A marketplace of ready-to-use APIs and MCP servers for apps and AI agents
Listed APIs speak the Model Context Protocol, so they can be attached as tools to AI agents and used by MCP-capable clients like Cursor, Claude Desktop and Continue.
Test endpoints live against models such as Claude and GPT to see how an API behaves in an actual agent-driven conversation before you commit to an integration.
Register a base URL and credentials, define inputs and outputs with a guided wizard, and deploy an MCP server that serves both humans and agents.
API Hub handles hosting, subscriptions, billing and revenue sharing, so API owners can focus on the product instead of payment plumbing.
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.
