group_by

MCP tool from Openalex MCP Server by cyanheads

returns the subset of the filter set OpenAlex can aggregate — raw date fields, .search operators, and from/to range modifiers are excluded

How to use it

Project documentation lists group_by for the Openalex MCP Server MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.

Install Openalex MCP Server

$docker run -e OPENALEX_API_KEY=your-key -p 3010:3010 openalex-mcp-server
