---title: "Introduction"description: "A local-first execution environment for AI agents."--- `executor` is a local-first execution environment for AI agents. It gives an agent a TypeScript runtime, a discoverable tool catalog, and a single local place to connect external systems such as MCP servers, OpenAPI APIs, and GraphQL APIs. This docs site is split into two documentation surfaces: - product-facing docs for how to install and use executor- developer-facing docs for how executor is built and how to extend it The product-facing section will come later. The current docs start with the developer-facing architecture and implementation model. If you are trying to understand the current system shape, start with: - [Control Plane](/developer/overview)- [CLI](/developer/cli)- [MCP](/developer/mcp)- [Code Mode](/developer/codemode)
