WHAT IT DOES

What ultrabrain_think does on Ultrabrain

AI agents invoke ultrabrain_think to trigger actions in Ultrabrain. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why ultrabrain_think needs a policy

The tool acts as an execution gate that runs a multi-step reasoning process (branching, merging, validation, metrics). It doesn't simply read static data nor write persistent records in a traditional sense; it executes a reasoning workflow with side effects like state changes tracked by sibling tools (history, metrics, status). No financial or destructive operations are indicated.

From the tool's definition 'reasoning gate', 'branching, revisions, quality metrics, bias checks, confidence, and meta checkpoints' — triggers a structured reasoning/execution pipeline

Verdict

ultrabrain_think Rate-limited

ultrabrain_think stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Ultrabrain, so you can run agents against it safely.

FAQ

Questions about ultrabrain_think

What does the ultrabrain_think tool do? +

Canonical LCV reasoning gate for code work, branching, revisions, quality metrics, bias checks, confidence, and meta checkpoints. It is categorised as a Execute tool in the Ultrabrain MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on ultrabrain_think? +

Register the Ultrabrain MCP server in PolicyLayer and add a rule for ultrabrain_think: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Ultrabrain. Nothing to install.

What risk level is ultrabrain_think? +

ultrabrain_think is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit ultrabrain_think? +

Yes. Add a rate_limit block to the ultrabrain_think rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block ultrabrain_think completely? +

Set action: deny in the PolicyLayer policy for ultrabrain_think. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides ultrabrain_think? +

ultrabrain_think is provided by the Ultrabrain MCP server (lcv-ideas-software/ultrabrain-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
