Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 121 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name webforj-mcp.

  • Pass
    Lists tools

    tools/list returned 9 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 121 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 121 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    42 of 42 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Fail
    Website matches publisher

    The website host does not match the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Fail
    Recently updated

    Updated 2025-11-13T09:25:39.581042Z, which is older than 180 days.

  • Not measured
    Open-source licence

    No GitHub repository to ask about a licence.

Capabilities

Tools 9

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.

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
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.
