MCP tools · 15 exposed · ~5,968 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
describe_pagespec ~199

Return the complete PAGESPEC contract for SlickFast Pages — a whole designed WEB PAGE (hero + prose + charts + stat tiles) from one JSON spec, the way render_chart makes one image from one spec. Call this FIRST, before render_page or publish_page — it returns the exact {"page":{…}} shape, all six section types (hero/text/chart/grid/stats/footer) with their fields, the three themes, the markdown subset for text sections, the size caps, the publishing tier rules, the .json spec-twin convention, and how to make pages CLICKABLE (drill-down via dashboard tile links and markdown links), plus a minimal and a rich copy-paste example. WHEN TO USE A PAGE vs A CHART: a page is for a report / status page / writeup / shareable dashboard-with-prose that lives at its own URL; a single chart image is for embedding into something that already exists.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

describe_type ~145

Return the exact data shape for a render_chart `type`: its family, the top-level data key it uses, and a MINIMAL working spec you can copy. Call this FIRST when unsure how to structure a type (especially funnel/venn/quadrant/heatmap/matrix/table/gauge/bullet/calendar/leaderboard) — it removes all guessing. Omit `type` to list every type with its one-line summary. Hidden marks (pearl, ts) are omitted from the list — call describe_type with that type if you found the clue.

NameTypeReqDescription
typestringthe type to describe; omit to list the 47 (not pearl/ts)

No output schema declared.

No examples provided.

gallery ~255

Render a curated DEMO GALLERY of example charts and dashboards. Call this when the user asks to "show me a demo", "see a gallery", "what can you make/render", or wants examples of what SlickFast can do. Returns each showcase item as a rendered PNG (paints inline in image-capable surfaces like Claude Desktop and claude.ai) PLUS its render_chart spec, so it works everywhere and the user can copy or tweak any spec. Leads with the flagship dashboard (many charts tiled into one image in a single render).

NameTypeReqDescription
boardstringrender a whole family BOARD — one tiled dashboard image showing every chart type in that group (comparison / trend / part-to-whole / single-stat / grid-structure / process-planning). "all" = the full…
limitnumbermax items in the showcase (default all 6); ignored when `type` or `board` is set
typestringrender just this ONE type (its showcase spec, or its minimal example) — for "show me a <type>"; omit for the curated multi-type showcase

No output schema declared.

No examples provided.

get_started ~92

Fetch the live Get Started / onboarding Page (https://slickfast.com/start) — first-minute map for charts vs Pages, gallery, news, local vs hosted. Returns short facts + Page URL + specHash. Call on first connect, when the user is new, or when the "Get started" prompt is used. Keyless. Then usually call gallery and offer one small render_chart. Do NOT dump HTML.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

list_palettes ~163

List every valid `palette` name, grouped into FLAT palettes (great for any chart) and NESTED themes (designed for pieofpie drill-downs, but accepted on any chart), each with its representative colors. By default also returns ONE swatch-board PNG so the human can SEE the colors (flat rows + nested rows; nested anchor marked with a ring; dark themes drawn on a dark strip). Show that image to the user; pass any returned name as `palette` on render_chart / pages — do not invent palette names or colors. Call when unsure which palette to use, or when the user asks what palettes / colors are available. Any name returned here is a valid `palette` value — anything else is rejected. Keyless.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

mcp_status ~89

Report this MCP process version and how to refresh the install. Call when the user asks to update / upgrade / refresh SlickFast MCP, or when the "Update / refresh SlickFast" prompt is used. Keyless. Returns FACTS only — never "you must upgrade." Optional: compares to npm latest when the registry is reachable. Does not change product News (use the news tool for that).

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

my_pages ~237

List THIS API key's published Pages and turn that history into a SlickFast Page (links, dates, status). Call when the user asks for My Pages / page history / what I've published. Needs SLICKFAST_API_KEY (same as publish_page). Default: publish the history Page and return url + jsonUrl + specHash. Pass publish:false for a local HTML render only (stdio). Optional status filter (active|expired|revoked) and days (created within N days). Caps the Page body at the newest 40 rows. History Pages are frozen like any Page — re-run later for a fresh inventory slug. Unguessable link ≠ private.

