An all-in-one toolkit to build agentic applications that turn natural language into real-world actions.

Dexto is a universal agent interface for building agentic apps—software that understands natural language and takes real-world actions. It orchestrates LLMs, tools, and data into persistent, stateful systems with memory, so you can rapidly create AI assistants, copilots, and context-aware apps that think, act and feel alive.

• Autonomous Agents - Agents that plan, execute, and adapt to user goals.
• Digital Companions - AI assistants & copilots that remember context and anticipate needs.
• Multi-Agent Systems - Architect agents that collaborate, delegate, and solve complex tasks together.
• MCP Clients - Connect multiple tools, files, APIs, and data via MCP Servers.
• Agent-as-a-Service – Transform your existing SaaS products and APIs into dynamic, conversational experiences.
• Agentic Applications – Integrate Dexto as a reasoning engine to power interactive, multimodal, AI-native applications.

• Batteries Included – Session management, tool orchestration, multimodal support.
• 20+ LLMs – Instantly switch between OpenAI, Anthropic, Google, Groq, local models or bring your own.
• Run Anywhere – Local for privacy, cloud for reach, or hybrid. Same agent, any deployment.
• Native Multimodal – Text, images, files, and tools in a single conversation. Upload screenshots, ask questions, take actions.
• Persistent Sessions – Conversations, context, and memory are saved and can be exported, imported, or shared across environments.
• Flexible Interfaces – One agent, endless ways to interact: Ready to-use CLI, WebUI, APIs, or integrate with your own UI.
• Production Ready – Observability and error handling built-in.
• Tooling & MCP – Integrate 100+ tools and connect to external servers via the Model Context Protocol (MCP).
• Customizable Agents – Define agent behavior, tools, and prompts in YAML or TypeScript.
• Pluggable Storage – Use Redis, PostgreSQL, SQLite, in-memory, and more for cache and database backends.

# NPM global
npm install -g dexto

# —or— build from source
# this sets up dexto CLI from the cloned code
git clone https://github.com/truffle-ai/dexto.git
cd dexto && pnpm install && pnpm install-cli

# 1. Run setup workflow - this prompts for your preferred LLM and API keys and starts the interactive CLI
dexto

# 2. Try a multi-step task
dexto "create a snake game in HTML/CSS/JS, then open it in the browser"

# 3. Launch the Dexto Web UI
dexto --mode web

In 2 -> Dexto will use filesystem tools to write code and browser tools to open it — all from a single prompt. The Web UI allows you to navigate previous conversations and experiment with different models, tools and more.

dexto --auto-approve "refactor my project using the filesystem and browser tools"

Use the --auto-approve flag to bypass confirmation prompts when you trust the tools being invoked—perfect for fast local iteration. Remove the flag when you want explicit approval again.

Dexto comes with pre-built agent recipes for common use cases. Install and use them instantly:

# List available agents
dexto list-agents

# Install specific agents
dexto install nano-banana-agent podcast-agent

# Use an agent
dexto --agent nano-banana-agent "create a futuristic cityscape with flying cars"
dexto --agent podcast-agent "generate a podcast intro with two hosts discussing AI"

Available Agents:

• Nano Banana Agent – Advanced image generation and editing using Google's Nano Banana (Gemini 2.5 Flash Image)
• Podcast Agent – Advanced podcast generation using Google Gemini TTS for multi-speaker audio content
• Database Agent – Demo agent for SQL queries and database operations
• Image Editor Agent – Image editing and manipulation
• Music Agent – Music creation and audio processing
• PDF Agent – Document analysis and conversation
• Product Researcher – Product naming and branding research
• Triage Agent – Demo multi-agent customer support routing system

Each agent is pre-configured with the right tools, prompts, and LLM settings for its domain. No setup required—just install and start building.

More ready-to-run recipes live in agents/ and the docs site.

Task: Can you go to amazon and add some snacks to my cart? I like trail mix, cheetos and maybe surprise me with something else?

# Default agent has browser tools
dexto

Task: Detect all faces in this image and draw bounding boxes around them.

dexto --agent image-editor-agent

Task: Generate an intro for a podcast about the latest in AI.

dexto --agent podcast-agent

Task: Generate a photo of a baby panda.

You can add your own Model Context Protocol (MCP) servers to extend Dexto's capabilities with new tools or data sources. Just edit your agent YAML or add it directly in the WebUI.

