Affected AI clients will execute \`kahin\` as a configured MCP server on later use. - **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:** 0.3.10 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. npm postinstall mutates detected third-party AI-agent configuration files, registering the package as an MCP server without a user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-09T19:40:47.452Z - **Finished:** 2026-08-09T19:41:35.677Z - **Download time:** 503 ms - **Static scan time:** 67 ms - **AI review time:** 47654 ms - **Total time:** 48225 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall mutates detected third-party AI-agent configuration files, registering the package as an MCP server without a user command. - **Trigger:** Installing @kahinmcp/kahin@0.3.10 with lifecycle scripts enabled. - **Impact:** Affected AI clients will execute \`kahin\` as a configured MCP server on later use. - **Evidence paths:** package.json, bin/setup.mjs, bin/kahin.mjs, lib/kahin-0.3.10-py3-none-any.whl - **Review source:** ai\_review - **Reviewed:** 2026-08-09T19:41:35.677Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic broad MCP client configuration injection - **Attack narrative:** The postinstall hook invokes setup(), which enumerates existing configurations for 22 AI clients and writes a \`kahin\` MCP entry into every detected config. This is an unconsented install-time mutation of broad foreign AI-agent control surfaces, causing those clients to launch the package later. - **Rationale:** Direct inspection confirms a concrete default postinstall control-surface mutation, not merely a scanner heuristic. Opt-out and idempotence do not provide prior consent. - **Files touched:** package.json, bin/setup.mjs, ~/.claude.json, ~/.cursor/mcp.json, ~/.config/Code/User/mcp.json, ~/.codex/config.toml ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs \`node bin/setup.mjs\` at postinstall., bin/setup.mjs auto-detects 22 unrelated AI clients by user config paths., setup() runs by default unless KAHIN\_SKIP\_AUTO\_SETUP or CI is set., upsertJson/TOML/YAML silently adds a \`kahin\` MCP command to each detected client config. - **Evidence against:** Launcher installs the bundled wheel locally; no package-controlled network endpoint appears in bin scripts., The config mutation is idempotent and has an opt-out, but is still default install-time behavior. ## Public findings ### 1.
