Linkedin Post Agent

This project is a powerful and modular AI agent system that generates and posts professional LinkedIn content using OpenAI and LangChain, built with a clean MCP architecture. It takes an input idea from the user, transforms it into a high-quality LinkedIn post using a custom prompt template, and posts it directly to the user's LinkedIn profile using LinkedIn’s API.

🚀 Features

• ✨ Human-style LinkedIn post generation with strict tone and structure guidelines
• 🧠 LangChain agent powered by OpenAI LLM (gpt-4o)

• 🔧 Built-in LinkedIn posting tool via LinkedIn REST API
• 🖥️ Streamlit frontend for clean user interaction
• 🔄 FastAPI backend for MCP logic orchestration
