Clawhard Studio: small tools for jobs an AI cannot do reliably alone. Use tokendiet_count_tokens for exact token counts and context-window fit; swatch_check_contrast, swatch_fix_contrast, swatch_pick_text_color, swatch_make_scale, swatch_convert_color and swatch_check_pairs for exact WCAG color contrast, the nearest passing color and 50-950 palettes; meridian tools for the real current time, DST-correct time zone conversion and meeting slots; halves_settle_up for the fewest payments that settle a group (halves_create_group_link for a shared page); runsheet_create_schedule for a live shareable…

what callers paid
Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
mend_outline_json unknown never probed
Use before reading a big JSON response, log or export into context: returns a compact outline of the structure (keys, types, array lengths, one example per repeated shape) so you can plan a query without spending tokens on the whole document. Repairs the JSON first if needed. Follow with mend_query_json to pull only the values you need. Up to 100,000 characters.
tokendiet_count_tokens unknown never probed
Counts the exact number of tokens in a text with the o200k tokenizer (GPT-4o family and later), plus words and characters, and whether it fits in 128K, 200K and 1M token context windows. Language models cannot count their own tokens reliably.
halves_settle_up unknown never probed
Given a group of people and the expenses (who paid, how much, who shared it), returns each person's net balance and the smallest set of payments that squares everyone up. Splits equally by default, or by exact amounts. Stateless: nothing is saved. Use create_group instead to make a shared link people can keep adding to.
mend_query_json unknown never probed
Use when you need specific fields from a JSON document without reading all of it: $.users[0].name, $.items[*].id, $.a.b[-1], $.list[1:3], $..email (recursive). Returns each match with its exact path, type and value. Repairs the JSON first if needed, so broken input still works. Up to 100,000 characters.
slopscore_check_website unknown never probed
Fetches a public web page and its main stylesheets and scripts once, then scores it from 0 (hand-made feel) to 100 (certified slop) against 19 design and copy habits that make a site look AI-made (purple gradients, gradient headlines, glow blobs, glassmorphism, default fonts, untouched component kits, icon card grids, buzzwords, template headlines, vague social proof, placeholder testimonials,…
aitab_list_ai_plans unknown never probed
Lists the AI subscription plans AI Tab knows (chat assistants, coding tools, image and video, voice and music, work) with their USD list prices and the plan keys to pass to the total tool.
aitab_total_ai_subscriptions unknown never probed
Adds up a list of AI subscriptions and returns the monthly, yearly and daily total, where the user is paying twice for the same thing (overlaps), what could be cut and how much that saves, plus a link that opens the shareable receipt. Use plan keys from the plans tool, for example chatgpt.plus, claude.pro, cursor.pro. Append ":y" to a key for yearly billing.
tells_check_writing unknown never probed
Checks a piece of writing for the habits that make people think a chatbot wrote it (em dashes, words like "delve", assistant filler like "I hope this helps", "it's not X, it's Y", fake suspense, stiff transitions, markdown leftovers, emoji bullets, rule of three, same-length sentences). Returns a 0-100 bot-o-meter score, a verdict and the tells found. Style habits only.
runsheet_create_schedule unknown never probed
Creates a Runsheet: a live, shareable schedule for an event day (wedding, shoot, conference, any timed run of show). Start from a template or send your own items. Returns a view-only link for guests and vendors and a private edit link for the planner. Keep the edit link secret: anyone with it can change the schedule.
halves_create_group_link unknown never probed
Creates a Halves group and returns a link anyone can open (no sign-up) to add and fix expenses and see who owes whom. Optionally pre-loads expenses. Anyone who has the link can edit the group, so share it only with the people in it. Groups are kept for about 400 days after the last change.
doorman_check_ai_bot_access unknown never probed
Reads the public robots.txt of a website and reports which AI bots it lets in, by purpose: AI training (GPTBot, ClaudeBot, Google-Extended, Applebot-Extended, Meta-ExternalAgent, CCBot, Bytespider, Amazonbot and more), AI search and answers (OAI-SearchBot, Claude-SearchBot, PerplexityBot, DuckAssistBot), assistants opening pages for a person (ChatGPT-User, Claude-User, Perplexity-User,…
doorman_check_robots_txt unknown never probed
Same report as the check tool, for robots.txt text you already have (a draft, or a file from a site the checker cannot reach). Parses it the way crawlers do (RFC 9309 groups, longest-match Allow/Disallow, * and $ wildcards) and reports which AI training bots, AI search bots, assistants and search engines it lets in, plus the shared __usage_ai-training preference.
