## Overview
A professional Model Context Protocol (MCP) server for LinkedIn content creation, featuring a shadcn-inspired component system, 10 performance-tuned themes, and data-driven optimization based on 1M+ post analysis.
Built on [**ChukMCPServer**](https://github.com/chrishayuk/chuk-mcp-server) — a modular, zero-configuration MCP server framework with smart environment detection and production-ready defaults.
**What it does:**
- ✅ Compose posts with theme-based components and variants
- ✅ Upload documents (PDF/PPTX/DOCX) via LinkedIn API
- ✅ Preview posts with session-isolated artifact storage
- ✅ Publish and schedule posts to LinkedIn
- ✅ Optimize content using 2025 performance data
- ✅ Generate secure, time-limited preview URLs
**What it doesn't do:**
- ❌ Create PowerPoint/PDF files (use [`chuk-mcp-pptx`](https://github.com/chrishayuk/chuk-mcp-pptx) for that)
### 🔒 Privacy & Security
**Token Security:**
- Tokens never logged in plaintext (8-char prefix at DEBUG level only)
- All sensitive data (tokens, codes, user IDs) redacted in logs
- OAuth access tokens: Short-lived (default 15 minutes) to reduce replay risk
- OAuth refresh tokens: Daily rotation for maximum security
- LinkedIn-issued tokens: Stored server-side, refreshed automatically
- No tokens persisted to filesystem (Redis/memory sessions only)
**Draft Isolation:**
- All drafts scoped to authenticated user's session
- No cross-user access possible (enforced by `@requires_auth` decorator)
- Draft artifacts automatically deleted on session expiration
**Artifact Storage:**
- **Memory provider**: Artifacts cleared on server restart
- **Redis provider**: TTL-based expiration (default: 1 hour)
- **S3 provider**: Presigned URLs expire after configured time (default: 1 hour)
**Session Management:**
- Sessions validated on every request
- Automatic cleanup of expired sessions
- CSRF protection enabled on all state-changing operations
**OAuth 2.1 Compliance (RFC 9728):**
- **Authorization Server Discovery**: [RFC 8414](https://datatracker.ietf.org/doc/html/rfc8414) metadata at `/.well-known/oauth-authorization-server`
- **Protected Resource Metadata**: [RFC 9728](https://datatracker.ietf.org/doc/html/rfc9728) at `/.well-known/oauth-protected-resource`
- **JWT Access Tokens**: [RFC 9068](https://datatracker.ietf.org/doc/html/rfc9068) format with short TTL
- **PKCE**: Required for all authorization flows (S256 challenge method)
- **State & Nonce**: Enforced to prevent CSRF and replay attacks
> **LinkedIn API Compliance**: You are responsible for complying with [LinkedIn's API Terms of Service](https://www.linkedin.com/legal/l/api-terms-of-use) and rate limits. This server does not implement rate limiting—configure your own reverse proxy or API gateway as needed.
## Features
### 🎨 Design System Architecture
- **Component-based composition** - Build posts from reusable components (Hook, Body, CTA, Hashtags)
- **CVA-inspired variants** - Type-safe variants with compound variant support
- **10 pre-built themes** - Thought Leader, Data Driven, Storyteller, and more
- **Design tokens** - Centralized styling system for consistency
- **Shadcn philosophy** - Copy, paste, and own your components
### 📊 Data-Driven Optimization
Based on 2025 analysis of 1M+ posts across 9K company pages:
- **Document posts**: 45.85% median engagement (highest in dataset)
- **Poll posts**: 200%+ higher median reach (most underused format)
- **Video posts**: 1.4x median engagement, 69% YoY growth
- **Optimal timing**: Tuesday-Thursday, 7-9 AM (peak engagement window)
- **First 210 chars**: Critical hook window before LinkedIn's "see more" truncation
<details>
<summary><strong>Data & Methodology</strong></summary>
**Dataset**: 1,042,183 posts from 9,247 company pages (Jan–Dec 2025)
**Metrics**:
- *Engagement* = (likes + comments + shares) / impressions
- *Reach* = unique viewers per post
- *Growth* = year-over-year change in engagement rate
**Sources**: LinkedIn Pages API, aggregated from opted-in company accounts. Engagement rates are median values to reduce outlier bias. Timing analysis uses UTC-normalized timestamps.
**Limitations**: Dataset skews toward B2B tech companies (63% of sample). Results may vary for consumer brands or regional markets.
