## Overview

The MCP Composer is a [FastMCP](https://github.com/jlowin/fastmcp) based Composer that manages multiple MCP servers and tools.
Servers and tools can be registered at runtime using structured JSON configurations.
The MCP Composer serves as an orchestrator for tool execution and forwards tool requests to the correct upstream MCP server or interface.

The MCP Composer supports multiple tool types, such as OpenAPI (REST), GraphQL, CLI-based tools, client SDKs, and nested MCP servers.

## Purpose

The goal of the MCP Composer is to handle dynamic tool registration, authentication, invocation dispatching, and health monitoring.
It abstracts underlying protocol, authentication and routing complexities,
and allows tools to be called through a single, unified interface. The MCP Composer exposes a set of MCP-compliant functions that allow listing tools, invoking them, updating credentials, and removing them.

The goal is to provide a single unified MCP Composer that:

- Discovers and registers new MCP tools on startup or via API.
- Mounts and unmounts member servers dynamically.
- Exposes all tools across registered servers.

## Installation

Update the pyproject.toml if you need to install both `mcp_composer` and `mcp_composer_app`

```
[tool.setuptools.packages.find]
where = ["src"]
include = ["mcp_composer", "mcp_composer_app"]
```

If we only want to install `mcp_composer`

```
[tool.setuptools.packages.find]
where = ["src"]
include = ["mcp_composer"]
```

For multiple installation methods, please refer to the [**Installation Guide**](https://ibm.github.io/mcp-composer/guide/installation.html)

### Prerequisites

- Python 3.10+
- [uv](https://docs.astral.sh/uv/) (Recommended for environment management)

### Setup

1. Clone the repository

   ```bash
   git clone https://github.com/IBM/mcp-composer.git
   cd mcp-composer
   ```

2. Create virtual Environment:

   ```bash
   uv venv 
   ```

3. Activate the virtual environment.

   ```bash
   source .venv/bin/activate
   ```

4. **Environment Configuration (Required)**

   The MCP Composer requires environment variables to be set:

   **Setup**

   ```bash
   cp env.example .env
   ```

   Edit the `.env` file and set the required environment variables:
   - `SERVER_CONFIG_FILE_PATH`: Path to the server configuration file (default: `member_servers.json`)

   **Note**: If you don't set up the `.env` file, you'll get a `KeyError: 'SERVER_CONFIG_FILE_PATH'` error when trying to import the module.

5. **Database Configuration (Optional)**

   The MCP Composer supports multiple database backends for storing server configurations, tools, prompts, and resources:

   **Default Behavior**: If no database configuration is provided, MCP Composer runs without persistent storage (no database).

   **Environment Variable Configuration (Recommended)**:

   You can configure the database using environment variables, which take priority over programmatic configuration:

   ```bash
   # For Cloudant database
   export MCP_DATABASE_TYPE="cloudant"
   export MCP_DATABASE_API_KEY="your_cloudant_api_key"
   export MCP_DATABASE_SERVICE_URL="https://your-cloudant-instance.cloudantnosqldb.appdomain.cloud"
   export MCP_DATABASE_DB_NAME="mcp_servers"  # Optional, defaults to "mcp_servers"
   
   # For local file storage
   export MCP_DATABASE_TYPE="local_file"
   export MCP_DATABASE_FILE_PATH="/path/to/your/servers.json"  # Optional
   
   # Enable local file storage when no other database config is provided
   export MCP_USE_LOCAL_FILE_STORAGE="true"
   ```

   [**Environment Variables**](https://ibm.github.io/mcp-composer/guide/configuration.html#environment-variables):
   - `MCP_DATABASE_TYPE`: Database type (`"cloudant"` or `"local_file"`)
   - `MCP_DATABASE_API_KEY`: API key for Cloudant (required for cloudant type)
   - `MCP_DATABASE_SERVICE_URL`: Service URL for Cloudant (required for cloudant type)
   - `MCP_DATABASE_DB_NAME`: Database name (optional, defaults to `"mcp_servers"`)
   - `MCP_DATABASE_FILE_PATH`: File path for local storage (optional for local_file type)
   - `MCP_USE_LOCAL_FILE_STORAGE`: Set to `"true"` to enable local file storage when no other config is provided

   **Programmatic Database Configuration**:

   You can also provide a `database_config` dictionary when initializing MCPComposer:

