AI agents call pattern_stats to retrieve information from Musubix without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns statistics from an internal learning system without side effects. It is a read-only operation that retrieves information about patterns, fitting the Read category definition of 'retrieves or queries data; no side effects.' The low severity reflects minimal security risk from unauthorized access to statistical information about a learning system.
From the tool's definition Tool name 'pattern_stats' and description 'Get statistics about the pattern learning system' indicate a retrieval operation with no modification, deletion, or execution of external operations.
Attacks that exploit this kind of access
Get statistics about the pattern learning system. It is categorised as a Read tool in the Musubix MCP Server, which means it retrieves data without modifying state.
Register the Musubix MCP server in PolicyLayer and add a rule for pattern_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 Musubix. Nothing to install.
pattern_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 pattern_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 pattern_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.
pattern_stats is provided by the Musubix MCP server (@nahisaho/musubix-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
