Available tools 9

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

styles
styles_get_component
Return the real CSS styling surface of a DWC web component: CSS custom properties, shadow parts, reflected attributes, and slots. Accepts a DWC tag ("dwc-button") or a webforJ Java class name ("Button", "TextField"). Use mode="list" for every valid tag, mode="map" for Java -> tag mappings. Call this before writing CSS for a component so you never guess a var or part name. Prefer a typed Java setter on the component over CSS when both can produce the same result.
styles_list_tokens
Return the authoritative list of global --dwc-* tokens (palette seeds, color shades, surfaces, spacing, typography, borders, etc.). Use this for any "which tokens are available for X" question — DO NOT ask the knowledge base to list tokens; it returns prose and the answer will be hallucinated. Filter with "prefix" (e.g. "--dwc-color-primary-") or "contains" (e.g. "seed") to narrow the result. For component-scoped CSS vars like --dwc-button-* use styles_get_component instead. The returned list is verbatim and complete for the filter you passed — do not add, rename, complete, or explain "implied" tokens, and do not reference tokens from other webforJ versions. If a token you expect is missing from the response, it does not exist for that version. Tokens that share a description are returned in a single entry where "names" is the list of every token that has that description; treat each name as a real, independently usable token. When writing CSS, use a token instead of hardcoding colors, spacing, or font sizes.
styles_validate_tokens
Validate every --dwc-* reference in CSS, Java, MDX, or Markdown text against the real DWC global tokens and component CSS variables. Returns the list of invalid tokens with line numbers and ranked similar-name suggestions. Run this on any generated or edited stylesheet before writing it to disk.
document
get_document
Return the full content of an indexed webforJ documentation or sample file. Use this as a follow-up to search_knowledge_base when a search result excerpt is not enough and you need the complete page — migration guides, tutorials, long API docs. Pass the documentId from a search result.
fqcn
fqcn_validate
Validate fully qualified class names against the catalog of types declared in webforJ source for the target version. Accepts either an explicit list of FQCNs or a Java snippet (the handler extracts its import statements). Returns unknown FQCNs with ranked similar-name suggestions. FQCNs outside the webforJ package family are not validated. Run this on any generated or edited Java before writing it to disk.
knowledge
search_knowledge_base
Search webforJ documentation, JavaDoc, and code samples for any class, method, annotation, or component, and for CSS styling concepts and rules (palette semantics, seed vs h/s, :not([theme]) pattern, dark mode, ::part limits, table styling). Returns matching snippets with titles, categories, and relevance scores. Call this before claiming any webforJ API exists. For exact --dwc-* custom property or ::part() names on a specific component, use styles_get_component instead; to verify tokens in generated CSS, use styles_validate_tokens. Pass category to narrow the search; if the category is unknown the tool errors with a ranked list of similar names plus the full set of valid categories, so you can retry. In a webforJ project the deliverable is Java (or the Kotlin DSL) using webforJ classes; search for the dedicated webforJ component before falling back to React, JSX, or hand-built HTML.
project
create_project
Returns the Maven archetype command that scaffolds a new webforJ project, plus the follow-up commands to change into the generated directory and start the dev server. Relay the Maven command to the user via the host shell tool without modifying its arguments. Set showOptions=true to list available archetypes and the startforJ web generator instead of producing a command.
theme
create_theme
Generate a webforJ theme from a primary HSL color. Returns two content blocks: a JSON summary with theme metadata, @AppTheme / @StyleSheet snippets, and recommended file paths, plus a second text block prefixed "CSS_CONTENT:" containing the full stylesheet.
versions
get_versions
Report the webforJ versions this server knows about. Returns the latest stable release, the current in-development SNAPSHOT (from the main-branch pom.xml), and an array of every major with its highest observed tag plus a `status` flag: "development" (the active SNAPSHOT line — actively changing), "stable" (the latest released major — may still receive minor/patch bugfixes), or "frozen" (older released majors — no new releases will be cut). Each major also carries `dataAvailable` indicating whether the DWC styling tools can answer questions about it. Call this FIRST when you do not know what version the user is on or which version to target — never guess.

webforJ MCP Server — questions

Answers built from our own checks of this server.

What can webforJ MCP Server do?
It exposes 9 tools, read directly from the server on our last check. Among them: create_project, create_theme, fqcn_validate, get_document, get_versions, search_knowledge_base and 3 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is webforJ MCP Server working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 182 checks got a reply (50.0%), average response time 159 ms. The bar chart above shows every period we have measured.
How do I connect webforJ MCP Server?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does webforJ MCP Server need an API key?
No. webforJ MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is webforJ MCP Server?
It answers our handshake in 159 ms on average, which is faster than 71% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
