Composio

Overview

Composio is a developer platform and tool-integration infrastructure that gives AI agents secure, production-ready access to over 1,000 external tools and applications. It serves as the action layer for LLMs and agent harnesses such as Claude, Codex, Cursor, OpenClaw, and Hermes, providing SDKs, tool execution, authentication, and sandboxed environments. By combining managed tool connectivity with just-in-time tool calls, Composio enables agents to move beyond chat and take real action across the software stack — from Gmail and Slack to GitHub, Salesforce, Notion, and hundreds of other SaaS tools.

At the core of Composio is a suite of execution and intelligence capabilities. Its smart tool resolution selects the right tools by intent rather than static configuration, with proposed execution plans and built-in guardrails for complex workflows. The platform's managed auth handles OAuth, API keys, token refresh, and lifecycle management end-to-end, with granular permission scoping triggered by user intent. Dynamic sandboxes provide secure, ephemeral remote environments where tools run as code, multi-step workflows and sub-LLM invocations execute reliably, and large responses are stored on navigable filesystems. Context-aware sessions preserve sandbox state, files, and progress, so agents never start from scratch. The MCP Gateway offers one managed Model Context Protocol endpoint to unify tools and agents, while triggers enable bidirectional communication that keeps agent state current. Additionally, the CLI lets developers add tools and auth to a coding agent with a single command.

Composio is model- and framework-agnostic, allowing teams to swap models based on cost or capability without reworking tools or auth configurations. It is built for scale and trust, with enterprise-grade controls including SSO, governance, audit logs, and fine-grained data access controls. Organizations can deploy with SOC 2 and ISO 27001:2022 compliance, and choose bring-your-own-cloud infrastructure. The platform's tool definitions evolve continuously, grounded in millions of real-world tool calls, and are optimized for each team's account-level usage patterns.

Use cases span every major business function: sales automation, marketing campaign management, engineering triage, customer support operations, HR and recruiting workflows, finance and ops reconciliation, e-commerce operations, and content production. From one-prompt workflows to five-line code integration, Composio turns any AI agent into a general-purpose executor, making automation practical, secure, and immediately deployable for startups and enterprises alike.

Core capabilities

1,000+ Integrations

One-click access to a broad catalog of tools and apps including Gmail, Slack, Notion, GitHub, Salesforce, and more, with just-in-time tool calls.

Managed Auth

End-to-end OAuth, API key, token refresh, and lifecycle management handled automatically, with granular permission scoping.

Smart Tools

Tools are resolved by intent rather than static configuration, with proposed execution plans and built-in guardrails for complex workflows.

Dynamic Sandbox

Remote, ephemeral, isolated sandbox environments that run tools as code, store large outputs on a navigable filesystem, and support multi-step workflows.

MCP Gateway

A single managed Model Context Protocol endpoint for all tools and agents, enabling seamless integration with MCP-compatible clients like Claude Code and Cursor.

Context-Aware Sessions

Sessions keep full context — sandbox state, files, and progress — so agents resume work without starting from scratch.

Model & Framework Agnostic

Swap LLMs and frameworks freely without reconfiguring tools or auth; works with Gemini, Claude, Codex, and other models.

Enterprise Security & Governance

SSO, audit controls, fine-grained data access controls, SOC 2 and ISO 27001:2022 compliance, and bring-your-own-cloud deployment.
