MCP Stateless Check

MCP007 — The removed logging/setLevel method is still implemented
Severity error
Fixed by Upgrading your MCP SDK to a release targeting 2026-07-28
Transports stdio, http
Specification 2026-07-28
Changelog entry Major change 5 (SEP-2575)

Why this changed

Log level was session state, so logging/setLevel went with the session. It is now set per request via _meta, and servers MUST NOT emit notifications/message for requests that did not ask for it.

Running just this check

Terminal window
npx mcp-stateless --stdio "node dist/server.js" --only MCP007

Suppressing it

If this check does not apply to your server, skip it:

Terminal window
npx mcp-stateless --stdio "node dist/server.js" --skip MCP007

Rule ids are permanent and are never reissued, so a suppression cannot start silently matching a different check later.