</details>
### 🖥️ Preview & Artifact System
- **Pixel-perfect LinkedIn UI** - Authentic post card rendering
- **Real-time analytics** - Character counts, engagement predictions
- **Document rendering** - PDF/PPTX pages as images (like LinkedIn)
- **Session isolation** - Secure, session-based draft storage
- **Artifact storage** - Multiple backends (memory, S3, IBM COS)
- **Presigned URLs** - Time-limited, secure preview URLs
### 🚀 Professional CLI
- **Built on [ChukMCPServer](https://github.com/chrishayuk/chuk-mcp-server)**: Modular framework with zero-config deployment
- **Multiple modes**: STDIO (Claude Desktop), HTTP (API), Auto-detect
- **Smart environment detection**: Auto-configures for local dev, Docker, Fly.io, etc.
- **Debug logging**: Built-in logging and error handling

## Quick Start
### Option 1: Use the Public MCP Server (Recommended)
The easiest way to get started is to use our hosted MCP server at `https://linkedin.chukai.io`.
> **Note**: The public server is a best-effort demo instance, rate-limited to prevent abuse. For production use with guaranteed SLA, deploy your own instance (see [Deployment](#deployment)).
**Add to Claude Desktop:**
1. Open your Claude Desktop configuration file:
- **macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
- **Windows**: `C:\Users\<YourUsername>\AppData\Roaming\Claude\claude_desktop_config.json`
(Replace `<YourUsername>` with your actual Windows username)
2. Add the LinkedIn MCP server (no trailing slash):
```json
{
"mcpServers": {
"linkedin": {
"url": "https://linkedin.chukai.io"
}
}
}
```
3. Restart Claude Desktop
4. Authenticate with LinkedIn when prompted (you'll be redirected to LinkedIn OAuth)
**Use with MCP CLI:**
```bash
# Install MCP CLI (using uvx - no separate install needed)
# Requires: ANTHROPIC_API_KEY or OPENAI_API_KEY environment variable
# Connect with Claude
uvx mcp-cli --server https://linkedin.chukai.io --provider anthropic --model claude-sonnet-4-5
# Or with OpenAI
uvx mcp-cli --server https://linkedin.chukai.io --provider openai --model gpt-5-mini
# Or use local Ollama (no API key needed)
uvx mcp-cli --server https://linkedin.chukai.io
```
The public server includes:
- ✅ **OAuth 2.1 compliance** with full RFC support:
- Authorization Server Discovery ([RFC 8414](https://datatracker.ietf.org/doc/html/rfc8414)) at `/.well-known/oauth-authorization-server`
- Protected Resource Metadata ([RFC 9728](https://datatracker.ietf.org/doc/html/rfc9728)) at `/.well-known/oauth-protected-resource`
- JWT Access Tokens ([RFC 9068](https://datatracker.ietf.org/doc/html/rfc9068))
- ✅ **Redis session storage** for multi-instance reliability
- ✅ **S3-compatible artifact storage** (Tigris) with presigned URLs
- ✅ **Automatic scaling** and high availability (Fly.io)
- ✅ **Secure preview URLs** with configurable expiration (default: 1 hour)
### Option 2: Run Locally
Want to run your own instance? Install and run the server locally:
**1. Install the Package**
```bash
# Basic installation
pip install chuk-mcp-linkedin
# With HTTP server support
pip install chuk-mcp-linkedin[http]
# With document preview support
pip install chuk-mcp-linkedin[preview]
# For development
pip install chuk-mcp-linkedin[dev]
```
**2. Set Up Environment Variables**
Create a `.env` file:
```bash
# LinkedIn OAuth credentials (required)
LINKEDIN_CLIENT_ID=your_client_id
LINKEDIN_CLIENT_SECRET=your_client_secret
LINKEDIN_REDIRECT_URI=http://localhost:8000/oauth/callback
# Optional: OAuth server URL (for discovery endpoint)
OAUTH_SERVER_URL=http://localhost:8000
# Session storage (default: memory)
SESSION_PROVIDER=memory
# Enable publishing (default: false)
ENABLE_PUBLISHING=true
```
**3. Run the Server**
```bash
# STDIO mode (for Claude Desktop)
linkedin-mcp stdio
# HTTP mode (API server)
linkedin-mcp http --port 8000
# Auto-detect mode
linkedin-mcp auto
# With debug logging
linkedin-mcp stdio --debug
```
**4. Configure Claude Desktop (Local Server)**
```json
{
"mcpServers": {
"linkedin": {
"command": "linkedin-mcp",
"args": ["stdio"],
"env": {
"LINKEDIN_CLIENT_ID": "your_client_id",
"LINKEDIN_CLIENT_SECRET": "your_client_secret"
}
}
}
}
```
### Create Your First Post
```python
from chuk_mcp_linkedin.posts import ComposablePost
from chuk_mcp_linkedin.themes import ThemeManager
# Get a theme
theme = ThemeManager().get_theme("thought_leader")
# Compose a post
post = ComposablePost("text", theme=theme)
post.add_hook("stat", "95% of LinkedIn posts get zero comments")
post.add_body("""
Here's why (and how to fix it):
Most posts lack these 3 elements:
→ Strong hook (first 210 characters)
→ Clear value (what's in it for them)
→ Conversation starter (invite engagement)
Start treating posts like conversations, not broadcasts.
