For developers
You can build your own agent with Composio
Composio’s Python and TypeScript SDKs connect your agent to apps and handle authentication and tool execution. Provider integrations adapt Composio tools to your chosen model API or framework:
Anthropic
Use Composio with the Claude Messages API or the Claude Agent SDK.
OpenAI
Use Composio with the Responses API, Chat Completions API, or OpenAI Agents SDK. For other OpenAI-compatible APIs, your provider must support the tool-calling format you use.
Vercel AI SDK
Add Composio tools with built-in execution so the AI SDK can run tool calls for you.
LangGraph
Use our official Python package to turn Composio tools into LangChain tools that work in LangGraph workflows.
Everything else
Composio works with any harness that supports remote MCP servers
Composio provides a hosted MCP server that gives your harness access to its app integrations. If your harness supports the ability to connect to remote MCP servers, you can connect it to Composio.
