Search for code objects (classes, functions, methods) in the indexed codebase. Fast direct lookup without RAG. Returns file locations and metadata.
AI agents call search_code_index to retrieve information from RAG Document Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves information from an indexed codebase without modifying, executing, or deleting any data. It is a read-only search operation analogous to grep or IDE symbol lookup. The severity is low because it only exposes already-indexed codebase metadata; no code execution or data modification occurs.
From the tool's definition Tool description states it performs a 'search for code objects' and 'fast direct lookup' that 'returns file locations and metadata.' These are query operations with no side effects.
Attacks that exploit this kind of access
Search for code objects (classes, functions, methods) in the indexed codebase. Fast direct lookup without RAG. Returns file locations and metadata. It is categorised as a Read tool in the RAG Document Server MCP Server, which means it retrieves data without modifying state.
Register the RAG Document Server MCP server in PolicyLayer and add a rule for search_code_index: 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 RAG Document Server. Nothing to install.
search_code_index 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_code_index 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_code_index. 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_code_index is provided by the RAG Document Server MCP server (jaimeferj/mcp-rag-docs). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
