Advertising policy
Paid placements keep MCPVault independent, but they never get to make it worse. Every sponsor creative is reviewed by a human before it appears anywhere on the site, every placement is labelled SPONSOR or FEATURED, and grades, rankings and verification results are never for sale.
MCPVault serves developers choosing tools for AI systems. Placements should be relevant to that audience. Products with no connection to software development or AI tooling are reviewed with extra skepticism and are usually declined.
How review works
Checkout is self serve and payment comes first: paying reserves your slot immediately. Your creative (logo, name, tagline and link) is then reviewed before it is displayed, normally within 24 hours. If we cannot approve your placement under this policy, we cancel the subscription and refund the payment in full. You never pay for a placement that never ran.
If only the creative is the problem, for example a tagline that overclaims, we tell you exactly why and you can fix and resubmit from your account page. The slot stays yours while you do.
What we do not accept
Political content
Campaigns, advocacy, political organizations or messaging of any leaning.
Discriminatory content
Anything that targets or demeans people based on who they are.
Violence and shocking content
Violent, graphic or intentionally disturbing material.
Adult content
Pornographic or sexually explicit products and imagery.
Malware and deceptive software
Malware, spyware, stalkerware, or software that misrepresents what it does.
Scams and misleading claims
Get-rich-quick schemes, fake urgency, income promises, or claims a product cannot back up.
Health products and claims
Supplements, vitamins, pills, medical devices, treatments, or any health claims. This is a developer directory, not a pharmacy.
Gambling
Casinos, betting, lotteries and adjacent products.
This list is not exhaustive. We decline anything we would not stand behind in front of the developers who trust this directory, and our decision is final.
Creative rules
Sponsor placements are structured, not banner ads: a square logo, a company name, a short tagline and a link, rendered in the MCPVault design system. Taglines must describe what the product actually does, in plain language, without superlatives you cannot prove. Links must go over https to the page the tagline describes, with no redirect chains and no bait and switch.
Removal and refunds
If a live placement turns bad, for example a product pivots into a category above or a link starts redirecting somewhere new, we remove the placement, cancel the subscription and refund the unused part of the period. Sponsors can cancel any time from their account page and the placement stays live until the end of the paid period.
Pricing changes
Placement prices may be adjusted over time, always with notice in advance. A price change only ever applies from your next renewal: the price you paid for the current period is locked until that period ends, and nothing changes mid period. If you do not accept a new price, cancel before renewal and your placement runs out the period you already paid for.
