Summary
Connects Claude, ChatGPT, Cursor, and Windsurf to 300 million scientific papers with verifiable DOI citations. Exposes five read-only tools: ask_research_question for AI synthesis with inline citations, find_references for fast paper lookup without synthesis, get_research_thread to resume prior conversations, plus collection browsing and account status checks. Supports OAuth and direct Bearer token auth against a single streamable HTTP endpoint. Reach for this when you need research answers backed by real papers instead of hallucinated sources, or when you want sub-second reference lookups filtered by year. Every returned paper includes title, authors, DOI, URL, and abstract snippet. Free tier starts with 50 credits.

SciWeave MCP Server
Ground Claude, ChatGPT, Cursor, and Windsurf in 300M scientific works — every citation a verifiable DOI.
Endpoint: https://mcp.sciweave.com/mcp · Transport: Streamable HTTP · Auth: API key from mcp.sciweave.com (50 free credits to start)
🚀 Install
Claude Code (CLI)
claude mcp add --transport http sciweave https://mcp.sciweave.com/mcp
On first use, Claude Code runs the OAuth flow and asks for your SciWeave API key. For headless / CI setups, pass the token directly:
claude mcp add --transport http sciweave https://mcp.sciweave.com/mcp \
--header "Authorization: Bearer YOUR_API_KEY"

Examples
Ask a research question
Prompt: "What are the latest findings on CRISPR-Cas9 off-target effects in mammalian cells?"
The ask_research_question tool queries SciWeave's index and returns a synthesized answer with numbered citations including authors, journals, DOIs, and publication years.
CRISPR-Cas9 off-target effects in mammalian cells involve several mechanisms...
References (8 sources, 142 total found):
[1] Zhang et al. "Genome-wide off-target analysis..." Nature Methods, 2023
[2] Kim et al. "High-fidelity Cas9 variants..." Science, 2024
...
Browse a research collection
Prompt: "Show me all papers in my Quantum Computing collection"
Claude first calls list_collections to find your collections, then get_collection_papers with the matching ID.
Found 3 research collection(s):
- Quantum Computing (ID: abc123) — 12 papers
- Machine Learning (ID: def456) — 8 papers
12 paper(s) in this collection:
1. Quantum Error Correction with Surface Codes
Authors: Fowler et al. · Year: 2024 · Journal: Physical Review Letters · DOI: 10.1103/...
Fast reference lookup
Prompt: "Find me 5 recent references about mRNA vaccine stability and storage"
find_references is citation-only (no AI synthesis), so results return in ~1 second.
References (5 papers in 1.2s):
[1] Schoenmaker et al. "mRNA-lipid nanoparticle COVID-19 vaccines: Structure and stability"
Year: 2023 · DOI: 10.1016/j.ijpharm.2023.01.015
Snippet: "Storage temperature significantly impacts mRNA integrity..."

Authentication
SciWeave supports two auth modes against the same https://mcp.sciweave.com/mcp endpoint:
- OAuth 2.0 authorization code flow (default for Claude.ai and
claude mcp addwithout headers). Claude opens the SciWeave authorization page, you paste yoursciweave_live_API key, and the server hands back an OAuth access token tied to your account. - Direct Bearer token (Cursor / Windsurf / Claude Desktop / CI). Send
Authorization: Bearer YOUR_API_KEYdirectly. No browser flow.
All tools are read-only — the server cannot write to your collections or modify your account. API keys can be rotated at any time at sciweave.com/settings?tab=api-access.
