Summary
This is PapersFlow's production hosted server for academic literature research. It exposes eight tools including search, fetch, verify_citation, find_related_papers, and get_citation_graph for building citation networks and validating references. The service runs at doxa.papersflow.ai/mcp with OAuth protection, so authenticated and paid tools require a PapersFlow account beyond the public search surface. It supports Cline, Codex, Claude Code, Gemini CLI, and other MCP clients over streamable HTTP. Reach for this when you need programmatic access to paper metadata, citation verification, or related work discovery without manually querying academic databases. The OAuth flow opens automatically on first connection in supported clients.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

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.
