# **Connect grounded answers to every surface. **

Calypso Integrations move knowledge into Buckets and answers out through agents, APIs, widgets, MCP clients, n8n workflows, and product UI.

**Website**

## **Launch a source-grounded answer widget**

Give visitors a polished chat surface that answers from selected Buckets and shows citations without building a RAG frontend from scratch.

**API**

## **Call agents through an OpenAI-compatible interface**

Use familiar responses-style calls with hosted Calypso Agents, scoped bucket memory, and source metadata returned with answers.

**MCP**

## **Let AI clients upload and retrieve knowledge**

Connect MCP-aware tools and local agents to bucket-backed ingestion flows so knowledge can move from workspaces into retrieval.

**n8n**

## **Put grounded answers inside automations**

Route tickets, forms, documents, and workflow events through Calypso Agents for reusable retrieval in operations flows.

**API workflow **

## **One call pattern, every grounded answer surface. **
