Key Takeaways
- Windsurf MCP SMS is the same REST wrapper loaded in another IDE — not a first-party Windsurf, Cursor, or Claude plugin.
- Example prompt: allowlist tools, pin MCP config, list_devices before send, no OTP in chat.
- Retest after Windsurf/MCP client updates. Schema drift is a send incident.
- No MCP server implementation dump. Live fields live in Developer Center.
- Rate limits still mean OEM + plan caps, not filter evasion.
- You bring the Android and operator credit. We meter devices and send volume.
Windsurf is a host, not a plugin SKU
Windsurf MCP SMS — example agent prompt is host-specific allowlisting for the same Android SMS gateway REST wrapper. Do not rewrite the MCP overview. Spec: MCP specification.
Enabling SMS tools in Windsurf is a config change, not a new SMS network.
Example agent prompt
“You are in Windsurf. Only use SMS tools on the allowlist. list_devices before send. Honor 429. Never dump keys from mcp.json. Never treat this host as a first-party SMS plugin.” Fields: Developer Center.
Host checklist
| Item | Windsurf-specific? | SMS-specific? |
|---|---|---|
| MCP config / allowlist | Yes — this IDE’s files | Which tools can send |
| Gateway REST | No | Same API as Cursor/Claude hosts |
| Paired Android | No | Device setup |
| Client version pin | Yes | Streamable HTTP drift |
Allowlist like any other IDE
Disable bulk send tools in developer IDEs unless a human is in the loop. OTP tools follow the send/verify prompt. Multi-tenant keys still apply if more than one customer shares a machine.
Cost
You bring the Android and operator SMS credit. IDE convenience does not include airtime. Free: 1 device / 300 SMS lifetime / 300 contacts. See device and SMS volume pricing.
Checklist
- No “official Windsurf plugin” claim.
- Allowlist documented for this host.
- Retest after IDE updates.
- list_devices before send.
- OTP isolated; no digits in chat.
- 429 honored.
- No MCP source dump.
- Developer Center for live fields.
Next steps
Transport: Streamable HTTP prompt. n8n is a different automation host — not an IDE.
