Liquid
Connect your AI agent to anything — with no connector to write or maintain.
Point Liquid at a URL or a database and it works out the interface for you:
discovers its shape, maps it to the fields you asked for, and handles auth,
pagination and normalization — typed records, no client code. When the upstream
drifts, it re-maps and keeps going. The same small API — fetch · query ·
write · sense — reaches web APIs, databases, other agents (MCP/A2A), email,
and even IoT and industrial systems (MQTT, Modbus, OPC UA, BACnet). An LLM does the
learning at setup (and on drift); the data path itself makes no model call.
What an agent can reach through Liquid
One agent-facing API (fetch · query · write · sense) over everything an
agent might need to touch — Liquid figures out how to talk to it so the agent
doesn't have to. It's the agent's senses and hands: fetch/query probe,
sense perceives a live event stream, write acts on the world.
- Web APIs & messaging — REST/JSON, GraphQL, SOAP/WSDL, gRPC, WebSocket, SSE/NDJSON streams, MQTT (IoT pub/sub — subscribe to sense, publish to act)
- Email — IMAP/SMTP (any provider, app-password or OAuth2
XOAUTH2) and the Gmail API (OAuth2): read a mailbox,sensenew mail as it arrives, and send - Industrial / OT — Modbus (PLCs, sensors) and OPC UA (Industry-4.0 nodes, native subscriptions) for the factory floor; BACnet for buildings (HVAC/BMS) — read, write, and sense
- Android devices — phones, TV boxes, kiosks via ADB: sense
logcat, readshell, act withinput/am - Other agents & tools — any MCP server, A2A agents, ChatGPT-plugin manifests
- Databases — Postgres (+ pgvector), MySQL/MariaDB, SQLite, DuckDB, SQL Server, Neo4j (graph), MongoDB (documents), Redis (key-value)
- People, places & things — a human, a home, or a car as a node via
connectors: Telegram (perceive messages,sendreplies), Home Assistant (perceive a whole smart home's state changes, act viacall_service— lights, locks, media), and Smartcar (perceive a connected vehicle across ~30 brands — location/battery/fuel — and act:lock/unlock, charge)
