## Summary - write CLI user data, pending login sessions, and agent identities through one atomic `0600` helper - repair `0644` credential files created by older CLI versions before reading them - redact credential-shaped structured values from CLI user-context diagnostics - redact secret-shaped text at both TypeScript and Python SDK log-output boundaries, including Pusher `auth` responses and exception tracebacks - preserve Python logger compatibility: errors remain untruncated, disabled levels remain lazy, and malformed placeholders cannot expose arguments ## Local reproduction Under the normal `022` umask, `next` created a plaintext credential file with mode `0644`. The pre-fix CLI user-context and TypeScript SDK debug paths also emitted sentinel credentials. The private atomic writer changes an existing `0644` target to `0600`, and the upgrade tests now prove all three legacy credential files are tightened without changing their contents. ## Verification - CLI permission upgrade tests: 31 passed across user data, pending login, and agent identity paths - CLI source and test typechecks passed - TypeScript core logging, redaction, and Pusher tests: 17 passed - TypeScript core source and type-test typechecks passed - Python logging regression tests: 5 passed - focused Ruff, Prettier, Oxlint, and `git diff --check` passed The focused CLI runner needed a temporary local alias for the pre-existing missing `#ssrf_guard` mapping in the CLI Vitest config. The alias was removed after verification and is not part of this PR. ## Contributor context Credit to **Syed Anas Mohiuddin**, independent security researcher, for reporting the legacy CLI credential-file permission issue. Supersedes [#4300](https://github.com/ComposioHQ/composio/pull/4300) · [Glen review](https://app.tryglen.com/ComposioHQ/composio/pull/4300). The implementation also covers agent credentials, retains atomic writes, and applies redaction at the shared SDK logging boundary.

Composio
Composio gives your AI agents 1000+ pre-authenticated toolkits, per-user sessions, authentication, triggers, and a sandbox, so you can ship agents that turn intent into action.
This is the Composio SDK monorepo. It contains:
@composio/core: TypeScript SDKcomposio: Python SDKcomposioCLI: search, execute, and script tools from your shell- Provider adapters for OpenAI Agents, Claude Agent SDK, Vercel AI SDK, LangChain, and more
Quickstart
Create a session for a user, hand its tools to your agent, and let the agent take action across 1000+ apps. Grab a COMPOSIO_API_KEY from the dashboard first.
TypeScript
npm install @composio/core @composio/openai-agents @openai/agents
@composio/coreintentionally packages its TypeScript source and SDK docs so the installed package is inspectable to coding agents. If you want a smaller install with the same API, use@composio/slim.
import { Composio } from "@composio/core";
import { OpenAIAgentsProvider } from "@composio/openai-agents";
import { Agent, run } from "@openai/agents";
const composio = new Composio({ provider: new OpenAIAgentsProvider() });
// Each session is scoped to one of your users
const session = await composio.create("user_123");
const tools = await session.tools();
const agent = new Agent({
name: "Personal Assistant",
instructions: "You are a helpful assistant. Use Composio tools to take action.",
tools,
});
const result = await run(agent, "Summarize my emails from today");
console.log(result.finalOutput);
Python
pip install composio composio-openai-agents openai-agents
from composio import Composio
from composio_openai_agents import OpenAIAgentsProvider
from agents import Agent, Runner
composio = Composio(provider=OpenAIAgentsProvider())
# Each session is scoped to one of your users
session = composio.create(user_id="user_123")
tools = session.tools()
agent = Agent(
name="Personal Assistant",
instructions="You are a helpful assistant. Use Composio tools to take action.",
tools=tools,
)
result = Runner.run_sync(starting_agent=agent, input="Summarize my emails from today")
print(result.final_output)
By default a session gets meta tools that discover, authenticate, and execute app tools at runtime, so you don't load hundreds of tool definitions into context. Store session.session_id and reuse it with composio.use() across turns. See what a session is and configuring sessions for restricting toolkits, auth configs, and connected accounts.
Prefer MCP? Every session also exposes a hosted MCP endpoint. Pass mcp: true to composio.create() and point Claude, Cursor, or any MCP client at session.mcp.url. See sessions via MCP.
CLI
The composio CLI runs Composio from your shell and gives coding agents like Claude Code a local tool surface.
curl -fsSL https://composio.dev/install | sh
The installer puts composio on your PATH for future terminals. Open a new terminal, then run composio login. See INSTALL.md for shell setup overrides, including COMPOSIO_INSTALL_SHELL=none for install-only runs.
Use composio search to find tools, composio execute to run them, composio link to connect accounts, and composio run to script workflows in TypeScript. See the CLI docs.
Providers
A provider adapts Composio tools to your agent framework's native tool format:
| Provider | TypeScript | Python |
|---|---|---|
| OpenAI | @composio/openai |
composio-openai |
| OpenAI Agents | @composio/openai-agents |
composio-openai-agents |
| Anthropic | @composio/anthropic |
composio-anthropic |
| Claude Agent SDK | @composio/claude-agent-sdk |
composio-claude-agent-sdk |
| Vercel AI SDK | @composio/vercel |

| Google GenAI | @composio/google |
composio-gemini, composio-google |
| Google ADK | — | composio-google-adk |
| LangChain | @composio/langchain |
composio-langchain |
| LangGraph | via @composio/langchain |
composio-langgraph |
| LlamaIndex | @composio/llamaindex |
composio-llamaindex |
| Mastra | @composio/mastra |

| Pi | @composio/experimental* |
— |
| Cloudflare Workers AI | @composio/cloudflare |
