Show embedding and vault statistics for your Obsidian vault
AI agents call stats to retrieve information from Ob Smart Connections without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns statistical information about the vault's embeddings and content. It has no side effects, cannot modify data, execute code, or perform destructive actions. It is a pure read operation that aggregates and displays metadata about the vault state.
From the tool's definition Tool name 'stats' and description 'Show embedding and vault statistics for your Obsidian vault' indicates retrieval and display of aggregate statistics only, with no capability to modify, delete, or execute operations.
Documented attack patterns abuse exactly the kind of access stats gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ob Smart Connections, and nothing reaches the server without passing your rules. This is the rule we recommend for stats:
{
"version": "1",
"default": "deny",
"tools": {
"stats": {}
}
}stats is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Show embedding and vault statistics for your Obsidian vault. It is categorised as a Read tool in the Ob Smart Connections MCP Server, which means it retrieves data without modifying state.
Register the Ob Smart Connections MCP server in PolicyLayer and add a rule for stats: 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 Ob Smart Connections. Nothing to install.
stats 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 stats 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 stats. 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.
stats is provided by the Ob Smart Connections MCP server (yejianye/ob-smart-connections-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Ob Smart Connections, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
