Pipelex features

  • Declarative MTHDS language. Write typed AI methods in a Dockerfile/SQL-like syntax that defines steps, inputs, and outputs.
  • Agent plugins. Claude Code and Codex plugins let agents design, run, and save methods directly from the IDE.
  • Multi-environment execution. Run methods as a chatbot MCP, a webapp, or via API/CLI on any infrastructure.
  • Open standard runtime. Pipelex runtime executes methods locally or in Docker, handling model routing and structured output.
  • SDKs and integrations. TypeScript (@pipelex/sdk) and Python (pipelex-sdk) clients generate typed calls to the Pipelex API.
  • VS Code extension. Provides syntax highlighting, linting, and formatting for .mthds files.
