How to Use the iFax MCP in Windsurf

Q: How do I add the iFax MCP Server to Windsurf?

Open your /.codeium/windsurf/mcpconfig.json file and add the server configuration under the mcpServers key. You can also use the Settings UI under Cascade to paste the endpoint token and refresh the panel.

Q: Can Cascade chain iFax tools in Windsurf autonomously?

Yes, Cascade reads your prompt, calls sendfax, and automatically polls getfaxstatus until delivery succeeds. It manages the entire sequence without requiring separate prompts for each step.

Q: How does Windsurf handle failed transmissions with iFax?

Cascade detects the failure from the getfaxstatus payload and immediately decides whether to trigger resendfax or cancel the job. It uses the toolset to resolve delivery issues on the fly.

Q: Where does this integration store downloaded documents?

The downloadfax tool saves incoming PDF files directly to the workspace path specified by Cascade. You control the target directory through your natural language instructions.

Q: Is my fax data secure when using iFax in Windsurf?

All base64 payloads and PDF metadata processed by sendfax run through a sandboxed V8 isolate. Your document content remains encrypted in transit and never touches external caching servers.

Send and track secure faxes directly from Windsurf using Cascade's autonomous multi-step execution.

Autonomous Fax Workflows in Windsurf

The `send_fax` tool lets Cascade transmit documents as base64-encoded strings without manual intervention. You give Cascade a PDF, and it converts the file, packages the metadata, and sends the payload to the iFax API in one go. If a transmission fails, Cascade doesn't stop to ask you what to do next. It automatically triggers `resend_fax` or checks the queue, handling errors on its own so you don't have to babysit the process.

Real-Time Status Tracking with this MCP Server

The `get_fax_status` tool queries the live delivery state of any sent document. Windsurf reads this status to determine if a transmission succeeded, failed, or is still pending in the telecom queue. For failing transmissions, Cascade uses `cancel_fax` to stop stuck jobs before they waste your API credits. It then pulls your history with `list_faxes` to check that the queue is clean before attempting another run.

Local Document Management

The `download_fax` tool pulls incoming documents directly into your Windsurf workspace via the MCP connection. Cascade identifies incoming faxes, downloads the files, and organizes them into your local directory structure automatically. This removes the need to log into a web portal to grab your files. Your autonomous agent handles the retrieval, updates your local index, and notifies you when the document is ready to read.
