Find related knowledge nodes via graph traversal
AI agents call find_related 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 tool performs graph traversal to discover relationships between knowledge nodes. Graph traversal and node discovery are read operations that retrieve data without side effects. The operation depends on traversal logic and filters rather than arbitrary code execution, and it cannot modify or delete data.
From the tool's definition Tool name 'find_related' and description 'Find related knowledge nodes via graph traversal' indicates a graph query/traversal operation that retrieves and navigates existing nodes without modification.
Attacks that exploit this kind of access
Find related knowledge nodes via graph traversal. 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 find_related: 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.
find_related 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 find_related 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 find_related. 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.
find_related 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.
