Add HeyOnCall MCP Server

[compumike]

Adds the HeyOnCall MCP server to the "Official Integrations" section of README.md.

Description

The HeyOnCall MCP Server allows you to just add something like: Page me when you're done. to your prompts and your agent will be able to send notifications to our free iOS or Android apps:

The HeyOnCall MCP Server exposes a single tool HeyOnCall__set_alerting which allows the agent to set a trigger to alerting, optionally passing a short message as well.

It's free, and our iOS and Android apps are free as well.

Motivation and Context

As tools like Claude Code can run longer without supervision, this MCP server allows you to get notified when a task list is done (or other criteria of your liking, simply by prompting), so you're not chained to your desk.

How Has This Been Tested?

The HeyOnCall MCP server has been tested with Claude Code, Cursor, and RubyLLM::MCP. The RubyLLM::MCP tests are part of our CI test suite. Our CI test suite also includes several custom request tests for the MCP server.
