Group functions by similarity to identify common patterns
AI agents call group_similar_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 performs pattern recognition and grouping of functions based on similarity metrics. It reads and queries function metadata to produce analytical output, but does not modify, execute, delete, or create any code or data. The operation has no side effects on the codebase being analyzed.
From the tool's definition Tool name 'group_similar_functions' and description 'Group functions by similarity to identify common patterns' indicate a query/analysis operation that retrieves and categorizes existing code metadata.
Attacks that exploit this kind of access
Group functions by similarity to identify common patterns. 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 group_similar_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.
group_similar_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 group_similar_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 group_similar_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.
group_similar_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.
