When your AI client's connector asks you to sign in, use the same account you claimed Valency with. That's the account Valency links you to. Your Claude, ChatGPT, or GitHub subscription is a separate account; the email on it may match this one or not. Either way, Valency doesn't use it.

Valency Bond™ is a Model Context Protocol (opens in new tab) (MCP) server that connects AI assistants to preprints from arXiv, bioRxiv, medRxiv, PubMed, and more. It allows Claude, ChatGPT, VS Code, the Antigravity CLI, GitHub Copilot, Grok Build, Kiro, and other MCP-compatible assistants to search, retrieve, and analyze research papers.

How it works

1. You connect your AI assistant to Valency Bond using OAuth (sign in with Google or email)
2. You ask questions like "Find papers about transformer architectures" or "Search for climate change research from 2024"
3. Valency searches tens of millions of papers and returns relevant and accurate results
4. Your AI assistant analyzes and summarizes the findings
