Service Fusion MCP by usefulapi

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:

{
  "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.
