# External MCP Servers

> Connect SSE-based MCP Servers to Siloed

Siloed connects to third-party SSE-based MCP Servers.
The external server's [resources](https://modelcontextprotocol.io/docs/concepts/resources) are shown as [capsules](/concepts/capsules).

<Note>
  To use an external MCP server, the server must support resources. Many MCP servers only support [tools](https://modelcontextprotocol.io/docs/concepts/tools).
</Note>

To connect to an external MCP server, add a connection using the server's SSE URL.

## Capsules

* The MCP server's resources determine the available capsules.
* [Text-based resources](https://modelcontextprotocol.io/docs/concepts/resources#text-resources) are supported. [Binary resources](https://modelcontextprotocol.io/docs/concepts/resources#binary-resources) may be supported in the future.

## Tools

Siloed does not support tools (or prompts) on MCP server connections.
Use other connection types to unlock tools on Siloed's MCP Server.
