- Server: Zotero MCP (`pypi:zotero-mcp-server`) — https://policylayer.com/tools/54yyyu-zotero-mcp.md
- Install: `npx -y pypi:zotero-mcp-server`
- Homepage: https://github.com/54yyyu/zotero-mcp
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "fetch",
    "arguments": {}
  }
}
```

## Why fetch is rated Low

Given the server's primary purpose is to query and access a research library, and the tool name 'fetch' is typically used for retrieval operations, this is classified as Read. The empty description reduces confidence slightly, but the Zotero context and sibling tools (search, various read-only access methods) strongly suggest data retrieval with no side effects.

From the tool's own definition: "Tool named 'fetch' with no description provided. Based on context of Zotero MCP server which supports searching, accessing content, and retrieving library data, 'fetch' most likely retrieves research items or content from the library without modification."

## Use case

AI agents call fetch 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": {
    "fetch": {}
  }
}
```
