Use hosted MCP or run it yourself

Start with KrytonLabs hosted processing, or point the same MCP runner at your own backend.

🤖 Use in Claude Code

Installs only a dependency-free MCP runner. No npm. Processing uses the KrytonLabs hosted backend with server-side rate limits.

curl -fsSL https://raw.githubusercontent.com/kmanan/opengraph-generator/main/scripts/install-mcp.sh | bash

🐳 Self-host with Docker

Run your own backend. Edit env vars to taste — see .env.example.

docker run -d --name opengraph -p 6736:6736 \
  -e PUBLIC_URL=https://og.yourdomain.com \
  ghcr.io/kmanan/opengraph:latest

Prefer a UI? Add the stack from docker-compose.yml via Portainer and fill in env vars on the form.

⚙️ Use MCP with your backend

Same MCP runner, but processing goes to your self-hosted backend.

curl -fsSL https://raw.githubusercontent.com/kmanan/opengraph-generator/main/scripts/install-mcp.sh | OPENGRAPH_BACKEND=http://localhost:6736 bash
