What Executor does

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.

What is your company going to make? Please describe your product and what it does or will do.

Executor is an open source MCP gateway that lets you sign in once to all your integrations and access them from any client. You can connect AI agents to anything - MCP, GraphQL, OpenAPI endpoints - using a unified management layer. This makes it easier to scale agent access to all your production services, data, and tools without wrestling with fragmented auth and integration mess.

Where do you live now, and where would the company be based after YC?

San Francisco, CA, USA. The company will stay based here after YC.

Explain your decision regarding location.

San Francisco is the center of AI and dev tool communities, with the most access to users, partners, and resources. Being here keeps us close to both early adopters and other builders.
