MCP-Native Agentic Framework for General-Purpose Task Automation

Fluxibly

MCP-Native Agentic Framework for General-Purpose Task Automation

Fluxibly is a modular, extensible agentic framework with native support for the Model Context Protocol (MCP). It enables developers to create sophisticated AI agents that can interact with external tools and services through MCP servers.

Features

• MCP-Native Architecture: First-class support for Model Context Protocol servers
• Flexible Workflow Engine: Execute single tasks or batch operations with ease
• Stateful Conversations: Maintain context across multiple interactions
• Profile-Based Configuration: Easy setup with YAML-based configuration profiles
• Async-First Design: Fully asynchronous API for high performance

Installation

Install Fluxibly using pip:

pip install fluxibly

Or using uv (recommended):

uv add fluxibly

Quick Start

Simple One-Shot Execution

import asyncio
from fluxibly import run_workflow

async def main():
    response = await run_workflow(
        "What is the capital of France?",
        profile="default"
    )
    print(response)

asyncio.run(main())

Using the Workflow Engine

import asyncio
from fluxibly import WorkflowEngine, WorkflowConfig

async def main():
    # Configure the workflow
    config = WorkflowConfig(
        name="my_workflow",
        agent_type="orchestrator",
        profile="default",
        stateful=False
    )

    # Create and initialize engine
    engine = WorkflowEngine(config=config)
    try:
        await engine.initialize()
        response = await engine.execute("Your task here")
        print(response)
    finally:
        await engine.shutdown()

asyncio.run(main())

Batch Processing

import asyncio
from fluxibly import run_batch_workflow

async def main():
    tasks = [
        "Explain async/await in Python",
        "What are Python decorators?",
        "How does the GIL work?"
    ]

    responses = await run_batch_workflow(
        tasks,
        profile="development_assistant"
    )

    for task, response in zip(tasks, responses):
        print(f"Q: {task}")
        print(f"A: {response}\n")

asyncio.run(main())

Configuration

Fluxibly uses YAML-based configuration profiles. You can use built-in profiles or create custom ones.

Using Custom Profile Files

You can load profiles from custom file paths:

# Load by absolute path
engine = WorkflowEngine.from_profile("/path/to/my_profile.yaml")

# Load by relative path
engine = WorkflowEngine.from_profile("../custom_profiles/special.yaml")

# Also works with convenience functions
response = await run_workflow(
    "Your task",
    profile="/path/to/my_profile.yaml"
)

Configuring Custom MCP Server Paths

You can specify custom paths for MCP server configurations:

from fluxibly import WorkflowConfig, WorkflowEngine

# Option 1: Absolute path to MCP config
config = WorkflowConfig(
    name="my_workflow",
    profile="default",
    mcp_config_path="/path/to/my_mcp_servers.yaml"
)

engine = WorkflowEngine(config=config)
await engine.initialize()

# Option 2: Relative path (relative to config_dir)
config = WorkflowConfig(
    name="my_workflow",
    profile="default",
    mcp_config_path="custom/mcp_servers.yaml",  # Relative to config_dir
    config_dir="/path/to/configs"
)

# Option 3: With WorkflowSession
from fluxibly import WorkflowSession

config = WorkflowConfig(
    name="custom_workflow",
    profile="default",
    mcp_config_path="/absolute/path/to/mcp_servers.yaml"
)

async with WorkflowSession(config=config) as session:
    response = await session.execute("Your task")

Profile Format

Here's an example profile structure:

name: default
description: Default configuration profile

llm:
  provider: anthropic
  model: claude-sonnet-4-5-20250929
  temperature: 0.7
  max_tokens: 4096

mcp:
  enabled: true
  servers_config: config/mcp_servers.yaml

MCP Server Integration

Fluxibly provides seamless integration with MCP servers. Configure your MCP servers in config/mcp_servers.yaml:

servers:
  filesystem:
    command: npx
    args:
      - -y
      - "@modelcontextprotocol/server-filesystem"
      - "/path/to/allowed/directory"
    env:
      NODE_OPTIONS: "--max-old-space-size=4096"

Then use the MCP client manager in your code:

from fluxibly import MCPClientManager

async def main():
    manager = MCPClientManager()
    await manager.initialize()

    # MCP tools are now available to your agents
    # ...

    await manager.cleanup()

Advanced Features

Stateful Conversations

config = WorkflowConfig(
    name="stateful_workflow",
    agent_type="agent",
    profile="default",
    stateful=True  # Enable state persistence
)

engine = WorkflowEngine(config=config)
await engine.initialize()

# First interaction
response1 = await engine.execute("My name is Alice")

# Context is preserved
response2 = await engine.execute("What's my name?")
# Response will remember "Alice"