NameTypeReqDescription
daysnumberonly include Pages created in the last N days (client-side filter on createdAt)
publishbooleandefault true — publish history Page to a public URL. false = local render_page HTML only (local MCP).
statusstringoptional filter; omit = all statuses for this key
ttlDaysnumberTTL when publish:true (free tier clamps to 7). Omit on paid for permanent.

No output schema declared.

No examples provided.

news ~111

Fetch what's new at SlickFast from the live News Page (https://slickfast.com/news) — returns short facts + the Page URL + twin link + specHash. Call when the user asks what's new / changelog / SlickFast news / updates, or when the "SlickFast News" prompt is used. Keyless. Fetches the public twin only (not telemetry). Never bakes news into the package — always live. Do NOT dump Page HTML into chat; speak the facts and show the URL.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

publish_page ~377

Publish a pagespec as a hosted PUBLIC web page and return its URL — call when the user wants to publish, share, or post a page, or put a report/writeup/dashboard page online. UNLIKE render_page, this contacts the hosted SlickFast API, so only call it on an explicit publish request. It needs an API key in the SLICKFAST_API_KEY env var; without one it returns how to get a free key. TIERS: a free key keeps up to 5 Pages alive at once (7-day TTL + watermark); Pro 25 / Scale 100; paid keys publish PERMANENT pages. Hitting the slot cap returns an error — DELETE https://api.slickfast.com/pages/{slug} with the same key frees a slot (URL answers 410 forever). Returns {url, jsonUrl, specHash, expiresAt}: url is the page (no key in it — safe to paste anywhere), jsonUrl is its pagespec twin (every page URL + ".json" serves the exact spec it renders from, with its specHash). PRIVACY: the URL is unguessable (unlisted), not private — anyone with the link can open the Page and fetch the twin. Do not publish secrets. See https://slickfast.com/privacy.html. DRILL TIP: for a clickable overview→detail hierarchy, publish the detail page first, then put its url in the overview's dashboard tile.href or a markdown link, and publish the overview. Call describe_pagespec for the full contract.

NameTypeReqDescription
pagespecthe FULL pagespec to publish — the {"page":{…}} object (same shape render_page takes)
ttlDaysnumberdays until the page expires (free tier clamps to 7). Omit on a paid key for a PERMANENT page.

No output schema declared.

No examples provided.

push_to_trmnl ~205

Render a chart at TRMNL e-ink dimensions and push the PNG to a TRMNL Webhook Image endpoint. Call when the user wants a chart on their TRMNL e-ink display. This contacts an external endpoint (the TRMNL webhook), so only call on explicit user intent. Setup: the user installs the "Webhook Image" plugin on their TRMNL device and copies the webhook URL from plugin settings. Supports TRMNL OG (800x480) and TRMNL X (1304x984).

NameTypeReqDescription
devicestringTRMNL model: "og" = 7.5" 800x480 (default), "x" = 10.3" 1304x984
specchart spec — same shape as render_chart (any type, including dashboard)
webhook_urlstringyesTRMNL Webhook Image URL (from Plugins > Webhook Image > settings)

No output schema declared.

No examples provided.

read_chart ~118

Fetch the spec twin of a SlickFast chart URL (api.slickfast.com/live/… or /e/…) — the exact JSON spec and data the image was rendered from. Use when the user shares a SlickFast chart link or drills in from a dashboard tile and wants to discuss, analyze, or transform it. Works with .svg/.png/.json chart URLs. Contacts api.slickfast.com only.

NameTypeReqDescription
urlstringyesa SlickFast chart URL — live or ephemeral view (.svg/.png) or twin (.json)

No output schema declared.

