What is the PapersFlow MCP server?
The PapersFlow MCP server is an academic research tool that enables AI agents to search papers, verify citations, discover related research, and visualize citation networks. It provides both free public tools for literature discovery and authenticated tools for deeper research workflows across Claude, Gemini, ChatGPT, and other MCP clients.
PapersFlow integrates academic research capabilities into your AI workflow. Use it to search scholarly literature, verify citations, find papers related to your topic, and explore citation graphs. Public tools are available immediately; additional authenticated tools unlock deeper research features through a PapersFlow account.

PapersFlow MCP server FAQ
It's an academic research tool that integrates paper search, citation verification, and citation graph exploration into AI agents like Claude and Gemini. Public tools work immediately; authenticated tools require a PapersFlow account.
Public tools (search, fetch, verify_citation, find_related_papers, citation graphs) are available immediately. Additional authenticated and paid tools require a PapersFlow account and plan entitlements.
Add the remote MCP endpoint https://doxa.papersflow.ai/mcp to your MCP settings with transport type 'streamable-http'. On first use, your client will open a browser for OAuth sign-in to PapersFlow.
Public tools work without authentication. For authenticated and premium tools, you'll need a PapersFlow account. OAuth sign-in happens automatically on first use.
PapersFlow works with Cline (VS Code), Codex, Claude Code, Gemini CLI, ChatGPT-style hosted MCP apps, and other MCP-compatible clients.

Documentation
Gemini CLI Extension
This repository also includes a root gemini-extension.json so Gemini CLI can install it as an extension wrapper around the hosted MCP server.
Official Gemini CLI flow supported by the docs:
gemini extensions install https://github.com/papersflow-ai/papersflow-mcp
The extension manifest lives at the repository root and points Gemini CLI at the hosted MCP endpoint using Gemini's remote MCP config shape.
If Gemini shows:
papersflow-mcp (from papersflow-mcp) - Disconnected (OAuth not authenticated)
that is expected until OAuth is completed inside Gemini:
/mcp auth papersflow-mcp
/mcp refresh
/mcp list
gemini extensions install installs the extension package. It does not complete OAuth during install. The browser opens when Gemini starts the remote MCP auth flow, typically via /mcp auth papersflow-mcp or the first auth-required connection attempt.

Client Setup
Cline (VS Code)
Add PapersFlow as a remote MCP server in your Cline MCP settings:
{
"mcpServers": {
"papersflow": {
"url": "https://doxa.papersflow.ai/mcp",
"transportType": "streamable-http"
}
}
}
On first use, Cline will open a browser window for OAuth sign-in to your PapersFlow account. Public tools (literature search, citations, paper discovery) work immediately; authenticated tools require a PapersFlow plan.
Other Clients
Supported client paths today:
- Codex
- Claude Code
- Gemini CLI
- ChatGPT-style hosted MCP apps
The setup guide includes both command-style and config-style snippets where supported.
