composio-claude-agent-sdk 0.18.1

Use Composio to get an array of tools with Claude Code Agents SDK.

composio-claude-agent-sdk

Adapts Composio tools to the Claude Agent SDK, exposing them to Claude through an in-process MCP server.

Installation

pip install composio composio-claude-agent-sdk claude-agent-sdk

The Claude Agent SDK also requires the Claude Code CLI: npm install -g @anthropic-ai/claude-code.

Set COMPOSIO_API_KEY (from the dashboard) and ANTHROPIC_API_KEY in your environment.

Quickstart

import asyncio

from composio import Composio
from composio_claude_agent_sdk import ClaudeAgentSDKProvider
from claude_agent_sdk import (
    AssistantMessage,
    ClaudeAgentOptions,
    TextBlock,
    create_sdk_mcp_server,
    query,
)

composio = Composio(provider=ClaudeAgentSDKProvider())

# Each session is scoped to one of your users
session = composio.create(user_id="user_123")
tools = session.tools()

server = create_sdk_mcp_server(name="composio", version="1.0.0", tools=tools)


async def main():
    options = ClaudeAgentOptions(
        system_prompt="You are a helpful assistant. Use tools to complete tasks.",
        permission_mode="bypassPermissions",
        mcp_servers={"composio": server},
    )
    async for message in query(prompt="Summarize my emails from today", options=options):
        if isinstance(message, AssistantMessage):
            for block in message.content:
                if isinstance(block, TextBlock):
                    print(block.text)


asyncio.run(main())

For multi-turn use, store session.session_id and reuse it with composio.use(session_id) instead of calling create() again.

How tools are exposed

session.tools() returns SdkMcpTool objects that plug straight into create_sdk_mcp_server. The provider also ships composio.provider.create_mcp_server(tools) if you prefer a preconfigured server (name composio, customizable via ClaudeAgentSDKProvider(server_name=..., server_version=...)).
