Embedding Knowledge Cards

Here's a practical guide to using Tako with LlamaIndex to create a conversational AI agent:

LlamaIndex

This Python script sets up a basic [MCP (Model Context Protocol)](https://modelcontextprotocol.io/introduction) server integrated with Tako Knowledge Search API. The provided code creates an agent powered by MCP that uses Tako's Knowledge Search API to search for knowledge cards in response to user queries.

MCP Server

Create your MCP Server with Tako

Use Tako with MCP to create an agent that can answer questions about your data.

MCP with Notion

Integrate Tako MCP with Notion

MCP Remote Server

Tako Hosted MCP Servers

Use Tako knowledge cards to ground your AI chatbot

Vercel AI SDK

Integrate Tako into your chatbot

Add interactive knowledge cards to your AI chatbot

Next.js AI Chatbot

Integrating Tako Cards into a Vercel Next.js AI Chatbot

Tako is an embeddable, composable knowledge graph sourced exclusively from authoritative structured data. Our API takes natural language queries or faceted searches as an input and returns iframe URLs that render responsive, interactive visualizations.

Getting Started

Authentication

Retrieve a list of collections. Collections are the primitive Tako uses to group data. They are useful for performing faceted searches.
