AI tools receive persistent configuration that can launch package code in subsequent sessions without separately authorized setup. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.0.7 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. An automatic npm postinstall silently modifies global configurations belonging to multiple AI agents. It registers the package as an executable MCP server without a consent gate. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-02T10:15:38.490Z - **Finished:** 2026-10-02T10:16:55.965Z - **Download time:** 510 ms - **Static scan time:** 359 ms - **AI review time:** 76604 ms - **Total time:** 77475 ms The recorded confidence comes from the underlying analysis.

It registers the package as an executable MCP server without a consent gate. - **Trigger:** Installing the package with npm lifecycle scripts enabled. - **Impact:** AI tools receive persistent configuration that can launch package code in subsequent sessions without separately authorized setup. - **Evidence paths:** package.json, bin/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-10-02T10:16:55.965Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall invokes self-install, which unconditionally calls the global registration routine and writes MCP server entries under the user's home directory. - **Attack narrative:** Installation runs the CLI's silent self-install command. Before checking whether the current directory is inside node\_modules, that command registers global MCP servers. The routine points those servers at the package's CLI and writes configuration for multiple independent AI tools. No consent prompt guards these writes. The inspected target near line 643 merely reads registration status, but the traced install handler independently establishes automatic global mutation. - **Rationale:** The inspected source proves unconsented postinstall mutation of a broad, foreign AI-agent control surface. This meets the blocking policy regardless of whether the local MCP tools otherwise serve the package's advertised purpose. - **Files touched:** .cursor/mcp.json, .claude.json, .codeium/windsurf/mcp\_config.json, .gemini/config/mcp\_config.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically runs silent self-install during postinstall., The self-install handler registers global MCP servers without a consent prompt, including inside node\_modules., Global registration configures agents to launch this package's CLI as an MCP server., The registration routine writes the server entry into existing or newly created agent configuration files., Global targets include Claude Code, Windsurf, and Gemini configurations under the user's home directory. - **Evidence against:** The registered MCP command launches local package code; these excerpts do not establish remote payload execution or credential theft. ## Affected versions and remediation This report applies to tokenshield-contextplus@1.0.7. - Avoid installing tokenshield-contextplus@1.0.7. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
