Adding to an Existing Project

You can add Mastra to an existing project using the CLI:

npm install -g mastra@latest 
mastra init

pnpm add -g mastra@latest
mastra init

yarn global add mastra@latest
mastra init

bun add --global mastra@latest
mastra init

Changes made to project:

1. Creates src/mastra directory with entry point
2. Adds required dependencies
3. Configures TypeScript compiler options

Interactive Setup

Running commands without arguments starts a CLI prompt for:

1. Component selection
2. LLM provider configuration
3. API key setup
4. Example code inclusion

Non-Interactive Setup

To initialize mastra in non-interactive mode use the following command arguments:

Arguments:
  --components     Specify components: agents, tools, workflows
  --llm            LLM provider: openai, anthropic, groq, google or cerebras
  --llm-api-key    Provider API key
  --example        Include example implementation
  --dir            Directory for Mastra files (defaults to src/)