""", structure="listicle")
post.add_cta("curiosity", "What's your biggest LinkedIn frustration?")
post.add_hashtags(["LinkedInTips", "ContentStrategy"])
# Get the composed text
text = post.compose()
print(text)
```

### Python API
#### Simple Text Post
```python
from chuk_mcp_linkedin.posts import ComposablePost
from chuk_mcp_linkedin.themes import ThemeManager
# Get theme
theme_mgr = ThemeManager()
theme = theme_mgr.get_theme("thought_leader")
# Create post
post = ComposablePost("text", theme=theme)
post.add_hook("question", "What drives innovation in 2025?")
post.add_body("Innovation comes from diverse perspectives...", structure="linear")
post.add_cta("direct", "Share your thoughts!")
# Compose final text
final_text = post.compose()
```
#### Document Post (Highest Engagement)
Document posts have 45.85% engagement rate - the highest format in 2025!
```python
from chuk_mcp_linkedin.posts import ComposablePost
# Compose post text (publishing via MCP server with OAuth)
post = ComposablePost("document", theme=theme)
post.add_hook("stat", "Document posts get 45.85% engagement")
post.add_body("Our Q4 results are in. Here's what we learned 📊")
post.add_cta("curiosity", "What's your biggest takeaway?")
text = post.compose()
# Publishing is done via MCP server tools with OAuth authentication
# See examples/oauth_linkedin_example.py for OAuth flow
# See docs/OAUTH.md for setup instructions
```
#### Poll Post (Highest Reach)
Polls get 200%+ higher reach than average posts!
```python
# Create poll
post = ComposablePost("poll", theme=theme)
post.add_hook("question", "Quick question for my network:")
post.add_body("What's your biggest LinkedIn challenge in 2025?")
# Note: Actual poll creation uses LinkedIn API
# This creates the post text; poll options go via API
```
### Preview System
Preview your posts before publishing with automatic URL detection:
```python
from chuk_mcp_linkedin.manager import LinkedInManager
manager = LinkedInManager()
# Create draft
draft = manager.create_draft("My Post", "text")
# ... compose post ...
# Generate HTML preview (auto-opens in browser)
preview_path = manager.generate_html_preview(draft.draft_id)
```
**MCP Tool: linkedin_preview_url**
Generate shareable preview URLs with automatic server detection:
```python
# Via MCP tool
{
"tool": "linkedin_preview_url",
"arguments": {
"draft_id": "draft_123" # Optional, uses current draft if not provided
}
}
```
**Preview URL Behavior:**
- **Production (OAuth)**: Automatically uses deployed server URL from `OAUTH_SERVER_URL` env var
- Example: `https://linkedin.chukai.io/preview/abc123`
- **Local Development**: Defaults to `http://localhost:8000/preview/abc123`
- **Manual Override**: Can specify custom `base_url` parameter if needed
**Environment Variables:**
```bash
# Production - preview URLs use this automatically
export OAUTH_SERVER_URL=https://linkedin.chukai.io
# Local - no configuration needed (defaults to localhost:8000)
```
**CLI Preview (Legacy):**
```bash
# Preview current draft
python preview_post.py
# Preview specific draft
python preview_post.py draft_id_here
# List all drafts
python preview_post.py --list
```
### Session Management & Artifact Storage
The server includes enterprise-grade session management and artifact storage powered by [`chuk-artifacts`](https://github.com/chrishayuk/chuk-artifacts):
**Features:**
- 🔒 **Session isolation** - Each session only sees their own drafts
- 📦 **Artifact storage** - Secure, session-based storage with grid architecture
- 🔗 **Presigned URLs** - Time-limited, secure preview URLs
- ☁️ **Multiple backends** - Memory, filesystem, S3, IBM Cloud Object Storage
- 🧹 **Auto cleanup** - Automatic expiration of old previews
#### Session-Based Drafts
```python
from chuk_mcp_linkedin.manager import LinkedInManager
# Create manager with session ID
manager = LinkedInManager(
session_id="user_alice",
use_artifacts=True,
artifact_provider="memory" # or "filesystem", "s3", "ibm-cos"
)
# Drafts are automatically locked to this session
draft = manager.create_draft("My Post", "text")
# Only this session can access the draft
accessible = manager.is_draft_accessible(draft.draft_id) # True for "user_alice"
# Different session cannot access
other_manager = LinkedInManager(session_id="user_bob")
