Comprehensive Model Context Protocol server for managing Home Assistant through AI assistants.
Nothing to run from here
Wenmar Open is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http wenmar-open-mcp https://open.wenmarpro.com/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
6 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Decode vehicle identification numbers into year, make, model, trim, engine, drivetrain, safety equipment and the matching catalog entry. action=decode takes vin (and optionally year to override the model year). action=batch takes vins, at most 50, and returns one result per VIN in order. A wrong check digit is not an error: the result has valid=false and a warning. action=overview takes `vin

Recall campaigns from NHTSA (United States) and Transport Canada that may apply to a vehicle. A campaign lists a year, a make and a model, so every answer has may_apply: true. It may apply; confirm by VIN with the manufacturer, or at the addresses in lookup. This is never a lookup by VIN. action=vehicle takes id, a vehicle id such as "2018_ford_f-150". action=vin takes vin (and optionally `y

Manufacturer communications NHTSA publishes: service bulletins, service campaigns, warranty extensions and over-the-air updates. Each has NHTSA's summary, the manufacturer's own document number, and document, the address NHTSA's copy of the document is expected at (not confirmed; null for old ones). The document itself is the manufacturer's and is not returned. A bulletin lists model years: it i

Generic OBD-II trouble codes, described in Wenmar Open's own words: a title, what the code means, common causes, first checks, the components it concerns and related codes. Only codes every maker uses the same way are described (P0, P2, P3400 and up, B0, C0, U0, U3). Manufacturer-specific codes are not described. action=get takes code, such as "P0420", and gives its description. action=search li

Wenmar's own estimates of the hours a repair job takes: written by people who do the work and later measured from repair orders, never from a labour guide. An estimate, not a quote. Rust, seized fasteners and added equipment change the time. action=jobs lists the jobs an estimate can be about; with job it gives one job: what it includes, what it excludes, and its typical hours by class of vehicl

No rule-by-rule report on file for this release
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 0.2.0.

One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Wenmar Open can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
