The easiest hosted multimodal RAG MCP server for Claude Desktop, Cursor, and agent workflows.
One npx command. Gemini File Search-powered. Handles PDFs, screenshots, charts, diagrams, and images natively with verifiable citations.
The easiest way to add hosted multimodal RAG to Claude, Cursor, Windsurf, and custom agents.
npx -y @calypsohq/multimodal-rag-mcp-server --api-key sk-your-key-here/new resetGitHub | Docs | Smithery | Official MCP Registry
Tags: multimodal-rag, easiest-mcp-rag, gemini-rag, hosted-rag-mcp, mcp-server
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.
# 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-server
Then add the same command to Claude Desktop, Cursor, or Smithery using the configuration examples below.
Calypso is built for teams that want the easiest hosted multimodal RAG MCP server: no local vector stack, no Docker compose, and no custom OCR or image-processing pipeline before agents can ask grounded questions.
