LlamaIndex Provider

The LlamaIndex Provider transforms Composio tools into a format compatible with LlamaIndex's function calling capabilities.

Setup

pip install composio_llamaindex==0.8.0 llama-index

npm install @composio/llamaindex @llamaindex/openai @llamaindex/workflow

Usage

import asyncio
import dotenv
from composio_llamaindex import LlamaIndexProvider
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

from composio import Composio

# Load environment variables from .env
dotenv.load_dotenv()

# Setup client
llm = OpenAI(model="gpt-5")
composio = Composio(provider=LlamaIndexProvider())

tools = composio.tools.get(
    user_id="user@acme.com",
    tools=["GITHUB_STAR_A_REPOSITORY_FOR_THE_AUTHENTICATED_USER"],
)

workflow = FunctionAgent(
    tools=tools,
    llm=llm,
    system_prompt="You are an agent that performs github actions.",
)


async def main():
    result = await workflow.run(
        user_msg="Hello! I would like to star a repo composiohq/composio on GitHub"
    )
    print(result)


if __name__ == "__main__":
    asyncio.run(main())

import { Composio } from '@composio/core';
import { LlamaindexProvider } from '@composio/llamaindex';
import { openai } from '@llamaindex/openai';
import { agent } from '@llamaindex/workflow';
import 'dotenv/config';

// Initialize Composio with LlamaIndex provider
const composio = new Composio({
  apiKey: process.env.COMPOSIO_API_KEY,
  provider: new LlamaindexProvider(),
});

async function main() {
  // Get tools
  const tools = await composio.tools.get('user@acme.com', {
    tools: ['GITHUB_STAR_A_REPOSITORY_FOR_THE_AUTHENTICATED_USER'],
  });

  // Create LlamaIndex agent with Composio tools
  const githubAgent = agent({
    name: 'GitHub Agent',
    description: 'An agent that performs GitHub actions',
    llm: openai({ model: 'gpt-4o-mini' }),
    systemPrompt: 'You are an agent that performs github actions.',
    tools,
  });

  // Run the agent
  const result = await githubAgent.run(
    'Hello! I would like to star a repo composiohq/composio on GitHub'
  );

  console.log(result);
}

main().catch(console.error);

  );

  for await (const event of stream) {
    if (agentStreamEvent.include(event)) {
