Which MCP Server Should You Choose?
Choose Cleanor MCP when:
You need dedicated capabilities in the Multimedia Process domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Zero-auth hosted server with 22 read-only tools: optimize/convert images (WebP/AVIF/JPEG), paste-ready SVG QR codes, cited Cleanor Labs data on device storage capacity and next-gen image-format savings (AVIF/WebP/JPEG XL vs JPEG, HEIC conversion tax), plus 18 deterministic dev utilities LLMs get wrong (hash, HMAC, UUID, base64, JWT decode, JSON, regex, cron, unit & base convert, datetime, URL parse, diff, color, palette, slugify, count, SVG placeholder). No API key or signup; Streamable HTTP at https://mcp.cleanor.app/mcp.
Generates app icons, favicons, OG images, logos, and wordmarks. Routes each request across 30+ image models. Runs without an API key via Cloudflare Workers AI, NVIDIA NIM, HuggingFace, or Stable Horde. Three modes: inline SVG, external prompt-only, or full API. Validates contrast, OCR text accuracy, and palette before returning.
Tools & Capabilities Breakdown
Cleanor MCP Tools (22)
optimize_image
Fetch an image from a public URL and re-encode it smaller (WebP/AVIF/JPEG), optionally resizing to a target width. Returns the optimized image plus before/after byte sizes. Use this when an AI-generated or dropped-in asset (hero image, screenshot, illustration) is too large to ship.
storage_capacity
How many photos or minutes of video actually fit in a given storage size, corrected for real OS/filesystem overhead. Backed by Cleanor Labs measured per-item sizes. Use for realistic sample copy, dashboards, or "how many photos fit in 128 GB" answers.
image_format_savings
How much smaller WebP, AVIF or JPEG XL are than JPEG at matched perceptual quality, from Cleanor Labs’ controlled benchmark. Also reports the "HEIC conversion tax" (converting an iPhone HEIC to JPG/PNG makes it bigger). Use to justify a format choice when building a site or app.
qr_code
Encode text or a URL as a QR code and return a crisp, dependency-free SVG you can paste straight into a page, deck or doc.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Cleanor MCP is categorized under Multimedia Process and uses a local stdio subprocess. In contrast, Prompt To Asset belongs to Multimedia Process using local stdio subprocess. Select Cleanor MCP when you need capabilities focused on multimedia process and Prompt To Asset when you require tools for multimedia process.
Compute a cryptographic hash of text (SHA-1, SHA-256, SHA-384 or SHA-512) and return the hex digest. Use for checksums, cache keys, or verifying content. MD5 is intentionally not offered (broken, and unavailable in Web Crypto). LLMs cannot compute these reliably by hand, so always use this tool instead of guessing.
uuid
Generate one or more UUIDs. v4 is fully random; v7 is time-sortable (recommended for database keys). LLMs cannot produce cryptographically random or correctly-formatted UUIDs, so always use this tool.
base64
Encode text to Base64 or decode Base64 back to text (UTF-8 safe). Supports URL-safe alphabet. Use whenever you need to encode/decode data URIs, tokens, or config values instead of guessing the bytes.
json_format
Validate JSON and pretty-print or minify it, optionally sorting object keys. Returns a precise parse error (with position) if invalid. Use to check and clean JSON instead of eyeballing it.
jwt_decode
Decode a JSON Web Token into its header and payload so you can inspect claims (iss, exp, sub, scopes). The signature is NOT verified and no secret is required or stored. Use to read a token during debugging.
color
Convert a color (hex, rgb() or hsl()) and return hex, RGB and HSL representations at once. Use when picking or translating colors for CSS, design tokens or themes.
slugify
Turn a title or phrase into a clean, URL-safe slug (lowercase, hyphenated, accents stripped). Use when generating page paths, filenames or anchor IDs.
count
Accurately count characters (Unicode code points), UTF-16 units, words, lines and UTF-8 bytes in text. LLMs are notoriously bad at counting, so always use this tool for "how many characters/words" questions.

