🚀 Quick Start

Installation

# Install from PyPI
pip install mcp-compose

# Or install from source
git clone https://github.com/datalayer/mcp-compose.git
cd mcp-compose
pip install -e .

Using Docker (Recommended)

# Clone repository
git clone https://github.com/datalayer/mcp-compose.git
cd mcp-compose

# Start with docker-compose (includes Prometheus & Grafana)
docker-compose up -d

# Access the Web UI
open http://localhost:8000

Using CLI

# Start the server with Web UI
mcp-composer serve --config examples/mcp_compose.toml

# Access Web UI at http://localhost:8000
# Access API at http://localhost:8000/api/v1
# Access API docs at http://localhost:8000/docs

# Discover available MCP servers
mcp-composer discover

# Invoke a tool
mcp-composer invoke-tool calculator:add '{"a": 5, "b": 3}'

Using Python API

from mcp_compose import MCPServerComposer

# Create composer and start servers
composer = MCPServerComposer()
composer.load_config("config.toml")

# Start all servers
for server in composer.servers.values():
    await composer.start_server(server.name)

# List available tools
tools = await composer.list_tools()
print(f"Available tools: {[t.name for t in tools]}")

# Invoke a tool
result = await composer.invoke_tool("calculator:add", {"a": 5, "b": 3})
print(f"Result: {result}")

🎨 Web UI Features

The modern web interface provides:

• 📊 Dashboard - Overview of all servers, tools, and system metrics
• 🖥️ Server Management - Start, stop, restart servers with real-time status
• 🔧 Tool Browser - Search and invoke tools with interactive forms
• ⚙️ Configuration Editor - Edit and validate configuration files
• 📋 Log Viewer - Real-time log streaming with filtering

💡 What can you use MCP Compose for?

• Local AI development environments: Spin up multiple MCP servers (tools, data sources, agents) on your laptop with one command, inspect them live, and iterate faster.
• Agent tool ecosystems: Compose and expose tools from multiple MCP servers into a single, unified interface for AI agents — with clear conflict resolution strategies.
• Protocol bridging: Run legacy or CLI-based MCP servers over STDIO while exposing them to modern clients via SSE, without rewriting anything.
• Team & platform workflows: Standardize how MCP servers are started, monitored, and secured across teams using Docker, tokens, and a shared control plane.
• Observability & debugging: Track logs, metrics, and server health in real time through a Web UI or REST API — ideal for diagnosing tool behavior during agent runs.
• Production-ready orchestration: Deploy multiple MCP servers with authentication, monitoring, and lifecycle management — without building custom glue code.

✨ Key capabilities that enable these use cases:

• Unified multi-server start / stop / monitor
• REST API + modern React-based Web UI
• Tool discovery and intelligent composition
• Programmatic control via Python API
• Real-time metrics, logs, and monitoring

Made with ❤️ by Datalayer composer = MCPServerComposer( composed_server_name="unified-data-server", conflict_resolution=ConflictResolution.PREFIX )

Compose from current directory's pyproject.toml

unified_server = composer.compose_from_pyproject()

Get detailed composition information

summary = composer.get_composition_summary() print(f"Created server with {summary['total_tools']} tools")

