Simulates 52 weeks of cash flow for a small services business (excavation, plumbing, HVAC, landscaping, roofing) 10,000 times to show the odds of running short, when it's most likely to happen, and which operational changes (pricing, payment terms, crew size, overhead) reduce that risk most.

Example request: "Show me the chance my plumbing business runs out of cash in the next year and which single change would help most."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Dry Run to help me. It is a free service with an MCP server at https://mcp.modernmustardseed.com/dry-run. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- simulate_cash_year: Simulate the next 52 weeks of a small services business 10,000 times (Monte Carlo) and report the chance it runs short of money, the week that is most likely to happen, reachable money (bank balance plus unused credit) week by week at the 10th, 50th and 90th percentile, the drive
- rank_levers: Test nine single changes a small business owner can make and rank them by how much each lowers the chance of running short of money in the next 52 weeks, with the change in year-end money as a tiebreak. The levers: take a third up front, take 15 days off payment terms, raise pric
- list_presets: List the six built-in business presets (excavation and septic, plumbing and drain, heating and cooling, landscaping and snow, roofing, and a general small services business) with every default input in the exact field names a simulation accepts, and the revenue, costs and profit
