Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection found a guarded CI setup hook and affirmative opt-in for telemetry identity collection and event delivery. The scanner’s similarity and lifecycle hints did not establish malicious behavior in the reviewed source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-21T18:41:53.232Z - **Finished:** 2026-10-21T18:44:20.691Z - **Download time:** 1777 ms - **Static scan time:** 1621 ms - **AI review time:** 144060 ms - **Total time:** 147459 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No attack was identified in the inspected source. The install hook has an explicit opt-in before writing a project workflow, and telemetry requires affirmative opt-in before identity collection and event delivery. - **Trigger:** Postinstall runs during installation; workflow creation requires the project setting or environment opt-in. Telemetry delivery requires affirmative telemetry opt-in. - **Impact:** No confirmed unauthorized project mutation, credential disclosure, or other attack impact was established from the inspected behavior. - **Review source:** ai\_review - **Reviewed:** 2026-10-21T18:44:20.691Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook may create a new MCP Observatory workflow in an MCP project. Opted-in telemetry sends events to the configured telemetry endpoint. - **Rationale:** Source inspection found a guarded CI setup hook and affirmative opt-in for telemetry identity collection and event delivery. The scanner’s similarity and lifecycle hints did not establish malicious behavior in the reviewed source. - **Files touched:** scripts/postinstall.mjs, dist/src/telemetry.js, dist/src/handshake.js - **Network endpoints:** mcp-observatory-telemetry.kryptosai.workers.dev ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook skips self-installs, CI, disabled runs, and projects that do not appear to use MCP; it creates a workflow only when an environment setting or project configuration explicitly enables setup., Telemetry does not request policy or inspect identity before affirmative opt-in. Events are sent by POST to the configured telemetry endpoint after initialization enables telemetry., MCP configuration protection is exposed as an explicit function that reads a selected configuration file; the inspected discovery helper only identifies candidate files., Inspected the flagged scanner, runtime, adapter, authentication, usage, and support modules, along with the prepared MCP SDK, CI metadata, and CLI dependencies; the reviewed behavior supports the package’s MCP security and CLI functions., The inspected dependency code delegates MCP request streams and checks task states, validates OAuth URL and resource inputs and formats OAuth errors, and provides CLI argument validation, executable spawning, and error types., The CLI helper filters hidden commands from help, and option flags are derived from the supplied flag string. - **Evidence against:** The package declares a postinstall hook, but the inspected hook’s project configuration write is guarded by explicit setup opt-in and does not run in CI., The telemetry code collects host and repository identity only after affirmative opt-in, and sends events through its configured telemetry endpoint. ## Affected versions and remediation This report applies to @kryptosai/mcp-observatory@1.50.0. - Review the evidence and your use of @kryptosai/mcp-observatory@1.50.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
