• search_docs

  Uploadkit

  Full-text search across every UploadKit docs page (88+ pages — getting-started, core-concepts, SDK reference, API reference, dashboard, guides). Ranks matches by keyword frequency in title, description, and body. When to use: any question about UploadKit behaviour, configuration, or integration that the component tools do not answer — middleware, onUploadComplete callbacks, REST API endpoints, webhooks, presigned URLs, CSS theming variables, type-safety setup, migration from UploadThing, rate limits, etc. Returns: JSON { query, count, indexGeneratedAt, matches: [{ path, url, title, description, snippet, score }] }. Sorted by score descending. Read-only. Bundled index (no network call) — results reflect docs at build time.

• update_doc

  Dock

  Replace a workspace's doc body. Takes EITHER TipTap JSON (`content`) OR Markdown (`markdown`): pass markdown when you're producing prose from scratch (CommonMark + GFM is the format every LLM emits natively), pass TipTap JSON when you need structural edits to an existing doc (round-trip from get_doc, mutate, write back). Beyond CommonMark + GFM, the markdown layer recognizes: - **** → inline image. Use ANY publicly-reachable URL (HTTPS preferred — HTTP fires browser mixed-content warnings; data: URIs are rejected by `allowBase64: false`). Renders block-feeling via CSS (max-width 100%, rounded corners, drop shadow) even though the underlying node is inline. The `alt` text is the accessible label and shows in place of the image if the URL fails to load — always include it. To attach a user-uploaded file, hit `POST /api/workspaces/:slug/upload-image` from the human-side UI first to get a Vercel Blob URL, then reference that URL in the doc markdown. - A **lone video-file URL on its own line** (extension `.mp4` / `.m4v` / `.webm` / `.mov` / `.mkv`, signed-params + timestamp fragments tolerated) → native HTML5 `<video controls preload="metadata">` player. Source URL is referenced directly: no iframe, no transcoding, no quality loss. Vercel Blob is the canonical hosting (5 GB per file, served with HTTP range requests so 4K masters stream cleanly), but ANY publicly-reachable HTTPS URL works. Sample shape: a paragraph containing only `https://cdn.dock.ai/2025-launch-walkthrough.mp4`. Mid-paragraph URLs stay as plain links — surrounding prose disqualifies the auto-promotion (matches the oEmbed convention). - **```mermaid** fenced code → diagram (15 sub-types: flowchart, sequence, gantt, ER, state, class, mindmap, timeline, pie, quadrant, sankey, XY-chart, packet, block, journey) - **$x$** inline math, **$$x$$** block math (LaTeX, KaTeX-rendered, scripts/href disabled) - **> [!NOTE]** / **[!TIP]** / **[!IMPORTANT]** / **[!WARNING]** / **[!CAUTION]** GFM-style callouts - **```svg** fenced code → sanitized SVG embed (the universal escape hatch for custom diagrams; scripts and event handlers stripped at write time) - **<details><summary>X</summary>BODY</details>** → collapsible toggle - **[[slug]]** / **[[org/slug]]** / **[[slug#tab]]** / **[[slug#row-id]]** / **[[slug|display]]** → cross-references to another workspace, surface, or row. Resolved against your accessible workspace set; targets you can't see render as plain text on the reader's side (no info leak). Every cross-ref creates a Backlink row so the target's 'referenced from' sidebar shows this doc. - **[@Label](dock:mention/<kind>/<id>)** → @-mention of a user or agent. `<kind>` is `agent` or `human`; `<id>` is the principal id. Optional query params `?org=<slug>` (agents) or `?email=<addr>` (humans) for renderer hints. Mentioning a human writes a `doc_mention` row to their inbox + sends a deep-link email; mentioning an agent fires the `doc.mention_added` webhook so the agent service can wake up and reply. Re-saving a doc that already mentions someone does NOT re-fire — only newly-added mentions notify (computed from a diff against the previous body). Use this from agent code to ping a teammate when a doc you wrote needs their eyes. - A **lone URL on its own line** from a safelisted provider (YouTube, Vimeo, Loom, Figma, CodePen, GitHub gists) → sandboxed iframe embed. Other URLs stay as regular links. Surrounding prose disqualifies the auto-embed. Per-format caps: max 50 Mermaid diagrams (30 KB source each), max 500 math expressions (8 KB source each), max 50 SVG blocks (100 KB source each post-sanitize), max 200 cross-refs per doc, max 500 @-mentions per doc, max 20 embeds per doc, max 20 videos per doc (5 GB per file at upload time), max 200 images per doc. See /docs/doc-formats for examples. Last-write-wins; no CRDT merge. Emits doc.updated + doc.heading_added + doc.mention_added events as applicable. Requires editor role. Multi-surface workspaces optionally accept `surface_slug` to write to a specific doc tab; omitted writes the primary doc surface. Append-only updates have a dedicated `append_doc_section` tool that doesn't require fetching the body first.

