Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Form U.S. companies and file U.S. trademarks. The agent prepares the filing and the owner signs it.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.
search_docsSearches OpenFile's docs and returns the best sections with a link to each.
read_docOne docs page as Markdown, by its slug.
plan_taskThe 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_pricingFormation packages, the trademark package, and USPTO fees.
quote_applicationEvery fee for a number of classes, with the government's marked. Saves nothing.
list_classesThe Nice classes small businesses file in most, with ID Manual style wording. Wording from this list avoids the USPTO free-form surcharge.
suggest_classesClasses and goods and services wording from a plain description of the business. Results are suggestions to confirm with the person.
screen_markChecks 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_marksSearches 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_alternativesNames that keep the idea of a risky mark. Each has passed the refusal screen and a USPTO search.
check_siteFrom a website or app store link: the brand, its legal owner, and which USPTO marks are theirs or someone else's.
read_siteWhat 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_typesEverything 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_typeOne 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_applicationSaves 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_applicationA draft, what's still missing, and the filing once the owner has signed.
update_applicationChanges the fields you send on a draft. Fails once the owner has signed.
list_statesEvery state with its filing fees for an LLC, corporation, limited partnership and LLP. fee_verified false means an estimate.
get_stateOne state's filing fees, annual report, accepted company name endings and publication rules.
list_servicesEvery add-on with its price, whether it can go on a formation, and whether the owner orders it from their dashboard.
quote_formationEvery fee for a formation, with the state's marked. Needs entity, state and package. Saves nothing.
create_formationSaves 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_formationA draft formation, what's still missing, and the order once the owner has signed.
update_formationChanges the fields you send on a draft formation. Fails once the owner has signed.
get_orderA signed formation's status, what the owner still has to do, and the state file number once formed.
get_filingA signed application's status, the attorney's note if there is one, and its USPTO serial number once filed.
add_specimenAdds or replaces the image showing the mark in use, until the attorney has filed. Sends a filing that needed changes back for review.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
The registry does not list a required key, though some servers ask you to sign in on first use.
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.
The GitHub repo last changed –, and the latest version (1.0.1) reached the registry today.
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 in developer mode.
