Tool Integration Platforms
Use Composio with LangChain
Composio connects to LangChain through a official adapter package path (Composio integration listed in the LangChain tool integrations index). This page records what that connection looks like and links the evidence behind it.
Pairing facts
Why this pairing
Tool platform for AI agents with pre-authenticated toolkits, per-user sessions, managed authentication, triggers, and a sandboxed workbench across a large app catalog.
Best for: Agent apps that need many SaaS tools with per-user OAuth, API key handling, tool search, triggers, and framework adapters, without building each integration and auth flow from scratch.
Not ideal for: Teams that need raw isolated Linux computers for arbitrary code execution as the primary primitive, or that want to self-host the whole integration platform under a permissive license with no hosted dependency.
Configuration
tools = [<composio_toolset>]Source: https://docs.langchain.com/oss/python/integrations/tools. Examples use placeholders only.
Evidence
The LangChain tool integrations index lists Composio under integration platforms with 500 plus integrations, OAuth handling and event driven workflows, and also lists Composio in all tools.

Compatibility here means the cited page documents the pairing. It does not mean AgentsUse benchmarked the combination or that every version works unchanged. Pin versions, run the tool on a small job first, and review the first outputs before widening access.
Watch for
- The free tier is an included allowance, not unlimited use. Past the included amounts, tool calls, triggers, managed app usage, and Instant Tools can bill separately by mode.
- Composio-managed apps have lower allowances and count toward free tier limits on the pricing page, which advises using your own OAuth app for scaling.
- The platform is hosted and session centric. Teams wanting a fully self-hosted integration runtime or raw sandbox computers will find the model opinionated.
