Building AI Agents with Composio SDK

This skill provides comprehensive guidance for building AI agents using Composio SDK with various provider frameworks.

Overview

Composio integrates with 10+ major AI agent frameworks, allowing you to add tools and external integrations to your agents. Each framework-specific skill provides:

• Installing and setting up the provider SDK
• Finding latest SDK versions (NPM/PyPI)
• Official documentation links and latest examples
• Code examples for building agents with Composio tools
• Best practices and troubleshooting tips

Installing Composio Packages

Working in Composio SDK Repository (This Workspace)

If you're working within the Composio SDK repository itself, install packages from the workspace:

TypeScript:

pnpm i @composio/core @composio/<provider> --workspace

Example:

pnpm i @composio/core @composio/openai --workspace

External Projects (Outside SDK Repository)

For projects outside the Composio SDK repository, install from NPM/PyPI:

TypeScript:

npm install @composio/core @composio/<provider>

Python:

pip install composio-<provider>
# or
uv pip install composio-<provider>

Examples:

# TypeScript
npm install @composio/core @composio/openai

# Python
pip install composio-openai

Finding Latest SDK Versions

Each skill includes commands to find the latest versions of both Composio packages and provider SDKs.

Find Latest Composio Package Version

NPM (TypeScript):

npm view @composio/<provider> version
# Example
npm view @composio/openai version

PyPI (Python):

pip index versions composio-<provider> | grep "Available versions" | head -1
# Example
pip index versions composio-openai | grep "Available versions" | head -1

Find Latest Provider SDK Version

NPM (TypeScript):

npm view <provider-package> version
# Example
npm view openai version

PyPI (Python):

pip index versions <provider-package> | grep "Available versions" | head -1
# Example
pip index versions openai | grep "Available versions" | head -1

Tool Router vs Direct Tools

Composio SDK supports two integration methods based on the provider type:

🤖 Agentic Providers (Tool Router ONLY)

These frameworks support full modifier capabilities and MUST use Tool Router for user-isolated sessions:

Tool Router Benefits:

• ✅ User Isolation: Each user gets their own tool session
• ✅ Auto-Authentication: In-chat OAuth flows
• ✅ Scoped Access: Control toolkits per user
• ✅ Connection Management: Automatic OAuth handling
• ✅ Production Ready: Built for multi-user applications

📦 Non-Agentic Providers (Direct Tools)

These providers only support schema modifiers and use direct tools approach:

Direct Tools Characteristics:

• ✅ Simpler for single-user apps
• ✅ No session management needed
• ⚠️ Not suitable for multi-user production apps
• ⚠️ Manual authentication required

Tool Router Quick Start

import { Composio } from '@composio/core';
import { OpenAI } from 'openai';

const composio = new Composio();
const openai = new OpenAI();

async function runAgent(userId: string, prompt: string) {
  // Create isolated session for user
  const session = await composio.create(userId, {
    toolkits: ['github'],
    manageConnections: true  // Enable auto-authentication
  });

  // Get tools from session
  const tools = await session.tools();

  // Use with OpenAI
  const response = await openai.chat.completions.create({
    model: 'gpt-4o',
    messages: [{ role: 'user', content: prompt }],
    tools: tools,
  });

  // Handle tool calls
  if (response.choices[0].message.tool_calls) {
    const result = await composio.provider.handleToolCalls(userId, response);
    return result;
  }
}

// Each user gets isolated tools
await runAgent('user_123', 'Create a GitHub issue');
await runAgent('user_456', 'Check my Gmail');  // Different user, different session

Tool Router with Framework Integration

Each framework skill includes Tool Router examples. See:

• /building-agents-using-openai - Tool Router with OpenAI
• /building-agents-using-anthropic - Tool Router with Codex
• /building-agents-using-vercel - Tool Router with Vercel AI SDK
• And all other framework skills

Quick Start Example

Here's a quick example using OpenAI with direct tools (single-user):

TypeScript

import { Composio } from '@composio/core';
import { OpenAI } from 'openai';

const openai = new OpenAI({ apiKey: process.env.OPENAI_API_KEY });
const composio = new Composio({ apiKey: process.env.COMPOSIO_API_KEY });

// Get tools
const tools = await composio.tools.get('default', { toolkits: ['github'] });

// Use with OpenAI
const response = await openai.chat.completions.create({
  model: 'gpt-4o',
  messages: [{ role: 'user', content: 'Create a GitHub issue' }],
  tools: tools,
});

// Handle tool calls
if (response.choices[0].message.tool_calls) {
  const result = await composio.provider.handleToolCalls('default', response);
  console.log(result);
}

Python

from composio_openai import ComposioToolSet, Action
from openai import OpenAI

openai_client = OpenAI(api_key="YOUR_OPENAI_KEY")
composio_toolset = ComposioToolSet(api_key="YOUR_COMPOSIO_KEY")

# Get tools
tools = composio_toolset.get_tools(actions=[Action.GITHUB_CREATE_ISSUE])

# Use with OpenAI
response = openai_client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "Create a GitHub issue"}],
    tools=tools,
)

# Handle tool calls
result = composio_toolset.handle_tool_calls(response)

Provider Comparison

Common Composio Features

All frameworks support these Composio features:

1. Tool Management

// Get tools by app
const tools = await composio.tools.get('default', { apps: ['github', 'slack'] });

// Get specific actions
const tools = await composio.tools.get('default', { actions: ['GITHUB_CREATE_ISSUE'] });

// Get by toolkit
const tools = await composio.tools.get('default', { toolkits: ['github'] });

2. Connected Accounts

// Manage user integrations
const account = await composio.connectedAccounts.initiate({
  integrationId: 'github',
  entityId: 'user-123',
});

3. Custom Tools

import { experimental_createTool } from '@composio/core';
import { z } from 'zod';

// Custom tools are session-scoped: define a local tool, then attach it
// when creating a Tool Router session.
const myTool = experimental_createTool('MY_TOOL', {
  name: 'My Tool',
  description: 'Tool description',
  inputParams: z.object({ param: z.string() }),
  execute: async input => ({ result: input.param }),
});

const session = await composio.create('user-id', {
  experimental: { customTools: [myTool] },
});