Task: Create a snake game in HTML/CSS/JS, then open it in the browser

dexto "create a snake game in HTML/CSS/JS, then open it in the browser"

Task: Summarize emails and send highlights to Slack

dexto --agent ./agents/examples/email_slack.yml

Run dexto --help for all flags, sub-commands, and environment variables.

Dexto treats each configuration as a unique agent allowing you to define and save combinations of LLMs, servers, storage options, etc. based on your needs for easy portability. Define agents in version-controlled YAML. Change the file, reload, and chat—state, memory, and tools update automatically.

# agents/my-agent.yml
llm:
  provider: openai
  model: gpt-4.1-mini
  apiKey: $OPENAI_API_KEY

mcpServers:
  filesystem:
    type: stdio
    command: npx
    args: ['-y', '@modelcontextprotocol/server-filesystem', '.']
  web:
    type: stdio
    command: npx
    args: ['-y', '@modelcontextprotocol/server-brave-search']

systemPrompt: |
  You are a helpful AI assistant with access to files and web search.

Switch between providers instantly—no code changes required.

# Switch models via CLI
dexto -m claude-sonnet-4-5-20250929
dexto -m gemini-2.5-pro

See our Configuration Guide for complete setup instructions.

Install the @dexto/core library, and build applications with the DextoAgent class. Everything the CLI can do, your code can too.

npm install @dexto/core

import { DextoAgent } from '@dexto/core';

// Create and start agent
const agent = new DextoAgent({
  llm: {
    provider: 'openai',
    model: 'gpt-4.1-mini',
    apiKey: process.env.OPENAI_API_KEY
  }
});
await agent.start();

// Run tasks
const response = await agent.run('List the 5 largest files in this repo');
console.log(response);

// Hold conversations
await agent.run('Write a haiku about TypeScript');
await agent.run('Make it funnier');

await agent.stop();

See our TypeScript SDK docs for complete examples with MCP tools, sessions, and advanced features.

Create and manage multiple conversation sessions with persistent storage.

const agent = new DextoAgent(config);
await agent.start();

// Create and manage sessions
const session = await agent.createSession('user-123');
await agent.run('Hello, how can you help me?', undefined, 'user-123');

// List and manage sessions
const sessions = await agent.listSessions();
const sessionHistory = await agent.getSessionHistory('user-123');
await agent.deleteSession('user-123');

// Search across conversations
const results = await agent.searchMessages('bug fix', { limit: 10 });

Switch between models and providers dynamically.

// Get current configuration
const currentLLM = agent.getCurrentLLMConfig();

// Switch models (provider inferred automatically)
await agent.switchLLM({ model: 'gpt-4.1-mini' });
await agent.switchLLM({ model: 'claude-sonnet-4-5-20250929' });

// Switch model for a specific session id 1234
await agent.switchLLM({ model: 'gpt-4.1-mini' }, '1234')

// Get supported providers and models
const providers = agent.getSupportedProviders();
const models = agent.getSupportedModels();
const openaiModels = agent.getSupportedModelsForProvider('openai');

For advanced MCP server management, use the MCPManager directly.

import { MCPManager } from '@dexto/core';

const manager = new MCPManager();

// Connect to MCP servers
await manager.connectServer('filesystem', {
  type: 'stdio',
  command: 'npx',
  args: ['-y', '@modelcontextprotocol/server-filesystem', '.']
});

// Access tools, prompts, and resources
const tools = await manager.getAllTools();
const prompts = await manager.getAllPrompts();
const resources = await manager.getAllResources();

// Execute tools
const result = await manager.executeTool('readFile', { path: './README.md' });

await manager.disconnectAll();

Configure storage backends for production-ready persistence and caching.

# agents/production-agent.yml
storage:
  cache:
    type: redis
    url: $REDIS_URL
    maxConnections: 100
  database:
    type: postgres
    connectionString: $POSTGRES_CONNECTION_STRING
    maxConnections: 25

sessions:
  maxSessions: 1000
  sessionTTL: 86400000 # 24 hours

Supported Backends:

• Cache: Redis, In-Memory (fast, ephemeral)
• Database: PostgreSQL, SQLite, In-Memory (persistent, reliable)

Use Cases:

• Development: In-memory for quick testing
• Production: Redis + PostgreSQL for scale
• Simple: SQLite for single-instance persistence

See the DextoAgent API Documentation for complete method references.
