Session URL shorthand for Custom Agent session tools
Notion MCP's session tools now resolve short session:// and thread:// URLs against the connected workspace instead of requiring the full form.
Notion MCP's Custom Agent session tools now accept a shorthand for session URLs: session://sessionId or thread://sessionId, both resolved against the connected workspace. The full session://spaceId/sessionId form that the tools return still works, and a full URL naming a different workspace still returns an HTTP 400 validation error.