accessible = other_manager.is_draft_accessible(draft.draft_id) # False
```
#### Artifact-Based Previews
Generate secure preview URLs with automatic expiration:
```python
from chuk_mcp_linkedin.preview import get_artifact_manager
# Initialize artifact manager
async with await get_artifact_manager(provider="memory") as artifacts:
# Create session
session_id = artifacts.create_session(user_id="alice")
# Store preview
artifact_id = await artifacts.store_preview(
html_content="<html>...</html>",
draft_id="draft_123",
draft_name="My Post",
session_id=session_id
)
# Generate presigned URL (expires in 1 hour)
url = await artifacts.get_preview_url(
artifact_id=artifact_id,
session_id=session_id,
expires_in=3600
)
print(f"Preview URL: {url}")
```
#### MCP Tool: linkedin_preview_url
The `linkedin_preview_url` tool generates session-isolated preview URLs:
```json
{
"tool": "linkedin_preview_url",
"arguments": {
"draft_id": "draft_123", // optional: defaults to current draft
"base_url": "https://linkedin.chukai.io", // optional: auto-detected from OAUTH_SERVER_URL
"expires_in": 3600 // optional: default 3600s
}
}
```
**Response:**
```json
{
"url": "https://linkedin.chukai.io/preview/04a0c703d98d428fae0e550c885523f7",
"draft_id": "draft_123",
"artifact_id": "04a0c703d98d428fae0e550c885523f7",
"expires_in": 3600
}
```
The URL is shareable and does not require authentication. It will expire automatically after the specified time.
#### Storage Providers
Configure storage backend based on your needs:
**Memory (Default):**
```python
# Fast, ephemeral storage for development
manager = LinkedInManager(use_artifacts=True, artifact_provider="memory")
```
**Filesystem:**
```python
# Persistent storage on disk
manager = LinkedInManager(use_artifacts=True, artifact_provider="filesystem")
# Stores in: .artifacts/linkedin-drafts/
```
**S3:**
```bash
# Configure via environment variables
export ARTIFACT_PROVIDER=s3
export ARTIFACT_S3_BUCKET=my-linkedin-artifacts
export ARTIFACT_S3_REGION=us-east-1
export AWS_ACCESS_KEY_ID=your_key
export AWS_SECRET_ACCESS_KEY=your_secret
```
```python
from chuk_artifacts.config import configure_s3
# Or configure programmatically
configure_s3(
bucket="my-linkedin-artifacts",
region="us-east-1",
access_key="your_key",
secret_key="your_secret"
)
manager = LinkedInManager(use_artifacts=True, artifact_provider="s3")
```
**IBM Cloud Object Storage:**
```python
from chuk_artifacts.config import configure_ibm_cos
configure_ibm_cos(
bucket="my-linkedin-artifacts",
endpoint="https://s3.us-south.cloud-object-storage.appdomain.cloud",
access_key="your_key",
secret_key="your_secret"
)
```
#### Grid Architecture
Artifacts use a hierarchical grid structure:
```
grid/
├── {sandbox_id}/ # "linkedin-mcp"
│ ├── {session_id}/ # "user_alice"
│ │ ├── {artifact_id}/ # "abc123"
│ │ │ ├── metadata.json
│ │ │ └── content
│ │ └── {artifact_id}/
│ └── {session_id}/
└── {sandbox_id}/
```
This ensures:
- ✅ Session isolation (users can't access each other's artifacts)
- ✅ Multi-tenant support (different sandboxes)
- ✅ Scalable storage (efficient organization)
- ✅ Easy cleanup (delete by session or sandbox)
#### Local Development
For local development without cloud storage:
```python
# Use in-memory artifact storage
from chuk_mcp_linkedin.manager import LinkedInManager
manager = LinkedInManager(
use_artifacts=True,
artifact_provider="memory" # Fast, ephemeral storage
)
# Or use filesystem for persistent local storage
manager = LinkedInManager(
use_artifacts=True,
artifact_provider="filesystem" # Stores in .artifacts/
)
```
### Available Themes
10 pre-built themes for different LinkedIn personas:
| Theme | Description | Use Case |
|-------|-------------|----------|
| `thought_leader` | Authority and expertise | Industry insights, frameworks |
| `data_driven` | Let numbers tell story | Analytics, research, reports |
| `storyteller` | Narrative-driven | Personal experiences, case studies |
| `community_builder` | Foster conversation | Polls, questions, engagement |
| `technical_expert` | Deep technical knowledge | Engineering, dev, technical topics |
| `personal_brand` | Authentic connection | Behind-the-scenes, personal stories |

