unifai-sdk 0.2.2

Unifai Python SDK

unifai-sdk-py

unifai-sdk-py is the Python SDK for Unifai, an AI native platform for dynamic tools and agent to agent communication.

Installation

pip install unifai-sdk

Getting your Unifai API key

You can get your API key for free from Unifai.

There are two types of API keys:

• Agent API key: for using toolkits in your own agents.

• Toolkit API key: for creating toolkits that can be used by other agents.

Using tools

To use tools in your agents, you need an agent API key. You can get an agent API key for free at Unifai.

import unifai

tools = unifai.Tools(api_key='xxx')

Then you can pass the tools to any OpenAI compatible API. Popular options include:

• OpenAI's native API: For using OpenAI models directly
• Litellm: A library that provides a unified OpenAI compatible API to most LLM providers
• OpenRouter: A service that gives you access to most LLMs through a single OpenAI compatible API

The tools will work with any API that follows the OpenAI function calling format. This gives you the flexibility to choose the best LLM for your needs while keeping your tools working consistently.

response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"content": "Can you tell me what is trending on Google today?", "role": "user"}],
    tools=tools.get_tools(),
)

If the response contains tool calls, you can pass them to the tools.call_tools method to get the results. The output will be a list of messages containing the results of the tool calls that can be concatenated to the original messages and passed to the LLM again.

results = await tools.call_tools(response.choices[0].message.tool_calls)
messages.extend(results)
# messages can be passed to the LLM again now

Passing the tool calls results back to the LLM might get you more function calls, and you can keep calling the tools until you get a response that doesn't contain any tool calls. For example:

messages = [{"content": "Can you tell me what is trending on Google today?", "role": "user"}]
while True:
    response = client.chat.completions.create(
        model="gpt-4o",
        messages=messages,
        tools=tools.get_tools(),
    )
    messages.append(response.choices[0].message)
    results = await tools.call_tools(response.choices[0].message.tool_calls)
    if len(results) == 0:
        break
    messages.extend(results)

Using tools in MCP clients

We provide a MCP server to access tools in any MCP clients such as Claude Desktop.

The easiest way to run the server is using uv, see Instaling uv if you haven't installed it yet.

Then in your Claude Desktop config:

{
  "mcpServers": {
    "unifai-tools": {
      "command": "uvx",
      "args": [
        "--from",
        "unifai-sdk",
        "unifai-tools-mcp"
      ],
      "env": {
        "UNIFAI_AGENT_API_KEY": ""
      }
    }
  }
}

Now your Claude Desktop will be able to access all the tools in Unifai automatically.

Creating tools

Anyone can create dynamic tools in Unifai by creating a toolkit.

A toolkit is a collection of tools that are connected to the Unifai infrastructure, and can be searched and used by agents dynamically.

Initialize a toolkit client with your toolkit API key. You can get a toolkit API key for free at Unifai.

import unifai

toolkit = unifai.Toolkit(api_key='xxx')

Update the toolkit name and/or description if you need:

await toolkit.update_toolkit(name="Echo Slam", description="What's in, what's out.")

or running it as a synchronous method with asyncio.run():

asyncio.run(toolkit.update_toolkit(name="Echo Slam", description="What's in, what's out."))

Register action handlers:

@toolkit.action(
    action="echo",
    action_description='Echo the message',
    payload_description={"content": {"type": "string"}},
)
def echo(ctx: unifai.ActionContext, payload={}): # can be an async function too
    return ctx.Result(f'You are agent <{ctx.agent_id}>, you said "{payload.get("content")}".')

Note that payload_description can be any string or a dict that contains enough information for agents to understand the payload format. It doesn't have to be in certain format, as long as agents can understand it as nautural language and generate correct payload. Think of it as the comments and docs for your API, agents read it and decide what parameters to use.

Start the toolkit:

await toolkit.run()

or running it as a synchronous method with asyncio.run():

asyncio.run(toolkit.run())
