AI agents call gap to retrieve information from Kb without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name 'gap' and its position among sibling tools (read, search, knowledge, adr) suggests it retrieves gap information for reflection or analysis rather than modifying or executing actions. However, with no description provided, confidence is moderate. If it were destructive or execute-class, the empty description is a concern for safe deployment.
From the tool's definition Tool name 'gap' with empty description; inferred from context that it likely queries or retrieves gap information from the knowledge base (consistent with sibling tools like 'read', 'search', 'knowledge' which are read operations).
Attacks that exploit this kind of access
gap. It is categorised as a Read tool in the Kb MCP Server, which means it retrieves data without modifying state.
Register the Kb MCP server in PolicyLayer and add a rule for gap: 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 Kb. Nothing to install.
gap 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 gap 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 gap. 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.
gap is provided by the Kb MCP server (okash1n/kb). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
