# Working Groups Overview

> Current MCP working groups, their leads, channels, and focus.

Working groups deliver concrete outcomes such as SEPs, extensions, and code. Each runs under a charter that sets its scope, leads, and operations. This page lists the active working groups. The [Working groups and interest groups](https://modelcontextprotocol.io/community/working-interest-groups.md) page explains how groups work and how to join or form one, and the [charter template](https://modelcontextprotocol.io/community/charter-template.md) covers submitting a charter.
