What is API, MCP, OpenClaw, and all this talk?
Connecting CRUSH to Other Apps
You know how CRUSH records your voice and turns it into text? Now you can send that text and audio to other apps automatically. Here's how it all works, in plain English.
What Are These New Features?
CRUSH now has three ways to connect with other tools:
| API Key | A password for apps to access your CRUSH data |
| Webhooks | Automatic delivery of new recordings to other apps |
| MCP | A way for AI assistants to read your CRUSH notes |
Think of it this way:
- API Key is like giving a trusted friend a key to your filing cabinet so they can look through your notes whenever they want
- Webhooks are like having a copy machine that automatically sends a copy of every new note to someone's desk the moment it's ready
- MCP is like having a research assistant who can search through all your notes and answer questions about them
API Key - Let Apps Access Your Notes
What is an API key?
An API key is a special password that lets other software read your CRUSH notes. It's a long string of characters that looks like this: crush_sk_a1b2c3d4...
When you give this key to another app, that app can pull your notes, transcripts, and audio recordings from CRUSH - just like you'd log in and read them yourself, except the app does it automatically.
What can apps do with your API key?
- Read all your notes and transcripts
- Download your audio recordings
- See your folders and tags
- Check your account and credit balance
What does it cost?
Reading your notes, downloading audio, and browsing folders is free - it doesn't use any of your AI credits. The only activity that costs credits is if an app triggers AI features like generating insights.
Keeping your key safe
Your API key is like a password. Anyone who has it can read your notes. If you think someone got access to your key who shouldn't have, go to Account > API Key > Regenerate and the old key will stop working immediately.
Webhooks - Get Notified When New Notes Are Ready
What is a webhook?
A webhook is an automatic delivery system. Every time you record something on your CRUSH device and it finishes transcribing, CRUSH sends the finished transcript to another app - automatically, without you doing anything.
Think of it like email forwarding. You set it up once, and from then on, every new recording gets sent to wherever you want it to go.
What gets sent?
When a recording finishes transcribing, CRUSH sends:
- The full transcript (with speaker labels if multiple people were talking)
- A link to download the audio file (valid for 1 hour)
- The date and time of the recording
- The note ID (so apps can reference it later)
What can you do with this?
Here are some real examples:
- Automatically save meeting notes to Google Docs - Every recording becomes a document
- Send transcripts to Slack - Your team sees notes as soon as they're ready
- Build a searchable archive - Send everything to Notion, Airtable, or a spreadsheet
- Feed recordings into your own app - If you're a developer, receive the data at your own server
MCP - Let AI Assistants Read Your Notes
What is MCP?
MCP stands for Model Context Protocol. It's a new standard that lets AI assistants (like Claude, Cursor, and others) connect directly to apps like CRUSH.
Without MCP, if you wanted an AI to help you with your meeting notes, you'd have to copy and paste the text into the AI chat window. With MCP, the AI can search through your CRUSH notes directly and pull up whatever it needs.
What can AI assistants do with your CRUSH notes?
Once connected, you can ask your AI assistant something like:
- "What did I record yesterday?"
- "Search my notes for anything about the product launch"
- "Summarize my meetings from this week"
- "Find the recording where we discussed the budget"
- "How many AI credits do I have left?"
The AI will search your CRUSH notes, read the transcripts, and give you answers - all without you having to leave the AI tool or dig through notes yourself.
Which AI tools support MCP?
MCP is supported by a growing list of tools including:
- Claude (desktop app and Claude Code)
- Cursor (code editor with AI)
- Windsurf (code editor with AI)
- And more being added regularly
Quick Comparison
| Feature | What it Does | For Whom | Setup Time |
| API Key | Lets apps read your notes on demand | Developers building integrations | 2 minutes |
| Webhooks | Automatically sends new recordings to other apps | Anyone who wants automatic delivery | 5 minutes |
| MCP | Lets AI assistants search and read your notes | Anyone using AI tools like Claude | 3 minutes |
FAQs
Do I need all three?
No. Pick whichever one fits what you're trying to do. Most people start with either webhooks (if they want automatic delivery) or MCP (if they use AI assistants).
Does this cost extra?
No. These features are included with your CRUSH subscription. Reading notes and downloading audio doesn't use any AI credits.
Can other people see my notes?
Only if you give them your API key. Your key is private to you, so don't share it with anyone you don't trust.
What if I lose my API key?
Go to Account > API Key > Regenerate. This creates a new key and the old one stops working.
Do I need to be technical to use this?
For webhooks and MCP, no as they're designed for everyone. The REST API is more for developers who are building custom software.
