How to Use the Ably MCP in Cursor

Q: How does Cursor use Ably to generate accurate code?

Cursor pulls live message schemas using getmessages. This lets the agent write precise typescript interfaces based on real payloads instead of outdated documentation.

Q: Can I test Ably push notifications directly inside Cursor?

Yes, you can ask the agent to run pushpublish to send test payloads. It verifies the delivery status directly in the terminal chat.

Q: How do I inspect active Ably channels within Cursor using this MCP Server?

The agent runs listchannels to find active streams and outputs their metadata. You can inspect active connections without opening an external browser tab.

Q: What happens when I need to revoke client tokens?

The agent calls revoketokens to instantly invalidate credentials on your account. This helps you test connection failure states and error handling in your local code.

Write code in Cursor using live Ably payloads

This MCP Server feeds real-time production payloads directly into Cursor's Composer. Your agent calls `get_messages` to pull actual message histories, letting you write parsers against real JSON structures instead of guessing with mock data. Instead of switching back and forth between your editor and the browser, the agent uses `get_channel_metadata` to check active configurations. You write your subscription code using the exact fields currently live on your network.

Inject real presence states into Cursor

Cursor uses this MCP Server to pull live user states directly into your workspace. It triggers `get_presence` and `batch_presence` to see who is connected to your dev channels right now. The agent analyzes this data to generate matching TypeScript interfaces or React hooks. It uses `get_presence_history` to understand the lifecycle of your connection events and write cleaner state management code.

Verify messaging logic inside your editor

Test your publish-subscribe pipelines without leaving your code files. Your agent triggers `publish_message` or `batch_publish` to fire test payloads down your channels, verifying your local listeners react correctly. For push notification setups, the agent calls `push_publish` or `batch_push_publish` to send test alerts to your devices. You can verify your payload schemas instantly while the agent monitors the output.

Setup guide

Set up Ably MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Ably MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Ably transactions." If the MCP tools are loaded correctly, Cursor will call the Ably tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "ably-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
}