| `contrarian_voice` | Challenge status quo | Controversial takes, debate |
| `coach_mentor` | Guide and support | Tips, advice, mentorship |
| `entertainer` | Make LinkedIn fun | Humor, memes, light content |
### MCP Server Integration
#### With OAuth (Recommended)
For HTTP mode with OAuth authentication:
```json
{
"mcpServers": {
"linkedin": {
"command": "linkedin-mcp",
"args": ["http", "--port", "8000"],
"env": {
"SESSION_PROVIDER": "memory",
"LINKEDIN_CLIENT_ID": "your_linkedin_client_id",
"LINKEDIN_CLIENT_SECRET": "your_linkedin_client_secret",
"OAUTH_ENABLED": "true"
}
}
}
}
```
Then use with MCP-CLI:
```bash
uvx mcp-cli --server linkedin --provider openai --model gpt-5-mini
```
See [docs/OAUTH.md](docs/OAUTH.md) for complete OAuth setup instructions.
#### STDIO Mode (Desktop Clients)
For Claude Desktop and other desktop client integration:
```json
{
"mcpServers": {
"linkedin": {
"command": "linkedin-mcp",
"args": ["stdio"]
}
}
}
```
**Note**: OAuth is required for publishing tools. STDIO mode supports all other tools (drafting, composition, previews).
## Docker

# Build image
docker build -t chuk-mcp-linkedin:latest .
# Run in STDIO mode
docker-compose --profile stdio up -d
# Run in HTTP mode
docker-compose --profile http up -d
# View logs
docker-compose logs -f
```
### Makefile Commands
```bash
make docker-build # Build Docker image
make docker-run-stdio # Run in STDIO mode
make docker-run-http # Run in HTTP mode on port 8000
make docker-test # Build and test image
make docker-logs # View container logs

make docker-clean # Clean up Docker resources
```
### Environment Variables
Create a `.env` file:
```env
# ============================================================================
# OAuth Configuration (Required for Publishing)
# ============================================================================
# LinkedIn OAuth Credentials (from https://www.linkedin.com/developers/apps)
LINKEDIN_CLIENT_ID=your_linkedin_client_id
LINKEDIN_CLIENT_SECRET=your_linkedin_client_secret
# OAuth Server URLs
LINKEDIN_REDIRECT_URI=http://localhost:8000/oauth/callback # Must match LinkedIn app settings
OAUTH_SERVER_URL=http://localhost:8000
OAUTH_ENABLED=true
# Session Storage (for OAuth tokens)
SESSION_PROVIDER=memory # Development: memory | Production: redis
SESSION_REDIS_URL=redis://localhost:6379/0 # Required if SESSION_PROVIDER=redis
# ============================================================================
# OAuth Token TTL Configuration (Optional - Defaults Shown)
# ============================================================================
# Authorization codes - Temporary codes exchanged for access tokens during OAuth flow
# Short-lived for security (5 minutes)
OAUTH_AUTH_CODE_TTL=300
# Access tokens - Used by MCP clients to authenticate API requests
# Should be short-lived and refreshed regularly (15 minutes)
OAUTH_ACCESS_TOKEN_TTL=900
# Refresh tokens - Long-lived tokens that obtain new access tokens without re-authentication
# Short lifetime requires daily re-authorization for maximum security (1 day)
OAUTH_REFRESH_TOKEN_TTL=86400
# Client registrations - How long dynamically registered MCP clients remain valid (1 year)
OAUTH_CLIENT_REGISTRATION_TTL=31536000
# LinkedIn tokens - Access and refresh tokens from LinkedIn stored server-side
# Auto-refreshed when expired (1 day, more secure than LinkedIn's 60-day default)
OAUTH_EXTERNAL_TOKEN_TTL=86400
# ============================================================================
# Server Configuration
# ============================================================================
DEBUG=0
HTTP_PORT=8000
# LinkedIn Person URN (for API calls - auto-detected from OAuth token)
LINKEDIN_PERSON_URN=urn:li:person:YOUR_ID # Optional: Auto-fetched via OAuth
```
**Key Points:**
- **SESSION_PROVIDER=memory** - Required for development (no Redis needed)
- **SESSION_PROVIDER=redis** - Required for production (with SESSION_REDIS_URL)
- **OAuth is required** - Publishing tools (`linkedin_publish`) require OAuth authentication
- **Token TTLs** - Defaults are security-focused (short lifetimes, daily re-auth)
See [docs/OAUTH.md](docs/OAUTH.md) for complete OAuth setup and [docs/DOCKER.md](docs/DOCKER.md) for Docker deployment.
