Security audit

Ambil jadwal sholat (imsak, subuh, dzuhur, ashar, maghrib, isya) untuk kota/kabupaten di Indonesia dari API Muslim api.myquran.com (sumber Kemenag Bimas Islam). Gunakan saat user minta jadwal sholat hari ini / tanggal tertentu / 1 bulan untuk lokasi tertentu, atau butuh mencari ID kab/kota.

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Indonesian prayer-time lookup tool that sends location/date requests to api.myquran.com and does not show hidden persistence, credential access, or destructive behavior.

Install only if you are comfortable sending Indonesian location keywords or location IDs, requested dates/months, and timezone values to api.myquran.com. Expect Indonesian output and note that monthly results are currently a 7-day preview rather than a full month in the helper script.

  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
89% confidence
Finding

The skill clearly relies on outbound network access to query api.myquran.com, but the manifest does not declare any tool scope such as allowed-tools or permissions. This is a real security hygiene issue because it weakens least-privilege controls and makes the skill's external communication capabilities implicit rather than explicit.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
96% confidence
Finding

All user-facing natural-language strings in the docstring and command output are in Indonesian, and the tool does not provide an opt-in or alternative language selection. The policy requires flagging language or locale constraints when they are forced without user choice or explicit justification.

Intent-Code Divergence

Low
Category
Not specified by scanner
Confidence
98% confidence
Finding

The top-level docstring lists id-bulan <id> <YYYY-MM> as a supported command, but the parser actually defines id-period and never registers id-bulan. This is an active documentation-to-code contradiction, not just an omitted detail.

Missing User Warnings

Low
Category
Not specified by scanner
Confidence
83% confidence
Finding

This code sends user-provided keyword and timezone values to an external API using HTTP requests, but the CLI help and printed output do not disclose that entered data will be transmitted off-system. For a code file, outbound network transmission of user data should have some visible warning, confirmation, or clear disclosure unless it is explicitly communicated as part of the interface.

Content

No source excerpt is available for this finding.

Description-Behavior Mismatch

Low
Category
Not specified by scanner
Confidence
95% confidence
Finding

The manifest description explicitly says the skill should be used when the user requests a 1-month prayer schedule for a location. In code, cmd_bulan fetches monthly data but intentionally prints only the first 7 days (keys[:7]) and even labels it as a preview, so the implemented behavior is narrower than the claimed capability.
