Simpro MCP server: connect Simpro to Claude and ChatGPT

Simpro is reached through its API with credentials that can only read your administrator authorises. Junction builds only read requests, applies the API's paging and rate limits, and adds its own limits and sensitivity rules on top.

• “Which jobs are over their quoted cost?”
• “Which invoices are unpaid after 30 days?”
• “Which quotes are still waiting for a customer decision?”

Answers come from your own system, with the source rows and the time the data was last updated.

• Simpro is widely used (markets: Australia, United Kingdom, United States) and readable without writing to it. We build each mapping from the vendor's own reference and check it with a customer who runs the system.
• Integration routes found in our research: REST API, Webhooks.
• When we researched this in October 2026 the vendor offered no MCP server of its own; only unofficial, community-built ones existed.
• Payroll and personal data are denied by default.
