List all repositories that have been indexed in the code index.
AI agents call list_indexed_repos 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.
This tool performs a query/list operation to retrieve metadata about indexed repositories. It has no side effects, does not modify or delete data, does not execute code, and does not involve financial transactions. The action is purely informational retrieval, placing it squarely in the Read category with low severity since exposure only allows an AI agent to discover which repositories exist in the index.
From the tool's definition Tool name 'list_indexed_repos' and description 'List all repositories that have been indexed in the code index' indicate a read-only operation that retrieves and enumerates indexed repositories without modification, deletion, or execution.
Attacks that exploit this kind of access
List all repositories that have been indexed in the code index. 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 list_indexed_repos: 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.
list_indexed_repos 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 list_indexed_repos 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 list_indexed_repos. 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.
list_indexed_repos 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.
