CalcFleet
Deterministic, verifiable calculations for software and AI
CalcFleet is a deterministic calculation platform for people, software, and AI agents. It provides 121 tested, source-cited calculators through the web, JSON APIs, and MCP tools, so critical calculations are performed by versioned formulas rather than improvised by a language model.
CalcFleet is also the first reference implementation of VCC, an experimental open protocol for verifiable calculation receipts. A VCC records the formula version, normalized inputs, outputs, datasets, rounding rules, issuer, timestamp, and cryptographic evidence, making financial calculations easier to inspect, reproduce, and verify across software and AI workflows.
