billr

billr

By Hedinger Digital

billr is a Swiss invoicing app for freelancers, agencies and small businesses. The billr connector lets you run your invoicing in plain language: • Time tracking: "Log 2.5 hours on the website relaunch for yesterday" • Invoices: create invoices directly or from unbilled time, send them with a Swiss QR bill, send payment reminders, mark them as paid • Quotes: create, send and turn quotes into projects or invoices • Overview: open and overdue amounts, aging report, monthly revenue and expenses, hours per customer or project • Customers, projects, products, suppliers and expenses • Invoice and quote PDFs via a short-lived download link Each connection is bound to the one billr organization you choose when connecting, and you can disconnect at any time in billr under Einstellungen → KI-Assistenten. Actions that e-mail your customers or change existing data are marked as such, so Claude asks before running them. Requires a billr account (billr.ch); the billr app is in German. billr is developed and operated by Hedinger Digital. Support: support@hedinger-digital.ch

bimetrics

bimetrics

By bimetrics GmbH

Buchhaltung und E-Rechnungen für Selbstständige und Unternehmen. Verbinde die Buchhaltungssoftware bimetrics mit Claude, um Belege und Bankumsätze zu finden, offene Rechnungen und Forderungen zu prüfen und den Monatsabschluss vor dem DATEV-Export vorzubereiten. Mit Schreibzugriff arbeitet Claude wie in der App: Kontakte pflegen, Rechnungen, Angebote und Auftragsbestätigungen schreiben, Zahlungserinnerungen und Mahnungen erstellen, ausgestellte Rechnungen per Rechnungskorrektur mindern, Zahlungen zuordnen und Belege berichtigen. Vor dem Festschreiben oder Ausstellen zeigt Claude dir die aktuelle Vorschau und wartet auf deine Bestätigung. Kann Claude ein PDF nicht anzeigen, prüfst du es in bimetrics. Festgeschriebene Rechnungen und ZUGFeRD-E-Rechnungen sind endgültig; Belege mit festgeschriebenen Buchungen bleiben gesperrt. Lade Belege als PDF, JPEG, PNG oder E-Rechnungs-XML hoch und Rechnungen, Angebote und Mahnungen als PDF herunter. Bereits erfolgte Erstattungen hältst du fest, Serien bereiten Rechnungsentwürfe vor. bimetrics versendet nichts und löst keine Zahlungen aus; das Vollstorno bleibt in der bimetrics-App. Du brauchst einen bimetrics-Account mit passendem Tarif und MCP-Rechten für die ausgewählten Unternehmen. Rechnungen schreiben setzt einen Unternehmenssitz in Deutschland voraus.

bitHuman docs

bitHuman docs

By bitHuman Inc.

The bitHuman docs (docs.bithuman.ai) as a remote MCP server. Two read-only tools: search finds pages, and fetch returns one as markdown. It needs no account and no key. bitHuman has two current models: Essence 2 renders a photoreal person from one portrait; Expression 2 renders any character (people, animals, cartoons) from one portrait. Ways to build: the Swift package (iOS, iPadOS, macOS), the Android SDK (Maven Central), the Python SDK (bithuman), the CLI with a built-in MCP server, the LiveKit Agents plugin, the Flutter plugin, the web embed and the REST API. Ask about any of them; each answer comes from a docs page and carries its URL.

bluerails

bluerails

By Bluerails

bluerails helps users find hotels in Germany, Austria and Switzerland by place, radius, country and hotel classification. For specified dates and guests, it retrieves available room offers, whole-stay totals, average nightly prices, and cancellation terms and photos where supplied. Users can compare offers against a nightly budget and follow booking links to complete reservations on external booking sites; dates and guest details are included where supported. When rates cannot be retrieved, the app reports prices as unknown and provides a booking link where one is available. Confirmed unavailability is distinguished from failed rate lookups. Hotel and room results are displayed inline in the conversation.

briq

briq

By Uplab

briq gives your agent its own cloud. In one MCP call it runs Postgres, Redis, MySQL, MongoDB, a headless Chrome, Metabase, an app from a GitHub repo, or any public Docker image, each on its own microVM, and returns connection strings and URLs instead of Dockerfiles. The agent can run commands and read logs inside a service, write and read files, publish a service on an HTTPS URL (public or behind a token) or a Postgres TCP endpoint, fork a database or a whole stack before a risky change, and set when a service sleeps. Services stop when nobody uses them and wake on the next call or request. You sign in through the browser and pick the team and the budget the agent gets. Usage is billed by the second against that budget. Each team has its own private network. EU-hosted by default.

bryny

bryny

By bryny

bryny MCP Server connects your AI assistant to your own operational data on the bryny fulfilment and logistics platform in Tunisia. Merchants who store their physical goods in bryny warehouses can ask, in plain language, how their orders are progressing, which products are running out of stock, where a parcel is, and how their fulfilment activity is doing — without opening a dashboard. Access is strictly scoped: you only ever see the data of the account you signed in with. A merchant sees their own orders, products, stock and deliveries; a customer sees their own orders and returns; an administrator sees platform-wide operations. Key capabilities: • Order operations: list, search, filter and analyse your own orders and their delivery statuses • Inventory and stock: real-time stock levels, low-stock and out-of-stock alerts, stock movements • Shop operations: your shop profile, product records and fulfilment activity summaries • Logistics: parcel tracking, delivery progress and delivery failure analysis • Support: your own support tickets and customer returns • Platform health: service status and audit trail (administrators only) No purchase, cart, checkout or payment exists in this app. Every transaction happens outside ChatGPT: end customers pay the delivery driver in cash when the parcel arrives, and bryny never collects card or bank details.

