brain_compile
Compile a trained brain into a portable .brain file. The .brain file can be imported into any app on any LLM. Also generates the system prompt version for direct use. Example: brain_compile({ brain_id:

What brain_compile does on 0nmcp
AI agents invoke brain_compile to trigger actions in 0nmcp. 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 brain_compile is rated High
This tool triggers a compilation/generation process that transforms a trained model artifact into a portable file format. It executes a build-like operation with side effects (file creation), placing it in the Execute category. Severity is medium as misuse could generate unauthorized or malicious system prompts, but the blast radius is limited compared to code execution or destructive operations.
From the tool's definition 'Compile a trained brain into a portable .brain file' and 'generates the system prompt version for direct use'
Attacks that exploit this kind of access
The rule that runs brain_compile safely
PolicyLayer is an MCP gateway: it sits between your AI agents and 0nmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For brain_compile, this is the rule to start with:
brain_compile 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.
The button opens the PolicyLayer dashboard: create your workspace, connect 0nmcp, apply this rule, and every brain_compile call is checked against it from then on.
Questions about brain_compile
Compile a trained brain into a portable .brain file. The .brain file can be imported into any app on any LLM. Also generates the system prompt version for direct use. Example: brain_compile({ brain_id:. It is categorised as a Execute tool in the 0nmcp MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the 0n MCP server in PolicyLayer and add a rule for brain_compile: 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 0nmcp. Nothing to install.
brain_compile is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the brain_compile 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.
Set action: deny in the PolicyLayer policy for brain_compile. 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.
brain_compile is provided by the 0n MCP server (0nmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
