Perplexity

Automate message consumption inside Windsurf

The `pull_messages` tool connects Cascade directly to your Google Cloud queue to ingest payloads without leaving your editor. This MCP Server lets your agent monitor incoming tasks, inspect message schemas, and plan backend updates based on real-time event data. Cascade reads the schema of the pulled messages, writes the necessary processing logic, and executes the code. You get an autonomous queue worker that writes its own handlers on the fly.

Commit processed events instantly

The `acknowledge_messages` tool prevents message redelivery by letting Cascade confirm successful processing directly to Google Cloud. Your agent tracks which payloads it successfully ran through your local codebase and commits the status immediately. If a handler fails during a Cascade test run, the message remains in the queue. This setup gives you a safe playground to debug subscription consumers without losing production events.

Build self-healing pipeline workers

The `pull_messages` tool initiates a feed of event payloads that Cascade uses to diagnose system failures. When an error payload arrives, Cascade analyzes the stack trace, modifies your local code, and runs tests to verify the fix. Once the test suite passes, Cascade invokes `acknowledge_messages` to clear the queue. You watch the entire debugging loop happen in your Windsurf panel without touching a terminal.

Setup guide

Set up Google Pub/Sub Subscription MCP in Windsurf

Prerequisites

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

1

Open MCP configuration

Click the Cascade assistant icon in the sidebar, then click the hammer icon (🔨) at the top of the panel. Select "Configure" to open ~/.codeium/windsurf/mcp_config.json.
2

Add the Google Pub/Sub Subscription MCP

Paste the JSON snippet shown on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Refresh MCPs

Go back to the hammer icon (🔨) in Cascade and click "Refresh". Windsurf will detect the new server. No full restart is needed — the connection is hot-reloaded.
4

Verify in Cascade

Start a new Cascade conversation and ask something like "Show my Google Pub/Sub Subscription payment history." If connected, Cascade will call the Google Pub/Sub Subscription tools directly. You will see a green dot next to the server name in the MCP panel.

Common questions about Google Pub/Sub Subscription MCP in Windsurf

Open your Windsurf settings and add the server to your configuration file. Cascade instantly detects the pulling and acknowledging tools, making them available for your active coding sessions.

Yes, Cascade chains the pulling and acknowledging tools to process batches sequentially. It reads the messages, writes the processing code, and then triggers the acknowledgment to keep your queue moving.

If Cascade crashes before calling the acknowledgment tool, Google Cloud redelivers the message. This prevents data loss and lets you retry the processing step once you resolve the code issue.

No, Cascade uses the built-in tools to fetch payloads directly. You simply tell Cascade what to do with the incoming data, and it handles the API calls.

Your message payloads and ackIds remain strictly inside your local Windsurf environment. Vinkius runs the server in an isolated sandbox, meaning your sensitive queue data never touches external logs or third-party servers.
