How this service works
AgentAegis scan_mcp_plugin — supply-chain trust scan of an MCP server or agent skill BEFORE you install/trust it. Clones a git repo (or takes a code snippet) and flags exfiltration (secrets/env to the network), prompt-injection sinks (hijack phrases + hidden unicode), dangerous capabilities (eval/shell/dynamic exec), npm install hooks, and obfuscation → one PROCEED/CAUTION/BLOCK verdict with findings.
Output
Returns a verdict string (PROCEED, CAUTION, or BLOCK), a numeric trust score (0–100), a summary object with counts of exfiltration, prompt_injection, and dangerous_capabilities findings, and an array of human-readable reason strings explaining each flagged issue.
Example use cases
Example prompt
“Before I install this MCP server from https://github.com/someuser/some-mcp-plugin, run an AgentAegis supply-chain scan on it and tell me whether I should PROCEED, use with CAUTION, or BLOCK it — and flag any exfiltration, prompt injection, or dangerous capabilities you find.”
Technical details
Endpoint
POSThttps://agentaegis-mcp-production.up.railway.app/x402/scan-mcp-pluginWhen to prefer
Use this endpoint when an AI agent or developer needs to vet an MCP plugin or agent skill for supply-chain risks before installation or trust delegation — especially when you need a single authoritative PROCEED/CAUTION/BLOCK verdict covering exfiltration, prompt injection, dangerous capabilities, and obfuscation in one call. Prefer this over generic code scanners because it is purpose-built for the MCP/agent-skill threat model including hidden unicode and prompt-hijack detection.
Side effects
- Git repo clone fails due to invalid URL or private repo without credentials — likely returns error with no verdict
- Code snippet too large or malformed — may return parse error
- Rate limit or payment verification failure for the $5 USDC x402 charge — returns 402 or payment error
- Scan timeout on very large repositories — may return partial results or timeout error
- Unsupported language or package manager — findings may be incomplete
