AI agents call pulse to retrieve information from Ombre Brain without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and summarizes system state and memory bucket information without modifying, deleting, or executing external operations. It is a read-only diagnostic/status query that reports on the emotional memory system's current state. No side effects or data mutations are indicated.
From the tool's definition Tool name 'pulse' and description indicating it returns '系统状态和所有记忆桶摘要' (system status and summary of all memory buckets), with optional archive inclusion.
Documented attack patterns abuse exactly the kind of access pulse gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ombre Brain, and nothing reaches the server without passing your rules. This is the rule we recommend for pulse:
{
"version": "1",
"default": "deny",
"tools": {
"pulse": {}
}
}pulse is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
系统状态和所有记忆桶摘要。include_archive=True 时包含归档桶。. It is categorised as a Read tool in the Ombre Brain MCP Server, which means it retrieves data without modifying state.
Register the Ombre Brain MCP server in PolicyLayer and add a rule for pulse: 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 Ombre Brain. Nothing to install.
pulse 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 pulse 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 pulse. 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.
pulse is provided by the Ombre Brain MCP server (p0lar1zzz/ombre-brain). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
