Give your AI agents secure, authenticated access to 1,700+ apps
A large catalog of pre-built integrations spanning productivity, CRM, support, engineering, finance, HR, and e-commerce apps, each exposing callable actions to your agent.
Composio runs OAuth flows, stores and refreshes credentials, and enforces per-action permission scopes so agents act only where you allow them.
One managed MCP endpoint that connects Claude, ChatGPT, Codex, Cursor, and other MCP clients to your entire tool catalog in a few clicks.
Start background agents from events occurring across connected apps, so work can begin without a user prompt.

Open-source AI gateway for LLM APIs, agents and MCP servers
Route requests to 100+ model APIs through unified protocol conversion, with model-level fallback and flexible backend scheduling.
Expose existing services as MCP servers, proxy and translate protocols, and apply authentication, traffic scheduling and parameter mapping to tool calls.
Track token consumption per consumer, enforce quotas on overuse, and cache exact or semantically similar answers to save tokens and reduce latency.
Protect privacy on data sent to external models and filter model output before it reaches users, alongside standard gateway auth and rate limiting.

SpecialistRobust TypeScript framework for agent workflows and tools, but requires writing custom integration code instead of pre-built connectors.

Powerful universal API infrastructure for connecting agents to B2B data, but focuses more on unified SaaS data than tool execution.

Excellent managed authentication and event triggers for agent workflows, but less specialized around native MCP gateway protocols.
