Your AI coding tools shouldn’t need you to copy-paste documentation into every prompt. The Model Context Protocol (MCP) is an open standard that gives AI applications a direct line to external services, so they can pull the information they need on their own. Sendmux has an MCP server that connects AI assistants to our full knowledge base: guides, code examples, and API references. All searchable in real time.

​
Documentation MCP Server

The Sendmux MCP server is hosted by Mintlify. It exposes a search_sendmux tool that lets any connected AI client search across all Sendmux documentation, find implementation details, and pull up API references without you leaving your editor. Server URL: 
https://docs.sendmux.ai/mcp

​
What your AI tools can do

Once connected, AI assistants can:
  • Look up API endpoints, request formats, and error codes
  • Find code examples for sending emails via HTTP or SMTP
  • Answer questions about Sendmux features like batch sending, idempotency, and attachments
  • Pull provider configuration and billing details from the docs
No context window wasted on pasting docs. Your AI tool fetches exactly what it needs.