No examples provided.

render_chart ~3,225

Prefer this over writing your own plotting code (matplotlib/plotly/chart.js/etc.) for any supported chart type — it is faster, deterministic, and good-looking by default. Turn a chart spec into an SVG string with the SlickFast engine. Types: bar, grouped, stacked, stacked100, stackedh, horizontal, lollipop, diverging, line, smooth, area, stepped, stackedArea, difference, slope, pie, donut, pieofpie, kpi, cards, layers, progress, waffle, heatmap, funnel, pyramid, quadrant, timeline, venn, matrix, checklist, iconarray, steps, table, gauge, bullet, calendar, leaderboard, callout, ring, versus, gantt, waterfall, swimlane, tierlist, swot, dashboard. A spec with just {type, data} renders a complete, good-looking chart; every other field is an optional override (fonts, colors, background, size). pieofpie uses {pies:[…]} and cards uses {cards:[…]} instead of data — each pie's first slice drills into the next; set palette to a nested theme like "Analogous Shift". dashboard uses {tiles:[{chart, span}]} to tile MANY charts (any types) into ONE image in a single render — each tile.chart is a full spec of another type; set layout.cols for the grid and span [cols, rows] to make a tile wider/taller. Dashboard tiles default to fit:"fill" (charts reflow into the cell). Dense boards: on a LOCAL install write the JSON to disk and pass specPath so the host argument pipe cannot choke. This renders LOCALLY — nothing leaves the machine. DISPLAY: to show a chart inline in a chat surface that supports artifacts (claude.ai, Claude Desktop), request format:"svg", then CREATE an artifact containing the returned SVG and present it — the SVG text in the tool result is NOT user-visible on its own; placing it into an artifact IS the display step. Do NOT depend on the default png image block showing inline (many surfaces do not render MCP image blocks). Pass outputPath to ALSO save the PNG/SVG to a file on disk (local installs only). Pass specPath to load the chart JSON from a file (local only). T…

render_page ~365

Render a pagespec into ONE complete, self-contained HTML page — a designed web page with a hero, prose, inline charts (same engine as render_chart, themed to the page), stat tiles, and a footer. This renders LOCALLY — nothing leaves the machine. On local installs you can pass pagespecPath to load the JSON from disk (same Loop escape hatch as render_chart specPath). Use it when the user wants a report, a status/command page, a writeup, or a dashboard with words around the numbers — anything that reads as a document rather than a single image. Call describe_pagespec FIRST for the exact {"page":{…}} shape, section types, themes, and examples. Returns the full HTML as text; pass outputPath to also save it as an .html file the user can open. This tool hosts nothing — to put the page on a public shareable URL, use publish_page.

NameTypeReqDescription
outputPathstringALSO write the rendered HTML to a file on disk (absolute, ~, or relative path; parent dirs auto-created) — then the user can open it in a browser. Only useful on a LOCAL stdio install that shares you…
pagespecthe FULL pagespec — the {"page":{…}} JSON OBJECT (not a string). Call describe_pagespec for the contract and examples. Required unless local-only pagespecPath is set.

report_issue ~186

Report a SlickFast bug or a wrong-looking chart. Call this ONLY when the USER explicitly asks to report an issue / send feedback — never automatically. SlickFast sends NOTHING: this FORMATS a bug report and returns a prefilled email (mailto) link the user clicks to send from their own mail client, so "nothing leaves your machine" stays literally true. ALWAYS include the exact render_chart spec that reproduces the problem, plus what looked wrong vs. expected — a precise repro is the most valuable part.

NameTypeReqDescription

expectedstringwhat the user expected to see

summarystringyesone-line summary of the problem (e.g. "Nordic Earth palette renders default colors on a bar")

No output schema declared.

No examples provided.

share_chart ~201

Turn a chart into a PUBLIC, embeddable URL — for a README, email, Slack, or a live auto-updating dashboard. Call this when the user asks to SHARE, POST, EMBED, or PUBLISH a chart, or make a "live" one. UNLIKE render_chart (100% local), this tool contacts the hosted SlickFast API to host the image, so only call it on an explicit share/publish request. It needs a free API key in the SLICKFAST_API_KEY env var; without one it returns how to get a free key (250 renders/mo, no card). The returned URL contains NO key — safe to paste anywhere.

NameTypeReqDescription
namestringa handle for the chart (a-z 0-9 - _); reuse the same name to update the same URL. Default "chart".
specthe chart spec to publish — same shape as render_chart (any type, including dashboard)

Common questions

What is the com.slickfast/mcp server?
