AI agents call list_gaps to retrieve information from Control-Inventory-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 returns information about control implementation status. It performs no side effects, creates no modifications, executes no code, and causes no irreversible changes. It is a straightforward read operation on an inventory database, similar in nature to the sibling 'search_controls' and 'get_control' tools.
From the tool's definition Tool name 'list_gaps' and description indicating it 'List[s] every control that is not fully implemented' — a pure retrieval/reporting operation with no data modification, deletion, or execution capability.

List every control that is not fully implemented (status 'partial' or. It is categorised as a Read tool in the Control-Inventory-MCP-Server MCP Server, which means it retrieves data without modifying state.
Register the Control-Inventory-MCP-Server MCP server in PolicyLayer and add a rule for list_gaps: 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 Control-Inventory-MCP-Server. Nothing to install.
list_gaps 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 list_gaps 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 list_gaps. 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.
list_gaps is provided by the Control-Inventory-MCP-Server MCP server (miguelangelhorta/control-inventory-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
