Overview

AI-generated overview

A hosted, read-only MCP server that lets an assistant look up single ConstructionOnline contacts, projects, opportunities and schedules by id, email or phone.

What you can do
  • Look up a contact by id, email address or phone number
  • Read a single project by its id
  • Read a single opportunity by its id
  • Read a single schedule by its id
  • Check monthly tool-call usage, request a missing feature, or manage a Pro subscription
When to use it
Useful when you already work in ConstructionOnline and want an assistant to pull up one contact, project, opportunity or schedule while chatting, without opening the app. It is a lookup-only helper, not a way to create or edit records.
Requirements
A remote MCP endpoint added by URL only; no API key or Authorization header goes in the client config. Sign-in happens through the hosted OAuth flow using your ConstructionOnline credentials. A free tier allows 50 tool calls per month; paid plans raise the limit.
Before you install
The server asks for your ConstructionOnline login through its OAuth page, so only sign in on the official endpoint. Paid plans cost money: Pro is $9/month or $90/year and Pro+ is $39/month or $390/year, billed through a Stripe Checkout link, with no refund for the current period on cancellation. The upgrade, cancel and feature-request tools change your subscription or send data to the provider. Lookups return selected operational fields only, with notes, permissions, attachments and payroll…

Installation

In SourceWeft

  1. Open ConstructionOnline 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%2Fconstructiononline/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

ConstructionOnline MCP by usefulapi

Remote MCP endpoint: https://constructiononline.usefulapi.io/mcp

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://constructiononline.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http constructiononline https://constructiononline.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": {    "constructiononline": {      "url": "https://constructiononline.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 ConstructionOnline credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/constructiononline/

Connect with your ConstructionOnline credentials using the hosted authorization flow.
