DeFi financial intelligence for AI agents, providing oracle data and market verification.

A critical issue was found. Do not connect this server as-is.
Scanned 1 month ago Due for re-check
A server can change after it's graded. Re-run the automated scan to refresh this report.
This grade is deterministic and reproducible: the same server surface always yields the same grade under a given algorithm version. It is a real automated assessment computed by the MCPGrade engine from what the probe actually observed — not a fabricated or opinion score. It is not a manual human pentest, so it can miss context-specific risks.
Every signal below was measured directly by the automated probe. The grade is derived only from evidence like this — nothing is assumed.
The PreFlyte MCP server exposes 9 tools, focused primarily on general-purpose capabilities. Its published description reads: "DeFi financial intelligence for AI agents, providing oracle data and market verification". It communicates over Streamable HTTP using the 2025-06-18 protocol revision, and does not require authorization to connect. MCPGrade currently rates PreFlyte F — a critical issue was found and the server should not be connected as-is. Its most notable findings include "Data-exfiltration parameters" and "Tool input schema requests a secret". This report is a deterministic, reproducible automated assessment: the same observed surface always yields the same grade under a given algorithm version, and it is refreshed as new scans arrive and free to read — but it is not a substitute for a manual human security review. Always re-check PreFlyte's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add PreFlyte to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.

tool: get_returns
A tool exposes a free-text/webhook/feedback parameter with no honest purpose — a classic exfil channel.
Args: api_key: Your PreFlyte API key (required). chaiRecommendationRemove side-channel parameters; constrain tool inputs.
tool: get_returns
The input schema declares a parameter that asks the caller to hand over a password, key, token, or other secret — a credential-harvest / token-passthrough risk. (Bare pagination `token` params are excluded.)
