Full Analysis
- [REMOTE_CODE_EXECUTION]: The skill instructs users and agents to execute unverified remote code via a piped shell command:
curl -sSL https://raw.githubusercontent.com/caiovicentino/polymarket-mcp-server/main/quickstart.sh | bash. This pattern is highly insecure as it executes a script from an external repository directly in the system shell without prior inspection. - [EXTERNAL_DOWNLOADS]: The installation process relies on cloning a third-party repository from GitHub (
github.com/caiovicentino/polymarket-mcp-server) and executing local scripts (install.sh,quickstart.sh) which are outside the immediate package's static control. - [INDIRECT_PROMPT_INJECTION]: The skill is designed to ingest and analyze untrusted data from prediction markets, which can be manipulated by third parties to influence the agent's behavior.
- Ingestion points: Data enters the context through market discovery tools (
search_markets,get_trending_markets) and detailed market lookups (get_market_details). - Boundary markers: None identified; market descriptions and titles are processed as natural language instructions for the analysis tools.
- Capability inventory: The skill has high-privilege capabilities including placing limit orders (
place_limit_order), market orders (place_market_order), and performing "smart trades" (smart_trade) based on processed instructions. - Sanitization: There is no evidence of sanitization or filtering for market-provided content before it is passed to AI-powered analysis tools like
analyze_market_opportunityoroptimize_portfolio.
Recommendations
- HIGH: Downloads and executes remote code from: https://raw.githubusercontent.com/caiovicentino/polymarket-mcp-server/main/quickstart.sh - DO NOT USE without thorough review
- AI detected serious security threats
