# Restrict MCP server access to a custom registry

You can configure an MCP registry URL and access control policy to determine which MCP servers developers can discover and use in supported IDEs and Copilot CLI (コパイロット CLI).

> \[!IMPORTANT] This feature is in パブリック プレビュー and is not the recommended method for restricting access to MCP servers. The more secure, generally available method is to define settings in your enterprise's `managed-settings.json` file. See [Configuring an MCP server allowlist for your enterprise](/ja/copilot/how-tos/administer-copilot/manage-mcp-usage/configure-enterprise-allowlist).

## Prerequisites

Before you can fully configure MCP server access for your company, you need to create an MCP registry. See [組織または企業の MCP レジストリを構成する](/ja/copilot/how-tos/administer-copilot/manage-mcp-usage/configure-mcp-registry).

## Configuring the MCP allowlist policy for an enterprise

To ensure uniform access, you can set and maintain your MCP registry URL and allowlist policy at the enterprise level. Otherwise, if your teams have different needs, you should configure separate policies for each organization.
