Deployment

Host Marketplace on any Node.js platform with the registry built into the artifact.

Requirements

Node.js 20.9 or later.
Outbound HTTPS from the server to every listed store and the AI provider.
A proxy that sets x-forwarded-host (or host) and x-forwarded-proto. The completion route calls its own /api/mcp-transport/http using those headers.

Variable	Effect
`OPENROUTER_API_KEY`, `OPENROUTER_MODEL`	Enable shared AI mode when both are set
`OPENROUTER_MAX_TOKENS`	Output cap, default 4000, must be a positive whole number
`MARKETPLACE_DISABLE_LOCAL_AI`	`true`, `1`, `yes` or `on` forces shared mode and disables `/api/ai-models`
`MARKETPLACE_CUSTOM_AI_ORIGINS`	Comma-separated allowlist for custom AI endpoints

All are optional. With none set each buyer brings their own key.

Edit marketplace.config.json with the stores you trust.

Add the AI variables to your host's secret store.

npm run build, then npm start. The README has Vercel and Railway buttons.

Open GET /api/mcp-transport/http and confirm the admitted store list.

npm test, npm run test:security, npm run test:platform, npm run typecheck, npm run lint, npm run build.