• documents_create

  DialogBrain

  Render a document (PDF / HTML / PPTX / DOCX) and save it to the workspace. This tool has two input pipelines — pass **exactly one** of `content_html` or `content_markdown`. # Pipeline A — `content_html` (canonical for decks, proposals, designed pages) You author full HTML+CSS. A baked-in design-system preamble ships first (`<style>` with Inter/Manrope as data-URI fonts, CSS-variable palette tokens, 8px spacing scale, and pre-styled layout helpers); your markup and any of your own `<style>` blocks land after the preamble so you can override anything. Chromium renders the assembled document into a static PDF — JavaScript is disabled and DNS is blackholed, so external font / image / script fetches will fail by configuration. Required when this pipeline is used: - `title` — human-readable, used for PDF metadata and the saved filename. - `content_html` — the `<body>` and any custom `<style>` blocks. The renderer wraps this in `<html>…</html>` and injects the preamble + a canonical `<meta charset>` + `<title>`. Do NOT emit `<script>`, `<iframe>`, `<object>`, `<embed>`, `<meta>`, `<link>`, `<base>`, `<form>`, or event handlers — the sanitizer strips them. - `output_type` — `"pdf"` or `"html"`. (`"pptx"` and `"docx"` require `content_markdown` since they need structured markdown intermediates.) Optional: - `page_preset` — `"slide_16_9"` (default for any deck), `"a4"` (default for flowing documents — used if omitted), `"letter"`, or `"none"` (you declare your own `@page` rule). For a web-styled page (dark background, full-bleed sections) use `"none"` and declare `@page { margin: 0 }`, set the background on `html` as well as `body`, and add `print-color-adjust: exact` — the a4/letter presets keep 24mm paper margins, which paint as a white frame around dark designs. - `design_tokens` — flat dict overriding the preamble's CSS variables. Whitelisted keys: `brand_primary`, `accent`, `surface_dark` (hex color), `font_display`, `font_body` (font name from ['Inter', 'Manrope', 'monospace', 'sans-serif', 'serif', 'system-ui', 'ui-monospace', 'ui-sans-serif', 'ui-serif']). - `language` — BCP-47 tag (default `"en"`). Drives `<html lang>`. ## Slide structure (`page_preset="slide_16_9"`) Each slide is `<section class="slide …">…</section>`. The base `.slide` class is what sizes it to the viewport and forces the page break — do not drop it. Composable variants (apply alongside `.slide`): - `.slide-cover` — gradient hero, big display title. - `.slide-split` — two equal columns, image + narrative. - `.slide-stats` — three-up KPI cards (use `<div class="stat">` with `.stat-value` + `.stat-label` inside). - `.slide-quote` — centered pull quote + `<cite>` attribution. Layout helpers (work in any preset): `.grid-2`, `.grid-3`, `.split`, `.stack`, `.cluster`, `.callout`, `.muted`, `.kbd`. ## Speaker notes `<aside class="notes">…text…</aside>` inside a `<section class="slide">`. The sanitizer strips them from the rendered PDF and returns them as `slide_notes[]` (parallel to slide order). Orphan notes outside any slide are dropped with a warning. ## Images Only these `src` schemes resolve: - `file:NNN` — workspace `file_id`. - `data:image/...;base64,...` — inline. - `https://<host>` where `<host>` ∈ `DOCUMENTS_MEDIA_URL_ALLOWLIST`. Other URLs are dropped and replaced with an HTML comment placeholder. # Pipeline B — `content_markdown` (invoice / contract only) Required: - `title`, `content_markdown`, `output_type`. Optional: - `theme` — `"invoice"` or `"contract"`. Triggers the corresponding exemplar styling and (for invoices) the arithmetic validator that fail-closes on missing or mismatched totals. - `language` — BCP-47 (default `"en"`). # Delivery contract (CRITICAL) After this tool returns `file_id`, deliver the file with `messages.send(attachments=[file_id], text="<short caption>")`. Embedding the file_id in a markdown link, `sandbox:` URL, or `/api/files/<id>/download` text will render as plain text on the recipient's channel — the `attachments` parameter is the only way the file actually attaches. # Exemplars INVOICE (English): # Invoice INV-{YYYYMMDD-HHMMSS} **From:** {Issuer Legal Name}, {Address}, {Tax ID} **To:** {Customer Name}, {Customer Address}, {Customer Tax ID} **Issue date:** {YYYY-MM-DD} **Due date:** {YYYY-MM-DD} | Description | Qty | Unit price | Total | |---|---:|---:|---:| | {Service 1} | 1 | 1500.00 | 1500.00 | | {Service 2} | 2 | 500.00 | 1000.00 | **Subtotal:** USD 2500.00 **Tax (20%):** USD 500.00 **Total:** USD 3000.00 **Payment:** {bank details OR crypto wallet — never both} INVOICE (Russian): # Счёт-фактура № INV-{YYYYMMDD-HHMMSS} **От:** {Юридическое название организации}, {Адрес}, ИНН {Tax ID} **Кому:** {Название клиента}, {Адрес клиента}, ИНН {Tax ID} **Дата:** {YYYY-MM-DD} **Срок оплаты:** {YYYY-MM-DD} | Описание | Кол-во | Цена | Сумма | |---|---:|---:|---:| | {Услуга 1} | 1 | 1500.00 | 1500.00 | | {Услуга 2} | 2 | 500.00 | 1000.00 | **Подытог:** USD 2500.00 **НДС (20%):** USD 500.00 **Итого:** USD 3000.00 **Реквизиты:** {банковские реквизиты ИЛИ криптокошелёк — не оба сразу} CONTRACT (English): # Service Agreement **Between:** {Provider Legal Name}, {Address} ("Provider") **And:** {Client Legal Name}, {Address} ("Client") **Effective date:** {YYYY-MM-DD} ## 1.

