+# LinkedIn MCP Server Setup
+
+## Prerequisites
+
+1. **Python 3.12+** on your host machine
+2. **LinkedIn account** with valid credentials
+3. **Create LinkedIn profile locally** (one-time setup)
+
+## Step 1: Install LinkedIn MCP (Host Machine)
+
+Run this on your **host machine** (not in Docker):
+
+```bash
+pip install linkedin-scraper-mcp
+```
+
+## Step 2: Create LinkedIn Profile (One-time Authentication)
+
+Run this command to authenticate and create your profile:
+
+```bash
+linkedin-mcp-server --login
+```
+
+Or use the alternate command:
+
+```bash
+linkedin-scraper-mcp --login
+```
+
+This will:
+- Open a browser window
+- Ask you to log into LinkedIn
+- Handle captcha challenges (manual solving required)
+- Save your session at `~/.linkedin-mcp/profile/`
+
+**Important:** Only one active LinkedIn session is supported. If you need to re-authenticate:
+```bash
+rm -rf ~/.linkedin-mcp/profile
+linkedin-mcp-server --login
+```
+
+## Step 3: Build Docker Image
+
+```bash
+cd /mnt/NVME/Docker/mcp-gateway
+docker compose build linkedin-mcp
+```
+
+## Step 4: Start the Service
+
+```bash
+docker compose up linkedin-mcp
+```
+
+The service is already configured in your `docker-compose.yml` with:
+- Python 3.12 slim image
+- LinkedIn profile mounted from `~/.linkedin-mcp/profile`
+- LOG_LEVEL environment variable from `.env`
+- Automatic restart
+
+## Configuration Options
+
+### Environment Variables (in .env)
+
+```env
+# LinkedIn MCP Server
+LINKEDIN_LOG_LEVEL=INFO
+LINKEDIN_TIMEOUT=10000
+```
+
+### Available Log Levels
+
+- `DEBUG` - Detailed logging
+- `INFO` - Standard logging (recommended)
+- `WARNING` - Only warnings and errors
+- `ERROR` - Only errors
+
+## Docker Integration
+
+The Dockerfile:
+- Uses `python:3.12-slim` as base image
+- Clones the GitHub repository
+- Installs dependencies with pip
+- Mounts profile from host at `~/.linkedin-mcp/profile:/root/.linkedin-mcp/profile`
+
+## Troubleshooting
+
+### Profile Not Found
+```bash
+# Verify profile exists on host
+ls ~/.linkedin-mcp/profile
+
+# Create new profile if missing
+linkedin-mcp-server --login
+```
+
+### Build Fails - Git Clone Issues
+- Ensure you have internet access
+- Check git is installed: `git --version`
+- Try manual clone first: `git clone https://github.com/stickerdaniel/linkedin-mcp-server.git`
+
+### Container Won't Start
+Check the logs:
+```bash
+docker logs mcp-linkedin
+
+# Restart container
+docker compose restart mcp-linkedin
+```
+
+### Session Expired
+LinkedIn sessions may expire. To refresh:
+```bash
+# Delete old profile
+rm -rf ~/.linkedin-mcp/profile
+
+# Create new profile
+linkedin-mcp-server --login
+
+# Restart container
+docker compose restart mcp-linkedin
+```
+
+### Captcha Loop
+If you keep hitting captchas:
+1. Create profile manually on your machine first
+2. Mount that profile into Docker
+3. Run with `--no-headless` temporarily to debug
+
+## Integration with Gateway Proxy
+
+The gateway proxy (`gateway_proxy.py`) should have:
+
+```python
+MCP_BACKEND_LINKEDIN=http://mcp-linkedin:3000/mcp
+```
+
+This is already configured in the docker-compose.yml.
+
+## Verification
+
+Test the connection:
+
+```bash
+# Check if container is running
+docker ps | grep mcp-linkedin
+
+# View logs
+docker logs mcp-linkedin
+
+# Check gateway can reach it
+docker exec mcp-gateway curl http://mcp-linkedin:3000/mcp/tools
+```
+
+## Entry Point
+
+The container runs:
+```
+linkedin-mcp-server --log-level INFO
+```
+
+This starts the MCP server that communicates with the gateway proxy via HTTP.
+
+## Performance Notes
+
+- First run may be slower as Patchright downloads browser dependencies
+- Profile authentication takes 30-60 seconds
+- Subsequent tool calls should respond in 1-5 seconds
+- Browser automation is CPU-intensive; allocate resources accordingly
