To get your product into the Grok Bot marketplace, fill in xAI's form at x.ai/bot/marketplace/submit-a-plugin. xAI, the company behind the Grok assistant, uses that one form to list a plugin in three places: Grok Bot, the Cursor code editor, and Grok itself, which the form marks as coming soon. What you submit is your MCP server, the connector that lets an AI agent read from and act in your product (MCP stands for Model Context Protocol, the open standard most assistants now support).
Submit it now, because the agents are already choosing tools. This month I asked Grok Bot to check search volumes, and it offered me Ahrefs on its own, with a verified badge and an Authorize button, although my account with DataForSEO, another SEO data provider, was already connected and had been used several times. I had to tell it to use the account I have credits on, and wrote about it on LinkedIn. Ahrefs has a verified plugin in the marketplace Grok Bot draws from, and DataForSEO has none.
One session says little about how Grok Bot ranks tools, and Ahrefs is also the better-known brand. The listing is still the part of that choice a vendor can do something about, and the review behind it takes weeks. The Ahrefs plugin was also built by Cursor itself, which means a marketplace will sometimes list your product for you. Submitting your own plugin is how you decide what it says.
Most AI labs now run a catalog
Most labs that ship an assistant now keep a catalog of tools their users can add from inside the product:
- Anthropic lists connectors and plugins in the Claude directory.
- OpenAI lists apps in the ChatGPT apps directory.
- Microsoft lists agents in the Microsoft 365 Agent Store, submitted through Partner Center.
- xAI lists plugins in the Grok Bot marketplace, and keeps a separate Grok Build marketplace on GitHub for its coding agent.
- Meta is taking early-access applications for Meta AI Connectors.
Google is the exception so far: we found no open directory for third-party connectors in the Gemini app. Each catalog has its own form, account requirements and review. We keep them, along with the independent sites that index MCP servers, in our list of 47 places to submit an MCP server, with what each one asks for.
A listing lets users find you where they already work and connect you without leaving the assistant. And when an agent goes looking for a tool to do a job in your category, your plugin is one it can choose and call, alongside whatever a competitor has listed.
Software directories like G2 and Capterra still shape whether an assistant thinks of your product for a job, because that is where it reads about you. The catalog listing is what lets it act on that thought.
Grok Bot, Cursor and Grok share one marketplace
Grok Bot, launched on 11 August 2026, runs always-on agents, each with its own cloud computer. A bot signs into the tools you already use, runs multi-step jobs, and takes messages the way a coworker would, including in group chats. It is in beta on macOS and iOS and comes with SuperGrok, xAI's paid Grok subscription, and with Cursor's Pro, Pro+, Ultra and Teams plans.
SpaceX, which merged with xAI in February 2026, completed its acquisition of Cursor in August. Grok Bot's plugin documentation lives on cursor.com. In this marketplace, a plugin is a small package that tells the client where your MCP server lives and how to connect to it.
Before you start: what you agree to
Clicking Submit Plugin accepts the Cursor Marketplace Publisher Terms, last updated in May 2026. Read four of them before you fill anything in, because two can rule a plugin out:
- Open-source parts must use a permissive licence. Permissive licences such as MIT, BSD and Apache 2.0 let anyone reuse the code, including in closed products. Copyleft licences, which require anyone reusing the code to open-source their own (GPL, AGPL, LGPL), are not allowed. Cursor's plugin documentation also describes marketplace plugins as open source. The Terms do not address the code of a hosted server a plugin points at.
- Users cannot be charged for the plugin, in the Terms' words "directly or indirectly". If your plugin only works with a paid account, check that setup against the text.
- Approval is at Anysphere's sole discretion. Anysphere is the company behind Cursor. It verifies identity and business legitimacy before approving.
- You license your name and logo for promotion. The licence is non-exclusive, and you keep ownership.
Every update to a listed plugin goes through review again, so submit the version you want listed.
How to fill in the form
Every field except Website URL is required.
| Field | What to put there |
|---|---|
| First name, last name, work email | A person who reads that inbox. Cursor staff say marketplace follow-ups come by email, with no status page. |
| Organization name | Your company name as buyers know it. |
| Organization handle | Lowercase, no spaces. Use the brand name buyers search for. |
| Website URL | Optional. Fill it in anyway, so a reviewer can see who you are. |
| Logotype URL | A public link to a square (1:1) SVG or PNG on a solid background plate. A transparent logo does not meet the brief. |
| Where do you want to be listed? | Grok Bot, Cursor, and Grok (coming soon). Tick all three unless your server only makes sense in a code editor or only in a general assistant. |
| MCP server URL or public GitHub repository | The public URL your server runs at, or a public repository holding the plugin. |
| Brief description | What a user can ask the agent to do with your product, in plain language. |
| Testing instructions | How a reviewer gets in: a populated test account set aside for review, the sign-in steps, and three or four prompts that exercise your main tools. |
| Tested checkbox | Confirms you ran the plugin locally and inside the app. Do both before ticking it. |
Write the description around jobs. Name what the server does ("pull keyword rankings for a domain", "find open invoices over 30 days"). Do the same in your server's own tool descriptions, which are what an agent reads when it decides which tool to call. OpenAI's guidance for ChatGPT plugins says ChatGPT decides when to call a tool based on the metadata you provide. Keep the wording consistent with how your website and your directory listings describe the product, because an assistant reads all of them.
Make the testing instructions work for months. A reviewer may reach your submission weeks after you send it, so the test account, its data and its password need to still work then.
Expect a long review
The form states no review time. A product we work with submitted its MCP server to four catalogs on 1 October 2026. The ChatGPT listing went live on 23 October and the Claude listing by 3 November. The Cursor Marketplace submission and the Grok Build pull request were both still waiting on 9 November, more than five weeks later.
Other developers report the same. Submissions on the Cursor forum have sat unanswered for a month or more, and when asked in October, Cursor staff said they could not give an exact timeline.
While you wait, publish to the official MCP Registry, the public index of MCP servers run by the protocol's maintainers. You prove you own your domain or GitHub name, publish with its mcp-publisher tool, and the listing is live at once. Several independent MCP catalogs pick up new entries from it.
FAQ
Does one submission list me in both Grok Bot and Cursor?
Yes. Tick Grok Bot, Cursor and Grok on the form, and the Cursor Marketplace Publisher Terms cover all three.
Do I need to open-source my product?
The Publisher Terms require any open-source parts of the plugin to carry a permissive licence, and Cursor's documentation describes marketplace plugins as open source. One common setup is a small public repository holding the plugin manifest, which points at a hosted MCP server. The Terms do not address the hosted server's code.
How long does approval take?
xAI has published no figure. In our experience, catalog reviews take from about three weeks to more than five, and Cursor's has been the slowest.
Is this the same as the Grok Build marketplace?
They are separate. Grok Build, xAI's coding agent, uses its own plugin marketplace on GitHub, where you submit by pull request, a proposed change to the repository.
