## Why zotero_library_coverage is rated Low

This tool appears to retrieve or report metrics about library coverage (e.g., what percentage of items have attachments, how many entries exist, citation coverage, etc.). No side effects are indicated. The empty description and naming convention align with Read category operations.

From the tool's own definition: "Tool name 'zotero_library_coverage' suggests a read-only query operation. Server context indicates tools are designed to 'search your library, access content' with no mention of modifications."

## Use case

AI agents call zotero_library_coverage to retrieve information from Zotero MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Zotero MCP:

```json
{
  "version": "1",
