# MCP server usage in your company

You can manage MCP server usage to provide your developers with valuable tools while maintaining security and compliance.

Le protocole MCP (Model Context Protocol) est une norme ouverte qui définit la façon dont les applications partagent le contexte avec de grands modèles de langage (LLMs). MCP fournit un moyen standardisé de connecter des modèles IA à différentes sources de données et outils, leur permettant ainsi de travailler ensemble plus efficacement.

You can manage MCP server usage in your organization or enterprise by configuring MCP policies on GitHub.

The **MCP servers in Copilot** policy defines whether MCP servers can run at all across Copilot clients. We recommend keeping this policy enabled and, if necessary, restricting the MCP servers that users can run to an approved list.

## MCP allowlists

The recommended method for creating an allowlist is to use your enterprise's `managed-settings.json` file. This allows you to apply settings across clients that users cannot override.

Alternatively, you can host your own MCP registry and restrict access to servers in the registry. However, this method has weaker enforcement than `managed-settings.json`.
