Publishing to the Gallery

Publishing to the Extensions Gallery requires a complete manifest, a README with usage examples, and passing the Gallery's automated review. The review checks for manifest validity, security concerns (no hardcoded credentials, no excessive permissions), and basic functionality (the MCP server starts and lists tools). The process takes 24-48 hours for first-time publishers and is near-instant for subsequent versions from established publishers.

A strong Gallery listing follows a formula: a clear one-line description, a "quick start" section with the install command and one example prompt, a tools reference listing every tool with its purpose, a configuration section explaining required environment variables, and a troubleshooting section for common issues. The listing is often the user's first and only documentation — if they cannot get the extension working from the Gallery page alone, they will uninstall it.
