Get all nested type definitions for specified types
AI agents call get_nested_types to retrieve information from FDEP MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries type definition information from a codebase without creating, modifying, deleting, or executing any operations. It has no side effects on the analyzed code. Severity is low because misuse would only expose static analysis information about code structure, not enable execution or data destruction.
From the tool's definition Tool name 'get_nested_types' and description 'Get all nested type definitions for specified types' indicate a retrieval operation. The verb 'Get' and the absence of modification language confirm this is a query-only action.
Attacks that exploit this kind of access
Get all nested type definitions for specified types. It is categorised as a Read tool in the FDEP MCP Server MCP Server, which means it retrieves data without modifying state.
Register the FDEP MCP Server MCP server in PolicyLayer and add a rule for get_nested_types: 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 FDEP MCP Server. Nothing to install.
get_nested_types 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_nested_types 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_nested_types. 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_nested_types is provided by the FDEP MCP Server MCP server (juspay/fdep-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
