Yo — Agent Plugin

Let your agent Yo you: one MCP tool call sends a content-free push notification to your phone. The sender identity plus the moment of the ping is the message.

This package is the public integration for the hosted Yo service (Agent Plugins 1.0.0 format):

  • plugin.json — plugin manifest
  • mcp.json — portable Agent Plugins Streamable HTTP config for the hosted Yo MCP server
  • skills/yo/SKILL.md — teaches your agent when and how to yo, and how to register
  • .codex-plugin/plugin.json + .mcp.json — Codex-specific layout; .mcp.json uses the client http transport
  • .claude-plugin/plugin.json + marketplace.json — Claude Code marketplace layout
  • glama.json — Glama directory ownership claim
  • server.json — official MCP Registry metadata for the hosted server. Its version is the registry record version, intentionally decoupled from the plugin manifests' 1.0.0; because the registry rejects duplicate versions and our token can publish but not edit io.github.alfongj-com/*, metadata corrections require a version bump (currently 1.0.1).

The Yo service itself is hosted and closed-source. This repo contains no server code and no secrets.
