• 🔒 Secure Authentication: Confluence API token authentication
• ☁️ Fly.io Ready: Optimized for deployment on Fly.io

Tools Available

• confluence_list_spaces - List all available Confluence spaces
• confluence_list_pages - List pages in a specific space
• confluence_create_page - Create new pages from Markdown content
• confluence_update_page - Update existing pages with new content
• confluence_delete_page - Delete pages and clean up cache

Quick Start

1. Installation

git clone <repository-url>
cd confluence-mcp
npm install

2. Configuration

Copy the example environment file and configure your Confluence credentials:

cp .env.example .env

Edit .env with your Confluence details:

CONFLUENCE_BASE_URL=https://your-domain.atlassian.net
CONFLUENCE_USERNAME=your-email@domain.com
CONFLUENCE_API_TOKEN=your-api-token
MCP_API_KEY=your-mcp-api-key
PORT=3001

3. Get Confluence API Token

1. Go to Atlassian Account Settings
2. Click "Create API token"
3. Give it a label and copy the token
4. Use your email as username and the token as password

4. Run the Server

# Development
npm run dev

# Production
npm run build
npm start

The server will be available at http://localhost:3001

Usage Examples

Create a Page from Markdown

# My Documentation

This is a sample page with a Mermaid diagram:

```mermaid
graph TD
    A[Start] --> B[Process]
    B --> C[End]

Some bold text and italic text.

The MCP server will:
1. Convert the Markdown to Confluence storage format
2. Render the Mermaid diagram as a PNG image
3. Create a professionally styled page
4. Cache the mapping for future updates

### Update an Existing Page

When you update a markdown file, the server can automatically update the corresponding Confluence page using the cached mapping.

## API Endpoints

### SSE Endpoints

- `GET /mcp` - Establish SSE connection for MCP protocol
- `POST /messages` - Send MCP messages (requires sessionId)

### Health Check

- `GET /health` - Server health status

## Deployment on Fly.io

### 1. Install Fly CLI

```bash
# macOS
brew install flyctl

# Other platforms: https://fly.io/docs/getting-started/installing-flyctl/

2. Login and Initialize

fly auth login
fly launch

3. Set Secrets

fly secrets set CONFLUENCE_BASE_URL=https://your-domain.atlassian.net
fly secrets set CONFLUENCE_USERNAME=your-email@domain.com
fly secrets set CONFLUENCE_API_TOKEN=your-api-token
fly secrets set MCP_API_KEY=your-mcp-api-key

4. Deploy

fly deploy
