About Executor
Summary
Executor builds an MCP gateway that connects AI agents to any integration, whether OpenAPI, GraphQL, or MCP, through a single endpoint. Developers configure an integration once and every agent client gets access to it, replacing the repetitive per-client OAuth setup and API key management that multiplies across tools like Claude Code, Cursor, and Codex. At runtime, Executor surfaces only one tool to the model and fetches what it needs on demand, keeping context windows small regardless of how many services are connected.
Business model
Free for up to three people, with paid cloud plans above that tier.
Go-to-market
Developer teams building or scaling AI agents adopt Executor self-serve, starting on the cloud tier or running it on desktop, CLI, or self-hosted infrastructure.
From the Y Combinator listing
The open source integration management layer for AI.
Executor.sh is an MCP gateway that allows you to sign in once to all of your integrations and use them with any client. We enable you to connect your agents to anything (MCP, GraphQL, OpenAPI) so regardless of what you're trying to connect agents to you're able to. If you're trying to scale agents to access all of your production services, data, etc, you need Executor as a unified management layer.
