Hanzo Python SDK

The flagship Python SDK for the Open AI Cloud — models, agents, tools, memory, and MCP in one install.

This is the most complete Hanzo SDK — a uv workspace of 60+ composable packages covering the full AI surface: the typed cloud client, an agent framework, the Model Context Protocol server and tools, persistent memory + RAG, distributed compute, and a batteries-included CLI. If you build AI in Python, start here.

Install

pip install hanzo          # flagship: CLI + agents + MCP + client

Or install exactly what you need:

pip install hanzoai        # just the typed cloud API client
pip install "hanzo[all]"   # everything, including optional extras

Quickstart

from hanzoai import ApiClient, Configuration, AiOpenAICompatibleApi
from hanzoai import AiChatCompletionRequest, AiChatMessage

config = Configuration(host="https://api.hanzo.ai", access_token="sk-...")

with ApiClient(config) as client:
    ai = AiOpenAICompatibleApi(client)
    resp = ai.ai_create_chat_completion(
        AiChatCompletionRequest(
            model="zen-coder",
            messages=[AiChatMessage(role="user", content="Ship it.")],
        )
    )
    print(resp.choices[0].message.content)

Every route is https://api.hanzo.ai/v1/<service>/*. Models come from the Zen family (our own models) plus any provider you connect — one typed client, no proxy in the middle.

Packages

The workspace splits cleanly by concern. The headline packages:

Package	Purpose
hanzoai	Typed cloud API client (generated from the Hanzo OpenAPI surface).
hanzo	The hanzo CLI + runtime that ties everything together.
hanzo-mcp	Model Context Protocol server — discovers tools via entry points.
hanzo-agents / hanzo-agent	Agent framework — build and orchestrate agents and swarms.
hanzo-network	Distributed AI compute and node orchestration.
hanzo-memory	Persistent memory + RAG (SQLite, optional vector backends).
hanzo-tools-*	60+ single-concern tool packages (shell, browser, fs, code, vector, iam, …), each exposing a TOOLS list.

CLI

pip install hanzo gives you the hanzo command:

hanzo chat            # chat with the Zen models
hanzo node            # start / manage a local compute node
hanzo mcp             # run the MCP server for your editor or agent
hanzo agent           # build and run agents
hanzo run             # run a workflow
hanzo cloud           # manage cloud resources
hanzo search          # AI-powered search

Run hanzo --help for the full command tree.

Model Context Protocol (hanzo-mcp)

hanzo-mcp hosts the MCP server and discovers tools through [project.entry-points."hanzo.tools"], so any installed hanzo-tools-* package lights up automatically.

from hanzo_mcp import create_mcp_server

server = create_mcp_server()
server.register_tool(my_tool)
server.start()

Agents (hanzo-agents)

from hanzo_agents import Agent, Swarm

agent = Agent(
    name="researcher",
    model="zen-coder",
    instructions="You are a research assistant.",
)

swarm = Swarm([agent])
result = await swarm.run("Research quantum computing.")

Network (hanzo-network)

from hanzo_network import LocalComputeNode, DistributedNetwork

node = LocalComputeNode(node_id="node-001")
network = DistributedNetwork()
network.register_node(node)

Memory (hanzo-memory)

Persistent memory and RAG backed by SQLite, with optional vector search (sqlite-vec, lancedb, kuzu). Global state lives in ~/.hanzo/; per-project state in .hanzo/.

from hanzo_memory import MemoryService

memory = MemoryService()
await memory.store("key", "value")
result = await memory.retrieve("key")

Development

This is a uv workspace.

git clone https://github.com/hanzoai/python-sdk.git
cd python-sdk
uv sync --all-packages       # install the whole workspace

uv run pytest tests/ -v      # run tests
make lint                    # ruff lint
make format                  # ruff format
make type-check              # mypy / pyright

Per-package work:

uv run pytest pkg/hanzo-mcp -v
cd pkg/hanzo && uv build