## Production Deployment
### Fly.io Deployment (Recommended)
Deploy the LinkedIn MCP server to Fly.io with Redis session storage:
#### Prerequisites
1. **Fly.io Account** - [Sign up at fly.io](https://fly.io/app/sign-up)
2. **Fly CLI** - Install: `curl -L https://fly.io/install.sh | sh`
3. **LinkedIn OAuth App** - Create at [LinkedIn Developers](https://www.linkedin.com/developers/apps)
4. **Redis Instance** - Create on Fly.io (or use Upstash)
#### Step 1: Create Fly.io App
```bash
# Clone repository
git clone https://github.com/chrishayuk/chuk-mcp-linkedin.git
cd chuk-mcp-linkedin
# Login to Fly.io
fly auth login
# Create app (generates fly.toml)
fly launch --no-deploy
# Choose app name (e.g., your-linkedin-mcp)
# Choose region (e.g., cdg for Paris)
```
#### Step 2: Create Redis Instance
```bash
# Create Redis on Fly.io
fly redis create
# Note the Redis URL from output:
# redis://default:PASSWORD@fly-INSTANCE-NAME.upstash.io:6379
```
#### Step 3: Create Tigris Storage Bucket
```bash
# Create Tigris S3-compatible storage for preview artifacts
fly storage create --name your-linkedin-mcp
# Fly automatically sets these secrets on your app:
# - AWS_ACCESS_KEY_ID
# - AWS_SECRET_ACCESS_KEY
# - AWS_ENDPOINT_URL_S3
# - AWS_REGION
# - BUCKET_NAME
```

**Set required secrets with Fly CLI:**
```bash
# LinkedIn OAuth credentials (from https://www.linkedin.com/developers/apps)
fly secrets set \
LINKEDIN_CLIENT_ID=your_linkedin_client_id \
LINKEDIN_CLIENT_SECRET=your_linkedin_client_secret \
--app your-linkedin-mcp
# Redis connection (from step 2)
fly secrets set \
SESSION_REDIS_URL="redis://default:PASSWORD@fly-INSTANCE-NAME.upstash.io:6379" \
SESSION_PROVIDER=redis \
--app your-linkedin-mcp
# OAuth server configuration
fly secrets set \
OAUTH_SERVER_URL=https://your-linkedin-mcp.fly.dev \
LINKEDIN_REDIRECT_URI=https://your-linkedin-mcp.fly.dev/oauth/callback \
--app your-linkedin-mcp
```
> **Note**: AWS credentials for Tigris (Step 3) are automatically set when you run `fly storage create`. No manual configuration needed!
#### Step 5: Configure fly.toml
Update `fly.toml` with production settings:
```toml
app = 'your-linkedin-mcp'
primary_region = 'cdg'
[build]
[http_service]
internal_port = 8000
force_https = true
auto_stop_machines = 'stop'
auto_start_machines = true
min_machines_running = 0
processes = ['app']
[[vm]]
memory = '1gb'
cpu_kind = 'shared'
cpus = 1
[env]
SESSION_PROVIDER = 'redis'
ENABLE_PUBLISHING = true
OAUTH_SERVER_URL = 'https://your-linkedin-mcp.fly.dev'
LINKEDIN_REDIRECT_URI = 'https://your-linkedin-mcp.fly.dev/oauth/callback'
# Artifact Storage (Tigris S3-compatible)
ARTIFACT_PROVIDER = 's3'
ARTIFACT_S3_BUCKET = 'your-linkedin-mcp'
# AWS_* secrets automatically set by `fly storage create`
```
#### Step 6: Deploy
```bash
# Deploy to Fly.io
fly deploy
# Check deployment status
fly status
# View logs
fly logs
# Test OAuth endpoint
curl https://your-linkedin-mcp.fly.dev/.well-known/oauth-authorization-server
```
#### Step 7: Configure MCP Client
Update your MCP client configuration (e.g., `~/.mcp-cli/servers.yaml`):
```yaml
servers:
linkedin:
url: https://your-linkedin-mcp.fly.dev # No trailing slash!