Prompt To Asset Tools (24)
asset_capabilities
Report which of the three execution modes this server can run RIGHT NOW given the current env: inline_svg (zero key — hosting LLM authors the SVG), external_prompt_only (zero key — paste prompt into Ideogram/Nano Banana/Midjourney/Recraft/Flux UIs, then asset_ingest_external), api (requires provider key). Read-only; no network. Call before offering the user options.
asset_enhance_prompt
Classify an asset brief, route to the right model, rewrite the prompt in that model's dialect, and report which execution modes are available (inline_svg / external_prompt_only / api). Returns an AssetSpec JSON including modes_available, optional svg_brief (for inline_svg), optional paste_targets (for external_prompt_only), and — when the brief leaves a material ambiguity — a `clarifying_questions[]` array the host LLM should surface via AskUserQuestion (or the equivalent) BEFORE calling a generator. Each entry has {id, header, question, options[], required, why}. Read-only; idempotent; no network.
asset_generate_logo
Generate a logo. Three modes: inline_svg (Claude emits SVG — zero key), external_prompt_only (returns prompt + paste targets — zero key), api (server runs the provider pipeline — requires key). Omit mode to auto-select. Returns an AssetBundle / InlineSvgPlan / ExternalPromptPlan discriminated by the mode field.
asset_generate_app_icon
Generate an app icon (iOS AppIconSet, Android adaptive, PWA maskable, visionOS 1024² master + placeholder parallax layers). Three modes (inline_svg / external_prompt_only / api). In non-api modes only the master mark is produced; call asset_ingest_external afterwards to run the platform fan-out. Set ios_18_appearances=true to also emit dark and tinted 1024² variants for iOS 18 tintable icons.
asset_generate_favicon
Generate a favicon bundle (favicon-{16,32,48}.png + icon.svg + icon-dark.svg + apple-touch + PWA 192/512/512-maskable + <link> snippet). Three modes — inline_svg is the best fit for simple glyph marks (legible at 16×16).
asset_generate_og_image
Render a 1200×630 OG image via Satori template (deterministic typography, no diffusion). Default mode=api renders server-side without any API key. external_prompt_only is only meaningful when with_background_image is set. inline_svg is not supported (web-font loading + precise text layout beyond LLM reach).
asset_generate_illustration
Generate one or more brand-locked illustrations. Two modes (external_prompt_only / api); inline_svg is not supported — path budget too small for a composed scene. Injects brand bundle (palette, style_refs, LoRA, style_id) where supported.
asset_generate_splash_screen
Generate a cross-platform splash-screen bundle from a brand mark. Two modes (external_prompt_only / api); inline_svg is not supported (splash screens are PNG bundles — generate a logo inline_svg first, then call this with existing_mark_svg). api mode composites the mark onto background_color and emits ios/LaunchScreen-2732.png, android/mipmap-*dpi/splash.png, android/themes-splash.xml, pwa/splash-1200.png, and a README describing how to wire each.
asset_generate_hero
Generate marketing-hero / landing-page banner art. Two modes (external_prompt_only / api); inline_svg is not supported. Accepts aspect_ratio (16:9 / 21:9 / 3:2 / 2:1). Injects brand bundle where supported. Returns N variants if count>1.
asset_remove_background
Matte an image to transparent background (BiRefNet / BRIA RMBG / U²-Net via remote endpoint; local white-chroma fallback). Returns RGBA PNG path.
asset_vectorize
Convert a raster image to SVG. Tries in order: Recraft /vectorize (if PROMPT_TO_BUNDLE_RECRAFT_VECTORIZE_URL is set), vtracer on PATH, potrace on PATH, then a built-in posterize run-length fallback. Passes all output through SVGO when installed.
asset_upscale_refine
Upscale / refine an image, asset-type-aware. DAT2 for flat logos/icons, Real-ESRGAN/SUPIR for photoreal, img2img for diffusion polish. Lanczos fallback.
