get_etcd_disk_wal_fsync
AI agents call get_etcd_disk_wal_fsync to retrieve information from OCP Performance Analyzer MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get_' prefix and placement among sibling tools that all appear to be read-only performance metrics retrieval tools suggests this retrieves etcd write-ahead log (WAL) fsync performance metrics. No modification, execution, deletion, or financial operations are implied. The tool would analyze disk fsync behavior for performance insights, consistent with the server's monitoring purpose.
From the tool's definition Tool name 'get_etcd_disk_wal_fsync' uses 'get_' prefix pattern, consistent with sibling tools like 'get_api_server_stats', 'get_etcd_cluster_status', 'get_etcd_general_info' which retrieve monitoring and status data.
Attacks that exploit this kind of access
get_etcd_disk_wal_fsync. It is categorised as a Read tool in the OCP Performance Analyzer MCP MCP Server, which means it retrieves data without modifying state.
Register the OCP Performance Analyzer MCP server in PolicyLayer and add a rule for get_etcd_disk_wal_fsync: 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 OCP Performance Analyzer MCP. Nothing to install.
get_etcd_disk_wal_fsync 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 get_etcd_disk_wal_fsync 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 get_etcd_disk_wal_fsync. 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.
get_etcd_disk_wal_fsync is provided by the OCP Performance Analyzer MCP server (openshift-eng/ocp-performance-analyzer-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
