LinkedIn Agent is an open-source command-line tool powered by the OpenAI API to automate various LinkedIn tasks. It generates personalized connection request messages based on target profiles, crafts follow-up sequences to nurture relationships, and endorses skills with context-aware comments. The agent can extract profile data, such as current roles and experiences, to tailor outreach, and supports bulk campaign execution by processing CSV lists of targets. Users define templates or rely on AI-generated content, while adjusting tone and length through parameters. The tool handles authentication, session management, and rate limits, ensuring smooth operation. By integrating AI-driven messaging with LinkedIn's network interface, it dramatically accelerates business development, recruitment, and personal branding efforts.
