Python SDK for external integration with the unified-ui platform — tracing, streaming, agents, and more.

unified-ui SDK

Python SDK for external integration with the unified-ui platform — tracing, streaming, agents, and more!

What is unified-ui?

unified-ui transforms the complexity of managing multiple AI systems into a single, cohesive experience. Organizations deploy agents across diverse platforms — Microsoft Foundry, n8n, LangGraph, Copilot, and custom solutions — resulting in fragmented user experiences, inconsistent monitoring, and operational silos.

unified-ui eliminates these challenges by providing one interface where every agent converges.

What is this SDK?

The unified-ui SDK is a complementary Python package that provides capabilities for external integration with the unified-ui platform:

Module	Description
🔍 Tracing	Standardized tracing objects; LangChain & LangGraph trace sniffing and forwarding
📡 Streaming	Standardized streaming response protocol for unified-ui
🤖 Agents	ReACT Agent class with an agent engine built on LangChain / LangGraph
🔧 Tools	Reusable tool clients (Microsoft 365 Graph API) for building AI agents
🧱 Core	Shared interfaces, base classes, and utility functions

Installation

pip install unifiedui-sdk

Or with uv:

uv add unifiedui-sdk

Quick Start

Tracing — Capture Traces from LangChain / LangGraph

from unifiedui_sdk.tracing import UnifiedUILanggraphTracer

tracer = UnifiedUILanggraphTracer()

# Attach to any LangChain/LangGraph execution
result = graph.invoke(
    {"messages": [("human", "Hello")]},
    config={"callbacks": [tracer]},
)

# Get the trace as a dict (camelCase JSON for the agent-service API)
trace_dict = tracer.get_trace_dict()

Streaming — Build SSE Responses

from unifiedui_sdk.streaming import StreamWriter, StreamMessageType

writer = StreamWriter()

# Build stream messages for the unified-ui SSE protocol
yield writer.stream_start()
yield writer.text_stream("Hello ")
yield writer.text_stream("world!")
yield writer.tool_call_start("tc_1", "search", {"query": "test"})
yield writer.tool_call_end("tc_1", "search", "success", tool_result="Found 3 results")
yield writer.stream_end()

Agents — Single-Agent with Tools

from langchain_openai import ChatOpenAI
from langchain_core.tools import tool

from unifiedui_sdk.agents import ReActAgentConfig, ReActAgentEngine
from unifiedui_sdk.tracing import ReActAgentTracer


@tool
def calculator(expression: str) -> str:
    """Evaluate a math expression."""
    return str(eval(expression))


llm = ChatOpenAI(model="gpt-4o-mini", temperature=0.1)
config = ReActAgentConfig(system_prompt="You are a helpful assistant.")
tracer = ReActAgentTracer()

engine = ReActAgentEngine(
    config=config, llm=llm, tools=[calculator], tracer=tracer
)

# Stream agent execution
async for msg in engine.invoke_stream("What is 42 * 17?"):
    if msg.type == "TEXT_STREAM":
        print(msg.content, end="", flush=True)
    elif msg.type == "TOOL_CALL_START":
        print(f"\nTool: {msg.config['tool_name']}")
    elif msg.type == "TOOL_CALL_END":
        print(f"Result: {msg.config['tool_result']}")

Agents — Multi-Agent Orchestration

from unifiedui_sdk.agents import ReActAgentConfig, ReActAgentEngine
from unifiedui_sdk.agents.config import MultiAgentConfig
from unifiedui_sdk.tracing import ReActAgentTracer

config = ReActAgentConfig(
    system_prompt="You are a research assistant.",
    multi_agent_enabled=True,
    multi_agent=MultiAgentConfig(
        max_sub_agents=5,
        max_parallel_per_step=3,
    ),
)

tracer = ReActAgentTracer()
engine = ReActAgentEngine(config=config, llm=llm, tools=[...], tracer=tracer)

async for msg in engine.invoke_stream("Compare weather in Berlin, Munich, Hamburg"):
    if msg.type == "PLAN_COMPLETE":
        print("Plan:", msg.config["plan"]["goal"])
    elif msg.type == "SUB_AGENT_STREAM":
        print(msg.content, end="")
    elif msg.type == "SYNTHESIS_STREAM":
        print(msg.content, end="")

