Your agent decides
what to do.
We handle the rest.
Just-in-time tool calls, secure delegated auth, sandboxed environments, and parallel execution across 1,000+ apps.

)Your agents are smart.
Their tools should be too.
Search that thinks
Save your agent's context for what matters. Only give it the right tools, at the right time.
Tools resolved by intent, not configuration
Proposed execution plans for complex workflows
Built-in guardrails so your agent gets it right the first time
Auto-Fix AgentTools that learn
Your tools get sharper every day. Real agent behavior at scale is what makes Composio tools the most accurate available.
Accuracy driven by millions of real-world tool calls
Account-level optimization for your usage patterns
API-stable, agent-optimized
Auth that works
Stop debugging auth flows. Composio handles OAuth end-to-end: on the fly, scoped to exactly what your agent needs.
Fully managed OAuth for every connector, out of the box
Inline auth triggered by user intent, not pre-configured
Granular permission scoping that tightens as you go

)Programmatic execution
Remote sandboxed environments where tools run as code and results live in a navigable filesystem.
Compose tools as code. Multi-step workflows, sub-LLM invocations
Large responses stored on a remote filesystem your agent can browse
Secure, ephemeral sandboxes for every execution
One product, every workflow
Turn Claude Code, Cursor, or any MCP client into an agent that executes across all your apps. Go from asking questions to doing work.
Every tool comes production-ready β authenticated, optimized, and reliable. No setup required.
Your agent has the intelligence. Now let it execute. Go from chatbot to general-purpose agent in five lines of code.