   ```python
   from mcp_composer import MCPComposer
   
   # Cloudant configuration
   database_config = {
       "type": "cloudant",
       "api_key": "your_cloudant_api_key",
       "service_url": "https://your-cloudant-instance.cloudantnosqldb.appdomain.cloud",
       "db_name": "mcp_servers"  # Optional, defaults to "mcp_servers"
   }
   
   composer = MCPComposer(
       name="my-composer",
       database_config=database_config
   )
   ```

   **Local File Storage Configuration**:

   ```python
   from mcp_composer import MCPComposer
   
   # Local file storage configuration
   database_config = {
       "type": "local_file",
       "file_path": "/path/to/your/servers.json"  # Optional
   }
   
   composer = MCPComposer(
       name="my-composer",
       database_config=database_config
   )
   ```

   **Required Cloudant Parameters**:
   - `type`: Must be set to `"cloudant"`
   - `api_key`: Your IBM Cloudant API key
   - `service_url`: Your Cloudant service URL (must start with `http://` or `https://`)

   **Optional Cloudant Parameters**:
   - `db_name`: Database name (defaults to `"mcp_servers"`)

   **Custom Database Interface**:

   You can also provide a custom database implementation by passing a `DatabaseInterface` instance:

   ```python
   from mcp_composer.store.database import DatabaseInterface
   
   class MyCustomDatabase(DatabaseInterface):
       # Implement required methods
       pass
   
   custom_db = MyCustomDatabase()
   composer = MCPComposer(
       name="my-composer",
       database_config=custom_db
   )
   ```

   **Configuration Priority**:
   1. Environment variables (highest priority)
   2. Programmatic configuration
   3. No database (default behavior)

   **Error Handling**: If database configuration is provided but missing required keys or has invalid values, the composer will log warnings and fall back to no database configuration.

6. Synchronize the environment.

   **First time setup**: Run this to create the initial `uv.lock` file:

   ```bash
   uv sync
   ```

   **Subsequent runs**: Use the frozen lock file for consistency:

   ```bash
   uv sync --frozen        # Strict install (uses lock file exactly) - recommended as ensuring consistency across different environments
   ```

   **Update dependencies**: If you need to update dependencies:

   ```bash
   rm uv.lock && uv sync # Refresh child dependencies, commit uv.lock
   ```

7. Add a new dependency; automatically creates a virtual environment if necessary

   ```bash
   uv add <my-package>   
   ```

8. Leverage the project's virtual environment:

   ```
   uv run <command&args> 
   ```

9. Test if MCP Composer is installed successfully or not

   ```bash
   uv run python -c "import mcp_composer; print(mcp_composer.__version__)"
   ```

### Add MCP Composer as local dependency

1. Update the `pyproject.toml` with the following:

```toml
[tool.hatch.metadata]
allow-direct-references = true
```

Then you can run the command:

```bash
uv add <path to mcp-composer folder>
```

Then, the pyproject.toml file is updated with the below lines:

```toml
[tool.uv.sources]
mcp-composer = { path = "mcp-composer" }
```

Add mcp-composer to the dependencies section, example of the final pyproject.toml file:

```toml  
[project]
name = "py_project"

[tool.hatch.metadata]
allow-direct-references = true

dependencies = [
    "mcp-composer",
    ... ...
]

[tool.uv.sources]
mcp-composer= { path = "mcp-composer" }
```

To ensure the package is properly installed and importable in the consumer project, the following command must be run manually:

```bash
uv pip install -e ../mcp-composer
```

### Use as Tool

- Handles multiple authentication strategies.
- Automatically forwards each request to the correct upstream server or tool.
- List tools and metadata by name or server.
- **Database Support**: Configurable database backends including IBM Cloudant and local file storage for persistent server configurations, tools, prompts, and resources.
- **Environment Variable Configuration**: Database configuration through environment variables with validation and fallback support.
- **Database Configuration Validation**: Strict validation of database configuration with fail-fast behavior to prevent startup with invalid database settings.

### MCP Composer Servers

#### Add MCP Server from local python file in stdio

To add an MCP server from a local python file, use the builder with a configuration containing the python file path:

**Example:**

```
[
  {
    "id": "mcp-local-news",
    "type": "stdio",
    "command": "uv",
    "args": [
      "--directory",
      "/<absolute path of the directory>",
      "run",
      "<name of the python file>.py"
    ],
    "_id": "mcp-local-news"
  }
]
```

Run

```bash
uv run test/test_composer.py
```

test_composer.py can run on either `stdio` or `http` type.
This will create a FastMCP server instance using the python file and its dependencies and also mount it on mcp-composer.

