Sendmux is an email inbox API and email API for AI agents.

Overview
> Connect AI tools to Sendmux documentation and product tools. Sendmux has two MCP connections. Use Doc Search MCP when you want an AI tool to search Sendmux docs. Use MCP when you want an agent to work with Sendmux tools you authorise. > Info > > MCP exposes a curated agent toolset, not every API endpoint. Use the > SDKs, CLI, or API reference when you need full endpoint coverage. MCP exposes the product surfaces you grant. Hosted MCP is the default when your client supports remote MCP with browser OAuth. It keeps Sendmux in the authorisation flow, avoids distributing manual API keys to agents, and shows only the tools allowed by the grant.
