Constitutional Gate ships free today — 100 rules, MCP-native, fail-open. Triple-Gate runtime validation (USPTO 64/006,491) in early access. Both built on the same patent-protected validation architecture.

Start free with the Gate today — the freemium entry to the whole stack. Step up to runtime validation, persistent memory, and pre-deploy audit on the same cryptographic spine.
Constitutional hook engine for AI coding agents. Intercepts every agent action and blocks rule violations before they execute — 100 rules, 32 enforced locally with no account, no API key, no telemetry.

Rules written into a README, a system prompt, or a style guide are advisory — the agent reads them, then does whatever its sampler decides. Sunaiva moves enforcement out of the prompt and into the protocol: every product here intercepts an action or an output and applies deterministic, mathematical, cryptographically-bound checks before anything ships.
The Gate enforces agent actions. The Triple-Gate MCP enforces model outputs with conjunctive AND-logic. Memory and Ship Confidence extend the same spine to recall and release.
Rules evaluate locally in under a millisecond. Same input, same verdict, every time — no model in the hot path for the free tier.
If the gate hits an internal error during evaluation, it degrades to pass-through. Your agent never deadlocks on our code.
Speaks the Model Context Protocol directly. Tool-callable by the generating model — validation invoked during generation, not bolted on after.
Triple-Gate and Ship Confidence emit signed verdicts: gate signatures, output hash and timestamp bound into a composite proof.
The Constitutional Gate is free for personal and evaluation use under BUSL-1.1. Paid tiers add server-side rules, BYOK, multi-seat and custom rule authoring — $49 / $299 per seat.