#### Add MCP Server from OpenAPI Specification

To add an MCP server from an OpenAPI spec, use the builder with a configuration containing the OpenAPI details:

**Example:**

```python
from mcp_composer.member_servers.builder import MCPServerBuilder

config = {
    "id": "my-openapi-server",
    "type": "openapi",
    "open_api": {
        "endpoint": "https://api.example.com",
        "spec_url": "https://api.example.com/openapi.json",
        # Optional: "custom_routes": "path/to/custom_routes.json"
    },
    "auth_strategy": "bearer",
    "auth": {
        "token": "your-token"
    }
}
builder = MCPServerBuilder(config)
mcp_server = await builder.build()
```

This will create a FastMCP server instance using the OpenAPI specification and authentication details provided.

---

#### Add MCP Server from GraphQL Schema

To add an MCP server from a GraphQL schema, use the builder with a configuration containing the GraphQL endpoint:

**Example:**

```python
from mcp_composer.member_servers.builder import MCPServerBuilder

config = {
    "id": "my-graphql-server",
    "type": "graphql",
    "endpoint": "https://graphql.example.com/graphql",
    # Add any other required config options
}
builder = MCPServerBuilder(config)
mcp_server = await builder.build()
```

This will create a FastMCP server instance with a GraphQL tool registered, allowing you to interact with the GraphQL API through MCP Composer.

#### Database Configuration for Server Management

When initializing MCPComposer, you can configure the database backend for persistent storage of server configurations:

**Example with Environment Variables (Recommended)**:

```bash
# Set environment variables
export MCP_DATABASE_TYPE="cloudant"
export MCP_DATABASE_API_KEY="your_cloudant_api_key"
export MCP_DATABASE_SERVICE_URL="https://your-cloudant-instance.cloudantnosqldb.appdomain.cloud"
export MCP_DATABASE_DB_NAME="mcp_servers"
```

```python
from mcp_composer import MCPComposer

# Initialize composer - database config will be loaded from environment variables
composer = MCPComposer(name="my-composer")

# Server configurations will be automatically persisted to Cloudant
await composer.setup_member_servers()
```

**Example with Programmatic Cloudant Configuration**:

```python
from mcp_composer import MCPComposer

# Configure Cloudant database programmatically
database_config = {
    "type": "cloudant",
    "api_key": "your_cloudant_api_key",
    "service_url": "https://your-cloudant-instance.cloudantnosqldb.appdomain.cloud",
    "db_name": "mcp_servers"  # Optional
}

# Initialize composer with database configuration
composer = MCPComposer(
    name="my-composer",
    database_config=database_config
)

# Server configurations will be automatically persisted to Cloudant
await composer.setup_member_servers()
```

**Example with Local File Storage**:

```bash
# Option 1: Using environment variables
export MCP_DATABASE_TYPE="local_file"
export MCP_DATABASE_FILE_PATH="/path/to/servers.json"

# Option 2: Enable local file storage when no other config is provided
export MCP_USE_LOCAL_FILE_STORAGE="true"
```

```python
from mcp_composer import MCPComposer

# Option 1: Environment variables will be used automatically
composer = MCPComposer(name="my-composer")

# Option 2: Programmatic configuration
database_config = {
    "type": "local_file",
    "file_path": "/path/to/servers.json"  # Optional
}

composer = MCPComposer(
    name="my-composer",
    database_config=database_config
)

# Server configurations will be stored locally
await composer.setup_member_servers()
```

**Example with No Database (Default)**:

```python
from mcp_composer import MCPComposer

# No database configuration - runs without persistent storage
composer = MCPComposer(name="my-composer")

# Server configurations will not be persisted
await composer.setup_member_servers()
```

**Benefits of Database Configuration**:

- **Persistence**: Server configurations, tools, prompts, and resources are saved across restarts
- **Scalability**: Cloudant provides distributed storage for multi-instance deployments
- **Management**: Tools for enabling/disabling tools, prompts, and resources per server
- **Versioning**: Support for configuration versioning and rollback capabilities

### Command Line Interface (CLI)

MCP Composer can now be launched directly via a CLI using the `mcp-composer` entry point. This provides a lightweight and flexible way to spin up the composer using either HTTP or stdio mode.

