[See setup guidance ↓](#setup)[Original source ↗](https://github.com/54yyyu/zotero-mcp) SOURCE REVIEW Reviewed 2026-10-14 Evidence 5 linked sources Publisher 54yyyu Licence [MIT ↗](https://github.com/54yyyu/zotero-mcp/blob/075cf2c59842c0f195d25aeef87d3475254ef70b/LICENSE) Revision 075cf2c59842 [Read what was—and wasn’t—checked ↓](#review) “Search your library, read and annotate papers, add and organize items, and find research by meaning.” [54yyyu · upstream description ↗](https://github.com/54yyyu/zotero-mcp/blob/075cf2c59842c0f195d25aeef87d3475254ef70b/README.md) Our analysis follows below. 01 / THE REASONING ## Why this made the selection. - The README install line is `uv tool install zotero-mcp-server`. - The repository description limits the data to the user’s Zotero library, which is a citable personal corpus rather than a web scrape. - The pinned README connects a Zotero library to an MCP client, reading the local database or using the web API. - Local writes need a one-time authorization on Zotero 10, or an API key on older versions. ### A good fit for - Inspect exact item/attachment metadata and bounded PDF pages before synthesizing a literature claim. - Find duplicate bibliography entries and review a dry-run merge before any library change. - Searching and reading a Zotero library that is already on this computer - Adding items by DOI or file when local write access has been allowed ### Weigh up before choosing - This is not published by Zotero. Endpoint and library-format changes are the maintainer’s problem. - A summary of a paper is not the paper. - ZOTERO_LOCAL=true selects local reads, not a guaranteed read-only permission boundary. Zotero10+ can authorize local writes, and stored web credentials can provide a hybrid write path. - ZOTERO_LOCAL_WRITE=false forces writes to the web API rather than disabling every write. Revoking the server-stored key is distinct from clearing Zotero own authorization record. - SQLite snapshots can lag recent edits; PDF text extraction is unreliable for some equations/tables, so inspect flagged page images when accuracy matters. - Local mode still needs Zotero's setting that allows other applications on this computer to connect. - Writes on older Zotero go through the web API and need an API key and library id. - The README contrasts the MCP server with a skill because every tool schema is sent on every request. - A pin does not verify transitive dependencies. - This review did not execute the resource. 02 / THE REVIEW RECORD ## What we actually inspected. Source review has boundaries. A clear record is more useful than a “safe” badge. ### Material inspected - README.md - 2026-10-14 reread of retained pinned setup/configuration evidence for the specific operational details added in this batch. - docs/configuration.md - docs/tools.md - LICENSE ### Our findings - Install line offers uv tool install zotero-mcp-server or pip install zotero-mcp-server. - Additional configuration/tools docs distinguish direct SQLite reads, local/web/hybrid write paths, snapshot refresh and optional tool groups. Local/write mode and library identity are now explicit. - Local mode reads the library from zotero.sqlite. Writes go to a running Zotero 10 or through the web API. - Zotero 7 must be set to allow other applications on this computer to communicate with it. Writes on Zotero 10 need zotero-mcp authorize-local; older versions need ZOTERO_API_KEY and ZOTERO_LIBRARY_ID. - Semantic search can call OpenAI, Gemini, or Ollama. The README does not claim the MCP path avoids sending tool schemas; it says every schema is sent on every request. ### Not established by this review - No Zotero library was opened. - No authenticated session, installation, permission bypass or package-to-source parity test was performed. - The server was not started and its tools were not called. - A pin does not verify transitive dependencies. The review applies to the material and revision named here. A newer upstream release can change its behavior. 03 / PUT IT TO WORK ## Connect a server deliberately. [Upstream setup instructions ↗](https://github.com/54yyyu/zotero-mcp/blob/075cf2c59842c0f195d25aeef87d3475254ef70b/README.md) DOCUMENTED COMMAND uv tool install zotero-mcp-server Copy command ↗ Copying does not execute this command. It may retrieve a newer version than the reviewed source. - Install zotero-mcp-server with uv and a supported Python 3.10+ interpreter. - For local use, enable communication with other applications in Zotero settings. - Run zotero-mcp setup for Claude Desktop, or register zotero-mcp with ZOTERO_LOCAL=true in another supported client. - Only if writes are intended, authorize the Zotero 10+ local route or configure a suitably scoped web API key and library ID. ### Before you start - uv or pip - A Zotero library ### Documented configuration example Use the client and authentication context described in the setup guidance. Configuration formats vary between hosts. { "mcpServers": { "zotero": { "command": "zotero-mcp", "env": { "ZOTERO_LOCAL": "true" } } } } Copy configuration ↗ ### Compatibility Local stdio MCP clients · A local or API-accessible Zotero library ### Implementation Python ### Transports stdio · Streamable HTTP · SSE ### Local process, your library - Read the configured Zotero library ### Cost model MIT server.