buddydayplanner

buddydayplanner

By YUVRAJ BARSARA

Buddy Day Planner is the day planner you talk to. With this plugin, you can plan in ChatGPT and send the result to the Buddy app on your iPhone. Ask ChatGPT to plan something: a study week, a weekend of chores, the next steps of a project. ChatGPT shows the tasks on a card first, with the day, the time, how long each one takes, and any reminder or repeat. Leave out the ones you don't want, then tap Send. The tasks wait in Drafts in Buddy. Nothing goes on your plan until you add it there yourself. ChatGPT can only send tasks to Buddy. It can't see, change or delete anything already in Buddy. To connect, you need the Buddy app on iPhone, signed in, with your age set to 18 or over. In Buddy, open Account, then Tasks. Under Connected apps, tap ChatGPT, then Get a code. Type the code on the page ChatGPT opens, then tap Allow in Buddy.

camelBots

camelBots

By camelAI

camelBots turns a description into a running Discord bot. Say what your bot should do, for example roll dice for game night, welcome new members or run a trivia round, and camel-builder, camelBots' builder, writes its code, tries it in a private test channel and saves it. Ask for changes in plain words; when you are happy, publish it and add it to your server with one link that opens Discord's own screen. camelBots hosts the bot for you: there is nothing to install or keep running. It is for community owners, moderators and anyone who wants a custom bot without writing or hosting code. The app acts only on the camelBots account you sign in with, and only on its bots. A bot stays a draft until you publish it, and adding it to a server always happens on Discord's screen, where you pick a server you manage. It never asks for Discord bot tokens or other credentials in the conversation: camelBots asks for them on its own pages. Deleting a bot is done in camelBots itself.

camelRun

camelRun

By camelAI

camelRun is camelAI's hosted runtime for AI agents. Connect your camelRun account to create agents from a plain-language description, give them built-in tools such as web search, run them and read their replies, and deploy agent.yaml manifests that keep an agent's configuration as a reusable, versioned definition. Agents are durable: each keeps its history until you delete it, can wake itself on a schedule, and can stop to ask you a question or for an approval, which you answer from the conversation. It is for developers and teams who build agents for their products or their own work and want to try, adjust and manage them without leaving the conversation. The plugin acts only on the camelRun account you sign in with, and only on its agents, definitions and schedules. Runs use your account's credit. It does not manage billing, API tokens or provider keys; do those in the camelRun console. Tool servers that need secrets are best deployed with the camelrun CLI, which reads them from its environment, so credentials never pass through the conversation. Deleting an agent or definition cannot be undone, so you are asked to confirm first.

cf0 Zero

cf0 Zero

By cf0, Corp.

cf0 Zero connects your firm's Zero, the AI assistant in cf0, to Claude. It is for staff at property management, lettings and short-term rental firms that work in cf0. Ask Zero what it is handling, what is waiting on you, and where a task stands. Asking changes nothing and contacts no one. Hand Zero one task about one person already on your firm's records, such as arranging access with a tenant for a repair visit, confirming a check-out time with a guest, or telling an owner about booked work. Zero drafts one email from your firm's own Zero mailbox and sends it only after someone at your firm approves it. Answer what Zero is waiting on: approve or decline an ordinary email after a preview of the person's role, the property, the send time in your firm's time zone and the full message; answer a question Zero asked about your task; or cancel a task. People on your firm's records appear as reference codes with their role, and contact details and access codes are hidden. A name that is not on your firm's records, such as one typed into the chat, is passed back as written. Zero never uses a phone number or email address typed into the chat, and never takes leasing, leads, cold outreach, marketing, tenant screening, rent or arrears, payments, legal notices or emergencies. Messages to 10 or more people, documents and sensitive content are approved only on cf0.ai.

chask

chask

By chask

Chask connects your AI assistant to your organization's map : a living picture of who does what, with which tools, and how work flows between people. With it, your assistant can: • Read the map — floors (teams or areas), people, platforms such as Gmail, Slack, HubSpot or your ERP, and the connections between them. Search by name and review the change history. • Build and edit the map — create floors, add people and platforms, connect them, move nodes and auto-arrange a floor. • Document processes — create step-by-step workflows (who does each step and with which tool), review suggested processes and archive the ones you no longer use. • Guide setup — see what the map is missing and walk through the initial setup. • Design automations — ask the canvas agent to draw how a connection works and turn it into an automation pipeline. • Bring your team in — list teams and invite the people on your map (always confirmed with you first, since it sends an email). Everything runs with your own Chask permissions: the assistant only sees the organizations you belong to and respects each floor's access. Destructive actions (deleting nodes or connections, archiving floors or processes) are marked so your client asks for confirmation, and every change appears in the map's action history. Requires a Chask account (free plan available at chask.io).

check.tattoo: tattoo size and placement guide

check.tattoo: tattoo size and placement guide

By check.tattoo

Reference tools for anyone planning a tattoo. Describe the kind of design (lettering, a bold symbol, a botanical, a realistic face and so on), its size and, if known, where it will go and in what style. The connector compares the size with the published minimum for that kind of design, returns the placement's fade, sun, friction, stretch and curvature estimates and its pain band, adds style notes, and lists things to look at and questions to take to the artist. It can also return the full size chart (smallest and better sizes for eight kinds of design, with real-world size comparisons), compare the ten common body areas side by side, check whether the gap between two lines will stay open as a tattoo ages, and give a pre-booking checklist: what to settle and ask before paying a deposit. The numbers come from the guides published at check.tattoo. They are coarse estimates for comparison, not measurements, and the answers are general guidance rather than a prediction for a specific design or a specific person's skin. The connector does not generate designs, read images or photos, book appointments or give medical advice. An experienced tattoo artist has the final word. All five tools are read-only, need no account and keep nothing they receive.