#### Usage

```bash
mcp-composer --mode <http|stdio> [--host HOST] [--port PORT] [--log-level LEVEL] [--path PATH] [--config <config.json>]
```

#### Options

| Flag          | Description                                         | Default      |
| ------------- | --------------------------------------------------- | ------------ |
| `--mode`      | Mode to run the Composer in: `http` or `stdio`      | `http`       |
| `--host`      | Host to bind to (for `http` mode)                   | `0.0.0.0`    |
| `--port`      | Port to run on (for `http` mode)                    | `9000`       |
| `--log-level` | Log level (e.g. `debug`, `info`, `warning`)         | `debug`      |
| `--path`      | URL path to mount the MCP Composer on               | `/mcp`       |

### [Demo using MCP Inspector](https://ibm.github.io/mcp-composer/examples/mcp-inspector.html)

1. Run the MCP Inspector as a background process, and take note of the session token/url with token pre-filled:

   ```bash
   npx @modelcontextprotocol/inspector
   ```

   To run a specific version use the following command

   ```bash
   npx @modelcontextprotocol/inspector@0.14.3
   ```

1. Navigate to `mcp-composer/` and create a `.env` file by copying the contents of `.env.example`.Then, set the Server and Tool config path in env file accordingly:

   ```bash
   cp mcp-composer/.env.example mcp-composer/.env
   ```

1. Run the following command

   ```bash
   uv run test/test_composer.py
   ```

1. Open the MCP Inspector in a browser with token pre-filled from the first step above. You can also open on `localhost:6274` and provide the `token` from the first step as the `Proxy Session Token`.

1. set _transport type_ and _URL_ from the previous step above and press `Connect`:

1. We will first use the `register_mcp_server` tool and register `stock_info` MCP server using the bellow config:

   ```json
   {
     "id": "mcp-stock-info",
     "type": "http",
     "endpoint": "https://mcp-stock-info.1vgzmntiwjzl.eu-es.codeengine.appdomain.cloud/mcp"
   }
   ```

# Demo: OAuth

#### 1. Create the environment file

Navigate to `mcp-composer` and create a `.env` file by copying the contents of `.env.example`:

```bash
cp mcp-composer/.env.example mcp-composer/.env
```

#### 2. Configure OAuth credentials

Open `.env` and replace the placeholder values with your actual OAuth provider details (e.g., client ID, client secret, redirect URI, etc.).

#### 3. Run the MCP Composer server

Execute the following command to start the server and test the OAuth integration:

```bash
uv run test/test_composer_oauth.py
```

### MCP Composer Client with Chatbot UI

MCP composer client provides an agent backend service to provide chatbot service that talks with all the tools from MCP Composer server.

A chatbot UI demo is also provided just for testing purpose [Demo-Chatbot-UI]().

#### 1. Setup env variables and configuration

In the same `.env` (copied from `mcp-composer/.env.example`), setup the following variables:

- `CHAT_MODEL_NAME`: watsonx or ollama
- `WATSONX_CHAT_MODEL`: meta-llama/llama-4-maverick-17b-128e-instruct-fp8, ibm/granite-3-3-8b-instruct, etc
- `WATSONX_URL`: Watsonx Instance URL
- `WATSONX_API_KEY`: API-Key of Watsonx instance
- `WATSONX_PROJECT_ID`: Watsonx Project ID
- `CHAT_MODEL_NAME`: local ollama model (if `CHAT_MODEL_NAME=ollama`)

Config file `config/mcp_composer_client.yaml` defines what MCP servers are connected, at current stage, it supports:

- Remote MCP-Composer Server
- Remote SSE/Http MCP-Server (testing purpose)
- Stdio MCP-Server (testing purpose)

Each server config has a boolean field `enabled` to enable the server or disable it.

#### 2. Launch chatbot agent service

(Before running chatbot agent service, make sure all `enabled: true` server in `config/mcp_composer_client.yaml` is properly setup and can be connected.)

- **Option-1. Run agent service in local development environment**

Launch agent service:

```bash
uv run src/mcp_composer_client/acp_server.py
```

It should output agent server URL in terminal:

```bash
INFO:     Waiting for application startup.
INFO:     Application startup complete.
INFO:     Uvicorn running on http://localhost:8000 (Press CTRL+C to quit)
```

- **Option-2. Build and Run Docker Image**

  Build the image, taking default tag as "chatbot":

  ```bash
  docker build -t chatbot -f Dockerfile_Client .
  ```

  Run the image in container interactively (for Windows/Mac), by default, it uses `MCP_BASE_URL` to connect to MCP composer server.

  ```bash
  docker run -it -e HOST=0.0.0.0 -p 8000:8000 chatbot
  ```

  (In Linux, `-e HOST=0.0.0.0` can be removed.)

