zotero-assistant-mcp
A Zotero library management MCP server designed for Cloudflare Workers that enables searching, reading, and writing library items. It allows users to manage metadata, full-text content, and attachments through natural language interactions.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
list_groupsList Zotero groups the user belongs to. Returns group IDs for use with group_id params.
search_itemsSearch the Zotero library by text, tags, type, collection, or date range.
get_collection_itemsList items in a specific collection.
list_collectionsList all collections (folders) in the library.
create_collectionCreate a new collection, optionally nested under a parent.
list_tagsList tags in the library with item counts.
get_library_statsLibrary overview: total items, collections, top tags, and last modified item.
get_itemGet full metadata and children for a single item.
read_attachmentRead attachment content. Accepts parent item key or attachment key — auto-detects type and extracts content.
get_noteRead note content. Pass a note key for one note, or a parent item key for all child notes.
save_itemCreate a new item in the Zotero library with metadata and optional attachment.
attachAttach a file to an existing Zotero item. Supports PDF URLs, webpage snapshots, and base64 file content.
create_noteCreate a note attached to an existing item. Supports HTML content.
update_itemUpdate metadata on an existing item. Pass only fields to change.
trash_itemMove a note or attachment to trash. Only works on notes/attachments for safety.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
When Vitest UI server is listening, arbitrary file can be read and executed
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Wrangler affected by OS Command Injection in `wrangler pages deploy`
Cloudflare Agents is Vulnerable to Reflected Cross-Site Scripting in the AI Playground's OAuth callback handler
Cloudflare Agents SDK has Insecure Direct Object Reference (IDOR) via Header-Based Email Routing
Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
15/15 tools missing one or more hints — list_groups (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_items (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_collection_items (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +12 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
14/15 tool handlers declare input schemas (93%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 2/15 tool handlers wrap calls in try/catch (13%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
Only 3/15 tools referenced in tests (20%)
Write tests that reference each tool by name so every tool has at least one test.
Tests pass
npm test failed — tests do not pass
Make sure npm test runs cleanly. Common cause: missing build step or missing env vars.
Production dependencies are patched
0 critical, 1 high severity in production deps — @modelcontextprotocol/sdk@1.25.2 (high), agents@0.3.6 (medium)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dev dependencies
2 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
