run

Run MCP servers from installed packages or configuration files.

fluidmcp run <package|all|file> [options]

Examples:

fluidmcp run Airbnb/airbnb@0.1.0 --port 8200 --start-server

# Run all installed packages
fluidmcp run all

# Run with master S3 configuration
fluidmcp run all --master

# Run from local configuration file
fluidmcp run <path-to-your-directory>config.json --file

# Run from S3 presigned URL
fluidmcp run https://s3.amazonaws.com/bucket/config.json --s3

# Run with secure mode and custom token
fluidmcp run Fluid_Ai/jupyter@1.0.0 --secure your-bearer-token --port 8200 --start-server

Options:

• --port <number>: Specify port for SuperGateway (default: 8111)

Configuration

Environment Variables

FluidMCP CLI uses several environment variables for configuration:

# S3 Configuration (for --master mode)
export S3_BUCKET_NAME="your-bucket"
export S3_ACCESS_KEY="your-access-key"
export S3_SECRET_KEY="your-secret-key"
export S3_REGION="us-east-1"

# Registry configuration
export MCP_FETCH_URL="https://registry.fluidmcp.com/fetch-mcp-package"
export MCP_TOKEN="your-registry-token"

---

Package Structure

Installed packages follow this directory structure:

.fmcp-packages/
├── author1/
│   └── package1/
│       └── 1.0.0/
│           ├── metadata.json
│           └── [package files]
└── author2/
    └── package2/
        └── 2.1.0/
            ├── metadata.json
            └── [package files]

---

Metadata Format

Each package contains a metadata.json file:

{
  "mcpServers": {
    "package-name": {
      "command": "npx",
      "args": ["-y", "@package/server"],
      "env": {
        "API_KEY": "value"
      }
    }
  }
}

---

S3 Files

For S3 operations, you can use following Json format:

{
  "mcpServers": {
    "server1": {
      "command": "npx",
      "args": ["-y", "example-package@1.0.0"],
      "env": {
        "API_KEY": "your-api-key"
      },
      "port": "8100",
      "install_path": "/path/to/.fmcp-packages/Author/package/1.0.0",
      "fmcp_package": "Author/package@1.0.0"
    },
    "server2": {
      "command": "uvx",
      "args": ["another-server"],
      "env": {
        "TOKEN": "value"
      },
      "port": "8101",
      "install_path": "/path/to/.fmcp-packages/Author/another-package/2.0.0",
      "fmcp_package": "Author/another-package@2.0.0"
    }
  }
}

Advanced Usage

Master Mode

Master mode allows centralized management of MCP servers using S3 storage:

# Install package for master mode (skips env prompts)
fluidmcp install package --master

# Run all servers using S3 configuration
fluidmcp run all --master

In master mode:

• Environment variables are managed via a central .env file
• Server metadata is stored in S3 (s3_metadata_all.json)
• Automatic synchronization across multiple environments

---

Secure Mode

Enable secure mode for production deployments:

# Run with auto-generated token
fluidmcp run package --secure

# Run with custom token
fluidmcp run package --secure --token your-custom-token

Secure mode features:

• Bearer token authentication
• Encrypted communication between servers
• Environment variable injection for security tokens

---

Port Management

FluidMCP automatically manages ports to avoid conflicts:

• Scans for available ports in range 8100-9000
• Kills existing processes when using --force-reload
• Assigns unique ports to each server in multi-server setups

---

API Registry

FluidMCP CLI connects to the FluidMCP registry to download packages. The registry provides:

• Package versioning and metadata
• Secure package distribution via S3 pre-signed URLs
• Authentication and authorization
• Package discovery and search
