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. The inspected behavior fits a presence and messaging MCP package: invisible characters are stripped during handle normalization, setup configures the agent server through the CLI setup flow, and the checked credential-bearing requests go to the package’s own service. The routing hints did not establish an attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-31T13:29:25.061Z - **Finished:** 2026-10-31T13:29:49.393Z - **Download time:** 770 ms - **Static scan time:** 1483 ms - **AI review time:** 22078 ms - **Total time:** 24332 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. The flagged Unicode sequence is used to strip invisible handle characters; setup writes agent configuration through the setup flow, and inspected authenticated requests go to the package’s own service. - **Trigger:** MCP server startup, explicit setup/onboarding, or user-invoked tools. - **Impact:** No malicious impact identified in the inspected paths. - **Review source:** ai\_review - **Reviewed:** 2026-10-31T13:29:49.393Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Handle normalization removes invisible controls. Setup adds the server to agent configuration. Authenticated API calls use the service URL; the inspected tip call requires a positive supplied amount. - **Rationale:** The inspected behavior fits a presence and messaging MCP package: invisible characters are stripped during handle normalization, setup configures the agent server through the CLI setup flow, and the checked credential-bearing requests go to the package’s own service. The routing hints did not establish an attack. - **Files touched:** Claude Code and Cursor MCP configuration files (paths selected by setup) - **Network endpoints:** https://www.slashvibe.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 package describes itself as an MCP server for presence and messaging., The flagged invisible and bidi characters are handled by a regex that strips them when normalizing handles., Setup is routed through the CLI’s explicit setup command or the \`vibe-setup\` binary., Setup writes MCP server configuration for Claude Code and Cursor as part of its setup flow., The inspected credential-bearing requests target the package’s own \`www.slashvibe.dev\` service; the tip request runs only when a positive tip amount is supplied. - **Evidence against:** The main entry starts the MCP server when loaded, which is expected for the declared server purpose., Setup has an autorun-on-require behavior, though the inspected CLI routes it through setup or first-run terminal onboarding. ## Affected versions and remediation This report applies to slashvibe-mcp@0.8.25. - Review the evidence and your use of slashvibe-mcp@0.8.25 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.
