prowlarr-search

Security checks across malware telemetry and agentic risk

Overview

This is a straightforward Prowlarr search helper with a real API-key handling caution but no evidence of hidden, destructive, or unrelated behavior.

Install only if you intend to let the agent search your own trusted Prowlarr instance. Prefer localhost or HTTPS, avoid routing the request through untrusted proxies, treat PROWLARR_API_KEY as sensitive, and rotate it if it may have been exposed in logs.

MCP Least Privilege
Confidence
91% confidence
Finding
The skill invokes a Python script that requires environment variables and makes external API calls to a Prowlarr server, but the skill does not explicitly declare corresponding permissions. This creates a transparency and policy-enforcement gap: users and hosts may not realize the skill can access secrets and perform network operations, increasing the risk of unintended data exposure or unauthorized outbound requests.

Missing User Warnings

Medium
Confidence
97% confidence
Finding
The script places the API key directly in the query string, which can leak through logs, browser/history equivalents, reverse proxies, monitoring systems, and upstream servers. This is made more concerning because the default transport is plain HTTP to localhost, and the base URL is configurable, so the key could be exposed to non-local endpoints if misconfigured.
