Read texts, contacts, campaigns and opt-outs; send SMS, add contacts and notes in TextUs. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the TextUs connector, then ask in plain words. The AI picks the tools.
For teams that text customers, leads or clients from a TextUs inbox.
List the unread conversations of an account, newest first. Open the timeline of each one and ask the assistant for a short summary of what the contact wants.
Search the contacts by name or phone number. Read the contact data and the message history with that person before you call back.
List the campaigns of an account and open one to see its message, schedule and recipient counts. Then read the delivery statistics for all campaigns.
List the numbers that opted out of messages, or search for one number. Use the list to remove those people from a planned group message.
Create a contact from the details of a new lead. Then add an internal note with the context, so the next agent sees it. The contact does not see the note.
Changes dataThe login page asks for your TextUs API token.
In TextUs open your user icon → Profile → Advanced user settings → API Tokens, then click Create Token. A token has the same access as your user and can send real text messages. Delete the token in TextUs at any time to revoke access.
Team and Enterprise: an Owner adds the connector for the organization first.
No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"textus": {
"url": "https://textus.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"textus": {
"type": "http",
"url": "https://textus.usefulapi.io/mcp"
}
}
} Run these commands. The second one opens the login page:
Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.
Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your TextUs API token. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Pro | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+ | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this TextUs server only. Ask your AI to run textus_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with textus_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with textus_upgrade before then undoes the cancel. Or write to [email protected].

No. usefulapi is an independent service. It is not affiliated with or endorsed by TextUs. The server calls the TextUs API with your own TextUs access, so it sees only the data that your account can see.
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
The login page asks for your TextUs API token. See Before you connect for where to find it.
No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your TextUs API token. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the TextUs API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in TextUs.
Yes, if you approve it. 3 of the 24 TextUs tools can create or change data. The other 21 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this TextUs server only. Cancel any time: your paid plan then runs to the end of the paid period. Run textus_usage_status to see how many calls you used.
Ask the AI to run textus_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run textus_cancel_subscription. Your paid plan continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with textus_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
