What it does

DocsAgent is an MCP server that searches and edits a Zotero library, an Obsidian vault and, on macOS, Apple Notes from any MCP client. A background C++ engine reads the Zotero database and storage folder, the vault and the Notes store on your machine and keeps a BM25 full-text index with passage ranking; a TypeScript or Python shell exposes eight tools, five for reading and three for writing. Writes to Zotero go through Zotero's local API with a safety gate, and group libraries sync through the Zotero web API. It runs over stdio, or over Streamable HTTP with API-key or OAuth checks for self-hosting. It is the MCP back end that PapersGPT links to.
