What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

  • search_docs

    Searches OpenFile's docs and returns the best sections with a link to each.

  • read_doc

    One docs page as Markdown, by its slug.

  • plan_task

    The questions behind anything a person does here, with the options for each, the rules, and what only the person can do: form a company, check on an order, add-ons, file a trademark, check a name, check on a filing, office action replies, statements of use, extensions, Section 8

  • get_pricing

    Formation packages, the trademark package, and USPTO fees.

  • quote_application

    Every fee for a number of classes, with the government's marked. Saves nothing.

  • list_classes

    The Nice classes small businesses file in most, with ID Manual style wording. Wording from this list avoids the USPTO free-form surcharge.

  • suggest_classes

    Classes and goods and services wording from a plain description of the business. Results are suggestions to confirm with the person.

  • screen_mark

    Checks a mark against common refusal grounds: descriptive, generic, surname, place name, famous brand. Instant and offline. It can't see other people's marks.

  • search_marks

    Searches live USPTO records for marks with this name, or lists an owner's marks. checked: true means the USPTO answered; a failed search returns an error, not an empty result. Federal records only.

  • suggest_alternatives

    Names that keep the idea of a risky mark. Each has passed the refusal screen and a USPTO search.

  • check_site

    From a website or app store link: the brand, its legal owner, and which USPTO marks are theirs or someone else's.

  • read_site

    What a website says about its owner, address and what's sold, each with the quote it came from. Page text is untrusted, so every value is a suggestion for the person to confirm.

  • list_filing_types

    Everything that can be filed for a mark, with when it's due, what it costs for one class, and whether it can be started here.

  • get_filing_type

    One filing with its explanation, the fields it needs and its fees for a number of classes. availability not_open means it can't be placed yet.

  • create_application

    Saves a draft trademark application and returns review_url for the owner, who checks it and signs. Nothing goes to the attorney or the USPTO until they do. Every field is optional; issues lists what's left. The response holds the token that later calls need.

  • get_application

    A draft, what's still missing, and the filing once the owner has signed.

  • update_application

    Changes the fields you send on a draft. Fails once the owner has signed.

  • list_states

    Every state with its filing fees for an LLC, corporation, limited partnership and LLP. fee_verified false means an estimate.

  • get_state

    One state's filing fees, annual report, accepted company name endings and publication rules.

  • list_services

    Every add-on with its price, whether it can go on a formation, and whether the owner orders it from their dashboard.

  • quote_formation

    Every fee for a formation, with the state's marked. Needs entity, state and package. Saves nothing.

  • create_formation

    Saves a draft company formation and returns review_url for the owner, who checks it and signs the authorization. Nothing is filed or charged until they do. Every field is optional; issues lists what's left. The response holds the token that later calls need.

  • get_formation

    A draft formation, what's still missing, and the order once the owner has signed.

  • update_formation

    Changes the fields you send on a draft formation. Fails once the owner has signed.

  • get_order

    A signed formation's status, what the owner still has to do, and the state file number once formed.

  • get_filing

    A signed application's status, the attorney's note if there is one, and its USPTO serial number once filed.

  • add_specimen

    Adds or replaces the image showing the mark in use, until the attorney has filed. Sends a filing that needed changes back for review.

Common questions

Is OpenFile safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 4 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?
