Arcade.dev Acquires Smithery, Merging MCP Registry with Execution Layer
Arcade.dev has acquired Smithery, a public registry for MCP servers, merging discovery with Arcade's execution and authorization layer. The deal, announced August 5, combines Smithery's catalog of tens of thousands of entries with Arcade's secure action layer, which handles delegated authorization and audit logging. Financial terms were undisclosed, and Smithery co-founder Anirudh Kamath joins Arcade. The acquisition raises questions about registry neutrality and grading independence, as Arcade also runs ToolBench, its own benchmark for MCP server quality.
