Find functions similar to a given function based on signature and code
AI agents call find_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 is a Read operation because it performs a similarity search across functions to retrieve matching results. It has no side effects, does not execute code, does not modify data, and does not trigger external operations. Static code analysis tools that inspect codebases are inherently non-destructive query operations.
From the tool's definition Tool description states 'Find functions similar to a given function' which is a retrieval/query operation.
Attacks that exploit this kind of access
Find functions similar to a given function based on signature and code. 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 find_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.
find_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 find_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 find_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.
find_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.
