Corporate Espionage or Fair Competition? Runlayer Sues Rippling Over MCP Protocol Access
AI infrastructure startup Runlayer has initiated legal action against HR giant Rippling for allegedly cloning its Model Context Protocol gateway. The complaint follows a year-long collaboration that Runlayer claims was a front for intellectual property theft.
A legal battle has erupted in the burgeoning sector of AI interoperability. Runlayer, a startup specializing in secure Model Context Protocol (MCP) gateways, filed a lawsuit against HR software firm Rippling, alleging that the latter weaponized a trial period to misappropriate trade secrets. The complaint, reviewed by TechCrunch, outlines a narrative of prolonged technical intimacy followed by a sudden competitive turn.
The Long Trial and the Alleged Betrayal
In mid-2023, Runlayer, which has secured $42 million in funding from investors like Khosla Ventures and Felicis, entered into an extensive evaluation phase with Rippling. According to the court filing, this engagement lasted nearly one year and involved deep engineering collaboration. Under the protection of a mutual non-disclosure agreement and a specific product trial contract, Runlayer provided Rippling with extensive access to its internal systems, including:
- Detailed product roadmaps outlining future innovations.
- Access to proprietary source code and architectural designs.
- Direct consultation on the implementation of MCP security layers.
Discussions reportedly collapsed when the two entities failed to reach a pricing agreement, leading Runlayer to terminate the evaluation. The lawsuit claims that shortly thereafter, an internal source at Rippling contacted Runlayer CEO Andrew Berman via text, warning him that Rippling was developing a project described as nearly a 1-to-1 clone of Runlayer’s software.
Market Pressure and Legal Maneuvers
Rippling has confirmed it is launching its own MCP gateway but denies all allegations of IP misuse. A spokesperson for the company characterized the lawsuit as a "panicked effort" to stifle competition and insisted their product relies entirely on proprietary information. However, Runlayer has signaled its intent to fight by retaining Sullivan & Cromwell, a prestigious law firm whose involvement adds significant weight to the litigation.
The Risk of the 'Build vs. Buy' Dilemma
This dispute highlights a growing tension for AI infrastructure providers selling to tech-heavy enterprise clients. These customers often possess the engineering resources to replicate tools they initially seek to purchase. When Anthropic released MCP as an open-source standard in November 2024, the market for gateway products became increasingly congested. The case serves as a warning for startups whose survival depends on sharing sensitive intellectual property during lengthy sales cycles with potential competitors.
Runlayer’s claims include breach of contract, unfair competition, and trade secret misappropriation. The outcome will likely hinge on whether Rippling can prove its solution was developed independently of the insights gained during the year-long technical deep dive.
