The AI code editor

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

Add TextKit 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

Texts, numbers, verification, contacts, broadcasts and automations become tool calls. One click, or add this to Cursor's mcp.json. Cursor asks you to sign in to TextKit the first time.

Add to Cursor

{
  "mcpServers": {
    "textkit": { "url": "https://mcp.jointextkit.com" }
  }
}

Every tool and how sign-in works: MCP server docs

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://jointextkit.com/skills/install.sh | sh

textkit · textkit-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 TextKit Verify
(POST /v1/verify, then /v1/verify/check). Docs:
https://jointextkit.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.
