Port of Context

Port of Context was born over coffee at 7th Avenue Donuts and Diner in Park Slope, Brooklyn. The founders were tired of developer-unfriendly AI agent building infrastructure and set off to build an alternative—for developers, by developers. Today Port of Context powered Goose, Prudential, and others.

Built in Rust, with a Python toolkit for converting native agent tools to Code Mode. What the agent sees is TypeScript that we generate from your tool definitions, type-check in under 100ms, and execute inside isolated Deno sandboxes. It speaks MCP, and plugs into LangChain, the Claude Agent SDK, CrewAI, the OpenAI Agents SDK, and Pydantic AI. MIT. Self-hosted. BYO-LLM.
