How to connect a custom MCP server
You need the server’s HTTPS URL and, depending on the server, a credential. There are two places to add one.- Customize → Connectors
- Settings → Connectors
The quickest way, for servers that sign you in with OAuth or need no credentials.
1
Open the form
Open Customize → Connectors and click Add. The Add custom connector dialog opens.
2
Name the server
Enter a Name, for example
acme-crm. It’s shown in the connectors list and saved as a lowercase slug.3
Enter the URL
Enter the MCP server URL, the HTTPS address where the server accepts MCP requests, for example
https://mcp.example.com/mcp.4
Add it
Click Continue. The server appears in the catalog under the Custom category. Open it to connect and to see the tools it offers.
Requirements
- The URL must be reachable from the public internet. Vibely refuses URLs that point at
localhostor private network addresses. - Use an HTTPS URL. The Customize → Connectors form only accepts
https://. - Each server name must be unique in your account.
What the agent can do with it
Once connected, the agent can call the server’s tools during your builds, in any of your projects. The same approval rules apply as for catalog connectors: read-only tools run without asking, while tools that create, change, delete, or send something ask for your approval first.
Manage custom MCP servers
- Remove a server: in Settings → Connectors, click Remove next to it. This deletes its stored API key or OAuth token.
- Change the URL or credentials: remove the server and add it again.
- Workspace controls: on the Business plan, an admin can turn off Remote MCP connectors in Settings → Privacy & security. That withholds every MCP server, custom ones included, from the agent across the workspace. See Admin controls.
