Brain health check and statistics. Reports brain_enabled, counts by type/status/agent, consolidation timestamps.
AI agents call atelier_stats to retrieve information from Mybrain without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and reports aggregate statistics and status information from the knowledge base. It performs no mutations, deletions, or external operations. The blast radius of misuse is minimal—an agent could at worst spam statistics queries, consuming resources, but cannot alter data, execute commands, or cause irreversible harm. Classification as Read is appropriate.
From the tool's definition Tool description indicates it 'Reports brain_enabled, counts by type/status/agent, consolidation timestamps' — purely informational queries about brain statistics and health status with no modifications, deletions, or side effects.
Documented attack patterns abuse exactly the kind of access atelier_stats gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mybrain, and nothing reaches the server without passing your rules. This is the rule we recommend for atelier_stats:
{
"version": "1",
"default": "deny",
"tools": {
"atelier_stats": {}
}
}atelier_stats is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Brain health check and statistics. Reports brain_enabled, counts by type/status/agent, consolidation timestamps. It is categorised as a Read tool in the Mybrain MCP Server, which means it retrieves data without modifying state.
Register the Mybrain MCP server in PolicyLayer and add a rule for atelier_stats: 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 Mybrain. Nothing to install.
atelier_stats is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the atelier_stats 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 atelier_stats. 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.
atelier_stats is provided by the Mybrain MCP server (robertsfeir/mybrain). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mybrain, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
