Search for functions by name pattern
AI agents call search_functions 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 data (functions matching a name pattern) from a static codebase analysis without creating, modifying, executing, or deleting anything. It is a non-destructive informational lookup, consistent with the Read category.
From the tool's definition Tool description states 'Search for functions by name pattern' and server provides 'static code analysis' with 'tools for analyzing modules, functions, types, classes, imports'.
Attacks that exploit this kind of access
Search for functions by name pattern. 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 search_functions: 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.
search_functions 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 search_functions 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 search_functions. 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.
search_functions 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.
