## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

  "method": "tools/call",
  "params": {
    "name": "zotero_list_libraries",
    "arguments": {}
  }
}
```

## Why zotero_list_libraries is rated Low

The tool lists available Zotero libraries, which is a query operation that retrieves metadata about the user's library structure with no side effects or modifications. No data is created, modified, deleted, or executed. The low severity reflects minimal blast radius—even if misused, it only exposes the existence and names of libraries the user has access to.

From the tool's own definition: "Tool name 'zotero_list_libraries' indicates a listing/retrieval operation. Description is empty, but the naming pattern and sibling tools (search, fetch) on this server are all Read operations."

## Use case

AI agents call zotero_list_libraries 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",
  "default": "deny",
  "tools": {
    "zotero_list_libraries": {}
  }
}
```
