List all documentation sources currently stored in the system. Returns a comprehensive list of all indexed documentation including source URLs, titles, and last update times. Use this to understand what documentation is available for searching or to verify if specific sources have been indexed.
AI agents call list_sources 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 is a straightforward read operation that queries and retrieves metadata about indexed documentation sources without any side effects, modifications, or external execution. It fits squarely into the Read category as it only provides visibility into existing system state.
From the tool's definition Tool 'list_sources' returns a list of indexed documentation sources including URLs, titles, and update times.

List all documentation sources currently stored in the system. Returns a comprehensive list of all indexed documentation including source URLs, titles, and last update times. Use this to understand what documentation is available for searching or to verify if specific sources have been indexed. 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_sources: 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_sources 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_sources 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_sources. 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_sources is provided by the RAG Documentation MCP Server MCP server (jumasheff/mcp-ragdoc-fork). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
