List all local repositories currently indexed in the system. Returns details about each repository including path, include/exclude patterns, and watch mode status.
AI agents call list_repositories to retrieve information from RAG Documentation MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and displays information about indexed repositories without modifying, creating, or deleting any data. It has no side effects and poses minimal security risk—it is a simple informational query operation typical of Read category tools.
From the tool's definition Tool name 'list_repositories' and description explicitly states it 'List all local repositories' and 'Returns details about each repository'. Uses read-only verbs (list, returns) with no modification, deletion, or execution implied.
Documented attack patterns abuse exactly the kind of access list_repositories gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and RAG Documentation MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_repositories:
{
"version": "1",
"default": "deny",
"tools": {
"list_repositories": {}
}
}list_repositories is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all local repositories currently indexed in the system. Returns details about each repository including path, include/exclude patterns, and watch mode status. It is categorised as a Read tool in the RAG Documentation MCP Server MCP Server, which means it retrieves data without modifying state.
Register the RAG Documentation MCP Server MCP server in PolicyLayer and add a rule for list_repositories: 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 Documentation MCP Server. Nothing to install.
list_repositories 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_repositories 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_repositories. 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_repositories is provided by the RAG Documentation MCP Server MCP server (rahulretnan/mcp-ragdocs). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
