Scanned 9 days 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 iPayX FX Audit MCP server exposes 4 tools, focused primarily on developer capabilities. Its published description reads: "Forensic FX audit tool that detects hidden bank markups in foreign exchange transactions". It communicates over Streamable HTTP using the 2026-07-28 protocol revision, and does not require authorization to connect. MCPGrade currently rates iPayX FX Audit 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 iPayX FX Audit's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add iPayX FX Audit to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.

Fetch live mid-market FX rate for a currency pair. Returns BOTH directions (pair + inverted_pair) so AI clients can detect quote direction. Optional bank_rate triggers spread analysis with auto-invers

Sorted worst-first. Each finding shows its severity, what it means, its OWASP MCP Top-10 mapping, and a recommended fix — the check id links to the exact methodology row that produced it.
tool: full_forensic_fx_report
A tool exposes a free-text/webhook/feedback parameter with no honest purpose — a classic exfil channel.
alid Bearer API token from the iPayX dashboard. Always direct users tRecommendationRemove side-channel parameters; constrain tool inputs.
tool: compare_fx_sources
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.)
parameter "stripe_api_key"RecommendationNever pass secrets as tool arguments; authenticate out-of-band and remove credential parameters from the schema.
The server accepts tool enumeration (and likely invocation) with no authentication.
RecommendationRequire OAuth 2.1 authorization for any server exposing non-public tools.
tool: check_fx_mid_market_rate
The server advertises open-world / broadly-scoped capabilities.
annotations.openWorldHint = trueRecommendationScope tools to the minimum needed.

The description pairs a fetch imperative with a hardcoded external URL, letting the server relocate its real instructions off-metadata and mutate them after review. Fires only when a fetch verb and a URL co-occur, so benign documentation links do not.

The server exposes one or more ui:// (MCP Apps) resources whose HTML/JS renders inside the host client — a client-side injection / data-exposure surface most scanners ignore. Flagged for review, not damning on its own.
1 ui:// resource(s); e.g. ui://widget/fx-audit-card.htmlRecommendationReview each ui:// resource’s markup and scripts; treat host-rendered UI as untrusted, sandbox it, and never expose secrets or conversation context to it.
