Find the shortest call chain from one function to another using recursive CTE graph traversal.
AI agents call find_call_chain 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 performs purely analytical queries against a local SQLite database of Unreal Engine code structure. It has no side effects: it does not execute code, modify data, delete records, or perform financial transactions. The 'find' prefix combined with the descriptive action of 'finding' (rather than 'running', 'executing', or 'deleting') indicates it is a retrieval/query tool.
From the tool's definition The tool 'find_call_chain' queries a graph structure to find the shortest call chain between functions, using 'recursive CTE graph traversal.' This is fundamentally a read operation—it retrieves information about function relationships in an already-indexed…
Attacks that exploit this kind of access
Find the shortest call chain from one function to another using recursive CTE graph traversal. 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 find_call_chain: 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.
find_call_chain 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_call_chain 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_call_chain. 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_call_chain 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.
