TextKit is an SMS platform for developers and AI agents that lets you send and receive texts in the US and Canada through a simple API, CLI or MCP server.
You can get a number, send a message and handle replies in minutes, and test everything first in a sandbox that simulates delivery, spam filtering, opt-outs and rate limits without sending real texts.
Through its MCP server, AI agents in Claude, ChatGPT, Cursor or your own app can buy numbers, send messages, manage contacts and debug delivery issues. TextKit also provides skills and an llms.txt file describing the product for language models.
Key features include two-way SMS with webhooks, phone numbers in more than 200 US and Canada area codes, one-time code verification billed on success, shared inboxes with roles, broadcasts with merge fields and scheduling, automations triggered by app events, and automatic STOP, START and HELP handling.
It also offers message logs, delivery tracking, carrier lookups, clear error messages, SMS analytics and usage and billing views. A2P 10DLC registration is filed for you.
SDKs and examples are available for Node.js, TypeScript, Python, Ruby, Go and cURL, with integrations for Claude, Claude Code, Cursor and Copilot.
Pricing: a free Developer plan with up to 100 texts a month, then paid plans from 49 US dollars a month, all plus 0.002 US dollars per text and carrier fees at cost. Failed sends cost nothing.
It is suited to developers adding login codes, reminders, alerts, shipping updates or marketing texts to their products.
