AI agents call md_navigate 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.
The tool only reads and returns metadata about file link relationships (paths, headings, link text, line numbers). It has no side effects, does not modify any data, and is purely a read/query operation over the markdown knowledge graph.
From the tool's definition 'Document link relationship explorer. Shows which MD files a given file links to (outbound) or which files link to it (inbound). Returns target file paths, file topics (H1), and link text with source line numbers.'

Document link relationship explorer. Shows which MD files a given file links to (outbound) or which files link to it (inbound). Returns target file paths, file topics (H1), and link text with source line numbers. For keyword search, use md_search. To read linked files, use your Read tool. Use depth parameter to expand traversal levels beyond direct links. 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_navigate: 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_navigate 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_navigate 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_navigate. 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_navigate 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.
