AI agents call suggest_tags to retrieve information from Obsidian Ai Curator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads note content and generates suggestions; it does not create, modify, delete, or execute operations. It has minimal blast radius—worst case, an AI agent receives inappropriate tag suggestions, which are harmless without subsequent write or execute actions. The tool fits the 'Read' category as it retrieves and analyzes data with no side effects.
From the tool's definition Tool description states it 'Suggest tags based on note content' — a retrieval and analysis operation. The name 'suggest_tags' and verb 'suggest' indicate a read-only operation that examines existing note content to propose tags, without modifying data or…
Documented attack patterns abuse exactly the kind of access suggest_tags gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Obsidian Ai Curator, and nothing reaches the server without passing your rules. This is the rule we recommend for suggest_tags:
{
"version": "1",
"default": "deny",
"tools": {
"suggest_tags": {}
}
}suggest_tags is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Suggest tags based on note content. It is categorised as a Read tool in the Obsidian Ai Curator MCP Server, which means it retrieves data without modifying state.
Register the Obsidian Ai Curator MCP server in PolicyLayer and add a rule for suggest_tags: 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 Ai Curator. Nothing to install.
suggest_tags 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 suggest_tags 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 suggest_tags. 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.
suggest_tags is provided by the Obsidian Ai Curator MCP server (nwant/obsidian-ai-curator). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Obsidian Ai Curator, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