#### Advanced Configuration

```python
from pathlib import Path
from mcp_compose import MCPServerComposer, ConflictResolution

# Specify custom pyproject.toml location
composer = MCPServerComposer(
    composed_server_name="my-server",
    conflict_resolution=ConflictResolution.SUFFIX
)

# Compose with filtering
unified_server = composer.compose_from_pyproject(
    pyproject_path=Path("custom/pyproject.toml"),
    include_servers=["jupyter-mcp-server", "earthdata-mcp-server"],
    exclude_servers=["deprecated-server"]
)

# Access composed tools and prompts
tools = composer.list_tools()
prompts = composer.list_prompts()
source_info = composer.get_source_info()

print(f"Tools: {', '.join(tools)}")
print(f"Sources: {', '.join(source_info.keys())}")

Discovery Only

from mcp_compose import MCPServerDiscovery

# Discover MCP servers without composing
discovery = MCPServerDiscovery()
servers = discovery.discover_from_pyproject("pyproject.toml")

for name, info in servers.items():
    print(f"{name}: {len(info.tools)} tools, {len(info.prompts)} prompts")

Configuration

Conflict Resolution Strategies

When multiple servers provide tools or prompts with the same name, you can choose how to resolve conflicts:

• PREFIX (default): Add server name as prefix (server1_tool_name)
• SUFFIX: Add server name as suffix (tool_name_server1)
• OVERRIDE: Last server wins (overwrites previous)
• IGNORE: Skip conflicting items
• ERROR: Raise an error on conflicts

Example Conflict Resolution

# If two servers both have a "search" tool:
# PREFIX: jupyter_mcp_server_search, earthdata_mcp_server_search
# SUFFIX: search_jupyter_mcp_server, search_earthdata_mcp_server
# OVERRIDE: Only the last server's "search" tool is kept

Real-World Examples

Data Science Workflow

Create a unified MCP server combining Jupyter notebook capabilities with Earth science data access:

# pyproject.toml
[project]
dependencies = [
    "jupyter-mcp-server>=1.0.0",
    "earthdata-mcp-server>=0.1.0",
    "weather-mcp-server>=2.0.0"
]

# Discover available tools
python -m mcp_compose discover

# Create unified server for data science workflow
python -m mcp_compose compose \
  --name "data-science-server" \
  --conflict-resolution prefix \
  --output unified_server.py

This creates a server with tools like:

• jupyter_create_notebook - Create analysis notebooks
• earthdata_search_datasets - Find Earth science data
• weather_get_forecast - Access weather data
• Combined prompts for data analysis workflows

Development Environment

Combine development tools and documentation servers:

from mcp_compose import MCPServerComposer, ConflictResolution

composer = MCPServerComposer(
    composed_server_name="dev-environment",
    conflict_resolution=ConflictResolution.PREFIX
)

# Compose development-focused servers
dev_server = composer.compose_from_pyproject(
    include_servers=[
        "code-review-mcp-server",
        "documentation-mcp-server", 
        "testing-mcp-server"
    ]
)

# Access all development tools in one place
print("Available tools:", composer.list_tools())

Custom Integration

from mcp_compose import MCPServerComposer
from my_custom_server import MyMCPServer

# Create composer
composer = MCPServerComposer()

# Compose discovered servers
unified_server = composer.compose_from_pyproject()

# Add your custom server manually if needed
composer.add_server("custom", MyMCPServer())

# Get final composition summary
summary = composer.get_composition_summary()
print(f"Final server has {summary['total_tools']} tools from {summary['source_servers']} sources")

Project Structure

When using MCP Compose, structure your project like this:

my-project/
├── pyproject.toml          # Define MCP server dependencies
├── src/
│   └── my_project/
│       ├── __init__.py
│       └── main.py         # Use composed server
├── composed_server.py      # Generated unified server (optional)
└── README.md

Sample pyproject.toml

[project]
name = "my-data-project"
dependencies = [
    "jupyter-mcp-server>=1.0.0",
    "earthdata-mcp-server>=0.1.0",
    "fastmcp>=1.2.0"
]

[project.optional-dependencies]
dev = [
    "pytest>=7.0.0",
    "mcp-compose>=1.0.0"
]

Error Handling

The library provides comprehensive error handling:

from mcp_compose import MCPServerComposer, MCPComposerError, MCPDiscoveryError

try:
    composer = MCPServerComposer()
    server = composer.compose_from_pyproject()
except MCPDiscoveryError as e:
    print(f"Discovery failed: {e}")
    print(f"Search paths: {e.search_paths}")
except MCPComposerError as e:
    print(f"Composition failed: {e}")
    print(f"Server count: {e.server_count}")

Troubleshooting

Common Issues

1. No MCP servers found: Ensure your dependencies include packages with "mcp" in the name
2. Import errors: Check that MCP server packages are properly installed
3. Naming conflicts: Use appropriate conflict resolution strategy
4. Missing tools: Verify that server packages export an app variable

Debug Mode

# Enable verbose logging
python -m mcp_compose discover --verbose

# Check specific package
python -c "
from mcp_compose import MCPServerDiscovery
discovery = MCPServerDiscovery()
result = discovery._analyze_mcp_server('your-package-name')
print(result)
"
