This skill is documentation/reference material for building ChatGPT apps with mcp-use. All static analyzer findings are false positives: (1) 'Weak cryptographic algorithm' triggers on 'sha' substring in words like 'shape' - no actual crypto usage; (2) 'Ruby/shell backtick execution' detects markdown code fences, not shell commands; (3) 'System reconnaissance' and 'Hardcoded URL' are documentation patterns; (4) The critical heuristic 'Code execution + Network + Credential access' is triggered by documentation showing code examples with URLs and environment variables - standard documentation practice, not malicious behavior. This skill contains no executable code.

Risk findings

Confirmed security concerns are separated from items that still need review.

Confirmed security concerns (1)

RISK-001 Low
references/server-and-widgets.md:29
Environment Variable Access in Code Examples
Documentation shows process.env usage (e.g., process.env.MCP_URL). This is standard configuration pattern in code examples, not credential exfiltration.

Expert evidence

Immutable subject identity, scanner metadata, dismissed matches, and source-level evidence.

Hardcoded URLs in Documentation
URLs appear in documentation files (references/setup.md, references/csp-and-metadata.md). These are legitimate API endpoint references in documentation, not security issues.

The manifest and lockfile bind install artifacts to cryptographic hashes. This integrity claim is separate from the security assessment.