• convert_color

  rnv-color-mcp

  Convert a color between formats. Input accepts a hex, CSS name, RNV brand name, or saved-palette reference. With `to` set to one of hex/rgb/hsv/hsl/lab, returns just that format; otherwise returns all of them. Read-only and deterministic, with no side effects. Use for format conversion of a single color; to blend several colors into one use mix_colors, and to compare two colors use color_difference.

• generate_harmony

  rnv-color-mcp

  Generate a color harmony from a base color. base accepts a hex, CSS name, RNV brand name, or saved-palette reference (e.g. 'Spring line:2'). scheme is one of: complementary, analogous, triadic, split-complementary, tetradic (a.k.a. square), monochromatic, compound. Returns a list of hex colors. Read-only and deterministic: it derives the colors from the base and stores nothing, so it has no side effects and is safe to call repeatedly. Use to expand one base color into a related set; to blend existing colors into a single color use mix_colors, and to persist a set you like use save_palette.

• mix_colors

  rnv-color-mcp

  Blend up to 12 colors into one. Each color may be a hex (#d2bc93), a CSS name (red), an RNV brand name (brand gold, near-black), or a saved-palette reference (Spring line, or 'Spring line:2' for its 2nd swatch). Optional integer weights bias the blend (defaults to equal). mode selects the model: rgb/hsv/lab are digital blends (lab is perceptual and the default, best for on-screen color); paint mixes pigments via Kubelka-Munk physics (colors darken like real paint, use it for physical-media matching); ryb is the artist's color wheel; cmy is subtractive like printer inks. Returns hex and rgb. Read-only and deterministic: it computes a result and stores nothing, so it is safe to call repeatedly with no side effects. Use to combine multiple colors into a single blend; to convert one color between formats use convert_color, and to measure how far apart two colors are use color_difference.

