Security Report
8.2
Low Risk8.2Low RiskThis is a well-structured MCP server for Unpaywall API integration with proper authentication requirements and no dangerous code patterns. The server requires a contact email for API requests (Unpaywall's polite-pool identifier), implements proper input validation, and safely handles third-party API responses. Minor code quality suggestions around error handling do not materially impact security.

Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"unpaywall": {
"url": "https://gateway.pipeworx.io/unpaywall/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 250+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Unpaywall data" })
The gateway picks the right tool and fills the arguments automatically.
