Ergonomic LLM Agents

Agentia: Ergonomic LLM Agents

Ergonomic LLM Agents with MCP and Skills support.

Getting Started

Run agents with tools, MCP, and Skills

from agentia import Agent, MCP
from typing import Annotated

# Define a tool as a python function
def get_weather(location: Annotated[str, "The city name"]):
    """Get the current weather in a given location"""
    return { "temperature": 72 }

# Declare a MCP server:
calc = MCP(name="calculator", command="uvx", args=["mcp-server-calculator"])

# Create an agent
# This will load the function tool, the calculator MCP, and all skills under $CWD/.skills
agent = Agent(model="openai/gpt-5-nano", tools=[get_weather, calc], skills=True)

# Run the agent with the mcp
response = await agent.run("Calculate 234 ** 3")

print(response.text)

# Output: The result of 234 raised to the power of 3 is 12,812,904.

The Magic Decorator

Create agent-powered magic functions.

Support both plain types and pydantic models as input and output.

from agentia import magic
from pydantic import BaseModel

class Forcast(BaseModel):
    location: str
    temperature_celsius: int

@magic
async def get_weather(weather_forcast: str) -> Forcast:
    """Create weather forcase object based on the input string"""
    ...

forcast = await get_weather("The current temperature in Boston is 72°F")

print(forcast.location) # Output: Boston
print(forcast.temperature_celsius) # Output: 22
