DeepSeek++ is a Chrome/Edge/Firefox browser extension that injects agent-style capabilities into the DeepSeek web chat interface. It adds native-like tool calling, Model Context Protocol (MCP) integration, shell command execution, long-term memory, customizable Skills, agent-style continuous execution, and scheduled automation workflows. The extension provides a sidebar interface for persistent agent conversations and acts as an AI workbench layered on top of DeepSeek.
