THE CONNECTION FLOW
Three steps.
Then get back to work.
Signing in and granting an agent access are separate steps. Each connection can be revoked from your workspace.
Open your workspace
A private, expiring invite opens your account. Your allowance belongs to you and is shared across your agents.
Connect your agent
Add the engine URL in an agent that supports remote MCP. Review the connection and approve the services it may use.
Choose a recipe
Ask your agent to use System One to shortlist context, select a tool or check a claim. Inspect the decision and its usage.
FREE PREVIEW ALLOWANCE
10,000 evaluations / month
Enough room to compare several real workflows.
- Shared across every connection to your account
- 64 MiB of decision input per month
- No provider key or credit card required
- No automatic upgrade or paid overage
One model attempt is one evaluation; a tree or log batch may use several. Failed attempts count, while cached and deterministic results use no evaluation. Request size and rate limits also apply.

Fast decisions with something to show for them.
The product is the decision library, your controls and the evidence of what worked. A hosted connection should make those tools easier to use. It does not make an agent automatically faster or more accurate: compare complete tasks and keep the recipes that help.
Prefer to run it yourself?
The local preview remains available with npx sysone. Use your own Vercel AI Gateway key, keep your engine on your machine and pay your provider directly.
Which agents work?
The engine uses remote HTTP MCP and explicit authorization. Individual agents differ in their remote connection and authentication support. We have verified the hosted invitation flow and remote MCP with the protocol SDK. Native ChatGPT, Claude Code and Cursor cloud setup reviews are still pending.
