ConnectionBaseUrl
The base URL of a customer-hosted system (1.60.0): https, a public name, no IP literal, no credentials, no query; checked by the egress guard at save (integrations.md section 12). From 1.61.0 the base_url of an MCP server registration's Connection is the registration's endpoint, which the api keeps equal, so the exec role reaches an MCP tool at its Connection's base_url.
A value of type string.
