Port details
py-langchain-protocol Python bindings for the LangChain agent streaming protocol
0.0.20 misc Σ 0.0.19Version of this port present on the latest quarterly branch. Maintainer: yuri@FreeBSD.org Port Added: 2026-06-01 06:39:27Last Update: 2026-10-22 17:03:38Commit Hash: 36a464d Also Listed In: python License: MITWWW: https://github.com/langchain-ai/agent-protocol/tree/main/streaming https://github.com/langchain-ai/agent-protocol Description: # The LangChain Agent Protocol is a framework-agnostic specification for
serving Large Language Model (LLM) agents in production. It defines
standardized APIs for executing agents (Runs), managing multi-turn
interactions (Threads), and handling long-term memory (Store).
The protocol includes a thread-centric streaming layer for observing and
controlling live agent executions, featuring support for message deltas,
tool lifecycle events, and human-in-the-loop interactions.
This package provides the Python bindings and server stubs for the
protocol, enabling developers to build and interact with interoperable
agentic applications using strongly typed payloads. Manual pages: # FreshPorts has no man page information for this port.
