Current audit-chain head: hash, depth, last-anchor information. Use to answer
AI agents call get_audit_chain_head to retrieve information from KVMFleet MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves audit-chain state information for monitoring and compliance purposes. It performs no data modification, deletion, or execution of external operations. The read-only server design and query-focused function classify this as a Read operation with low severity, as misuse would only expose existing audit information without enabling unauthorized actions.
From the tool's definition Tool name and description indicate retrieval of audit-chain metadata (hash, depth, last-anchor information). The server is explicitly described as 'Read-only MCP server that allows AI assistants to query and monitor'.

Current audit-chain head: hash, depth, last-anchor information. Use to answer. It is categorised as a Read tool in the KVMFleet MCP Server MCP Server, which means it retrieves data without modifying state.
Register the KVMFleet MCP Server MCP server in PolicyLayer and add a rule for get_audit_chain_head: 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 KVMFleet MCP Server. Nothing to install.
get_audit_chain_head 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_audit_chain_head 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_audit_chain_head. 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_audit_chain_head is provided by the KVMFleet MCP Server MCP server (kvmfleet/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
