Run NetworkX structural analysis to detect knowledge gaps (isolated nodes, disconnected clusters, missing bridges)
AI agents call detect_gaps to retrieve information from Faulkner DB without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only analytical tool that queries and analyzes the knowledge graph structure. NetworkX structural analysis is a query operation that computes properties of the graph but does not create, modify, delete, or execute external code. The tool retrieves insights from existing data with no side effects or state changes. No temporal data is recorded and no external operations are triggered.
From the tool's definition Tool performs analysis using NetworkX to 'detect knowledge gaps' and identify 'isolated nodes, disconnected clusters, missing bridges' — purely analytical operations that examine existing graph structure without modifying, creating, or deleting data.
Attacks that exploit this kind of access
Run NetworkX structural analysis to detect knowledge gaps (isolated nodes, disconnected clusters, missing bridges). It is categorised as a Read tool in the Faulkner DB MCP Server, which means it retrieves data without modifying state.
Register the Faulkner DB MCP server in PolicyLayer and add a rule for detect_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 Faulkner DB. Nothing to install.
detect_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 detect_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 detect_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.
detect_gaps is provided by the Faulkner DB MCP server (platano78/faulkner-db). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
