AI agents call md_files to retrieve information from Md Graph 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 metadata about indexed Markdown files (names, topics, link counts, recent changes). It performs no writes, executions, deletions, or financial operations. Misuse potential is minimal — it only exposes file structure information.

FILE TREE OVERVIEW — shows all indexed MD files organized by directory. Returns file names, H1 topics, outbound link counts, and marks files recently added (✚) or modified (✎) within the last 30 minutes. Use at the start of a session to see the full document landscape. For keyword search, use md_search. For link relationships, use md_navigate. For detailed change info, use md_status. It is categorised as a Read tool in the Md Graph MCP Server, which means it retrieves data without modifying state.
Register the Md Graph MCP server in PolicyLayer and add a rule for md_files: 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 Md Graph. Nothing to install.
md_files 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 md_files 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 md_files. 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.
md_files is provided by the Md Graph MCP server (lzmw/md-graph). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
