🤖 🚀 Agent Runtimes

Agent Runtimes is a unified library for deploying, managing, and interacting with AI agents across multiple protocols and frameworks. It provides both a Python server for hosting agents and React components for seamless integration into web and desktop applications.

What is Agent Runtimes?

Agent Runtimes solves the complexity of deploying AI agents by providing:

1. Protocol Abstraction: One agent, multiple protocols - deploy your agent once and access it through ACP, Vercel AI SDK, AG-UI, MCP-UI, or A2A without changing your code.

2. Framework Flexibility: Write agents using your preferred framework (Pydantic AI, LangChain, Jupyter AI) while maintaining a consistent API.

3. Cloud Runtime Management: Built-in integration with Datalayer Cloud Runtimes for launching and managing compute resources with Zustand-based state management.

4. UI Components: Pre-built React components (ChatBase, ChatSidebar, ChatFloating) that connect to agents and execute tools directly in the browser.

5. Tool Ecosystem: Seamless integration with MCP (Model Context Protocol) tools, custom tools, and built-in utilities for Jupyter notebooks and Lexical documents.

🌟 Features

Agent Node

• Central registration: Agent nodes register and heartbeat to Datalayer Runtimes APIs.
• Node configuration: Runtime mode (private, shared, sleep) and sharing metadata are tracked per node.
• Tunnel routing: Agent nodes maintain a tunnel with Datalayer Runtimes to route chat messages between central UI and nodes.
• Dedicated UI: Agent Node list/detail UX is available for node observability and operations.
• End-to-end sync: Local node state can be synchronized to central services for fleet visibility.

Multi-Protocol Support

• ACP (Agent Client Protocol): WebSocket-based standard protocol
• Vercel AI SDK: Compatible with Vercel's AI SDK for React/Next.js
• AG-UI: Lightweight web interface (Pydantic AI native)
• MCP-UI: Interactive UI resources protocol with React/Web Components
• A2A: Agent-to-agent communication

Multi-Agent Support

• Pydantic AI: Type-safe agents (fully implemented)

Examples

The examples demonstrate how to use the Agent Runtimes functionality in various scenarios and frameworks.

Install

make examples starts both the Python agent server and the Vite dev server, so you need both stacks installed once:

# 1. Node dependencies for the React examples + Vite dev server.
npm install

# 2. Python package (editable) for the local agent-runtimes server.
#    Use a virtualenv or conda env of your choice.
pip install -e .

Optional extras (declared in pyproject.toml):

pip install -e ".[examples]"   # extra agent framework deps used by examples
pip install -e ".[test]"       # pytest and test utilities
pip install -e ".[cli]"        # CLI dependencies
pip install -e ".[chat]"       # chat-related extras
pip install -e ".[docs]"       # docs build dependencies

Run

make examples

Agent Node development (UI + server)

For focused Agent Node development, run:

make agent-nodes

This target starts both:

• the local Python server on port 8765
• the Vite page for html/agent-node.html

Use this mode to iterate on Agent Node configuration flows and central registration behavior.

Expected central visibility semantics:

• show all nodes owned by the current user,
• show other users' nodes only when mode is shared.

Agent Node against local services (plane local)

To run Agent Node with local service URLs preconfigured, use:

make agent-nodes:proxy

This target applies the PLANE_LOCAL_*_URL mappings and exports both DATALAYER_* and VITE_* variables so Agent Node sync/tunnel and UI calls are wired to local services.

Prerequisites:

1. Start the local Plane stack (plane local).
2. Export DATALAYER_API_KEY for authenticated registration/tunnel calls.

Override any local service URL if needed:

PLANE_LOCAL_RUNTIMES_URL=http://localhost:19500 make agent-nodes:proxy

Docker build notes

Docker image build and release notes were moved to:

• docker/README.md

By default, make examples boots the local Vite dev server with every Datalayer service URLs set to local defaults for agent execution:

Variable	Default	Notes
VITE_BASE_URL	http://localhost:8765	Local agent-runtimes server (/api/v1/agents/*)
VITE_BASE_URL_NO_CODEMODE	http://localhost:8765	Local no-codemode agent endpoint
VITE_BASE_URL_CODEMODE	http://localhost:8766	Local codemode agent endpoint

This is the local-first workflow used during development. It avoids accidental remote calls for the core agent routes even if your shell exports DATALAYER_*_URL values.

Running with explicit production URLs

If you want to force production URLs for Datalayer services, use:

make examples:prod

This mode uses the DATALAYER_*_URL convention from datalayer-core (specifically datalayer_core/utils/urls.py) and propagates those values to the Vite HTML placeholders.

Override any URL on the command line:

make examples:prod DATALAYER_RUN_URL=https://prod2.datalayer.run

Running against a local plane local stack

If you are developing against a local Plane (plane local), use:

make examples:proxy

This points each DATALAYER_*_URL at the matching localhost port exposed by plane local (see services/plane/datalayer_plane/sbin/local.sh):

Variable	Default port
PLANE_LOCAL_IAM_URL	http://localhost:9700
PLANE_LOCAL_RUNTIMES_URL	http://localhost:9500
PLANE_LOCAL_SPACER_URL	http://localhost:9900
PLANE_LOCAL_LIBRARY_URL	http://localhost:9800
PLANE_LOCAL_MANAGER_URL	http://localhost:2100
PLANE_LOCAL_AI_AGENTS_URL	http://localhost:4400
PLANE_LOCAL_AI_INFERENCE_URL	http://localhost:4450
PLANE_LOCAL_MCP_SERVERS_URL	http://localhost:4111
PLANE_LOCAL_GROWTH_URL	http://localhost:6660
PLANE_LOCAL_SUCCESS_URL	http://localhost:3300
PLANE_LOCAL_STATUS_URL	http://localhost:4785
PLANE_LOCAL_SUPPORT_URL	http://localhost:2200

Override any port on the command line, e.g.:

PLANE_LOCAL_IAM_URL=http://localhost:9701 make examples:proxy

On the main page, you’ll find an example gallery (cards) that break things down into practical building blocks:

• UX patterns (aka GenUI) with protocols like A2UI and AG-UI
• Interactive or triggered workflows
• Agent Identity and Controls with guardrails, monitoring, tool approvals
• Programmatic tooling with Sandbox and Codemode for MCP and Skills
• Outputs and Notifications
• Real-time collaboration with users, subagents, and multi-agent teams
• Custom agents built from Agentspecs
• ...

Each of these concerns deserves more than a one-off solution—they need deep, composable, and pluggable implementations.
