What
Reading an @-mentioned MCP resource now uses the shared reader helper and respects the session abort signal.
Details
- the abort signal is passed with context "MCP @-mention resource read"
- an aborted read returns quietly instead of logging an error
- server state acceptance now uses the connectivity predicate rather than requiring
type === "connected"
Evidence
MCP @-mention resource read
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
