WHY COMPOSIO

## Your agents are smart.
Their tools should be too.

list sentry errors and create linear issuesresolving intent...

01

### 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

02

### Tools 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

Agent Chat

connected

Ask your agent something...

03

### 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

Fetch & triage errors

sandbox · py 3.11

issues = run_composio_tool(
  'SENTRY_LIST_ISSUES',
  project='api-prod',
  status='unresolved'
)

for issue in issues:
  issue['trace'] = run_composio_tool(
    'SENTRY_GET_EVENT',
    issue_id=issue['id']
  )

ranked = invoke_llm(
  f'Classify these {len(issues)} errors.'
  ' Return P0/P1/P2 with reasoning.'
)

for error in ranked['P0']:
  run_composio_tool(
    'LINEAR_CREATE_ISSUE',
    title=error['title'],
    team_id='ENG',
    priority=1
  )

04

### 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

ZERO CODE TO FULL CONTROL

## One product, every workflow

### Managed Auth

OAuth, API keys, token refresh, lifecycle management. We handle all of it so you never think about auth again.

[LEARN MORE](https://docs.composio.dev/docs/authentication?utm%5Fsource=landing-page&utm%5Fcampaign=sdk-managed-auth)

### Triggers

Bidirectional communication with your apps to keep your agents informed.

[LEARN MORE](https://docs.composio.dev/docs/triggers?utm%5Fsource=landing-page&utm%5Fcampaign=sdk-triggers)

### Context Aware Sessions

session.py

1session \= composio.create(user\_id\="user\_123")

2tools \= session.tools()

3connection \= session.authorize("github")

Every session carries full context — sandbox state, files, progress. Your agent never starts from scratch.

### Model & Framework Agnostic

Gemini

No lock-in. Swap models based on cost, capability, or use case. Your tools and auth carry over, zero rework.