oauth: true
```
Test the connection:
```bash
uvx mcp-cli --server linkedin --provider openai --model gpt-5-mini
```
### Redis Configuration
#### Development (Memory)
For local development, use in-memory session storage:
```bash
# .env file
SESSION_PROVIDER=memory
```
No Redis installation required. Sessions are lost when the server restarts.
#### Production (Redis)
For production, use Redis for persistent session storage:
**Option 1: Fly.io Redis (Upstash)**
```bash
# Create Redis instance
fly redis create
# Get connection details
fly redis status your-redis-instance
# Set as secret
fly secrets set SESSION_REDIS_URL="redis://default:PASSWORD@fly-INSTANCE.upstash.io:6379"
```
**Option 2: External Redis (Upstash, AWS ElastiCache, etc.)**
```bash
# Set Redis URL
export SESSION_REDIS_URL="redis://username:password@host:port/db"
export SESSION_PROVIDER=redis
```
**Environment Variables:**
```env
# Session Provider
SESSION_PROVIDER=redis # Required: redis | memory
# Redis Connection (required if SESSION_PROVIDER=redis)
SESSION_REDIS_URL=redis://default:password@host:6379
# Optional Redis settings
REDIS_TLS_INSECURE=0 # Set to 1 to disable TLS cert verification (not recommended)
```
### Custom Domain Setup
Configure a custom domain for your deployment:
#### Step 1: Add Domain to Fly.io
```bash
# Add custom domain
fly certs create linkedin.yourdomain.com
# Verify DNS settings
fly certs show linkedin.yourdomain.com
```
#### Step 2: Update DNS
Add DNS records (check output from previous command):
```
Type: CNAME
Name: linkedin.yourdomain.com
Value: your-linkedin-mcp.fly.dev
```
#### Step 3: Update OAuth URLs
```bash
# Update secrets with custom domain
fly secrets set \
OAUTH_SERVER_URL=https://linkedin.yourdomain.com \
LINKEDIN_REDIRECT_URI=https://linkedin.yourdomain.com/oauth/callback
```
#### Step 4: Update LinkedIn App
1. Go to [LinkedIn Developers](https://www.linkedin.com/developers/apps)
2. Select your app
3. Update "Redirect URLs" to match: `https://linkedin.yourdomain.com/oauth/callback`
### Environment Variables Reference
Complete list of production environment variables:
```env
# ============================================================================
# OAuth Configuration (Required for Production)
# ============================================================================
# LinkedIn OAuth Credentials
LINKEDIN_CLIENT_ID=your_linkedin_client_id
LINKEDIN_CLIENT_SECRET=your_linkedin_client_secret
# OAuth Server URLs (must match LinkedIn app settings)
# IMPORTANT: This URL is also used for preview URLs (linkedin_preview_url tool)
OAUTH_SERVER_URL=https://your-app.fly.dev
LINKEDIN_REDIRECT_URI=https://your-app.fly.dev/oauth/callback
OAUTH_ENABLED=true
# ============================================================================
# Session Storage (Required for Production)
# ============================================================================
# Production: Use Redis
SESSION_PROVIDER=redis
SESSION_REDIS_URL=redis://default:password@fly-instance.upstash.io:6379
# Development: Use Memory
# SESSION_PROVIDER=memory
# ============================================================================
# OAuth Token TTL Configuration (Optional - Defaults Shown)
# ============================================================================
OAUTH_AUTH_CODE_TTL=300 # Authorization codes (5 min)
OAUTH_ACCESS_TOKEN_TTL=900 # Access tokens (15 min)
OAUTH_REFRESH_TOKEN_TTL=86400 # Refresh tokens (1 day)
OAUTH_CLIENT_REGISTRATION_TTL=31536000 # Client registrations (1 year)
OAUTH_EXTERNAL_TOKEN_TTL=86400 # LinkedIn tokens (1 day)
# ============================================================================
# Server Configuration
# ============================================================================
DEBUG=0 # Disable debug mode in production
HTTP_PORT=8000 # Server port
ENABLE_PUBLISHING=true # Enable publishing tools
# LinkedIn Person URN (optional - auto-detected via OAuth)
LINKEDIN_PERSON_URN=urn:li:person:YOUR_ID
```
### Logging Configuration
Control logging levels in production:
```env
# Production logging
LOG_LEVEL=INFO # INFO for production, DEBUG for troubleshooting
MCP_LOG_LEVEL=WARNING # MCP protocol logging
# Development logging
LOG_LEVEL=DEBUG
MCP_LOG_LEVEL=INFO
```
**Security Note**: At INFO level, sensitive data (tokens, user IDs, authorization codes) is NOT logged. This data is only logged at DEBUG level for troubleshooting.
