Get memory system health status - indexes, database size, configuration.
AI agents call memory_health to retrieve information from Memory-MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only status checks on the memory system infrastructure. It queries and returns diagnostic information but produces no side effects, data modifications, code execution, or destructive actions. It is analogous to a system monitoring or health check endpoint.
From the tool's definition Tool name 'memory_health' and description 'Get memory system health status' indicate a retrieval/query operation that returns system metrics (indexes, database size, configuration) without modifying or executing anything.
Attacks that exploit this kind of access
Get memory system health status - indexes, database size, configuration. It is categorised as a Read tool in the Memory-MCP MCP Server, which means it retrieves data without modifying state.
Register the Memory- MCP server in PolicyLayer and add a rule for memory_health: 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 Memory-MCP. Nothing to install.
memory_health 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 memory_health 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 memory_health. 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.
memory_health is provided by the Memory- MCP server (wb200/memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
