Composio
AI InfrastructureFreemiumVisit Site
Gives agents authenticated access to 1,000+ applications, handling OAuth, tool selection, and sandboxed execution so you do not build integrations one at a time.
Overview
Every agent project hits the same wall at week three: the agent is fine, but connecting it to Gmail, Salesforce, Slack, Jira, and Notion means five OAuth implementations, five token refresh flows, and five sets of scope decisions. Composio makes that a dependency rather than a project. It handles delegated auth end to end, and — the part that matters more than the integration count — it selects relevant tools just-in-time based on agent intent rather than stuffing every tool definition into the context window, which is a direct fix for the accuracy collapse that happens when you hand a model 200 tools. It also provides sandboxed execution environments and parallel execution for multi-step work. It integrates with Claude Code, Cursor, and MCP clients generally. Free tier available; enterprise pricing via demo.
Pros & Cons
Pros
- Eliminates per-integration OAuth work across 1,000+ apps

- Real free tier for evaluation
Cons
- Paid pricing is not published
- Routing agent credentials through a third party needs a security review
- Another dependency in the critical path of every agent action
- Tool coverage depth varies by application