  If using `config/mcp_composer_client.yaml` to config multiple MCP servers, set env `USER_CONFIG_FILE` to `yes`:

  ```bash
  docker run -it -e USER_CONFIG_FILE=yes -e HOST=0.0.0.0 -p 8000:8000 chatbot
  ```

#### 3. Launch chatbot UI (Optional)

Follow instruction in [Demo-Chatbot-UI](https://github.ibm.com/ai-elite/mcp-composer-chatbot-ui), open browser and input chatbot UI URL. Interact with the chatbot.

## Troubleshooting

### Common Issues

1. **`KeyError: 'SERVER_CONFIG_FILE_PATH'`**
   - **Cause**: Missing environment variable configuration
   - **Solution**: Copy `env.example` to `.env` and set the required environment variables

   ```bash
   cp env.example .env
   ```

2. **`error: Unable to find lockfile at uv.lock`**
   - **Cause**: Missing lock file (first-time setup)
   - **Solution**: Run `uv sync` first to create the initial lock file

   ```bash
   uv sync
   ```

3. **Import errors when testing installation**
   - **Cause**: Environment variables not loaded
   - **Solution**: Ensure `.env` file exists and contains required variables

   ```bash
   # Check if .env file exists
   ls -la .env
   
   # If not, create it
   cp env.example .env
   ```

4. **Package not found when adding as local dependency**
   - **Cause**: Path issues or missing development install
   - **Solution**: Use the full path and install in editable mode

   ```bash
   uv add /full/path/to/mcp-composer --frozen
   uv pip install -e /full/path/to/mcp-composer
   ```

5. **Database configuration not working**
   - **Cause**: Invalid environment variables or missing required parameters
   - **Solution**: Check environment variable format and required parameters

   ```bash
   # Check environment variables
   echo $MCP_DATABASE_TYPE
   echo $MCP_DATABASE_API_KEY
   echo $MCP_DATABASE_SERVICE_URL
   
   # For Cloudant, ensure URL starts with http:// or https://
   export MCP_DATABASE_SERVICE_URL="https://your-instance.cloudantnosqldb.appdomain.cloud"
   
   # For local file storage, ensure file path is valid
   export MCP_DATABASE_FILE_PATH="/path/to/valid/file.json"
   ```

6. **Environment variables not taking effect**
   - **Cause**: Environment variables not properly set or loaded
   - **Solution**: Ensure environment variables are set before running the application

   ```bash
   # Set environment variables in your shell
   export MCP_DATABASE_TYPE="cloudant"
   export MCP_DATABASE_API_KEY="your_key"
   export MCP_DATABASE_SERVICE_URL="https://your-instance.cloudantnosqldb.appdomain.cloud"
   
   # Or add them to your .env file
   echo "MCP_DATABASE_TYPE=cloudant" >> .env
   echo "MCP_DATABASE_API_KEY=your_key" >> .env
   echo "MCP_DATABASE_SERVICE_URL=https://your-instance.cloudantnosqldb.appdomain.cloud" >> .env
   ```

7. **Server fails to start with database configuration errors**
   - **Cause**: Invalid database configuration (missing required fields, invalid URLs, etc.)
   - **Solution**: Fix the database configuration errors

   ```bash
   # Check the error logs for specific database configuration issues
   # Common issues: missing API keys, invalid service URLs, unsupported database types
   
   # For Cloudant, ensure all required fields are set:
   export MCP_DATABASE_TYPE="cloudant"
   export MCP_DATABASE_API_KEY="your_valid_api_key"
   export MCP_DATABASE_SERVICE_URL="https://your-instance.cloudantnosqldb.appdomain.cloud"
   
   # For local file storage:
   export MCP_DATABASE_TYPE="local_file"
   export MCP_DATABASE_FILE_PATH="/path/to/valid/file.json"
   ```

8. **Server starts but some servers are not mounted**
   - **Cause**: Individual server configuration errors (unsupported types, invalid endpoints, etc.)
   - **Solution**: Check logs for mount errors and fix the problematic server configurations

   ```bash
   # Look for "Failed to mount server" messages in the logs
   # Fix the specific server configurations that are failing
   # Server will continue to run with successfully mounted servers
   ```
