MCP (Model Context Protocol) servers connect your agents to external services, databases, and APIs. Agent Studio maintains a global registry of MCP servers that any agent can use. Register a server once, then enable it for individual agents from their configuration page.

## Viewing registered MCP servers

To view your registered MCP servers and their available tools:

1. Select <Icon icon="puzzle-piece-simple" iconType="light" /> **Add-ons** from the left-hand navigation, then click <McpIcon /> **MCP**.
2. Select an MCP server to expand it.
3. Click <Icon icon="wrench" iconType="light" /> **List tools** to discover the server's available tools.

<Tip>
  To show MCP servers registered by plugins, click the <Icon icon="filter" iconType="light" /> **Filter** dropdown beside the search box at the top of the page and select **Show plugin items**.

## Registering an MCP server

To register an MCP server:

1. Select <Icon icon="puzzle-piece-simple" iconType="light" /> **Add-ons** from the left-hand navigation, then click <McpIcon /> **MCP**.
2. Click <Icon icon="plus" iconType="light" /> **Add**.
3. Enter a name for the server.
4. Select a transport method and configure the connection:

   <Tabs>
     <Tab title="Standard I/O (stdio)">
       Use stdio for MCP servers that run locally as a process on your machine.

       1. Enter the **Command** to start the server (for example, `npx` or `uvx`).
       2. Add any required **Arguments** for the command. Click <Icon icon="plus" iconType="light" /> **Add argument** to add additional arguments.
       3. (Optional) Add **Environment variables** as key-value pairs. Click <Icon icon="plus" iconType="light" /> **Add environment variable** to add additional variables.
       4. (Optional) Enter a **Working Directory** for the server process.
       5. Click **Add to Catalog**.
     </Tab>

     <Tab title="Server-Sent Events (SSE)">
       Use SSE for MCP servers that are hosted remotely or already running on your network.

       1. Enter the server's **URL** (for example, `http://localhost:3000/sse`).
       2. Click **Add to Catalog**.
     </Tab>
   </Tabs>

## Editing and deleting MCP servers

1. Select <Icon icon="puzzle-piece-simple" iconType="light" /> **Add-ons** from the left-hand navigation, then click <McpIcon /> **MCP**.
2. Click <Icon icon="ellipsis" iconType="light" /> on the server's row.
3. Select <Icon icon="pencil" iconType="light" /> **Edit** to modify the server's configuration, or select <Icon icon="trash" iconType="light" /> **Delete** to remove it.

<Note>
  Deleting an MCP server removes it from all agents that use it. Those agents will no longer have access to the server's tools.

  ***

  Servers registered by plugins cannot be edited or deleted from this page. Manage them through the plugin's own configuration.
</Note>

## Enabling an MCP server for an agent

Once a server is registered in the global catalog, you can enable it for individual agents from the agent's configuration page. See [MCP](/tools/anaconda-desktop/agent-studio/agents#mcp) for instructions.
