Trust breakdown (7 categories)

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →

Endpoint Security74
Transport & Reachability100
Schema Quality & AI Usability71
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 898 tokens (~179/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
  • Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage96
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 88% of tool parameters carry a description.Partial
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a current MCP spec version (2026-07-28).Pass

Unverified: 1 category

A category scored 0 because we could not verify it: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

Install

How do I install the Rack Warehouse fitment MCP server?

Rack Warehouse fitment is a hosted endpoint at https://mcp.rackwarehouse.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 5 exposed · ~637 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
check_fit ~172

Whether one product fits one vehicle: 'yes' with the fit options and the price and page for the vehicle, 'not listed', or 'by what it mounts to' for carriers. Also what the product needs (crossbars, a hitch, required parts) and what checkout will ask. The product is its rackwarehouse.com page URL, its handle or its SKU.

NameTypeReqDescription
makestringyesMake handle or name, e.g. toyota (find_vehicle gives it)
modelstringyesModel handle or name, e.g. corolla
productstringyes–
roof_typestring–e.g. Naked Roof, Raised Rails, Flush Rails, Fixed Point, Tracks, Gutter
yearinteger–Model year, e.g. 2018

No output schema declared.

No examples provided.

find_vehicle ~61

Turn the shopper's words ('2019 tacoma', 'subaru outback') into vehicles Rack Warehouse has fitment for, with the roof types each can have. Use the make and model it returns with the other tools.

NameTypeReqDescription
querystringyes–

No output schema declared.

No examples provided.

get_product ~85

One product as its page shows it: price and sale, availability, variants, specs, summary and highlights, what a rack system includes, what it mounts to, required products, what checkout asks, rating and reviews, and its page. It does not list vehicles: use check_fit for one.

NameTypeReqDescription
productstringyesIts rackwarehouse.com page URL, handle or SKU

No output schema declared.

No examples provided.

search_products ~137

Search Rack Warehouse's catalog the way the site's search box does: up to eight products for the shopper's words, optionally within a category, a brand and a price ceiling, each with its price, review count, how it fits (by vehicle, or by what it mounts to) and its page.

NameTypeReqDescription
brandstring–Brand name, e.g. Thule
categorystring–Category handle, e.g. bike-racks
max_pricenumber–Highest price in US dollars
querystring–The shopper's words, e.g. 4 bike hitch rack for e-bikes

No output schema declared.

No examples provided.

what_fits ~182

What fits one vehicle. Without a category: how many products fit, by category, and the category handles to ask with. With a category: up to eight products, each with its fit for this vehicle, its price for this vehicle and its page; carriers that mount to crossbars or a hitch come back with what they mount to and the base racks for the vehicle.
