Bestax

bestax-mcp

The official MCP server for @allxsmith/bestax-bulma — React components for Bulma v1.

It gives a coding agent the whole library: every component's props (including compound sub-parts like Navbar.Brand), ~900 working examples, the --bulma-* CSS variables behind every component, the helper props that replace inline styles, and the bestax Agent Skills as invocable prompts.

Offline and version-pinned. The index ships inside the package — no network calls, nothing to rate-limit. It documents one specific bestax-bulma release, and the server checks the version actually installed in your project and warns you when they disagree, rather than confidently describing props you do not have.

Setup

Each release is published to the official MCP Registry as io.github.allxsmith/bestax-mcp, for clients that install from it.

Claude Code

claude mcp add bestax -- npx -y bestax-mcp@1

Or install the bestax plugin instead. It runs this same server and adds the bestax Agent Skills:

/plugin marketplace add allxsmith/bestax-skills
/plugin install bestax@bestax

Cursor, Claude Desktop, Windsurf, Cline

Add to your MCP config (.cursor/mcp.json, claude_desktop_config.json, …):

{
  "mcpServers": {
    "bestax": {
      "command": "npx",
      "args": ["-y", "bestax-mcp@1"]
    }
  }
}

The server checks your installed @allxsmith/bestax-bulma against the version it documents, looking for it from the directory it starts in. If your client starts servers somewhere other than your project, point it at the project with BESTAX_MCP_PROJECT_DIR in the config's env:

{
  "mcpServers": {
    "bestax": {
      "command": "npx",
      "args": ["-y", "bestax-mcp@1"],
      "env": { "BESTAX_MCP_PROJECT_DIR": "/path/to/your/project" }
    }
  }
}

If it finds no installed copy, its first answer says so.

The @1 pins the major version. Without it, npx resolves whatever is newest on every launch — so a breaking change, or a compromised release, reaches your agent the next time it starts, with no review step. Add it to your dev dependencies instead if you would rather your lockfile decide.

Tools

Start with list_components — its output names the tool to call next. Reach for search_bestax when you need a component whose name you do not know.

Tool	What it gives you
list_components	Every component with a one-line purpose, by category
search_bestax	Components, props, examples, CSS variables and skills in one ranked list
get_component	Import, summary and props; optionally examples, CSS variables, accessibility, related
get_props	One prop table, including compound sub-paths (Navbar.Brand)
get_examples	Working tsx examples from the component's docs page
get_css_variables	The --bulma-* custom properties a component reads, with Sass names and defaults
get_helper_props	Spacing, colour, typography, flexbox and visibility props — call this before writing an inline style
lookup_bulma_classes	The bestax component and props for a Bulma class string (button is-primary), one row per class
list_skills	The seven bestax Agent Skills
get_skill	A skill's instructions, or one of its reference documents

Prompts

One per skill, so a task can start from the library's own guidance: custom-component, form, theming, layout-scaffold, icons, migrate, optimize.
