About 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.
Pydantic AI validates every SignOnSite tool response against typed schemas, catching data inconsistencies at build time. Connect 12 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.
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.
The SignOnSite MCP Server exposes 12 tools through the Vinkius. Connect it to Pydantic AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
