The ClickSend MCP Server extends ClickSend’s SMS capabilities into modern AI platforms, enabling developers to send SMS messages through ClickSend without writing custom integration code. Built for Node.js (requires Node.js >= 18), the server runs as an MCP endpoint that can be configured via two environment variables: CLICKSEND_USERNAME and CLICKSEND_API_KEY. The README provides two Claude Desktop configuration approaches: using the NPM package (npx @clicksend/clicksend-mcp-server@latest) or a local build that points to build/clicksend-mcp.js, with the env vars supplied in Claude's configuration. A sample Claude Desktop config demonstrates how to register an MCP named 'clicksend' with a command and environment variables. The MCP exposes endpoints such as POST /v3/sms/send, POST /v3/sms/price, GET /v3/sms/templates, GET /v3/sms/history, GET /v3/statistics/sms, and GET /v3/search/contacts-lists. It emphasizes security and best practices (never commit credentials, adhere to rate limits) and includes notes on phone formatting (E.164) and troubleshooting. This server is designed to empower AI workflows and assistants to trigger ClickSend SMS from within AI-driven apps and desktop clients.
