Get the inheritance hierarchy for a class (ancestors, descendants, or both).
AI agents call get_class_hierarchy to retrieve information from Ue Codegraph without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a local SQLite database to retrieve class hierarchy information. It has no side effects, does not execute code, does not modify data, and does not delete or move resources. It is purely informational retrieval from a code analysis index.
From the tool's definition Tool description states 'Get the inheritance hierarchy for a class (ancestors, descendants, or both)' — a pure retrieval operation with no modification, deletion, or execution of code.
Attacks that exploit this kind of access
Get the inheritance hierarchy for a class (ancestors, descendants, or both). It is categorised as a Read tool in the Ue Codegraph MCP Server, which means it retrieves data without modifying state.
Register the Ue Codegraph MCP server in PolicyLayer and add a rule for get_class_hierarchy: 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 Ue Codegraph. Nothing to install.
get_class_hierarchy 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_class_hierarchy 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_class_hierarchy. 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_class_hierarchy is provided by the Ue Codegraph MCP server (yomenstyle/ue-codegraph-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
