How to Use the Matrix/Element MCP in Windsurf

Q: How do I connect the Matrix/Element MCP Server to Windsurf?

Edit your /.codeium/windsurf/mcpconfig.json file and add the server configuration under the mcpServers key. Cascade automatically discovers the 19 tools upon restarting the editor.

Q: Can Windsurf Cascade handle secure Matrix/Element logins?

Yes. Cascade uses loginaccount to establish the initial session and logoutaccount to destroy it when done. Your credentials remain safe inside the secure Vinkius sandbox environment.

Q: How does Windsurf manage background Matrix/Element syncs?

Cascade calls syncclient to pull the latest room states and timelines. This ensures your editor stays updated with live room events without manual polling.

Q: What happens if a user requests access to a Matrix/Element room in Windsurf?

Cascade processes requests by calling knockroom or joinroom based on the room's access rules. It uses the MCP connection to read the current room state using getroomstate before attempting to enter.

Run multi-step Matrix/Element communication chains autonomously using Windsurf and Cascade.

Automate Room Operations with Windsurf Cascade

The `create_room` tool lets Windsurf build new channels instantly. Cascade reads your context, decides when a new space is required, and spins it up via the MCP Server without waiting for your permission. Once the room exists, Cascade uses `set_room_state` to configure permissions and `join_room` to bring in the team. You set the goal of organizing an incident response, and your editor does the rest.

Secure End-to-End Key Management

The `upload_keys` tool handles cryptographic identity verification. Windsurf manages your secure sessions by pushing your local pre-key bundles directly to your homeserver. When you need to read encrypted threads, Cascade chains `claim_keys` and `query_keys` to decrypt payloads. You don't copy keys manually; the editor resolves the cryptographic handshakes in the background.

Manage Live Message and Media Flows

The `send_message` tool delivers automated alerts directly to your team rooms. Cascade uses the MCP integration to monitor your files, detect build failures, and post status updates with zero manual prompts. If you need to share assets, Cascade calls `upload_media` to push local build logs or screenshots. It pulls incoming assets with `download_media` when your team replies with feedback.

Setup guide

Set up Matrix/Element 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.

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 Matrix/Element payment history." If connected, Cascade will call the Matrix/Element tools directly. You will see a green dot next to the server name in the MCP panel.
