Add any MCP server
Give June the tools of any service that offers an MCP server: add its address, sign in, and June can use its tools in your chats.
Many services offer their tools as an MCP server: a web address that lists what the service can do in a standard format. Add that address on the Integrations page and June can use the service's tools in your chats, even when June has no integration of its own for it.
https://.What June can do
June gets every tool the server offers and uses it as the account you signed in with: what the server's tools can read and change, June can too. Changes follow your approval settings. Review the requested action and account before approving; the server provides the tool’s description.
Use it in an organization
A server you add on the Integrations page reaches your organizations like any personal connection (personal or organization).
An organization's admins can also offer a server to everyone in it: on the organization's page, Add MCP server opens Add integration for the organization. If the server uses sign-in, June starts the adding admin's own sign-in immediately. Other members connect their own login in the organization's Integrations section, with the server's sign-in, a token, or one click when the server needs no login. That connection works only in that organization. If you already have the same server on your own Integrations page and it reaches your organizations, the row shows it connected.
When an admin removes the server (Remove server in its row's menu), it stops working in the organization for everyone at once. Your connection stays on your Integrations page, marked No longer offered by the organization, until you disconnect it.
When something changes
- If adding the server stopped before its sign-in page opened, open its integration page and connect again. You do not need to add the server again.
- If the service adds or changes tools, choose Refresh tools in the row's menu.
- If the sign-in lapses, the row reads Re-auth required; choose Re-auth.
- To remove the server, open it from its row and choose Remove integration.
What June does not do
- It connects only to servers on the public internet over HTTPS, on the standard port, with no username or password in the address: not to an address on your own computer or private network.
- June can ask you to approve a tool before it runs. It cannot answer a question the server asks while the tool is already running; it declines that question. If the tool needs more information, supply it in your request and try again, or complete that step in the service itself.
- It does not run MCP servers that you would start on your own computer (local, command-line servers).
- It cannot switch single tools of a server on or off; June gets all of them. Add only servers you trust with what their tools can do.
