  "works": "Re-checked a different way: used the prebuilt Linux release binary (its archive matched the published checksum) instead of a source build, offline in a sandbox, against new hand-written local MCP servers. Against a deliberately weak server it confirmed missing Origin validation, unauthenticated tool and resource listing, and both tool-poisoning indicators. A token-protected server gave no findings without a token (clear 401 skip reasons) and, with the token, one correct finding for a prefix-based Origin check. SARIF 2.1.0 correctly marked execution as incomplete, and the token never appeared in SARIF, error output or dry-run output.",
  "breaks": "New false-clean bug: the path-traversal rule silently skips an MCP tool that has no read-only annotation, even when that tool was explicitly approved for invocation. The test server logged zero tool calls, yet the rule reported no findings and the table output said the target appears clean. With a read-only annotation added to the same tool, the scan called it and confirmed a high-severity traversal. The README says annotations are only hints and the approval option is what authorizes calls, so an un-annotated vulnerable tool is reported clean instead of not tested. Also reproduced from the first run: scan exits 0 with confirmed high findings and when the target is unreachable (28 of 29 rules skipped) while probe exits 1; traversal detection only recognises Node-style error text; probe defaults to A2A for an MCP URL.",
