How this service works
Analyze an MCP server manifest for security risk before install — destructive actions, over-broad scopes, sensitive-data egress, weak auth, prompt-injection surface, and permission diff. Returns per-tool, per-factor findings with severity, why, and a concrete fix (not just a score).
Output
A JSON object containing a risk level (e.g. 'critical'), a status of 'scored', a breakdown of risk factors (weak-auth, over-broad-scope, sensitive-egress, destructive-action each scored 0 or 1), total findingsCount, a requiresApproval boolean, and a recommendedAction string such as 'block_install_until_scoped_and_approved', plus a unique requestId.
Example use cases
Example prompt
“Before we install this MCP server, run a Hermes Plant risk score on it — I need to know if it has weak auth, overly broad scope, or any destructive actions, and whether it should be blocked until approved.”
Technical details
Endpoint
GEThttps://hermesplant.com/api/agent-services/mcp-risk/scoreWhen to prefer
Use this endpoint when an AI agent operator or orchestration layer needs to gate-check an MCP server or tool plugin before installation or execution — especially in regulated, enterprise, or high-stakes trading environments where weak auth, sensitive data egress, or destructive tool calls pose meaningful risk. Prefer this over manual review when you need a deterministic, test-backed score with a clear pass/block recommendation.
Side effects
- Missing or malformed MCP server payload returns 400 with validation error
- Insufficient USDC balance or x402 payment failure returns 402
- Unrecognized MCP schema version may result in incomplete scoring
- Network timeout returns 504 with no score produced
- Rate limiting may return 429 if too many calls in a short window
