## What it does

PapersFlow gives an agent tools for literature search, paper retrieval, citation verification, and related-paper discovery. It can also build citation graphs, inspect neighboring papers, and expand a graph with further connections.

The service runs as a hosted MCP endpoint at `https://doxa.papersflow.ai/mcp`. OAuth handles account access, so the first connection opens a sign-in flow. Public research tools are available after authentication; some authenticated tools depend on a PapersFlow plan.

Claude Code can add the server with one command. Gemini CLI has a repository extension, while Cline uses a remote-server configuration. OAuth must be completed before the connection can operate.
