Why obsidian-mcp-search-filenames needs a policy

Searching for filenames is a read-only operation that retrieves information without side effects. It has minimal blast radius—an AI agent misusing this tool could only discover filenames within the vault, not modify or delete content. Lack of description slightly lowers confidence, but the function is sufficiently clear from the name and server context.

From the tool's definition Tool name 'obsidian-mcp-search-filenames' indicates filename search functionality. Description is empty, but naming pattern and sibling tools (list-files, search-contents, read-file) confirm this is a query/search operation without data modification.

Documented attack patterns abuse exactly the kind of access obsidian-mcp-search-filenames gives an agent:

POLICY

How to control obsidian-mcp-search-filenames

PolicyLayer is an MCP gateway — it sits between your AI agents and Vault MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for obsidian-mcp-search-filenames:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "obsidian-mcp-search-filenames": {}
  }
}

obsidian-mcp-search-filenames 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 Vault MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
