@composio/llamaindex
The LlamaIndex provider turns Composio tools into LlamaIndex tools that execute themselves, ready to hand to a LlamaIndex agent.
Installation
npm install @composio/core @composio/llamaindex @llamaindex/openai @llamaindex/workflow
Set COMPOSIO_API_KEY with your API key from the dashboard, and OPENAI_API_KEY (or your LLM provider's key).
Quickstart
Create a session for your user, fetch its tools, and hand them to an agent:
import { Composio } from '@composio/core';
import { LlamaindexProvider } from '@composio/llamaindex';
import { openai } from '@llamaindex/openai';
import { agent } from '@llamaindex/workflow';
const composio = new Composio({
provider: new LlamaindexProvider(),
});
// Create a session for your user
const session = await composio.create('user_123');
const tools = await session.tools();
const myAgent = agent({
llm: openai({ model: 'gpt-5.2' }),
tools,
});
const result = await myAgent.run(
"Send an email to john@example.com with the subject 'Hello' and body 'Hello from Composio!'"
);
console.log(result.data.result);
The provider converts each tool's JSON Schema parameters to Zod and wires execution through Composio, so LlamaIndex can call the tools directly.
