What is the SignOnSite MCP Server?

Connect your SignOnSite account to any AI agent and take full control of your construction site safety and attendance orchestration through natural conversation. SignOnSite provides a premier platform for managing worker sign-ons, safety inductions, and site attendance, and this integration allows you to retrieve site metadata, monitor worker enrollments, and track safety briefings directly from your chat interface.

What you can do

  • Worker & Site Orchestration — List all active sites and retrieve detailed worker profile metadata, including enrollment status and contact info programmatically.
  • Attendance Lifecycle Management — Monitor real-time worker sign-ons and sign-offs to ensure your site attendance is always accurate directly from the AI interface.
  • Safety & Permit Control — Access and monitor site permits and safety briefings to ensure your workplace compliance is always synchronized via natural language.
  • Enrolment & Credential Intelligence — Access worker credentials and manage enrolment flows to keep your compliance records up to date.
  • Operational Monitoring — Track site activities and manage company metadata to ensure your safety orchestration is always optimized using simple AI commands.

How it works

1. Subscribe to this server
2. Enter your SignOnSite API Token from your dashboard
3. Start managing your site safety from Claude, Cursor, or any MCP-compatible client

No more manual sign-on sheets or chasing safety certificates. Your AI acts as a dedicated safety officer or site manager.

Who is this for?

  • Site Managers & Foremen — quickly retrieve worker attendance and monitor safety induction statuses without switching apps.
  • Safety Officers — automate the retrieval of site permits and track compliance credentials via natural conversation.
  • Operations Teams — streamline the retrieval of site-user metadata and monitor multi-site activities directly within the chat.

FAQ

Frequently asked questions

01

Can my AI automatically find which workers are currently signed onto a specific construction site?

Yes! Use the query_attendance tool. Provide the Site ID, and your agent will return the list of currently present workers and their sign-on times in seconds.

02

How do I check if a specific worker has completed their safety induction for a site?

Simply ask the agent to run the get_worker or query_credentials action. It will retrieve the enrollment status and safety credentials for that individual.

How do I find my SignOnSite API Token?

Log in to your SignOnSite web dashboard, navigate to the Settings > API section, and you will find your unique Company API Token there.
