How to Set Up and Use BGPT
BGPT is an MCP server that connects AI assistants to the bgpt.pro scientific paper search engine, which extracts over 25 structured fields โ including methods, sample sizes, results, and limitations โ directly from full-text studies rather than just abstracts. It exposes a single `search_papers` tool that accepts natural-language queries and returns rich, evidence-grounded results, making it ideal for researchers, clinicians, and engineers who need peer-reviewed experimental data in their AI workflows. The free tier provides 50 results with no API key required, and a paid tier via Stripe subscription unlocks higher-volume access.
Prerequisites
- Node.js 18+ installed (for npx transport) or a compatible MCP client that supports SSE transport
- An MCP-compatible client such as Claude Desktop, Cursor, Cline, or Windsurf
- Internet access to reach https://bgpt.pro (no API key needed for free tier; Stripe subscription ID required for paid tier)
- Optional: a bgpt.pro paid subscription for more than 50 results per session
Choose your transport method
BGPT supports two transport options: a cloud SSE endpoint (no local install needed) and a local npx package. For most users the SSE endpoint is the simplest path โ just point your MCP client at https://bgpt.pro/mcp/sse. If you prefer the npx route, ensure Node.js 18+ is available.
# Cloud SSE (recommended โ no local install)
# Use URL: https://bgpt.pro/mcp/sse
# OR local npx
npx -y bgpt-mcpAdd BGPT to Claude Desktop (SSE method)
Open your Claude Desktop configuration file and add the bgpt server entry using the hosted SSE URL. No environment variables are required for the free tier.
{
"mcpServers": {
"bgpt": {
"url": "https://bgpt.pro/mcp/sse"
}
}
}Add BGPT via npx (alternative method)
If you prefer running the server locally via npx, use the command transport instead. This is useful in environments where outbound SSE connections are restricted.
{
"mcpServers": {
"bgpt": {
"command": "npx",
"args": ["-y", "bgpt-mcp"]
}
}
}Add via Claude Code CLI
If you use Claude Code in the terminal, you can register the server directly with the CLI using the SSE transport flag.
claude mcp add bgpt --transport sse https://bgpt.pro/mcp/sseOptionally configure paid-tier access
For more than 50 results, obtain a Stripe subscription at bgpt.pro/mcp and pass your subscription ID as the `api_key` parameter directly in tool invocations. No separate environment variable configuration is needed.
Restart your MCP client and verify
Restart Claude Desktop (or reload your editor). The `search_papers` tool should now appear. Test with a simple query to confirm connectivity.

Example prompts that exercise the search_papers tool with realistic scientific queries.
- "Search for papers on CRISPR delivery mechanisms in neurons published in the last 90 days"
- "Find 5 recent studies on GLP-1 receptor agonists for weight loss, include sample sizes and key results"
- "Search papers about transformer model efficiency improvements and summarize the methods section"
- "Look up evidence-based treatments for antibiotic-resistant UTIs โ focus on RCTs"Troubleshooting BGPT
The search_papers tool returns 0 results or a rate-limit error
The free tier is capped at 50 results per session. If you need more, subscribe at bgpt.pro/mcp and pass the Stripe subscription ID as the api_key parameter in your query.
SSE connection fails or times out in Claude Desktop
Ensure your firewall or corporate proxy allows outbound HTTPS connections to bgpt.pro. As a fallback, switch to the npx transport method which uses stdio instead of SSE.
npx command not found or fails to run
Verify Node.js 18+ is installed with `node --version`. If npx is missing, install it with `npm install -g npx` or upgrade Node.js to a version that bundles it.
