AI agents call find_broken_links to retrieve information from Obsidian Mcp Pro without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
find_broken_links performs a read-only scan of the vault to identify and report broken wikilinks. It retrieves information about link resolution status and returns findings in a report format. The tool has no side effects: it does not create, modify, delete, or execute any operations.
From the tool's definition Tool description: 'Scan notes for wikilinks', 'Returns a per-source report', 'detection/reporting of broken links' — purely queries and reports existing vault state without modifying data.
Documented attack patterns abuse exactly the kind of access find_broken_links gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Obsidian Mcp Pro, and nothing reaches the server without passing your rules. This is the rule we recommend for find_broken_links:
{
"version": "1",
"default": "deny",
"tools": {
"find_broken_links": {}
}
}find_broken_links is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Scan notes for wikilinks ([[target]]) whose target does not resolve to any existing note in the vault. Returns a per-source report grouping each note with its broken link text and line numbers, plus a total count. Use after renaming, moving, or deleting notes to catch dangling references. Resolution uses the whole vault even when scanning a single folder, so only truly unresolvable links are reported. It is categorised as a Read tool in the Obsidian Mcp Pro MCP Server, which means it retrieves data without modifying state.
Register the Obsidian Mcp Pro MCP server in PolicyLayer and add a rule for find_broken_links: 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 Obsidian Mcp Pro. Nothing to install.
find_broken_links 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 find_broken_links 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 find_broken_links. 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.
find_broken_links is provided by the Obsidian Mcp Pro MCP server (rps321321/obsidian-mcp-pro). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Obsidian Mcp Pro, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