# Get the full trace
trace = tracer.get_trace()

Agents — Tool Loading (OpenAPI + MCP)

from unifiedui_sdk.agents.config import ToolConfig, ToolType, MCPTransport
from unifiedui_sdk.agents.tools.loader import load_tools

tool_configs = [
    ToolConfig(
        name="PetStore",
        type=ToolType.OPENAPI_DEFINITION,
        config={
            "spec_url": "https://petstore3.swagger.io/api/v3/openapi.json",
            "base_url": "https://petstore3.swagger.io/api/v3",
        },
    ),
    ToolConfig(
        name="MCP Weather",
        type=ToolType.MCP_SERVER,
        config={
            "url": "http://localhost:8080/sse",
            "transport": MCPTransport.SSE,
        },
    ),
]

tools = await load_tools(tool_configs)
engine = ReActAgentEngine(config=config, llm=llm, tools=tools)

Tools — Microsoft 365 Clients

pip install unifiedui-sdk[m365]

from unifiedui_sdk.tools.m365 import (
    OutlookAPIClient,
    OutlookAuthProvider,
    OutlookCapability,
    SendMessage,
)

auth = OutlookAuthProvider(
    tenant_id="your-tenant-id",
    client_id="your-client-id",
    client_secret="your-client-secret",
)

client = OutlookAPIClient(
    auth_provider=auth,
    capabilities=[OutlookCapability.MAIL_READ, OutlookCapability.MAIL_SEND],
)

# Send email
client.messages.send(
    user_id="me",
    message=SendMessage(
        to=["[e-mail]"],
        subject="Hello",
        body="<p>Message from unified-ui agent</p>",
    ),
)

Branching Strategy

This project follows a Simplified Flow branching model with automatic versioning — optimized for SDK releases with semantic versioning.

gitGraph
    commit id: "init"
    branch develop
    checkout develop
    commit id: "setup"

    branch feat/tracing
    checkout feat/tracing
    commit id: "add tracing"
    commit id: "tracing tests"
    checkout develop
    merge feat/tracing id: "merge tracing"

    branch fix/memory-leak
    checkout fix/memory-leak
    commit id: "fix leak"
    checkout develop
    merge fix/memory-leak id: "merge fix"

    branch feat/streaming
    checkout feat/streaming
    commit id: "add streaming"
    checkout develop
    merge feat/streaming id: "merge streaming"

    merge fix/validation id: "merge validation"

    checkout main
    merge develop id: "v0.1.1" tag: "v0.1.1 (auto)"

    checkout main
    branch hotfix/security
    checkout hotfix/security
    commit id: "critical fix"
    checkout main
    merge hotfix/security id: "v0.1.2" tag: "v0.1.2 (auto)"
    checkout develop

    checkout develop
    commit id: "bump to 0.2.0"
    checkout main
    merge develop id: "v0.2.0" tag: "v0.2.0 (auto)"

Auto-Versioning

Every merge to main triggers automatic versioning:

┌─────────────────────────────────────────────────────────────────────────┐
│                                                                         │
│  pyproject.toml          PyPI Current        Next Version              │
│  (version floor)                                                        │
│  ────────────────────────────────────────────────────────────────────── │
│  0.1.0                   (not published)  →  0.1.0                     │
│  0.1.0                   0.1.0            →  0.1.1  (patch++)          │
│  0.1.0                   0.1.5            →  0.1.6  (patch++)          │
│  0.2.0                   0.1.6            →  0.2.0  (minor bump!)      │
│  1.0.0                   0.9.9            →  1.0.0  (major bump!)      │
│                                                                         │
└─────────────────────────────────────────────────────────────────────────┘

To release a new minor/major version: Update version in pyproject.toml on develop, then merge to main.

Branch Types

Branch	Purpose	Branches from	Merges into
main	Production releases — every merge triggers PyPI deployment	—	—
develop	Integration branch for features and fixes	main	main
feat/<name>	New features or enhancements	develop	develop
fix/<name>	Bug fixes (non-critical)	develop	develop
hotfix/<name>	Critical production fixes	main	main + develop
docs/<name>	Documentation-only changes	develop	develop
refactor/<name>	Code restructuring without behavior changes	develop	develop

Workflow

1. Feature/Fix development — Create a feat/ or fix/ branch from develop. Open a PR back into develop.
2. Release — When ready, open a PR from develop to main. On merge, CD automatically:
   • Calculates next version (floor + PyPI patch increment)
   • Creates git tag
   • Publishes to PyPI
   • Generates changelog and GitHub Release
3. Hotfixes — For critical bugs, create a hotfix/ branch from main, fix, and PR to main. Then backport to develop.

Rules

• Never commit directly to main or develop — always use PRs
• All PRs require passing CI (tests, lint, type check, coverage ≥ 80%)
• Squash merge feature/fix branches into develop for a clean history
• Tag format: v<major>.<minor>.<patch> (auto-generated)
• Branch naming: <type>/<short-description> (e.g. feat/langchain-tracing, fix/memory-leak)
