Foreign AI clients can be silently configured to launch the package's MCP server. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.3.2 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package automatically modifies detected configurations for numerous unrelated AI-agent clients. It registers kahin as an MCP server, causing those clients to invoke the package later. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T21:34:09.832Z - **Finished:** 2026-08-05T21:35:02.040Z - **Download time:** 504 ms - **Static scan time:** 55 ms - **AI review time:** 51648 ms - **Total time:** 52208 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically modifies detected configurations for numerous unrelated AI-agent clients. It registers kahin as an MCP server, causing those clients to invoke the package later. - **Trigger:** npm postinstall of @kahinmcp/kahin@0.3.2 - **Impact:** Foreign AI clients can be silently configured to launch the package's MCP server. - **Evidence paths:** package.json, bin/setup.mjs, bin/kahin.mjs, lib/kahin-0.3.2-py3-none-any.whl - **Review source:** ai\_review - **Reviewed:** 2026-08-05T21:35:02.040Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented broad AI-agent MCP configuration injection - **Attack narrative:** At npm postinstall, bin/setup.mjs scans for existing configurations belonging to 22 AI CLI/editor clients and adds a kahin MCP entry to every configuration it finds. This is not limited to a package-owned integration or an explicit setup command. The injected command later starts the bundled Python MCP server through bin/kahin.mjs. - **Rationale:** The postinstall hook performs unconsented mutation of a broad, foreign AI-agent control surface. This meets the blocking policy regardless of the package's stated browser-automation purpose. - **Files touched:** package.json, bin/setup.mjs, ~/.claude.json, ~/.codex/config.toml, ~/.config/Code/User/mcp.json, ~/.config/opencode/opencode.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs bin/setup.mjs via postinstall., bin/setup.mjs automatically enumerates 22 third-party AI client configurations., setup() writes a kahin MCP entry into each detected client config without consent., Targets include ~/.claude.json, ~/.codex/config.toml, VS Code storage, and multiple editor-agent configs., The installed entry invokes the package's kahin command, extending agent control surfaces. - **Evidence against:** No install-time network request is present in the Node setup code., Config changes are idempotent and skipped when KAHIN\_SKIP\_AUTO\_SETUP or CI is set., The bundled wheel is a readable Python package; its sidecar is an ELF browser component, not an opaque archive payload. ## Public findings ### 1.
