What the publisher says
From the Calypso Multimodal RAG MCP repository's README, as published. We do not edit it. Read it on GitHub
Calypso MCP Server
Hosted multimodal RAG for Claude Desktop, Cursor, and agent workflows — in one npx command.
Ask questions across PDFs, screenshots, charts, and diagrams, and upload new source material, without running a vector store, a Docker stack, or an OCR pipeline. Answers come back with citations you can check.
This server is a Calypso Context surface — the same knowledge layer that backs Calypso on WhatsApp, exposed to MCP clients. How the pieces fit →
- One-command setup: npx -y @calypsohq/multimodal-rag-mcp-server --api-key sk-your-key-here
- True multimodal RAG: handles text and visuals natively through Gemini File Search
- Upload and query: dedicated tools for durable knowledge files and batch uploads
- Multi-turn conversations: context-aware answers with /new reset
- Discoverable workflows: resources and prompts for safe RAG, upload, and ingestion flows

Instead of wiring each agent or workflow to a one-off document search stack, use this MCP as the agent-facing entry point to one reusable answer layer: upload source material once, retrieve across text and visual content, and return answers with evidence users can verify.
Quick Start
# One-liner with npx
npx -y @calypsohq/multimodal-rag-mcp-server --api-key "sk-your-key-here"Or with environment variables:
CALYPSO_API_KEY="sk-..." npx -y @calypsohq/multimodal-rag-mcp-serverThen add the same command to Claude Desktop, Cursor, or Smithery using the configuration examples below.
Why Choose Calypso
No local vector store, no Docker Compose, and no separate OCR or vision pipeline before an agent can ask a grounded question. Point the server at a Calypso API key and it discovers your team's agents and knowledge buckets on connect.
- Zero infrastructure: one npx command; nothing to host or operate.
- Multimodal without a second pipeline: text and visuals are indexed together, so a chart or a screenshot is queryable the same way a paragraph is.
- Answers carry evidence: responses include source references and retrieval metadata.
- Read and write: query knowledge and add to it — files, batches, and websites — from the same server.
