Struct ListTasksResult 

#[non_exhaustive]
pub struct ListTasksResult {
    pub tasks: Vec<Task>,
    pub next_cursor: Option<String>,
}

List tasks result — v1-only (2025-11-25).

There is no v2 counterpart and no projection type: tasks/list is ABSENT from the io.modelcontextprotocol/tasks extension and answers -32601 on a v2-negotiated request (inventory row 37, plan 114-08). The removal is a SECURITY improvement — with no enumeration primitive a server cannot leak the existence of one caller’s tasks to another. Kept unchanged for v1.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

tasks: Vec<Task>

List of tasks

next_cursor: Option<String>

Pagination cursor for next page