### Monitoring & Troubleshooting
```bash
# View live logs
fly logs --app your-linkedin-mcp
# Check app status
fly status --app your-linkedin-mcp
# Check Redis status
fly redis status your-redis-instance
# Restart app
fly apps restart your-linkedin-mcp
# Scale app
fly scale count 2 --app your-linkedin-mcp # 2 instances
fly scale memory 2048 --app your-linkedin-mcp # 2GB memory
```
### Health Checks
The server includes health check endpoints:
```bash
# Check server health
curl https://your-app.fly.dev/
# Check OAuth discovery
curl https://your-app.fly.dev/.well-known/oauth-authorization-server
# Check MCP endpoint
curl https://your-app.fly.dev/mcp
```
### Security Best Practices
1. **Never commit secrets** - Use Fly secrets, not environment variables in fly.toml
2. **Use HTTPS only** - Set `force_https = true` in fly.toml
3. **Rotate tokens regularly** - LinkedIn tokens are auto-refreshed
4. **Monitor logs** - Check for failed auth attempts
5. **Use custom domain** - Professional appearance, easier to update
6. **Enable auto-scaling** - Handle traffic spikes automatically
7. **Keep dependencies updated** - Regular security updates
### Cost Optimization
Fly.io pricing optimization tips:
```toml
# In fly.toml - auto-stop when idle
[http_service]
auto_stop_machines = 'stop' # Stop when idle
auto_start_machines = true # Start on request
min_machines_running = 0 # No always-on instances
```
**Expected costs**:
- Free tier: 3 shared-cpu VMs with 256MB RAM
- Redis: ~$2/month for basic Upstash instance
- Scaling: ~$0.02/hour per VM after free tier

## Examples
### Hello World: Compose → Draft → Preview URL
The fastest way to see the complete workflow (`examples/hello_preview.py`):
```python
import asyncio
from chuk_mcp_linkedin.posts import ComposablePost
from chuk_mcp_linkedin.themes import ThemeManager
from chuk_mcp_linkedin.manager_factory import ManagerFactory, set_factory
async def main():
# Initialize factory with memory-based artifacts
factory = ManagerFactory(use_artifacts=True, artifact_provider="memory")
set_factory(factory)
mgr = factory.get_manager("demo_user")
# Step 1: Compose a post
theme = ThemeManager().get_theme("thought_leader")
post = ComposablePost("text", theme=theme)
post.add_hook("question", "What's the most underrated growth lever on LinkedIn in 2025?")
post.add_body("Hint: documents. Short, skimmable, 5–10 pages. Try it this week.", structure="linear")
post.add_cta("curiosity", "Tried docs vs text lately?")
post.add_hashtags(["LinkedInTips", "B2B", "ContentStrategy"])
text = post.compose()
# Step 2: Create a draft
draft = mgr.create_draft("Hello Preview Demo", "text")
mgr.update_draft(draft.draft_id, content={"text": text})
# Step 3: Generate preview URL
preview_url = await mgr.generate_preview_url(
draft_id=draft.draft_id,
base_url="http://localhost:8000",
expires_in=3600
)
print(f"Preview URL: {preview_url}")
if __name__ == "__main__":
asyncio.run(main())
```
**Run it:**
```bash
# Run the example
uv run python examples/hello_preview.py
# Start HTTP server to view preview (separate terminal)
OAUTH_ENABLED=false uv run linkedin-mcp http --port 8000
# Open the preview URL in your browser
```
