Zero Data Retention is here

Developers can now run covered tool calls and Proxy Execute requests without storing their request arguments, response data, or error text in Composio's execution logs. Logs still retain metadata. Zero Data Retention replaces the Don't store data setting and adds organization-wide controls alongside per-project settings.

• ZDR is available for an additional usage-based fee on paid plans and included on Enterprise. Admins can enable it across current projects or control it per project.
• ZDR applies to new calls. Existing logs remain subject to the standard retention policy.
• Read the full coverage details before enabling it. For more information on how Composio handles data retention, visit trust.composio.dev

For You

Shared Connections and Skills

Connect once, share with your team

Shared Connections let teammates use one connected account through their own agents, without each person authenticating separately. Share a connection to a team app, invite your teammates, and use the activity logs to see who's using it.

Save a workflow as a Skill

Skills let you save instructions for recurring tasks and share them with your team. For example, capture how you put together a weekly customer update so another teammate's agent can follow the same steps. Ask your agent to create a Skill, then search for and load it when you need it again.

Atomic Agent now connects to your apps with Composio

Atomic Agent is an open-source agent that runs on your machine and supports local models through llama.cpp. Add your Composio API key in its Integrations tab, then ask it to work across your apps. You can say "email this to the team" without choosing a tool first.

• The agent searches for the right tool, reads its schema, and asks you to connect an account when needed. Actions on your connected accounts follow Atomic Agent's approval policy.
• Local models handle inference on your machine. App authentication and tool execution run through Composio.

New tools and toolkits

The catalog now includes provider-hosted MCP servers alongside Composio-built toolkits, with options for Cloudflare, MongoDB, Grafana Cloud, and PostHog. September also brought about 60 new toolkits.

• NotebookLM and TikTok Ads also gained Composio-managed OAuth, so you can connect without registering your own OAuth app.
• Webhook triggers now cover 20+ apps, including Shopify, Jira, Stripe, Outlook, DocuSign, Monday, Calendly, Twilio, Trello, and Close. Composio handles provider registration and delivers signed events to your application's webhook endpoint.
• Filter Outlook triggers by importance, catch Slack thread replies, and subscribe to a webhook when a user's connection becomes active.

Webhook triggers are available on the Developer Platform. Build with webhook triggers.

Inside Yang, our toolkit software factory

APIs change, tools break, and agents need those tools to keep working. Yang builds and repairs Composio toolkits, puts review bots in front of human approval, and checks production telemetry after a fix ships. Our new engineering post walks through the system, including how Yang's coding-agent sessions survive failures and why a green CI run isn't the end of the job.

For builders

Even more for builders

• Shipped: More complete examples cover a CSV report agent, multiple accounts, custom tools, and an email-triggered agent. The docs now organize examples by complete agents, integration patterns, and deployment.
• Experimental access: Instant Tools let you run supported tools without connecting a provider account. Usage is billed to your Composio balance. Learn how to request access.
• Coming soon:
  • End-user MCP: give your users access to custom MCP servers with OAuth authentication
  • Governance improvements with Approval Mode: human-in-the-loop approval for sensitive tool calls

That's October's roundup. See you after the next batch ships.
