Runtime network activity is the declared scraping/OAuth service; the install hook only customizes its FastMCP consent page. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 93.0% - **Started:** 2026-08-08T11:33:15.925Z - **Finished:** 2026-08-08T11:33:48.336Z - **Download time:** 255 ms - **Static scan time:** 89 ms - **AI review time:** 32066 ms - **Total time:** 32411 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. Runtime network activity is the declared scraping/OAuth service; the install hook only customizes its FastMCP consent page. - **Trigger:** User starts the MCP server or invokes its scraping tools; postinstall runs during npm installation. - **Impact:** User-supplied URLs and optional cookies are sent to the configured Spidra service as part of requested scraping. - **Evidence paths:** package.json, dist/index.js, scripts/patch-fastmcp-consent.mjs, scripts/preview-consent.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-08T11:33:48.336Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** MCP scraping client with optional OAuth and a dependency consent-UI patch - **Rationale:** The scanner conflates normal OAuth/API credential handling with exfiltration. The postinstall dependency patch is visible, narrowly targets a consent-screen method, and does not establish malicious behavior. - **Files touched:** package.json, dist/index.js, scripts/patch-fastmcp-consent.mjs, node\_modules/fastmcp/dist/\*.js - **Network endpoints:** https://claude.ai/api/mcp/auth\_callback ### Review decision - **Verdict:** Clean - **Confidence:** 93.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall., scripts/patch-fastmcp-consent.mjs rewrites a FastMCP dependency consent-screen method. - **Evidence against:** dist/index.js is an MCP wrapper around the declared Spidra scraping client., Credentials are used for Spidra API/OAuth authentication, not harvested from files., The OAuth introspection POST is limited to the configured SPIDRA\_API\_URL., The patched consent UI retains scope display and explicit approve/deny actions., No payload download, shell execution in runtime code, persistence, or foreign agent-config writes found. ## Public findings ### 1.
