How to Connect Claude, Cursor, and ChatGPT to Slack, Stripe, Notion, and HubSpot

You want to connect Claude to Slack. Or Cursor to Stripe. Or ChatGPT to your HubSpot CRM. You’ve Googled it. You’ve found tutorials telling you to edit JSON config files, generate API keys, install npm packages, and set environment variables.

There’s a faster way. Every connection below takes under 5 minutes. No code. No terminal. No API key management.

How Every Connection Works (Same 3 Steps)

No matter which AI tool or business app you’re connecting, the process is identical:

Step 1. Go to our App Catalog and subscribe to the app you need.

Step 2. Copy the connection URL we generate for you.

Step 3. Paste it into your AI tool’s MCP settings.

That’s it. Now let’s do it for each specific combination.

Connect Claude Desktop to Your Apps

Claude → Slack

What you’ll be able to do:

• “Summarize the last 20 messages in #sales”
• “Post a message to #marketing: Q1 report is ready”
• “What did the team discuss in #product yesterday?”

Setup:

1. Subscribe to Slack MCP in our catalog
2. Copy your connection URL
3. In Claude Desktop: Settings → Developer → Edit Config
4. Add to your mcpServers:

{
  "mcpServers": {
    "slack": {
      "url": "https://edge.vinkius.com/YOUR_TOKEN/slack-mcp"
    }
  }
}

5. Restart Claude. Done.

The DIY alternative (what you’re skipping): Create a Slack app in api.slack.com, generate a Bot Token, install @modelcontextprotocol/server-slack via npx, configure environment variables, manage token rotation manually. ~45 minutes + ongoing maintenance.

Claude → Stripe

What you’ll be able to do:

• “What’s our MRR this month?”
• “List all failed payments from the last 7 days”
• “How many new subscriptions this week vs. last?”

Setup:

1. Subscribe to Stripe MCP in our catalog
2. Copy your connection URL
3. Add to Claude’s config:

{
  "mcpServers": {
    "stripe": {
      "url": "https://edge.vinkius.com/YOUR_TOKEN/stripe-mcp"
    }
  }
}

4. Restart Claude. Done.

The DIY alternative: Generate a Stripe Restricted API Key, figure out which permissions to enable (there are 40+), store it in a .env file, install the Stripe MCP server, hope your key doesn’t expire. ~60 minutes + security risk of plaintext keys.

Claude → Notion

What you’ll be able to do:

• “Find the product requirements doc and summarize it”
• “What tasks are marked ‘In Progress’ in our project tracker?”
• “Add a new page to the Engineering wiki with this content”

1. Subscribe to Notion MCP in our catalog
2. Copy your connection URL
3. Add to Claude’s config:

{
  "mcpServers": {
    "notion": {
      "url": "https://edge.vinkius.com/YOUR_TOKEN/notion-mcp"
    }
  }
}

4. Restart Claude. Done.

Claude → HubSpot

Setup: Subscribe to Google Sheets MCP → copy URL → add to config → restart.

The Complete Connection Matrix

Here’s every combination at a glance. Every cell works the same way: subscribe → copy URL → paste.

Why This Is Easier Than the DIY Approach

Every connection you just saw requires 3 things the traditional way:

1. An API key from the business app (Stripe dashboard → API keys → create restricted key → select 40+ permissions)
2. An MCP server installed on your machine (npm install, npx, Node.js version management)
3. A config file with sensitive credentials stored in plaintext on your disk

With us, you skip all three:

• No API keys in your config — We store them in an encrypted vault
• No server to install — We host it for you, always running, always updated
• No plaintext credentials — Your config only contains a URL, not secrets

Plus, every connection includes features the DIY approach doesn’t have:

• Automatic DLP — Credit cards, SSNs, and API keys are redacted before reaching your AI
• Audit trail — Every request your AI makes is logged
• Kill switch — Disable any connection instantly with one click
• FinOps controls — Set request limits to prevent runaway costs

Start Connecting

Step 1. Create a free account.

Step 2. Browse the App Catalog — over 2,500 apps available.

Step 3. Subscribe to your first app. Copy the URL. Paste it into your AI tool.

Step 4. Ask your AI something real.

Your first connection takes 3 minutes. Every additional one takes 30 seconds.
