What it does

Composio provides a sandboxed workbench for building AI agents that can turn intent into action, powering toolkits, tool search, context management, authentication, and more.

Install / run

git clone https://github.com/ComposioHQ/composio.git && cd composio

When to use it

•When you need to integrate multiple AI tools and services into a single workflow
•When you want to build custom AI agents with a sandboxed environment for testing and development
•When you require a flexible and scalable platform for managing AI-powered toolkits and workflows

Quick start

1Run `yarn` to install dependencies and build the project
2Start the Composio development server with `yarn start`
3Open the Composio workbench in your browser at `http://localhost:3000`
4Create a new AI agent by clicking on the 'Create Agent' button and following the setup wizard
5Configure your agent's toolkit and workflow by editing the `composio.json` file

Ready-to-paste prompt

Create a new AI agent with a sample toolkit by running `yarn create-agent --template=default`

Heads up: Make sure you have a compatible version of Node.js (14 or higher) and Yarn installed on your system, as Composio relies on these for building and running the workbench
