Overview

AI-generated overview

Hosted MCP server for Service Fusion field-service data: look up customers, jobs, estimates, invoices, schedules and technicians, and create customers, jobs…

What you can do
  • Look up customers and their equipment, including contacts, locations and custom fields
  • Search and read jobs, estimates and invoices with filters and expanded details
  • Read calendar tasks, technician availability, technicians, departments and crews
  • List reference data such as job categories, job statuses, payment types and lead sources
  • Create a customer, a job or an estimate (write tools, each needing confirmation)
  • Check usage, request a feature, upgrade or cancel a paid plan
When to use it
Useful when an assistant should answer questions about a Service Fusion account — scheduled jobs, unpaid invoices, technician availability — or draft new customers, jobs and estimates without opening the app.
Requirements
A remote endpoint only, no local install. Connect with the URL and sign in through OAuth using the Client ID and Client Secret of a Service Fusion API credential; do not add an Authorization header or API key to the client config. A free plan allows 50 tool calls per month; paid plans are billed per user.
Before you install
Three tools create data in Service Fusion: created customers, jobs and estimates are visible to the whole team and cannot be deleted through this API, and repeating a call creates duplicates. Paid plans cost money (Pro $9/month or $90/year, Pro+ $39/month or $390/year) and are charged through a Stripe Checkout link; cancellation runs to the end of the paid period with no refund. Service Fusion credentials are entered on the provider's OAuth login page.

Installation

In SourceWeft

  1. Open Service Fusion MCP by usefulapi 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.usefulapi%2Fservice-fusion/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.

README

Service Fusion MCP by usefulapi

Use Service Fusion from Claude, Cursor, or any MCP client — look up customers and their equipment, jobs, estimates, invoices, calendar tasks, technicians, crews and technician availability, and create a customer, a job or an estimate (each write needs an explicit confirmation). Hosted, no local install: connect with the Client ID and Client Secret of a Service Fusion API credential.

Live endpoint: https://service-fusion.usefulapi.io/mcp · Homepage: https://usefulapi.io/service-fusion

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://service-fusion.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http service-fusion https://service-fusion.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
json
{  "mcpServers": {    "service-fusion": {      "url": "https://service-fusion.usefulapi.io/mcp"    }  }}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Service Fusion credentials.
