Tools & capabilities
Melta UI tools 6
get_tokenGet a design token by dot-path. Returns the token object with its value and class mapping.get_componentGet component metadata including variants, sizes, accessibility requirements, HTML sample, per-state specs (stateSpecs: disabled/loading/open/empty etc. — each with delta class strings + aria changes), and anatomy parts (overlay/container/th etc. with element/roles/class). Prefer these structured fields over inferring states from the HTML sample.check_ruleCheck class strings against this design system's prohibition rules. Returns violations with reasons and alternatives.check_htmlLint a full HTML/JSX source against melta-ui rules — the same checks as CI and the PostToolUse hook (class rules + html-attr rules + composition rules for HTML). Use this AFTER generating UI code to self-verify before presenting it. Response always includes coverage info (manual rules cannot be auto-checked).searchSearch across tokens and components by keyword. Matches against names, values, class strings, and descriptions. Returns up to 20 results (truncated flag when more matched).get_rulesGet melta-ui prohibition rules from rules.json (107 total). Use this to retrieve manual/contextual rules that check_rule cannot auto-detect. Supports filtering by category, severity, or detector.
PDFGate MCP Server tools 24
generate_pdfGenerate a PDF from a URL or raw HTML. Provide either 'url' or 'html', not both.upload_fileUpload a PDF to PDFGate so it can be referenced by other operations. Provide either 'filePath' (local path) or 'url'.get_documentRetrieve metadata for a stored PDFGate document by its ID.delete_documentDelete a PDFGate document.flatten_pdfFlatten an interactive PDF into a static, non-editable PDF. Creates a new document; does not overwrite the original.extract_form_dataExtract form field values from a fillable PDF. Returns a JSON object mapping field names to their values.add_form_fieldsAdd interactive form fields to a stored PDF — from placeholder tags (refined via fieldOverrides) and/or explicitly positioned fields.compress_pdfCompress/optimise a PDF to reduce file size without changing visual content.protect_pdfEncrypt a PDF with a password and optional permission restrictions. Produces a new document; the original is unchanged.watermark_pdfApply a text or image watermark to a PDF. For type='text' provide 'text'; for type='image' provide 'watermarkImagePath'.download_fileDownload the raw PDF bytes of a stored document, returned as an embedded resource. For a shareable link instead, use get_document.create_envelopeCreate a signing envelope from one or more existing PDFGate documents. Each recipient is given either as email and name or as the recipientId of a stored recipient. Recipients marked embedded sign inside your application via create_embed_link and receive no emails. Use signingOrder to make recipients sign in sequence. Returns an envelope in 'created' status; call send_envelope to dispatch signing emails.- +12 more on the listing page
