How to Use the Amazon S3 Bucket MCP in Windsurf

Q: How do I connect the Amazon S3 Bucket MCP Server to Windsurf?

Edit your /.codeium/windsurf/mcpconfig.json file or open the Settings UI. Add the Vinkius endpoint under the mcpServers section. Hit refresh in the MCP panel and Cascade will auto-discover the tools.

Q: Does the Amazon S3 Bucket MCP Server let Windsurf delete files?

It does. The agent can call deleteobject when you ask it to remove specific files. Cascade will usually run a list command first to confirm the target.

Give Cascade direct read and write access to a single S3 bucket from within Windsurf.

Perplexity

Autonomous object management via MCP Server

Cascade handles your remote files without asking for permission at every step. You tell it to back up a local directory, and it figures out the rest. It runs `list_objects` to check what is already there, then fires off `put_object` to upload the missing pieces. You do not have to write boilerplate AWS SDK code just to move files around. The agent chains these operations in the background. If you need to clear out old logs, Cascade maps the prefix and executes `delete_object` on the matches.

Inspect bucket security instantly

Figuring out why a file is throwing a 403 usually means digging through the AWS console. Now your IDE does that for you. Windsurf pulls the exact rules controlling your data using `get_bucket_policy`. Cascade reads the JSON response directly and spots the missing permissions. It can also run `get_bucket_acl` to see exactly who owns the bucket and what access they have. You get the answer right in your editor.

Read and write file content directly

Sometimes you just need to know what a remote config file actually says. Cascade grabs the raw text using `get_object_data` and drops it into your context window. No downloading required. When you finish editing that config locally, the agent pushes the updated version back to AWS. It checks `get_object_metadata` first to ensure it is not overwriting a newer file. The entire cycle happens right where you write code.

Setup guide

Set up Amazon S3 Bucket 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 Amazon S3 Bucket 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 Amazon S3 Bucket payment history." If connected, Cascade will call the Amazon S3 Bucket tools directly. You will see a green dot next to the server name in the MCP panel.

Yes, it reads them directly into your context. Cascade uses the get_object_data tool to fetch file contents. This works perfectly for JSON configs, text logs, and code snippets.

It does. The agent can call delete_object when you ask it to remove specific files. Cascade will usually run a list command first to confirm the target.

Cascade pulls the raw access rules straight from AWS. It runs get_bucket_policy and get_bucket_acl to show you exactly how the bucket is secured. You never have to leave the editor to debug an access error.

Vinkius runs your connection in an ephemeral V8 Isolate Sandbox. When Cascade fetches file contents or bucket policies, that data stays in memory just long enough to process the request. Nothing gets stored permanently on our infrastructure.
