BGPT

Search scientific papers from Claude, Cursor, any MCP-compatible AI tool, or plain Python.

BGPT is a remote Model Context Protocol (MCP) server and traditional JSON/HTTP API that gives AI assistants and Python apps access to a database of scientific papers built from full-text studies. Unlike typical search tools that return titles and abstracts, BGPT extracts raw experimental data — methods, results, conclusions, quality scores, sample sizes, limitations, and 25+ metadata fields per paper.

Evidence Demo

If you want to see why BGPT is different from ordinary paper search, start here:

• EVIDENCE_DEMO.md — a claim-interrogation demo for GLP-1 alcohol craving
• examples/bgpt_plotly_evidence_dashboard.py — generate a Plotly HTML dashboard with study methods, samples, limitations, conflicts, data availability, blind spots, and falsifiability prompts
• PROMPT_GALLERY.md — prompts for scientific RAG, literature review agents, and evidence dashboards

The core idea: BGPT helps an AI agent ask what would weaken this scientific claim? before it summarizes the literature.

Quick Start

Use BGPT from Python, REST, or an MCP client — no API key required for the free tier (50 free results).

Option A: Python / REST API

Call the HTTP API directly from any Python script or notebook:

import requests


def search_bgpt(query, num_results=10, days_back=None, api_key=None):
    payload = {"query": query, "num_results": num_results}
    if days_back is not None:
        payload["days_back"] = days_back
    if api_key:
        payload["api_key"] = api_key

    response = requests.post(
        "https://bgpt.pro/api/mcp-search",
        json=payload,
        timeout=30,
    )
    response.raise_for_status()
    return response.json()["results"]


papers = search_bgpt("CRISPR delivery neurons", num_results=5)
print(papers[0]["title"])

Option B: Remote MCP Connection

Most modern MCP clients support direct remote connections. BGPT offers two transports:

Transport	Endpoint
SSE	https://bgpt.pro/mcp/sse
Streamable HTTP	https://bgpt.pro/mcp/stream

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "bgpt": {
      "url": "https://bgpt.pro/mcp/sse"
    }
  }
}

Cursor (.cursor/mcp.json):

{
  "mcpServers": {
    "bgpt": {
      "url": "https://bgpt.pro/mcp/sse"
    }
  }
}

Claude Code (CLI):

claude mcp add bgpt --transport sse https://bgpt.pro/mcp/sse

Cline / Roo Code / Windsurf — same config:

{
  "mcpServers": {
    "bgpt": {
      "url": "https://bgpt.pro/mcp/sse"
    }
  }
}

Tip: If your client supports Streamable HTTP, you can use https://bgpt.pro/mcp/stream instead.

Option C: Via npx (for clients that need a local command)

{
  "mcpServers": {
    "bgpt": {
      "command": "npx",
      "args": ["-y", "bgpt-mcp"]
    }
  }
}

Option D: Install globally

npm install -g bgpt-mcp

Then add to your MCP config:

{
  "mcpServers": {
    "bgpt": {
      "command": "bgpt-mcp"
    }
  }
}

Any MCP Client

Connect to either endpoint:

SSE:              https://bgpt.pro/mcp/sse
Streamable HTTP:  https://bgpt.pro/mcp/stream

That's it. No Docker, no build step.

What You Get

BGPT exposes the same scientific-paper search through an MCP tool and a REST endpoint.

REST endpoint

POST https://bgpt.pro/api/mcp-search

JSON field	Type	Required	Description
query	string	Yes	Search terms (e.g. "CRISPR gene editing efficiency")
num_results	integer	No	Number of results to return (1-100, default 10)
days_back	integer	No	Only return papers published within the last N days
api_key	string	No	Your Stripe subscription ID for paid access

MCP tool

search_papers

Parameter	Type	Required	Description
query	string	Yes	Search terms (e.g. "CRISPR gene editing efficiency")
num_results	integer	No	Number of results to return (1-100, default 10)
days_back	integer	No	Only return papers published within the last N days
api_key	string	No	Your Stripe subscription ID for paid access

What comes back

Each paper result includes 25+ fields, extracted from the full text:

• Title & DOI — standard identifiers
• Methods — experimental design, techniques used
• Results — raw findings, measurements, statistical outcomes
• Conclusions — what the authors determined
• Quality scores — methodological rigor assessment
• Sample sizes — participant/specimen counts
• Limitations — acknowledged weaknesses
• And more — funding, conflicts of interest, study type, etc.

Example

Ask your AI assistant:

"Search for recent papers on CAR-T cell therapy response rates"

BGPT returns structured experimental data your AI can reason over — not just a list of titles.

Pricing

Tier	Cost	Details
Free	$0	50 free results, no API key needed
Pay-as-you-go	$0.02/result	Billed per result returned. Get an API key at bgpt.pro/mcp

BGPT is a hosted remote service — your MCP client connects via SSE or Streamable HTTP, or your app calls the REST endpoint directly. No Docker, scraping, or local index required.

Use Cases

• Literature reviews — Ask your AI to survey a topic with real experimental data
• Python notebooks — Pull recent paper evidence into analysis workflows with one HTTP call
• Evidence synthesis — Ground AI responses in actual study findings
• Research assistance — Find papers by methodology, outcome, or recency
• Fact-checking — Verify claims against published experimental results
• Grant writing — Quickly gather supporting evidence for proposals
