AI agents call find_dependencies to retrieve information from CodeGraphMCPServer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs static analysis to discover and return dependency information about code entities. It has no side effects—it does not create, modify, delete, or execute code. It is purely informational, analogous to other Read-category tools on this server like 'find_callers', 'find_callees', and 'global_search'.
From the tool's definition Tool name 'find_dependencies' and description 'Find dependencies of a code entity' indicate a query/search operation that retrieves information about code structure without modifying or executing anything.
Documented attack patterns abuse exactly the kind of access find_dependencies gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and CodeGraphMCPServer, and nothing reaches the server without passing your rules. This is the rule we recommend for find_dependencies:
{
"version": "1",
"default": "deny",
"tools": {
"find_dependencies": {}
}
}find_dependencies is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Find dependencies of a code entity. It is categorised as a Read tool in the CodeGraphMCPServer MCP Server, which means it retrieves data without modifying state.
Register the CodeGraphMCPServer MCP server in PolicyLayer and add a rule for find_dependencies: 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 CodeGraphMCPServer. Nothing to install.
find_dependencies 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_dependencies 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_dependencies. 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_dependencies is provided by the CodeGraphMCPServer MCP server (nahisaho/codegraphmcpserver). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from CodeGraphMCPServer, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
