Arcade.dev has acquired Smithery, the prominent public registry and hosting platform that emerged as the premier destination for developers to discover and deploy Model Context Protocol (MCP) servers. The acquisition, announced on August 5, includes the integration of Smithery co-founder Anirudh Kamath into the Arcade team. While financial terms remain undisclosed, the strategic move signals a major shift in how enterprises manage AI agents.
Consolidating the AI Agent Ecosystem
As enterprises transition AI agents from experimental pilots to production environments, the demand for robust infrastructure has surged. Organizations require a unified ecosystem that combines a comprehensive tool catalog with a secure runtime capable of auditing and authorizing agent actions. By merging Smithery’s discovery capabilities with Arcade’s execution layer, the acquisition aims to provide a single, end-to-end solution for CIOs.
Bridging Discovery and Execution
Smithery built its reputation by solving the “discovery and packaging” bottleneck, allowing developers to locate and run servers with minimal friction. This utility drove the index to tens of thousands of entries, encompassing both MCP servers and Anthropic’s Agent Skills format. Arcade, conversely, operates as a secure action layer. By managing delegated authorization, Arcade ensures that agents act only with specific user permissions, while simultaneously generating a comprehensive audit trail for every action taken.
The Ambition Behind the Buy
Arcade is positioning itself as the backbone of agentic infrastructure. Following a $60 million Series A round in June led by SYN Ventures—bringing total funding to $72 million—the company has the capital to back its aggressive expansion. Arcade claims to have authored the MCP authorization specification, a standard now widely referenced by major clients and servers, further cementing its influence over the protocol.
Benchmarking and the Quality Gap
The rationale for the acquisition is rooted in Arcade’s data-driven approach. Through its ToolBench benchmark, Arcade has analyzed over 219,000 tools across 43,400 MCP servers. The findings were stark: only 0.5% of these tools earned an “A” grade. Arcade attributes this to a “publishing gold rush” where the speed of releasing new tools has significantly outpaced the rigors of engineering, resulting in malformed schemas and overlapping tool names that often cause model failures.
The Evolving Competitive Landscape
Arcade now operates in a space crowded with diverse approaches to protocol management. The official MCP Registry, launched in preview in September 2025, serves as a thin, community-owned source of truth. Meanwhile, Docker has prioritized containerization and policy enforcement within its own MCP Catalog and Toolkit. Furthermore, the protocol’s governance has shifted to the Agentic AI Foundation under the Linux Foundation, with support from industry giants like OpenAI, Google, Microsoft, and AWS.
Addressing Neutrality and Future Risks
The acquisition raises valid questions regarding developer trust and platform neutrality. Developers previously favored Smithery for its independence, but now the registry is controlled by a vendor with a commercial incentive to prioritize its own runtime. Arcade has yet to publicly clarify how it will insulate its grading and verification processes from its commercial interests.
Additionally, the rapid evolution of the MCP protocol—including breaking changes like the removal of initialization handshakes—creates a volatile environment for registries. For platform teams, the move toward Arcade necessitates a critical evaluation of three key areas:
- Portability: Determining whether authorization policies and audit records can be exported or if they remain locked within a single vendor’s control plane.
- Grading Independence: Ensuring that ToolBench scores remain objective, especially when evaluating servers that compete directly with Arcade’s own catalog.
- Scalability Costs: Assessing how pricing models adjust during periods of high tool-call volume, a metric that Arcade reports has grown 25-fold in the last six months.
Ultimately, the era of assembling MCP tooling from disparate, free parts is ending. As the technology matures into a procured enterprise layer, Arcade’s acquisition of Smithery represents a strategic move to dominate the entire lifecycle of agentic execution.