  Connector

• color_difference

  rnv-color-mcp

  Perceptual difference (Delta-E) between two colors. color1 and color2 accept a hex, CSS name, RNV brand name, or saved-palette reference. method is 'ciede2000' (default, modern standard) or 'cie76'. A value near 1.0 is the threshold the eye can just notice; larger means more different. Returns the value and a plain-language interpretation. Read-only and deterministic, with no side effects. Use ciede2000 for accuracy and pick cie76 only to match a legacy system; to test whether text is legible on a background (not raw difference) use contrast_check instead.

  Connector

• contrast_check

  rnv-color-mcp

  WCAG contrast ratio between a foreground and background color, for accessibility. Both accept a hex, CSS name, RNV brand name, or saved-palette reference. Returns the ratio (1.0-21.0) plus pass/fail for AA and AAA at normal and large text sizes and for UI components. Read-only and deterministic, with no side effects. Use this for legibility and accessibility checks; to measure raw perceptual difference between two colors rather than readability use color_difference instead.

• publish_website

  Yeetit - POST HTML, get a URL. No account needed.

  Publish HTML content to a live URL instantly. No account or API key required. Returns a public URL that anyone can visit. Sites expire after 24 hours unless the owner claims them. Use this when a user asks you to build, create, or deploy a website, landing page, invitation, portfolio, report, or any HTML content they want to share as a link. Supports bundled assets (CSS, JS, images) and multi-page sites (include additional .html files in assets, accessible at /{slug}/{pagename}). IMPORTANT: After publishing, always share the live URL and the claim URL with the user. The claim URL lets them take permanent ownership of the site. Store the edit_key from the response silently — do not show it to the user — you will need it if they ask you to make changes to the site later. If you lose the edit_key, ask the user to claim the site first (via the claim URL in the page footer), then provide you with their API key from the dashboard — you can use that instead.

• tela_inspect

  DERO MCP Server

  Composite: fetch a TELA contract by SCID (DERO.GetSC code + variables) and parse it as either a TELA-INDEX-1 app manifest or a TELA-DOC-1 file contract, auto-detecting which standard it is from the stored keys. TELA is DERO's on-chain web-app platform: an INDEX is the app manifest (like package.json) and DOCs are the individual files (HTML/CSS/JS) stored on chain. When to call: as the FIRST step whenever a user references a TELA SCID, a `.tela` dURL app, or asks "what is this TELA contract/app", "what files does this TELA app have", or "is this a TELA INDEX or DOC". PREFER this over dero_get_sc + manual parsing or explain_smart_contract: explain_smart_contract treats TELA contracts as generic DVM and its surface CAPS stored keys at 50, which silently drops DOCn entries on large manifests — tela_inspect reads the raw stringkeys directly so it enumerates ALL DOC references, and it decodes the TELA header/mods/commit schema the generic tool does not understand. Input Requirements: - `scid` is REQUIRED. Must be 64 hex chars (the TELA contract id). - `topoheight` is OPTIONAL. Provide to inspect at a specific topo height; omit for the latest committed state. Output: a discriminated union on `kind`. `tela_index` → `{ scid, topoheight, kind, index: { name, description, icon, durl, mods[], docs:[{position, key, scid, is_entrypoint, malformed}], doc_count, commit, version_history[], current_commit_hash, owner, updateable:'unknown', updateable_note, parse_notes[] }, narrative, related_docs }`. `tela_doc` → `{ ..., doc: { filename, doc_type, sub_dir, durl, signature, content_embedded, code_size_bytes, immutable }, narrative, related_docs }`. `not_tela` → `{ ..., kind:'not_tela', reason, observed:{ stringkey_sample[], stringkeys_total, has_code, markers[] }, narrative }` — returned (NOT an error) when the SCID is unknown or lacks TELA markers. Updateability cannot be derived from chain state (ringsize is not in GetSC) so it is honestly reported as 'unknown'.
