What each one does
Sentry MCP
Sentry's MCP service is primarily designed for human-in-the-loop coding agents. Our tool selection and priorities are focused on developer workflows and debugging use cases, rather than providing a general-purpose MCP server for all Sentry functionality. It runs locally over stdio via the published package.
From the project's README.
Storybook MCP Addon
Welcome to the Storybook MCP Addon monorepo! This project enables AI agents to work more efficiently with Storybook by providing an MCP (Model Context Protocol) server that exposes UI component information and development workflows. It runs locally over stdio via the published package.
From the project's README.
