Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.2.171 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 manifest has no install lifecycle hook, and the inspected runtime behavior matches its declared local-device MCP purpose. Static hints about process helpers and a runtime dependency bridge did not establish an attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-21T17:38:30.526Z - **Finished:** 2026-10-21T17:39:16.138Z - **Download time:** 520 ms - **Static scan time:** 1462 ms - **AI review time:** 43629 ms - **Total time:** 45612 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 surface was identified in the inspected source. The package exposes local device tools through an MCP runtime. - **Trigger:** A user or paired ReMCP agent starts the runtime and invokes an exposed tool. - **Impact:** No malicious effect was established from the reviewed behavior. - **Review source:** ai\_review - **Reviewed:** 2026-10-21T17:39:16.138Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime serves tool requests over stdio; screenshot capture may load the declared D-Bus library, and file operations use caller-supplied paths. - **Rationale:** The manifest has no install lifecycle hook, and the inspected runtime behavior matches its declared local-device MCP purpose. Static hints about process helpers and a runtime dependency bridge did not establish an attack. ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json declares the stdio runtime entrypoint and has no install lifecycle hook; its dependencies support D-Bus screenshots and MCP serving., src/index.mjs starts the local MCP server. File writing uses caller-provided paths resolved through the runtime safety layer, and screenshots use the declared D-Bus dependency., The reviewed dependency entrypoints implement D-Bus and MCP functionality; no concrete malicious behavior was identified in the inspected source. ## Affected versions and remediation This report applies to @remcp/runtime@0.2.171. - Review the evidence and your use of @remcp/runtime@0.2.171 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.

Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 10. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** src/tools/files-screenshots.mjs\#virtual:normalized:round1 - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review. Public source snippet (untrusted): ```text stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 2 ``` ### 11. High: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** src/extended/common.mjs - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = previous_version_dangerous_delta matchedPackage = @remcp/runtime@0.2.167 matchedIdentity = npm:QHJlbWNwL3J1bnRpbWU:0.2.167 similarity = 0.948 summary = stored previous version shares package body but lacks this dangerous source file ``` ### 12. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 88.0% - **Path:** package.json - **Public source:** [View source]() package.json declares the stdio runtime entrypoint and has no install lifecycle hook; its dependencies support D-Bus screenshots and MCP serving.
