ClickSend provides business messaging services including SMS, MMS, email, voice, fax, post, contacts, and related account/statistics functions. It offers programmatic access to these capabilities through its developer API and an MCP server package for AI-compatible clients.
ClickSend exposes a REST API v3 at `https://rest.clicksend.com/v3` authenticated with HTTP Basic credentials, plus an official npm-distributed MCP server/CLI package configured with `CLICKSEND_USERNAME` and `CLICKSEND_API_KEY`.

Sign up for a ClickSend account via ClickSend Dashboard signup, then open the dashboard's API Credentials area (the docs say it is available from the top right of the dashboard; the MCP guide points to Subaccounts / API credentials). Copy your username and API key. These are used together for HTTP Basic auth, or supplied as CLICKSEND_USERNAME and CLICKSEND_API_KEY for the MCP server.
Create an account from ClickSend Dashboard signup. The OpenAPI description says the REST API also accepts the same username and password you use to log in to the dashboard via HTTP Basic authentication.
