From 6457be28c58d475121f32fe9434a37b342a82166 Mon Sep 17 00:00:00 2001 From: Bryan Thompson Date: Mon, 23 Feb 2026 10:25:48 -0600 Subject: [PATCH] Add pdf-research plugin with local MCP server First knowledge-work plugin to use a local stdio MCP server instead of a remote HTTP connector. The pdf-server runs locally via npx and provides interactive PDF viewing for academic papers and local files. Tested end-to-end in Claude Code: plugin validation, MCP server connection, tool availability (list_pdfs, display_pdf), and command/skill registration all confirmed working.
