Patch Changes

0.4.1

Patch Changes

  • #172 a610073 Thanks @JReinhold! - Simplify package READMEs for docs-site-first documentation

0.4.0

Minor Changes

  • #185 c5439b7 Thanks @copilot-swe-agent! - Add MCP server-level instructions to both packages

    Both @storybook/mcp and @storybook/addon-mcp now include server instructions in the MCP initialize response. These instructions guide agents on how to use the available tools effectively without requiring explicit prompting from users.

Patch Changes

0.3.4

Patch Changes

  • #179 ec300bd Thanks @copilot-swe-agent! - Improve /mcp HTML response

  • #181 ff217d8 Thanks @copilot-swe-agent! - Rename feature flag experimentalComponentsManifest → componentsManifest

0.3.3

Patch Changes

  • #171 b3a8356 Thanks @copilot-swe-agent! - Fix: expose the get-documentation-for-story tool in the MCP Addon.

  • #176 8afbb72 Thanks @JReinhold! - Improve preview-stories tool description to make agent behavior more consistent.

  • #175 6a098f9 Thanks @JReinhold! - Add story ID based inputs for preview/testing workflows and surface story IDs in docs outputs.

    This change keeps existing path-based story inputs (absoluteStoryPath + exportName) while adding a storyId input shape for preview-stories and run-story-tests. It also adds withStoryIds to list-all-documentation and includes story IDs in get-documentation story sections, so agents can discover and reuse IDs directly without extra filesystem lookup steps.

  • Updated dependencies [b3a8356, 6a098f9]:

    • @storybook/mcp@0.5.0

0.3.2

Patch Changes

  • #131 9cf991c Thanks @JReinhold! - Added run-story-tests tool that is available when:

    1. @storybook/addon-vitest is configured
    2. Running Storybook 10.3.0-alpha.8 or above

    Additionally, if @storybook/addon-a11y is configured, the tool returns accessibility violations too.

  • #141 03e957d Thanks @shilman! - Upgrade deprecated MCP server methods

  • #160 bab8ec9 Thanks @JReinhold! - Render component-attached MDX docs entries in markdown output for get-documentation.

    This fixes a regression where docs attached to components via component.docs in components.json were not included in markdown responses. The markdown formatter now emits a ## Docs section below stories (and before props).

  • Updated dependencies [b7aeb40, bab8ec9]:

    • @storybook/mcp@0.2.2
