Write a system prompt, pick a model, wire in MCP servers. We pin the agent to a real phone number, keep conversation state, and ship every outbound message as iMessage.
By the numbers
Phone number per bot
Every agent gets its own line on Loki Messages. Users save the contact and just text.
Model providers
Anthropic, OpenAI, or open models on Workers AI — pick per bot, switch any time.
Runtime per conversation
Each thread runs in its own isolated runtime with durable state. No shared memory, no leaks.
Servers for you to run
Inference, tool calls, state, and delivery all run on our edge. You write the prompt.
The idea
Feels human
Loki Chat agents speak fluent iMessage because they ride on Loki Messages. They type before they answer, react to good news, send voice memos, and put choices to a vote.
Acts on the world
Wire in MCP servers — from our catalog or your own endpoint — and the agent can search, book, order, and pay on the user's behalf. When a tool needs the user's account, the bot sends an OAuth link right in the thread.
Never loses the thread
Each conversation runs in its own durable, isolated runtime. The bot remembers the thread without you wiring up storage — and it can schedule its own future messages, so follow-through doesn't depend on the user texting first.
The platform
A chatbot starts as a system prompt and a model choice. Write the personality and the rules; we run the inference loop.
Claude from Anthropic, GPT from OpenAI, or open models on Workers AI. Choose per bot to fit your latency and cost budget — switch without rewriting anything.
Wire in any MCP server — ours or yours — and the bot can book, search, order, and fetch on the user's behalf.
When a tool needs the user's GolfNow or Sweetgreen account, the bot drops an auth link into the thread. Tokens are stored per user, scoped per provider.
Every bot is pinned to its own number on Loki Messages. Users add it as a contact and text it like a friend — no app to install.
Each conversation runs in its own isolated runtime with durable state. The bot remembers the thread without you wiring up storage.
Bots can schedule their own future messages — reminders, check-ins, and nudges that fire without an inbound trigger.
Add the bot to a group and it understands the room: it answers when addressed, stays quiet when it isn't, and never double-replies.
Per-bot rate limiting and cost tracking out of the box, so a chatty user can't surprise you on the invoice.
MCP catalog
Showtimes, theaters, and ticket deals. Your bot finds the 7pm screening and the discount in one turn.
Menu, custom bowls, rewards, and order-ahead. "The usual, 12:30" becomes a placed order.
Tee-time search and booking with the user's own account — OAuth and payment handled in the thread.
Account, cash advance, earnings, and gift cards — everyday money actions over text.
Point the bot at any MCP endpoint you run. Tools show up automatically — no plugin format, no review queue.
The catalog grows where conversations want to go: dining, travel, tickets. Tell us what your bot needs.
How it works
Define who the bot is, what it can promise, and where the lines are. Pick the model that fits your latency and cost budget.
Choose from the catalog or point at your own MCP endpoint. Tools show up to the bot automatically, auth flows included.
We pin the bot to a phone number on Loki Messages. Share the contact — every text from a user becomes a conversation.
What people build
Finance
Connect accounts once, then ask anything: spending this week, the biggest expense, what's safe to spend. Answers in seconds, in the thread.
You spent $127 on food this week — 12% less than last. 📉Hospitality
Takes reservations, answers menu questions, and never promises what the kitchen can't. The host stand that answers at midnight.
Done — 7:30pm under your number. Want the quiet back room? 🪑Food
Knows the menu, remembers the usual, surfaces the deals. From craving to confirmed order without opening an app.
Your usual bowl + the free-delivery deal. Order it? 👍Commerce
Browse products, check limits, manage payments — guided purchasing over text, with the catalog as a conversation.
AirPods Pro — $24.90/mo over 10 months. Add to cart?Leisure
Movies, tee times, tables — one bot with three MCP servers becomes the friend who always knows what's on.
Dune 9:40pm + ramen after. Want me to book both? 🎬Yours
If you can write the system prompt and stand up (or pick) the tools, Loki Chat turns it into a contact people text.
Hey! I'm live — text me anything to get started ✨Beside, our consumer concierge, is a Loki Chat bot — same runtime, same MCP servers, same number-per-bot architecture we hand to you.

FAQ
No. Inference, conversation state, scheduling, and message delivery all run on our infrastructure. You provide a system prompt and configuration — and optionally your own MCP server, hosted wherever you like.
Claude models from Anthropic, GPT models from OpenAI, and open models running on Cloudflare Workers AI. The model is a per-bot setting, so you can prototype cheap and ship premium — or the reverse.
Through MCP — the open Model Context Protocol. Connect servers from our catalog (Fandango, Sweetgreen, GolfNow, Super) or any endpoint you run, and their tools become available to the bot's reasoning loop automatically.
The bot sends an OAuth link directly in the conversation. The user taps, signs in with the provider, and comes back to the thread. Tokens are stored per user and per provider — one user's login never bleeds into another's.
Yes. The bot understands group dynamics: it responds when addressed or clearly useful, stays quiet otherwise, and coordinates so it never sends twice for one message.
It can schedule its own future messages — reminders, check-ins, follow-ups — that fire without an inbound trigger. Proactive, but anchored to conversations users started.
Loki Messages is the transport: a REST API for sending and receiving iMessage. Loki Chat is the managed agent on top — we run the model, the tools, and the memory, and use Loki Messages for delivery. If you want to build your own bot logic, use Messages; if you want a bot from a prompt, use Chat.
