Use SimpleSMS with Cursor.SMS, phone verification, and real numbers, as capabilities.

Add SimpleSMS to Cursor's MCP config and the agent tab can send test messages and wire verification flows while you watch the diff.

1. Connect the MCP server

SimpleSMS speaks Model Context Protocol. Add this to Cursor's MCP configuration and messages, verification, numbers, and lookup become tool calls:

{
  "mcpServers": {
    "simplesms": {
      "url": "https://mcp.joinsimplesms.com",
      "headers": { "Authorization": "Bearer ssms_sk_test_YOUR_KEY" }
    }
  }
}

Discovery: /.well-known/mcp.json

2. Install the skills

Three SKILL.md files teach Cursor the API, the verification rules, and SMS compliance, so it writes correct integration code the first time:

curl -sSL https://joinsimplesms.com/skills/install.sh | sh

simplesms · simplesms-verify · sms-best-practices

3. Ask for the feature

A prompt like this now resolves against the real API, with a sandbox key that simulates everything and costs nothing:

Add phone verification to signup using SimpleSMS Verify
(POST /v1/verify, then /v1/verify/check). Docs:
https://joinsimplesms.com/docs/verify.md

Everything Cursor needs is machine-readable: an OpenAPI spec, markdown twins of every docs page, and a single-file llms.txt of the whole documentation set.
