**MCP** is used to connect callable tools or external services to SuperMagic. You can add available MCPs to a conversation, select and call them using `@`; if no MCP meets your needs, you can also create and configure one yourself.

## What Is MCP

**MCP plugins** extend the capabilities that SuperMagic can call. When creating an MCP, you can enter a plugin name and description, then configure callable capabilities for the plugin through **Import Existing Tools** or **Custom MCP**.

If the page already contains an MCP that meets your needs, you can add it directly to the current conversation. If not, you can start the creation process and configure existing tools or external services for the MCP.

## Open the MCP Management Page

1. On the conversation page, click the **MCP Plugins** icon in the lower-right corner of the input box.

![Click the MCP Plugins entry in the lower-right corner of the conversation input box](https://www.letsmagic.cn/help/docs/docs/2026-08-19/c5a50611-e107-4ace-a4cb-be3b9d083725.jpg)

After opening it, you can view, search for, and add MCPs on the page.

## About the MCP Plugins Page

The **MCP Plugins** page contains two tabs: **Official Plugins** and **Custom Plugins**. These are tab names on the page used to distinguish different lists; they do not represent two types of MCPs.


| Page Entry           | Available Operations                                               |
| -------------------- | ------------------------------------------------------------------ |
| **Official Plugins** | View, search for, and add the MCPs displayed in this tab.          |
| **Custom Plugins**   | View MCPs you created, or start the **Create MCP Plugin** process. |


When you need to create an MCP:

1. Switch to the **Custom Plugins** tab.
2. Click **Create MCP Plugin** in the upper-right corner.

If you do not have any custom plugins yet, the page displays **No Plugins**.

![The Custom Plugins tab displays the entry for creating an MCP](https://www.letsmagic.cn/help/docs/docs/2026-08-19/607f3b3f-ac1a-47a4-a488-e9fe1945f31f.png)

After creation is complete, the MCP appears in the **Custom Plugins** list. The list provides **Manage Permissions**, **Configure**, and **Add** entries.

## Confirm the MCP Usage Scope

The MCP list may display **Manage Permissions**, but this entry does not mean that you can assign an MCP you created to other members of the organization.

After opening **Manage Permissions**, **Personal Organization** in the current screenshot displays only the creator, with the role **Creator** shown on the right.

![The MCP permissions page displays only the creator](https://www.letsmagic.cn/help/docs/docs/2026-08-19/5d264403-1fde-4afa-b50b-fbec5b2a829f.png)

On the current page, an MCP you create can only be used by the creator.

## How to Use MCP

If an MCP is already available, you can add it directly to a conversation and use it. You only need to create and configure an MCP yourself when no MCP meets your needs.

1. Open **MCP Plugins** and view the existing MCPs under **Official Plugins** or **Custom Plugins**.
2. Add the MCP you need to the current conversation.
3. In the conversation input box, select the MCP using `@` and send your request.
4. If no MCP meets your needs, go to **Custom Plugins** to create and configure an MCP.

For information about adding and calling MCPs in a conversation, see \[Use MCP in a Conversation\]; for information about creating, modifying, and deleting MCPs, see the \[Create and Manage MCP\] documentation.
