# Castmagic MCP MCP > Castmagic automates content repurposing. Feed it any audio or video URL and get a complete media asset package back automatically. This MCP generates high-accuracy transcripts, polished show notes, social media posts, titles, and more—all from one call to your agent. ## Overview - **Category:** productivity - **Price:** Free - **Tags:** audio-transcription, content-repurposing, show-notes, ai-content-generation, media-processing, social-media-content ## Description You shoot a long video or record a podcast. That content is valuable, but it's also hard to reuse. You shouldn't have to sit there watching the footage just to pull out key quotes or write summaries. This MCP takes full control of that workflow. Connect this service through Vinkius and give your agent the ability to process media directly. It instantly turns hours of video into structured, ready-to-post assets. Need a transcript? Send an audio URL and get speaker identification alongside perfect text. Want marketing copy? Run the transcript through the content generation tools; it spits out show notes, titles, and social posts. You manage your entire library—listing all recordings or deleting old transcripts—all from chat. It’s about making media usable without any manual work. ## Tools ### create_new_transcript This tool sends a new audio or video URL to start the transcription process. ### delete_transcript Use this tool to remove an old transcript and all its associated data from your account. ### get_castmagic_account Retrieves core usage metrics, including your current quota and subscription information. ### get_magic_content Generates AI content like show notes or social posts for a specific transcript ID you provide. ### get_transcript_details Retrieves the full text and metadata for an already processed, specific transcript. ### list_castmagic_recordings Shows a list of all audio or video files you have uploaded to your Castmagic account. ### list_transcript_speakers Lists every identified speaker within a transcript, helping you manage and track metadata for those voices. ### list_transcripts Provides a list of all transcripts currently saved in your workspace. ## Prompt Examples **Prompt:** ``` Transcribe this audio file: https://example.com/episode1.mp3 ``` **Response:** ``` Submitting 'episode1.mp3' for transcription...

Instead of spending three hours manually summarizing it for Instagram, they submit the URL and use `get_magic_content`. The agent returns five tailored social posts, a blog draft, and full show notes in minutes. ### The agency needs to clean up data An agency project manager has completed multiple client recordings. They need to audit everything before billing. They use `list_transcripts` first, then run `list_castmagic_recordings` to ensure no source media was missed. ### The marketer needs accurate reporting A marketing team records a panel discussion with five experts. They need to know who said what for follow-up actions. They process the video, then use `list_transcript_speakers` to get a detailed list of every participant. ### The creator needs cleanup A content creator keeps old drafts and test transcripts cluttering their workspace. Instead of manually deleting them in the UI, they simply send a prompt asking the agent to run `delete_transcript` for specific IDs. ## Benefits - Saves time on content drafting. Instead of manually writing show notes, use the `get_magic_content` tool to generate polished marketing summaries directly from a transcript ID. - Keeps your workflow clean and organized. Use `list_castmagic_recordings` to see every piece of media you've processed, giving you a centralized content audit trail. - Ensures compliance by tracking usage. The `get_castmagic_account` tool lets you monitor your quota so you never get stuck mid-project due to overages. - Builds reliable data structures. By running the transcript through the speaker analysis tools, you don't just get text; you get metadata identifying who said what. - Maximizes output from minimal input. You only need one URL and a few agent prompts to generate transcripts, show notes, and social posts—all in one flow. ## How It Works The bottom line is: your agent handles the entire content pipeline—from raw media input to final, ready-to-use text output. 1. First, subscribe to the MCP and input your Castmagic Secret Key into your agent. 2. Next, send a command with the URL of the video or audio file you want processed. 3. Finally, wait for the job confirmation; once complete, ask the agent to generate specific assets, like show notes or social posts. ## Frequently Asked Questions **How do I start the process using create_new_transcript?** You send this MCP a direct URL to an audio or video file, and it starts transcribing. The agent will give you a job ID and let you know when the transcript is ready for use. **Can I get show notes without writing them manually using get_magic_content?** Yes. Once `create_new_transcript` finishes, running `get_magic_content` provides AI-driven assets like show notes and social posts based on the transcript's text. **What if I need to track who said what in the recording?
