Real-World Use Cases
The Podcast Launch Kit
A podcaster finishes a 45-minute episode. They prompt their agent: 'Transcribe this audio file: [URL]'. The agent runs create_new_transcript. Once done, they ask the agent to use get_magic_content with the new transcript ID. They instantly get show notes, 5 social posts, and 3 suggested titles, ready to paste into their launch emails.
Webinar to Blog Post Workflow
A content marketer records a 60-minute webinar. They first run create_new_transcript. Then, they use get_transcript_details to pull the raw text. Finally, they feed that text into their agent to structure it into a multi-section blog post, ensuring no manual transcription errors.
Client Content Audit
An agency needs to audit a client's video library. They use list_castmagic_recordings to see all video links. Then, they run list_transcripts to check which ones have been transcribed, letting them know exactly what content is ready for repurposing.
Refining Metadata
The team wants to know who spoke during a key segment of an interview. They first get the transcript ID, then they run list_transcript_speakers to list every person identified in the recording. This allows them to tag the metadata accurately before publishing.
The Tradeoffs
Assuming transcripts are always available
Asking the agent to generate show notes immediately after uploading a video, without checking the status. The agent fails because the transcript hasn't finished processing.
→
First, use create_new_transcript to submit the URL. Wait for the processing job to complete (check the status using get_transcript_details if necessary). Only then should you call get_magic_content.
Copying text manually
Downloading a transcript and then copying the text into a word processor to manually summarize it and create social posts. This takes hours and misses context.
→
Use get_magic_content with the transcript ID. The server generates the summarized text, social posts, and titles automatically. You just copy the final output.
Losing track of content
Starting to transcribe content but forgetting the original recording URL or transcript ID, leading to confusion about what content was processed.
→
Keep a record of your content list. Run list_castmagic_recordings to see all uploaded sources, and use list_transcripts to track all derived transcript IDs.
When It Fits, When It Doesn't
Use this server if your primary bottleneck is turning finished, long-form media (podcasts, videos, webinars) into diverse, usable marketing assets (blog posts, social media captions, show notes). You need the ability to process content via simple URLs and then programmatically generate structured text outputs.
Don't use this if you just need basic file storage or simple text manipulation. If you only need to rename files or move data between two systems, use a general file transfer or cloud storage API instead. If you need to analyze the meaning of the content in relation to an external knowledge base (like documents uploaded to a vector store), you need a different type of RAG (Retrieval-Augmented Generation) tool.
This server is for content transformation and repurposing. Use get_magic_content when you need structured marketing copy; use get_transcript_details when you need the raw, verbatim text.

Works with Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This server provides 8 capabilities that interface natively with Claude, ChatGPT, Cursor, and any MCP client. No middleware. No custom integration required.
Available Capabilities
Turning video files into blog posts shouldn't require a content manager's entire day.
Today, turning a 45-minute podcast into a dozen assets is a manual nightmare. You download the video, transcribe it in one place, then copy the text into Notion for show notes. Next, you copy sections into Buffer for LinkedIn, and then you have to write the intro and conclusion for a blog post manually. It's a mess of tabs, copy-pasting, and lost context.
With the Castmagic MCP Server, you send the video URL to your agent. The agent handles the entire pipeline: it transcribes the audio, then it uses the transcript ID to run `get_magic_content`. You get the show notes, the social posts, and the article draft—all generated and ready in a single response. It's pure automation.
Castmagic MCP Server: Generate content assets from media.
The biggest time sink is the handoff between steps. You have to wait for the transcription to finish, then you have to grab the resulting transcript ID, and then you have to feed that ID into a second tool to get the derived content. This multi-step process is clunky and easy to mess up.
Now, the process is cleaner. You start the job, you get the ID. When you're ready for the copy, you just call `get_magic_content` with that ID. It's a direct, predictable flow that moves you from raw audio to polished assets in two simple steps. The manual orchestration is gone.
Common Questions About Castmagic MCP
How do I use the `create_new_transcript` tool? +
You call create_new_transcript and pass it the URL of the audio or video. The server starts the job and returns a job ID. You then use this ID to check when the transcript is ready.
What does `get_magic_content` actually provide? +
get_magic_content takes a transcript ID and returns several AI-generated assets: show notes, social media posts, and suggested titles. It doesn't give you the raw transcript text.
Can I see all my recordings in Castmagic using `list_castmagic_recordings`? +
Yes. list_castmagic_recordings provides a list of all source URLs that have been uploaded to the Castmagic system, letting you see your content library at a glance.
Is `get_transcript_details` the same as `get_magic_content`? +
No. get_transcript_details gives you the raw, verbatim text of the recording. get_magic_content gives you the AI-written marketing copy derived from that text.
How do I delete old transcripts using `delete_transcript`? +
Call delete_transcript and provide the transcript ID. This removes the transcript and all associated data from your workspace.
How do I check my usage limits using the `get_castmagic_account` tool? +
Use get_castmagic_account to pull your core account data and quota information. This tells you exactly how much usage you have left and when your current subscription period ends.
Can I list the identified speakers in a transcript using `list_transcript_speakers`? +
Yes, list_transcript_speakers pulls a list of every speaker identified in a given transcript. This lets you refine the transcript metadata for better organization.
What is the difference between `list_transcripts` and `list_castmagic_recordings`? +
They track different things. list_castmagic_recordings shows all uploaded audio and video files, while list_transcripts lists the resulting text transcripts.
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? +
Use the list_transcripts tool. Your agent will return a list of all jobs and their current status (e.g., Processing, Finished).
Which languages does Castmagic support? +
Castmagic supports over 18 languages including English, Spanish, French, German, and Portuguese. You can specify the language when creating a new transcript.
