Sendmux SDKs
The official monorepo of client libraries, a command-line tool and MCP servers for the Sendmux email API, covering sending, mailbox and account-management endpoints across TypeScript, Python, Go, PHP, Rust and Ruby.
Sendmux SDKs is the official workspace of software development kits, a CLI and Model Context Protocol servers for Sendmux, an email API platform. Packages are published per language and per API surface: shared core helpers, a sending-API client, a mailbox-API client for reading and managing inboxes, and a management-API client for account-level operations, each available for TypeScript and Python, with additional language SDKs noted for Go, PHP, Rust and Ruby.
A command-line tool and a Homebrew tap install the sendmux CLI directly, and a Vercel AI SDK integration and a LangChain toolkit expose the sending and mailbox APIs as tools for AI agents. An MCP package provides both a local server and hosted MCP and agent-to-agent servers, authenticated with OAuth for the hosted service or with API keys scoped to a specific surface for local use.
