Atlas
By Hostfi Inc. dba Atlas
Atlas is your AI contract agent. Unlimited e-sign is free, with no credit card required. Draft an agreement in the conversation, or share a PDF or DOCX, and Atlas turns it into a signable document: it detects signature lines, dates, and fields, and works out who signs what. You get a review link, click Send, and signers get a clean signing page on any device with no account needed. Ask things like "send this MSA to sarah@acme.com for signature," "who still hasn't signed?", "remind them," or "pull the payment terms from the signed contract." Repeat sends run from saved templates in one message. Atlas is review-first: it prepares everything and a human approves before any signature request goes out. Every signed document includes a completion certificate and a full audit trail.

Atlas AI Agent
By Ayonix
Atlas AI Agent brings your Atlas workspace into ChatGPT, with three assistants in one place. Ask for a briefing and the executive assistant reads your connected mailbox and calendar to tell you what needs attention today, what decisions are pending, and what you're still waiting on. Ask about sales and you get live pipeline figures, your leads ranked by score across campaigns, and a personalised outreach email drafted for whichever lead you name. Ask about marketing and you get channel performance, everything in the content queue with its status, whatever is sitting in your approvals, and new post drafts on request. Nothing is sent or published from ChatGPT. Outreach emails and social posts come back as drafts you approve inside Atlas, so the assistant can never speak to a customer on your behalf without you seeing it first. Connecting is a normal sign-in, and permissions are granted per assistant: you can give ChatGPT your marketing without handing over your inbox, and disconnect any time from Atlas under Connected apps.

Atlas Red
By SINISA DUKIC
Atlas Red is a workspace for structured mind maps. A map is a tree of topics, and every topic in a map shares the same author-defined fields — plain text, or typed ones like a select with its own options, a number or a date — so a map behaves like a small database you can see. Connect your account and you can create maps, read a single topic's neighbourhood without pulling in the whole map, add and reorganise topics, fill in typed fields, link topics across branches, and import or export maps as Markdown, OPML, YAML and other formats. Every change is saved to your account, and anything you do here can be undone — from this conversation or later in the app. The maps persist and stay yours: the same map opens in the Atlas Red web app on any device, on a visual canvas where you can rearrange it, colour it by one of its fields, attach images and share a read-only link.

Atlas · Name Abogados
By Name Abogados
Atlas hace parte del ecosistema de conocimiento de Name Abogados, firma colombiana de derecho público y contratación estatal. Es una infraestructura tecnológica de conocimiento abierta: sin registro, sin pago y sin barreras de consulta. Atlas no es solo un repositorio de documentos oficiales de derecho público colombiano: de cada fuente elaboramos una ficha documental, un trabajo propio que dice de qué trata el documento y lo clasifica por tipo, materia y autoridad. El documento es de la autoridad que lo expidió; la ficha es nuestra. Con este conector, Claude busca en Atlas por tema, por número de documento o por la norma citada, y lee las fichas para decidir qué documentos sirven a su caso. Atlas es un filtro de entrada: cada ficha trae el enlace al documento oficial, que es el que se lee. Atlas está en crecimiento. Hoy reúne fichas de los conceptos de Colombia Compra Eficiente sobre contratación estatal, y se ampliará a otras autoridades y a otras áreas del derecho público. Herramientas: atlas_buscar (búsqueda con filtros) y atlas_obtener (la ficha completa de un documento). Solo lectura.

AtlasBurn
By AtlasBurn
AtlasBurn connects Claude to your real AI usage and cost data so you can ask where your LLM spend is going and catch problems before they become a large bill. What you can ask: - Total AI spend, token usage, and request volume over any window - Cost broken down by model and by product feature, so you can see what is actually driving the bill - Projected monthly bill, current daily burn, and budget runway - Guardrail status: whether budgets are enabled, the enforcement state (active, throttled, or suspended), configured daily and hourly limits, and recent breaches - Runtime signals such as retry rate, loop probability, and context growth, to spot an agent stuck in a retry loop or running away AtlasBurn works across OpenAI, Anthropic, Google Gemini, and other providers. Telemetry comes from the AtlasBurn SDK or edge proxy that you add to your app. The connector is read-only and content-blind: it reads cost and usage telemetry from your AtlasBurn workspace, never changes your settings or budgets, and never sees your prompts or model outputs. Sign-in uses OAuth with your AtlasBurn account, and access is scoped to your own organization's data.

Atlavium
By Denis Zunke
Explore the worlds you build and the stories you play. Atlavium connects ChatGPT to the knowledge in your Atlavium, helping worldbuilders, game masters, and players work with their own notes and sources. For worldbuilders, bring together lore about people, places, and factions, trace recorded relationships and world events, and revisit your setting's history. Compare source passages as you develop an idea, or calculate dates using your world's own calendar. Your existing lore gives you a starting point for what comes next. Game masters can prepare a session from relevant locations, characters, past events, and open quests, then look up the details they need during play. Players can revisit their character journals, recall encounters, and follow the people and places that matter to their character's story. Choose a Realm and ask questions in English or German. Search its Compendium, read relevant passages, summarize documents or session recaps, and explore recorded connections in the World Graph. Answers can link back to the original Atlavium sources so you can check what is established, where accounts differ, and what remains an open question. Connect your Atlavium account and approve access to get started. The plugin reads content your account can access within the selected Realm. Ideas and drafts stay in the conversation until you choose to add them in Atlavium. You decide what becomes Canon.

Atly
By Atly
Atly scores close to 2 million places against more than 1,400 specific intents — work friendly, gluten free, great cappuccino, dog friendly, good for a first date — using what real reviewers say, and keeps the statements behind every score. Ask for what you actually want and get a ranked shortlist with a 0–10 score per intent, quotable statements from reviews, and a link to each place. Many gluten-free results carry a safety rating, such as dedicated kitchen or cross-contamination risk. Search by city, neighborhood, or coordinates with a radius. Coverage is densest in the United States, with pockets in Mexico, Israel and Thailand. Claude never invents a place: every result comes from a live Atly lookup, and when Atly has no coverage or no matching concept, it says so.

Atom
By Atom
The Atom MCP Server is the official Model Context Protocol server for Atom, a WhatsApp Business Platform built for customer communication teams. It exposes Atom's platform capabilities as tools that AI agents and LLM clients can invoke through natural language, connecting conversational AI directly to the day-to-day work of managing WhatsApp Business operations at scale. What it enables Once connected, an AI agent has access to the data and actions that matter most for WhatsApp Business: querying account state, acting on it, and surfacing insights that would otherwise require navigating multiple dashboards. The set of available tools is organized into functional groups — each scoping a distinct area of the platform — and grows incrementally as new capabilities are added. Connections can be granted access to exactly the groups a given workflow needs. Security and access control The server implements OAuth 2.1 with PKCE for interactive clients and Client Credentials for headless integrations. Access is governed by a two-level permission model: role-based tool visibility at the account level, and per-connection toggles for fine-grained control. Every tool invocation is logged asynchronously for adoption analytics and audit. Multi-tenant isolation ensures that every agent only ever sees data belonging to the authorized account — never another tenant's. Who it's for Customer communication teams using Atom to manage WhatsApp Business at scale — who want to delegate analysis and routine operations to AI agents, build automated workflows on top of their Atom data, or integrate Atom into broader agentic pipelines.
