AI-Native

Your pricing model, accessible to AI

CostPad runs a local MCP server that exposes your simulation to AI assistants. Claude, Cursor, or any MCP client can read your margins, run scenarios, and export reports — without leaving their flow.

8 tools. Real-time sync. Zero config.

MCP Ecosystem

Your SaaS tools talk to each other.
CostPad listens.

AI agents pull real data from Stripe, Supabase, and Resend — then push it into CostPad to model actual costs. CostPad's MCP serves the results back to Claude and Cursor for analysis.
