Any MCP server (HTTP)
http-mcp
A server you already run, or a hosted one, reached over HTTP. This is how you connect something that is not in the list above.
These are the fields Lob Bot puts in front of you when you add this connector, and the keys it stores them under. 1 of 2 is required. The one marked secret is sealed into a vault on your own machine and never reaches us.
Server URL
url
RequiredAuthorization header
authorization
OptionalSecret
This row names no example tools, and cannot: it has never seen the server you are about to point it at. The tools arrive when the server starts.
Whatever the server exposes, behind the same approval gate as every other tool in the thread.
A connector is added in Lob Bot, the desktop app. Values you enter are sealed into a vault on your own machine; the encryption key lives in your operating system’s credential store, not beside the vault, and the workspace database holds only a reference. Secrets are redacted by value as they are written, so a password inside a connection string is caught even though it does not look like one. Nothing is sent to us.
A bot reaches nothing until you give it a connector, and you choose the scope.
