Why obsidian_fuzzy_search needs a policy

This tool retrieves and searches data from Obsidian notes without creating, modifying, deleting, or executing any operations. It is a pure read operation that matches the 'Read' category (retrieves or queries data; no side effects). Low severity because search operations have minimal blast radius even if misused by an agent.

From the tool's definition Tool description states 'fuzzy search for notes' and 'finding notes' - these are query/search operations with no modification capabilities. The server description emphasizes 'search, read, and analyze' as read-only operations.

How to control obsidian_fuzzy_search

PolicyLayer is an MCP gateway — it sits between your AI agents and Obsidian MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for obsidian_fuzzy_search:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "obsidian_fuzzy_search": {}
  }
}

obsidian_fuzzy_search is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Obsidian MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
