OpenShorts Releases MCP for Short-Form Video Conversion

Open-source video editing tool OpenShorts has released an MCP (Model Context Protocol) server that integrates with Claude to automatically convert long-form videos into vertical short-form videos. The project was developed based on Claude Code and is designed so that the pipeline operates automatically when users simply input a URL.

The three major technical challenges encountered during development and their solutions are as follows:

• URL Handling and Prompt Design: In the initial version, Claude failed to directly open the provided YouTube link and attempted to perform a web search instead. To resolve this, the server description explicitly stated that 'URLs are passed as-is and the model does not need to verify them first,' thereby prompting the model to invoke the tool immediately.
• Asynchronous Task Processing: Video editing is a long-running task that is difficult to complete within an interactive session. Therefore, an asynchronous architecture was adopted where process_video immediately returns a job id, status is queried via get_job_status, and a webhook_url parameter is supported for integration with external systems.
• Remote Server Authentication (OAuth): Remote MCP servers require RFC 9728 and 8414 metadata issuance, dynamic client registration, and PKCE support. OpenShorts simplified the authentication path by issuing standard API keys under client names, rather than creating a new authentication scheme.
