Implements an MCP server in Python that exposes resources, tools, and prompts for LLM interactions, utilizing Python's capabilities for building the state machine orchestration system
MCP Agent Orchestration System
A Python implementation of a state-based agent orchestration system using the Model Context Protocol (MCP).
What is MCP?
The Model Context Protocol (MCP) allows applications to provide context for LLMs in a standardized way, separating the concerns of providing context from the actual LLM interaction. With MCP, you can build servers that expose:
Resources: Data sources that provide information to LLMs
Tools: Functions that allow LLMs to perform actions
Prompts: Reusable templates for LLM interactions
Installation
Prerequisites
Python 3.10 or higher
MCP Python SDK 1.2.0 or higher
Setting Up Your Environment
Using uv (recommended)
# Install uv
curl -LsSf https://astral.sh/uv/install.sh | sh
# Create a new directory for our project
uv init mcp-agents-orchestra
cd mcp-agents-orchestra
# Create virtual environment and activate it
uv venv
source .venv/bin/activate # On Unix/macOS
.venv\Scripts\activate # On Windows
# Install dependencies
uv add "mcp[cli]" httpx
Using pip
# Create a new directory for our project
mkdir mcp-agents-orchestra
cd mcp-agents-orchestra
# Create a virtual environment
python -m venv venv
source venv/bin/activate # On Unix/macOS
venv\Scripts\activate # On Windows
# Install dependencies
pip install "mcp[cli]" httpx
Clone or Download Project Files
Place the project files in your directory:
orchestrator.py- The main MCP server implementing the state machineorchestrator_client.py- Client demonstrating the orchestration flowrequirements.txt- Dependencies for the project.gitignore- Git ignore file
Project Structure
orchestrator.py- The main MCP server implementing the state machineorchestrator_client.py- Client demonstrating the orchestration flowrequirements.txt- Dependencies for the project
Running the Orchestration System
Start the orchestration server directly for testing:
python orchestrator.py
In a separate terminal, run the client to see the orchestration in action:
python orchestrator_client.py
Integrating with Claude for Desktop
1. Install Claude for Desktop
Make sure you have Claude for Desktop installed. You can download the latest version from Anthropic's website.
2. Configure Claude for Desktop
Open your Claude for Desktop configuration file:
macOS/Linux:
# Create or edit the configuration file code ~/Library/Application\ Support/Claude/claude_desktop_config.jsonWindows:
# Path may vary depending on your Windows version code %APPDATA%\Claude\claude_desktop_config.jsonAdd the orchestrator server configuration:
{ "mcpServers": { "agent-orchestrator": { "command": "python", "args": [ "/ABSOLUTE/PATH/TO/YOUR/PROJECT/orchestrator.py" ] } } }Replace the path with the absolute path to your orchestrator.py file.
Save the configuration file and restart Claude for Desktop.
3. Using the Orchestrator in Claude
Once configured, you can:
Open Claude for Desktop
Click on the MCP server icon in the sidebar
Select "agent-orchestrator" from the list of available servers
Start interacting with the orchestration system
Claude will be able to:
Transition between different agent states
Store and retrieve information from the knowledge base
Maintain conversation context across state transitions
Access state-specific prompts
Agent States
The orchestration system implements a state machine with the following states:
IDLE: Waiting for instructions
PLANNING: Creating a structured plan for a task
RESEARCHING: Gathering information needed for a task
EXECUTING: Carrying out planned actions
REVIEWING: Evaluating results and determining next steps
ERROR: Handling errors or unexpected situations
Customizing the System
Adding New States
Add the state to the
AgentStateenum inorchestrator.pyCreate a prompt function for the new state
Update the transition logic in
_get_available_transitions()Add handlers for the new state in resource access functions
Creating Custom Tools
Add new tools by creating functions decorated with @mcp.tool():
@mcp.tool()
def my_custom_tool(arg1: str, arg2: int, ctx: Context) -> str:
"""Description of what this tool does
Args:
arg1: Description of arg1
arg2: Description of arg2
"""
# Implementation here
return "Result"
Development and Testing
Using the MCP CLI
The MCP CLI provides tools for development and testing:
# Install MCP CLI if you haven't already
pip install "mcp[cli]"
# Test your server with the MCP Inspector
mcp dev orchestrator.py
# Install in Claude Desktop
mcp install orchestrator.py
Manual Testing with Python
from mcp import ClientSession, StdioServerParameters
from mcp.client.stdio import stdio_client
async with stdio_client(StdioServerParameters(command="python", args=["orchestrator.py"])) as (read, write):
async with ClientSession(read, write) as session:
await session.initialize()
# Test state transitions
await session.call_tool("transition_state", arguments={"new_state": "PLANNING"})

This server cannot be installed
local-only server
The server can only run on the client's local machine because it depends on local resources.
A state-based agent orchestration system that allows transitions between different states (IDLE, PLANNING, RESEARCHING, EXECUTING, REVIEWING, ERROR) while maintaining conversation context and providing state-specific prompts.
