Zotero MCP Server: Programmatic Access to Your Zotero Library

Overview: What is Zotero MCP Server?

Zotero MCP (Model Context Protocol) Server provides a standardized interface for AI applications, such as Anthropic Claude App, Goose, and potentially Cline from VSCode. By leveraging the Model Context Protocol, this server allows seamless interaction with your local Zotero library, enabling advanced features like paper searching, annotation management, and summarization directly within your AI workflow.

🔧 Core Features & MCP Capabilities

The Zotero MCP Server offers a robust set of capabilities that enhance both local and remote access to Zotero's extensive bibliographic data. This includes:

Search Functionality: Efficiently search papers by tags, ensuring quick retrieval of relevant information.
Paper Details & Notes Management: Retrieve detailed paper metadata alongside associated notes for comprehensive research.
Add Notes: Seamlessly add or update notes on specific papers, enriching your digital library with your insights.
Request Summaries: Generate concise summaries of selected papers, streamlining the review process.

These functionalities align with MCP's core design principles, facilitating a uniform interaction model among diverse AI applications and tools. By adopting Zotero MCP Server, developers can maintain high-level consistency across different platforms while enriching their AI application's data handling capabilities.

⚙️ MCP Architecture & Protocol Implementation

The architecture of the Zotero MCP Server is built around a well-defined protocol that ensures compatibility with various MCP clients. This implementation details how data flows between the client, server, and Zotero library to support seamless integration. The key components include:

MCP Client: Sends requests and receives responses via the defined protocol.
MCP Server: Processes these requests, interacts with Zotero API, and returns appropriate results.
Data Source/Tool: Represents the Zotero repository itself, ensuring data consistency and up-to-date integrity.
