Thousands of MCP servers hand your agent data. Almost none hand it decisions. AI Rule Engine turns your business logic into governed, deterministic MCP tools - with per-agent permissions, explainable runs, and human approval gates an agent can carry but never bypass.
Why the expression language has no now() or random(), why re-fires key off real value changes, why AI results are remembered for unchanged inputs, and why an inference cascade still meters as one run. Determinism is what makes the rest trustworthy.