doorman_write_robots_txt unknown never probed
Builds a robots.txt from a simple choice: AI training in or out, AI search in or out, assistants in or out. Keeps every rule in the existing file (pass it as robots_txt), removes old lines for the AI bots it manages, and adds one clearly labelled block, including the shared User-agent: __usage_ai-training preference. Never touches Googlebot, Bingbot or Applebot, so normal search is unaffected.
swatch_check_contrast unknown never probed
Use when you pick, review or generate UI colors and need an exact accessibility answer. Computes the WCAG 2.x contrast ratio of a text color on a background (never guess ratios, LLMs get them wrong) and returns pass or fail for AA and AAA at normal and large text, the 3:1 UI-component rule, and the APCA Lc score.
swatch_fix_contrast unknown never probed
Use when a color pair fails contrast and you need a replacement that still looks like the original. Returns the nearest passing text color (background fixed) and the nearest passing background (text fixed), keeping hue and changing only lightness, with the new exact ratios. Targets: AA (4.5:1 normal text, default), AAA (7:1), AA-large (3:1 large text), ui (3:1 icons and borders).
swatch_pick_text_color unknown never probed
Use when you place text or an icon on a colored surface (button, badge, chip, tag, hero) and need the readable text color. Returns whichever of black or white has the higher contrast ratio, both ratios, the grade, and a softer near-black or near-white option that still passes AA.
swatch_make_scale unknown never probed
Use when you need a design-token palette from a brand color. Generates an 11-step scale (50, 100 ... 950) in OKLCH so steps look evenly spaced, with your exact color kept as the closest step. Returns each step's hex, contrast on white and black, the best text color on it, and ready-to-paste CSS variables, a Tailwind colors block and JSON.
swatch_convert_color unknown never probed
Use when you need the same color in another CSS format, or a color name turned into a value. Returns hex, rgb(), hsl(), oklch(), relative luminance and the nearest CSS color name. Accepts hex, rgb(), hsl(), hwb(), oklch() and CSS names.
swatch_check_pairs unknown never probed
Use to audit a whole UI or design-token set in one call. Takes up to 50 pairs and returns each pair's ratio, grade and AA/AAA results, plus how many fail AA for normal text. Ideal after you generate a theme or dark mode and want every text-on-surface pair verified.
meridian_now unknown never probed
Use whenever you need to know what time or date it is right now somewhere. You have no clock of your own, so never guess the current time. Returns the real current time, date, UTC offset, abbreviation and daylight saving status for each place. Places can be cities ("Tokyo"), IANA zones ("Europe/Paris"), abbreviations ("PST") or "UTC+5:30".
meridian_convert_time unknown never probed
Use to convert a specific wall-clock time from one place to others, for any date. It uses the real tz database, so daylight saving is right for that exact date (the US and Europe switch on different weeks), and it warns when the time does not exist (spring forward) or happens twice (fall back). Time accepts "15:00", "3:30pm", "noon", "now" or an ISO local time like 2026-11-05T15:00 (no Z).
meridian_meeting_slots unknown never probed
Use to schedule a call across several places. Scans the day in 15-minute steps and ranks start times so the most people are inside working hours and nobody is at night, using each place's real offset and DST for that date. Returns up to 5 slots with each person's local start and end, and says plainly when no time works for everyone.
meridian_zone_info unknown never probed
Use to answer "what is the UTC offset of X", "does X observe daylight saving" and "when do the clocks change". Returns the current offset and abbreviation, whether the place observes DST, every clock change in the year with exact local before and after times, and the next change. Abbreviations like IST or CST are ambiguous, so the answer says which zone was used.
mend_repair_json unknown never probed
Use when JSON from an LLM, API, log, config or copy-paste fails to parse (JSON.parse error, "Unexpected token", "Expecting property name"), or the user pastes JSON with trailing commas, single quotes, unquoted keys, comments, Python True/False/None, NaN, missing commas or brackets, a ```json fence, text around it, or output that was cut off.
mend_check_json unknown never probed
Use when you need to know whether text is strictly valid JSON, and if not, exactly where it breaks. Strict RFC 8259 check (the same accept/reject as JSON.parse). Returns line, column, the offending line with a caret and whether Mend can repair it. Use mend_repair_json to fix it. Up to 100,000 characters.
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
