📖 Overview
Windsurf (by Codeium) is an agentic IDE that ranks alongside Cursor as one of the most-used AI coding tools in 2026, backed by a multi-year Google Cloud partnership. The Pro plan ($15/month) unlocks premium model credits (GPT-4o, Claude), unlimited AI completions, and the advanced Cascade agent workflow. This tutorial covers subscribing at windsurf.ai with an MPChat Cloud Card.
🔑 Prerequisites
A successful subscription hinges on three elements staying aligned: a compliant service account, a stable US IP, and a funded MPCard.
MPChat account ready
Install the official MPChat app, complete identity verification, and activate the wallet
Issue an Cloud Card (VISA); record the 16-digit card number, expiry and CVC
Network setup
Use a stable US residential IP; avoid public Wi-Fi, datacenter, or shared proxy IPs
Keep IP region consistent with the card and billing address to pass risk checks
Funding ready
Windsurf costs around $15/month; stock ~$22 in USDT to cover the $1 pre-auth and FX
Keep card balance ≥ $17 so the first charge is not blocked

Plan reference
Plan | Price | Best for |
Free | $0/mo (limited model credits) | Light AI coding experience |
Pro | $15/mo (premium models + unlimited completions) | Active developers |
Pro (annual) | $12/mo (billed $144/yr) | Save 20% vs monthly |
Teams | $30/user/mo | Team-level access + admin |
Phase 3 - Payment Details (critical step)
Payment method: choose Credit Card, then click Add Payment Method
Card fields (from MPChat App → MPCard → Card details):
Card Number: 16-digit number
Expiry Date: MM/YY
CVC Code: 3-digit security code
Name on Card: use your real name (Latin letters)Billing address: use a reputable US address generator; ensure the ZIP is valid:
Street: 1234 Maple Street
City: San Francisco
State: CA
ZIP Code: 94102
Country: United States
Verification & activation
Windsurf authorizes a $1 charge as verification (usually refunded immediately)
After payment succeeds the subscription goes Active right away
Sign in, test core features, and confirm the renewal cycle on the Billing page
⚠️ Notes & Troubleshooting
Service-specific notes
Windsurf uses Stripe, similar to Cursor and GitHub Copilot — MPCard has high acceptance rates
The Pro plan includes monthly Flow Credits for premium models; once used up, you can still use free-tier models without service interruption
Windsurf can coexist with VS Code extensions, but for a cleaner AI coding experience, pick one primary AI IDE
After subscribing, check your remaining Flow Credits and renewal date under the Account tab inside the IDE
Common payment failures
Error | Fix | Priority |
Card declined | Verify the three-in-one: US IP + Cloud Card + US billing address | ⭐⭐⭐⭐⭐ |
Address invalid | Regenerate a detailed real US address; ZIP must match State | ⭐⭐⭐⭐ |
IP flagged | Switch to a US residential IP; avoid datacenter or public proxies | ⭐⭐⭐⭐ |
Insufficient balance | Top up MPCard to at least $17 | ⭐⭐⭐ |
Subscription management
Check status: account page → Settings / Billing
Download invoice: receipts available on the Billing page
Upgrade / downgrade: change plan any time
Auto-renew: on by default, charged on the same day each month
Cancel: Settings → Billing → Cancel Subscription. Access continues through the end of the paid cycle.
Security reminders
Card protection: set a monthly spend limit on the MPCard to reduce fraud risk
Account security: enable two-factor authentication (2FA) on the Windsurf account
Network consistency: keep a US IP around renewal dates so the account is not flagged
❓ FAQ
Windsurf vs Cursor — which is better for me?
Both are excellent. The main difference is mode: Cursor suits developers who want fine-grained, line-by-line control. Windsurf's Cascade shines at agentic cross-file task completion — ideal when you're rapidly building new features.
The Free tier is good enough for now. Is Pro worth it?
If you use AI coding more than 2 hours per day, the Free model quota runs out quickly. Pro's key value: unrestricted access to premium models (GPT-4o/Claude) and a larger Cascade context window for longer autonomous tasks.
I already have Cursor Pro. Do I also need Windsurf?
Not necessarily — the two heavily overlap. Dual subscriptions are usually redundant. Use one tool deeply for 2-4 weeks before deciding whether to switch or keep both.

💬 Still having trouble?
Do not retry payments repeatedly in a short window—it triggers risk-control cooldowns. Screenshot the error and click the chat icon at the bottom-right to reach MPChat support for 1-on-1 help.
Don't have an MPCard yet? Apply for an Cloud Card (VISA) in the MPChat App — about 1 minute end-to-end to generate a virtual card.
This guide gets Windsurf subscribed in 10-15 minutes. If anything fails, check the US IP + Cloud Card + US billing address alignment first.
