Status as of publication: this incident is active and unresolved. Details below reflect what’s confirmed as of the time of writing; the situation may have changed by the time you’re reading this.
One of the most widely used MCP (Model Context Protocol) servers in the creative-tooling ecosystem just had its GitHub account taken over — and as of this writing, the maintainer still doesn’t have it back.
The Post That Started It
On August 9, developer Siddharth Ahuja (@sidahuj) posted an urgent alert on X: his GitHub account had been compromised, and ownership rights to his repositories had been stripped away entirely. The affected projects include two significant pieces of AI-agent infrastructure:
- blender-mcp — an MCP server with more than 25,000 GitHub stars that lets AI agents and LLM clients control Blender, the popular open-source 3D modeling and animation suite
- ableton-mcp — a companion MCP server with over 2,600 stars, giving agents similar control over Ableton Live, a widely used digital audio workstation
“URGENT: My Github got hacked and all my ownership rights were stripped,” Ahuja wrote, tagging GitHub’s official account directly and asking for help. The post has since drawn hundreds of thousands of views.
It Got Worse Before It Got Better
In a follow-up post roughly five hours later, Ahuja reported that his own account had been suspended — while he watched, apparently helplessly, as commits continued to land on the hijacked repositories. “It seems that my account has been suspended while I see commit after commit by the hacker,” he wrote, again tagging GitHub and asking the company to escalate.
Community members, including at least one person claiming to be able to help coordinate with GitHub’s support team, responded asking Ahuja to share his support ticket number so they could follow up directly. As of this writing, Ahuja has not publicly confirmed that ownership has been restored, and the resolution timeline remains unknown.
What We Know — and What We Don’t
Here’s what’s been independently confirmed: the account takeover happened, ownership of both repositories was stripped from the original maintainer, and unauthorized commits continued to land on the affected repos after the takeover — including changes described as branding modifications and, notably, some security-hardening additions such as SSRF (server-side request forgery) blocks and a new SECURITY.md file.
Here’s what remains unconfirmed: the attack vector. It’s unclear whether this was phishing, a leaked personal access token, a compromised two-factor authentication method, or something else entirely. No backdoor or malicious payload has been confirmed as inserted into the codebase as of this writing — but that absence of confirmation is not the same as a clean bill of health, especially for a project this widely deployed.
It’s also worth being precise about sourcing here: this story is currently confirmed only through the maintainer’s own verified X account and subsequent public activity there. No mainstream press coverage has surfaced yet. That’s not unusual for a fast-moving security incident in its first hours, but it does mean some details — particularly around motive and full scope — should be treated as provisional.
Why a 25k-Star MCP Server Matters
If you’re not deep in the MCP ecosystem, it’s worth understanding why this particular repo is a meaningful target. MCP (Model Context Protocol) servers act as bridges between AI agents and real software — in this case, giving an LLM-driven agent the ability to actually manipulate objects, materials, and scenes inside Blender, or tracks and effects inside Ableton, rather than just talking about them.
That means blender-mcp sits in a privileged position in a lot of creative and agentic workflows: users trust it enough to let an AI agent execute commands inside a desktop application on their machine. A supply-chain compromise of a project like this — inserting malicious code that later gets pulled via git clone, pip install, or a package manager update — is exactly the kind of attack security researchers have been warning about as MCP adoption accelerates. Twenty-five thousand stars is a lot of downstream trust to have riding on a single maintainer’s account security.
The Bigger Pattern: MCP’s Growing Pains
This incident lands at an awkward moment for the broader MCP ecosystem, which has exploded in popularity as the de facto standard for connecting AI agents to real-world tools and applications. Rapid adoption has outpaced, in many cases, the kind of organizational-level security hardening that mature open-source foundations typically build — things like mandatory hardware-key two-factor authentication for maintainers, org-level protections against unilateral ownership transfers, and mirrored backups of critical infrastructure that make a single compromised account far less catastrophic.
Right now, there isn’t a clear industry consensus on what “secure MCP server maintenance” should look like at scale. Expect that conversation to accelerate once this incident — and others like it — settle enough for postmortems.
What to Do If You Depend on These Projects
Until Ahuja confirms restoration and the incident is formally closed out, users and integrators relying on blender-mcp or ableton-mcp should treat any commits made during the compromise window with heightened scrutiny. If you’ve pulled updates to either repository recently, it’s worth diffing against a known-good prior release before trusting new code, and watching Ahuja’s X account and the repositories themselves for an official all-clear.
We’ll be watching for updates on this story and will follow up once the situation resolves — including, if warranted, the account-security best-practices piece for MCP maintainers that this incident is already making a strong case for.
