Seven utility tools covering exchange rates, UUIDs, hashing, Base64, timestamps, and unit conversion.

The assessed surface is high-risk. Remediate the findings before connecting.
Scanned 27 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 Utility Converter MCP server exposes 7 tools, focused primarily on general-purpose capabilities. Its published description reads: "Seven utility tools covering exchange rates, UUIDs, hashing, Base64, timestamps, and unit conversion". It communicates over Streamable HTTP using the 2025-06-18 protocol revision, and does not require authorization to connect. MCPGrade currently rates Utility Converter D — the assessed surface is high-risk and should be remediated before use. Its most notable findings include "Unguarded destructive tools" and "Command-execution tool takes a free-form command". 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 Utility Converter's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add Utility Converter to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.

tool: calculate
Tools that execute commands / write files / make arbitrary requests are exposed without annotations or guards.
alculate Safely evaluate an arithmetic expression and return the exact result. Supports +, -, *,RecommendationAnnotate destructive tools and require human approval.
tool: calculate
An exec/shell/run-code tool exposes a command/code/args parameter that is a free-form string with no enum/pattern guard — a direct command-injection / RCE surface. A tool constraining the command to an `enum` of allowed operations does not fire.
unconstrained command parameter "expression"RecommendationReplace the free-form command with a fixed `enum` of allowed operations (or structured, escaped arguments) and require explicit human approval.
tool: calculate_date
A tool description tries to alter the model’s use of another tool.
