fees and calculates labor using standard default hours or user-defined scopes. - The agent calls
service-estimate-cardwith parameters like service_code and booking_description. - The JustFix MCP server returns a detailed cost breakdown and a unique attributed booking URL.
- The agent renders a clean, human-readable card containing the breakdown and a call-to-action button or link.
JustFix Estimator Setup
