Wever Brief

Wever Brief

By Wever Labs

Wever Brief connects agent operators and developers to two read-only tools: the public Wever Labs daily operator brief and an operator brief builder. Read the current daily brief covering service observations and queue priorities, or supply your own service health and queue observations and have a structured brief assembled from them. The builder works only from the observations you supply. It does not poll services or access private records.

Wever Evidence

By Wever Labs

Wever Evidence connects agent operators and developers to three read-only tools: an evidence inventory check, a work-order preparation assistant, and an MCP manifest reviewer. Check what evidence is on record, assemble a structured work order from your own inputs, or review an MCP declaration for completeness. All three tools work only from information you supply or that is already public. Nothing is modified, executed, or transmitted.

Whapi

Whapi

By Whapi

Whapi is the WhatsApp marketing and automation app for Shopify, built on the official WhatsApp Business API. Connect it to Claude and run your store's WhatsApp from chat. See revenue, orders and delivery stats for every flow and campaign. Recover abandoned carts and checkouts. Send order confirmations, shipping updates and review requests. Launch broadcast campaigns to your Shopify customer segments. See why messages failed and how to fix them. Check your WhatsApp templates and Meta approval status. Search your WhatsApp support inbox on the Team plan. Create cash on delivery (COD) confirmation flows. Try asking: "How much revenue did WhatsApp bring in this month?", "Why are my messages failing?", "Send a campaign to my repeat customers." or "Set up a COD confirmation flow for new orders." Claude confirms before creating, changing or deleting anything, and every action runs the same checks as the Whapi app. New flows and campaigns go through Meta template review before they send. You sign in from the Whapi app in your Shopify admin, so each connection reaches only the store you approve. Tools depend on your plan.

Whim

Whim

By Matchy Labs Ltd

Whim turns an idea, a story or lyrics into a real sung song, with music and its own cover art. Tell ChatGPT what the song is about, or ask it to write the lyrics, and say "make it a real song". Add a sound if you have one in mind, like dreamy 80s synth-pop, late-night jazz or a big pop chorus. The song plays right in the chat. Want to send it? Tap "Get a link to share" and your song gets its own page on onwhim.app. Try a birthday song for a friend, a diss track for the dry texter, or what happened in your group chat last night. Each person can make one song here. Full songs and more are coming in the Whim iPhone app, and you can join early access from the player.

Windrose

Windrose

By Windrose World

WindRose connects Claude to real weather stations: the public WindRose network of personal weather stations (Davis, Ecowitt, Tempest, Netatmo, Ambient, AcuRite, Weather Underground and more) and the stations on your own WindRose account. Ask where it is raining right now, which station near a place recorded the strongest gust, or how this month compares with a station's own climatology. Claude can query the latest reading of every visible station, aggregate daily data across a region for studies (rain totals, frost or heat days), read any station's live conditions, daily summaries, time series, monthly normals and all-time records, and run the models WindRose uses in its app: heat-stress indices (heat index, humidex, WBGT, UTCI) and an EPA ISC3 / Cirillo-Poli dispersion screening model. Forecasts and ERA5 reanalysis from Open-Meteo are available at any point and are always labelled as model data. It also searches the official manuals of supported hardware (Davis, Ecowitt, Netatmo, WeatherFlow Tempest, AcuRite) and answers setup, calibration and troubleshooting questions with page citations. On the Business plan Claude can also manage your push alerts and one-minute monitoring windows — always with your confirmation. Values are metric with explicit units. Private stations of other users are never accessible; hardware and indoor data are shown only to the station owner. Requires a WindRose Pro (read-only) or Business (read and write) plan.

World News Sources

World News Sources

By Myungeun Lee

Find configured publisher RSS feeds and sitemaps across countries for source research, feed setup, and news monitoring projects. Search by publisher name or domain, country, endpoint type, category, language, and configuration status. View source details, browse supported countries, and inspect separate RSS and sitemap health records with actual check times, parsed item or URL counts, sample URLs, and publication-date information when available. Health is cached from bounded operator checks. Check times are separate from content dates: a reachable feed may contain old content, and a cached result may become stale. Some configured endpoints are empty, blocked, unavailable, malformed, or could not be fully checked. Country and configuration counts do not represent unique publishers or guaranteed live coverage. Sitemap indexes describe child sitemap entries; child files and article links are not validated by this plugin. Read active source-registration inventory and cached first-discovered unique article-candidate URL activity by source or country. Country counts deduplicate across sources. Every new endpoint/source binding begins with an excluded baseline; untracked periods return null, and partial initialization or collection is explicit. Calendar days use a requested IANA timezone or UTC; rolling 24 hours is separate. Activity queries read retained aggregate history in bounded ranges of up to 31 calendar days per request. Older stored dates remain queryable; periods before real recording are not reconstructed. These counts are discoveries, not publications or feed entry counts. Homepage/section/forum heuristics are separated; sitemap-index children are excluded. No semantic content deduplication is performed. World News Sources provides read-only source metadata and observation aggregates. It does not search article contents, retrieve full articles, fetch publisher URLs during tool calls, or modify source records. No account or API key is required to use its public MCP endpoint. For support, contact myungeun2dc@gmail.com.

XLSX Formula Checker

XLSX Formula Checker

By Loam

Inspect explicitly supplied XLSX workbooks or small inline workbooks with the same bounded Rust/WASM calculation engine used by Workbook Tools. Read formulas and stored values, check reported workbook issues, calculate selected outputs, and compare changes to existing literal inputs. Stored caches and fresh calculation results are reported separately. Calls do not overwrite your original file or save edited workbooks. Formula support is partial; unsupported features and resource limits are reported rather than silently treated as Excel-compatible. The service cannot control Excel, browse local files, fetch workbook URLs, or automatically access Claude attachments. Optional AI formula help sends only the task, formula and text context you explicitly supply to OpenRouter and its selected model provider; suggestions are not executed or verified. No Workbook Tools account or user API key is needed. Read the setup page for supported inputs and limits.

Xzar

Xzar

By Xzar

Xzar is the crash-test lab for AI. Connect it and Claude (or the agent you're building) works real professional cases, cut at the moment of decision, and is graded exactly against what the professional actually decided. No AI judges: the same answer always gets the same score, with a receipt. Today's live tests cover patent examination: the first decision on each claim, the decision after the applicant responds, and appeals. Each task gives the agent the case, a library of prior publications and the examination rulebook. The agent searches, reads, decides, and submits one answer. Your scorecard then compares results with simple rules of thumb, so you can see whether the AI beats a one-liner and where it fails. Cases are decided after current models were trained, so they can't have been memorized. Answer keys never leave Xzar's servers. Use it to evaluate an AI agent before deployment, compare models on real work, or find the failure patterns that decide where a person must stay in the loop. Patents are the first field; Xzar builds tests for other fields (claims, compliance, trade, contracts) on request. You need a free Xzar account (sign up at xzar.si, $5 of free credit). Each started task uses $2.00 of credit; searching, reading and checking your scorecard are free.
