Consensus MCP Server | AI Scientific Research

The Consensus MCP server connects AI assistants to Consensus, the academic search engine. Claude, ChatGPT, Cursor, and any MCP-compatible client can search 220M+ peer-reviewed research papers and ground answers in real, citable studies, directly from the conversation.

Why Consensus

• 220M+ papers across medicine, biology, psychology, computer science, economics, and every major field
• Licensed full text: partnerships with leading academic publishers let answers draw on paywalled research you can't get anywhere else
• Powered by Scholar Agent: the Consensus agentic search harness built specifically for research and science. It plans searches, applies quality filters, and weighs evidence the way a trained researcher would
• Search built for research questions: results are ranked for relevance to the question, not keyword overlap
• Rich metadata on every paper: citation counts, study type, sample size, journal quality (SJR quartile), and a key takeaway
• Quality filters: restrict results to RCTs, meta-analyses, human studies, minimum sample sizes, top-quartile journals, and more

2. Select Connectors, then Browse connectors
3. Search for Consensus and click Connect
4. Approve the sign-in with your Consensus account (or continue without one at reduced limits)
5. Ask a research question in any chat; Consensus appears in the tools menu

ChatGPT

One click: open Consensus in the ChatGPT plugin directory and click Connect. Or manually:

1. Open chatgpt.com and sign in
2. Open Plugins from the sidebar
3. Search for Consensus and click Connect
4. Sign in with your Consensus account when prompted
5. Ask a research question, or call it by name: "Use Consensus to find RCTs on..."

Claude Code

claude mcp add --transport http consensus https://mcp.consensus.app/mcp

Codex

codex mcp add consensus --url https://mcp.consensus.app/mcp
codex mcp login consensus

Or add to ~/.codex/config.toml:

[mcp_servers.consensus]
url = "https://mcp.consensus.app/mcp"

Cursor

Or add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "consensus": {
      "command": "npx",
      "args": ["-y", "mcp-remote@latest", "https://mcp.consensus.app/mcp"]
    }
  }
}

VS Code (GitHub Copilot)

Add to your MCP configuration:

{
  "servers": {
    "consensus": {
      "url": "https://mcp.consensus.app/mcp"
    }
  }
}

Everything else

Any client that supports remote MCP servers (Streamable HTTP) works. Point it at:

https://mcp.consensus.app/mcp

The search tool

Search 220M+ academic papers. Returns ranked results with title, authors, journal, publication year, DOI, citation count, study type, a key takeaway, and a link to the paper on Consensus.

Optional filters: publication year and month, study design (RCT, meta-analysis, systematic review, and more), human studies, controlled studies, minimum sample size, journal quality (SJR quartile), minimum citations, open access, clinical guidelines, academic field, and country.

Things to ask

Authentication

Most clients use OAuth: you sign in with your Consensus account the first time you connect. Claude and ChatGPT also work without an account at reduced limits. Paper counts and monthly search limits vary by plan: see consensus.app/pricing. Enterprise customers authenticate with an API key as a Bearer token:

Authorization: Bearer YOUR_API_KEY

For enterprises

Consensus powers research for organizations ranging from universities and research institutions to biotechs and manufacturers. Our team partners with you to bring evidence-grounded search to your users and your internal teams alike: member-facing products, research workflows, internal copilots, custom rate limits, and hands-on integration support.

Consensus API

Building an application instead of connecting a chat client? The same search is available as a REST API at api.consensus.app/v1/search. See the consensus-api repo, the API reference, and API access.

About this repo

The Consensus MCP server is a hosted remote server; there is nothing to install from source. This repo is its public home: setup guides, announcements, and issues. Full documentation lives at docs.consensus.app/docs/mcp.
