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 bikefuchs MCP server exposes 7 tools, focused primarily on general-purpose capabilities. Its published description reads: "Price comparison & cart optimizer for bike parts across German & Austrian shops". It communicates over Streamable HTTP using the 2025-06-18 protocol revision, and does not require authorization to connect. MCPGrade currently rates bikefuchs F — a critical issue was found and the server should not be connected as-is. Its most notable findings include "Cross-tool shadowing" and "Cross-tool shadowing". 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 bikefuchs's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add bikefuchs to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.

Search for bicycle parts, components, accessories, and cycling clothing by name, brand, or model number. Returns matching products sorted cheapest-first, each with its price, stock status, EAN barcode
Look up a single product by its EAN barcode and return the price at every shop that carries it, sorted cheapest-first, with stock status and direct purchase links.
Find the cheapest way to buy multiple products together: computes the optimal split across shops — which items to order from which shop — accounting for each shop's shipping costs and free-shipping th
Return an overview of the supported shops, including their shipping cost tiers, free-shipping thresholds, and supported countries (DE and AT).
Return the exact shipping cost for a specific shop, country, and cart value, including all shipping tiers and how much more is needed to reach the next free-shipping threshold.
Given a product's EAN barcode, return every shop that carries it with prices and availability, sorted cheapest-first.
Turn a product page URL from a supported shop into structured product data — EAN barcode, price, stock status, and a purchase link — so the EAN can then be used with get_best_price or optimize_cart. M
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.
