The old way means hours in transcript tabs and copy/paste hell.
Right now, if you record a podcast, the manual process looks like this: You download the audio file. You upload it to a transcription service—one tab. Then, you manually read through the resulting text, searching for key quotes and moments that need separate posts. You copy those quotes into a second tool or document. Finally, you write the show notes based on what's left over.
This MCP changes the game. You just send the URL to your agent. The system handles all the tabs in the background: transcription, speaker identification, asset generation—all automatically. What you get is a single, complete package of usable text ready for publication.
Get Magic Content with `get_magic_content`
The most time-consuming part used to be writing the show notes and social posts. You'd transcribe the episode, then you’d have to manually summarize it into a blog post draft, write separate captions for LinkedIn, and create three different teaser quotes.
Now, after creating the transcript using `create_new_transcript`, you simply point your agent at that specific transcript ID and call `get_magic_content`. You get structured show notes, multiple social drafts, and suggested titles—all based on the actual content. It’s a single step.
What your AI can actually do with this
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.
019d756a-8551-72cd-8d2b-473f5a2e81c8 Here's how it actually works
The bottom line is: your agent handles the entire content pipeline—from raw media input to final, ready-to-use text output.
First, subscribe to the MCP and input your Castmagic Secret Key into your agent.
Next, send a command with the URL of the video or audio file you want processed.
Finally, wait for the job confirmation; once complete, ask the agent to generate specific assets, like show notes or social posts.
Who is this actually for?
This connector is essential for anyone who creates high volumes of audio or video but lacks the staff time to manually pull out quotes and create marketing materials. Podcasters, content marketers, and agency media buyers rely on this to maintain a consistent posting schedule without burning out.
They submit their latest episode URL and immediately get ready-to-post show notes and three different versions of social clips.
After recording a webinar, they feed the video into the MCP and pull out multiple blog post drafts and LinkedIn updates instantly.
They process content for several client accounts simultaneously, ensuring rapid transcript delivery across different projects.
What Changes When You Connect
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.
See it in action
The podcaster needs evergreen content
A podcaster finishes an hour-long interview. 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.
The honest tradeoffs
Copy-pasting quotes
A user transcribes an audio file manually and then has to copy key moments into a separate document, losing context or misattributing speakers.
First, use create_new_transcript for the raw media. Then, instead of manual copying, ask your agent to run get_magic_content against that transcript ID to automatically pull out and format key insights.
Using general summarization tools
Relying on a generic LLM prompt with just a raw text dump. The resulting summary is often vague, lacks specific titles, or misses the tone of the original content.
Use this MCP. After getting a transcript via create_new_transcript, run get_magic_content. This tool specifically trains on media context to give you structured show notes and social posts.
Ignoring quota limits
A user starts processing multiple videos back-to-back, hits a usage cap halfway through their campaign, and the entire workflow stalls with an error.
Always check your capacity first. Run get_castmagic_account at the start of any large content push to verify you have enough quota remaining.
When It Fits, When It Doesn't
Use this MCP if your primary bottleneck is taking raw audio or video and turning it into multiple, structured text assets (transcripts, blogs, posts). If you only need basic transcription without marketing fluff, there are simpler tools available. However, if you need to go from 'media' to 'marketing copy,' you need the full suite of tools here. Don't use this MCP if your content is already in a perfectly formatted blog post or research document; those types of inputs don't require media processing. You only use it when the source material is an unedited file, and you need the system to do the heavy lifting of transcribing, analyzing speakers, generating titles, and drafting social posts all at once.
Questions you might have
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? Should I use list_transcript_speakers? +
Yes, use list_transcript_speakers. This tool doesn't just give you a name; it lets you manage and refine metadata for every identified voice in your recorded material.
Do I need to manually delete old transcripts after using delete_transcript? +
No. Calling delete_transcript removes both the transcript and all associated data, cleaning up your workspace completely with one command.
How can I check my usage limits and quota using get_castmagic_account? +
You use get_castmagic_account to pull your current subscription status and remaining credits. This lets you monitor your usage directly, so you never hit an unexpected paywall mid-project.
If I need to see a list of all my past media transcriptions, should I use the list_transcripts tool? +
Yes, running list_transcripts pulls every available audio and video transcription record. This gives you an immediate index of your entire content history within the system.
What does running list_castmagic_recordings actually show me? +
It provides a comprehensive list of every original recording you've uploaded to Castmagic. Use this tool to quickly audit and manage all your source content material.

Just provide the transcript ID to get_transcript_details. You immediately retrieve the full, accurate text content and all associated metadata for that specific file.
Can I generate social media posts from a podcast link? +
Yes! Use the create_new_transcript tool with your podcast audio URL, then use get_magic_content once processing is finished to retrieve AI-generated social posts.
How do I check if my transcription is ready? +
