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.

Unified MCP Server features

  • Zero-storage architecture. Tool calls fetch data directly from source APIs; no data is cached or stored.
  • Authorization-first access. All tools require explicit customer authorization before they become callable.
  • Bi-directional actions. Agents can read and write data (e.g., update records) where the integration supports it.
  • Unified auth handling. OAuth, API-key flows, token refresh and optional embedded sign-in UI are provided out of the box.
  • Tool discovery controls. Scope available tools to fit model limits and reduce surface area.
  • SDKs & language support. Client SDKs for TypeScript, Python, PHP, Java, C#, Ruby, Go and UI components for React, Vue, Angular, JS.
  • Embedded security boundaries. Each connection defines isolated access, with read/write, object and action restrictions.
  • Virtual & native webhooks. Unlimited webhook subscriptions with virtual polling for systems lacking native webhooks.
