Trust AssessmentAI Assessment

@storybook/addon-mcp is an MIT-licensed Storybook addon published via GitHub Actions that runs an MCP server to help AI agents automatically generate and test UI component stories. The service shows low operational risk with zero known vulnerabilities, full uptime, and active maintenance across its 6 dependencies. Adoption remains relatively low at 248K weekly downloads, and transparency is moderate, which is typical for specialized development tooling in the early stages of the Model Context Protocol ecosystem.
