MCP Server for Oracle Cloud Infrastructure (OCI)

This project implements a Model Context Protocol (MCP) server for Oracle Cloud Infrastructure, allowing LLMs like Claude to interact directly with OCI resources.

presentation

Features

  • Dynamic Profile Selection: Switch between OCI profiles/tenancies without restarting the server

  • Connection to Oracle Cloud using standard OCI CLI configuration

  • Comprehensive tools to list and manage OCI resources

  • Instance lifecycle management (start, stop)

  • Database Systems and DB Nodes management

  • Integration with the MCP protocol to facilitate access from Claude Desktop

Prerequisites

  • Python 3.10 or higher

  • OCI CLI configured (oci setup config)

  • Appropriate permissions in Oracle Cloud

Installation

Clone this repo

pip install git+https://github.com/modelcontextprotocol/python-sdk.git pip install oci fastapi uvicorn click pydantic loguru pip install -e .

Usage

Starting the Server

Option 1: Dynamic Profile Selection (Recommended)

Start without a profile and select it at runtime:

python -m mcp_server_oci.mcp_server

Then use the MCP tools to manage profiles:

  • list_oci_profiles - See available profiles from ~/.oci/config

  • set_oci_profile - Activate a specific profile

  • get_current_oci_profile - Check which profile is active

Option 2: With Default Profile

Start with a specific profile pre-loaded:

python -m mcp_server_oci.mcp_server --profile DEFAULT

With uv:

uv --directory /path/to/mcp-server-oci run python -m mcp_server_oci.mcp_server --profile DEFAULT

Switching Between Tenancies

You can switch between different OCI tenancies without restarting:

# In your MCP client (e.g., Claude): # 1. List available profiles "Show me available OCI profiles" # 2. Switch to a different tenancy "Switch to the 'production' OCI profile" # 3. Verify current profile "What OCI profile am I using?"

Configuration for Claude Desktop (MacOS)

Add this configuration to your file: /Users/<usuario>/Library/Application Support/Claude/claude_desktop_config.json

With dynamic profile selection (recommended):

"mcpServers": { "mcp-server-oci": { "command": "python", "args": [ "-m", "mcp_server_oci.mcp_server" ], "env": { "PYTHONPATH": "/<PATH_TO_MCP>/mcp-server-oci", "FASTMCP_LOG_LEVEL": "INFO" } } }

With fixed profile:

"mcpServers": { "mcp-server-oci": { "command": "python", "args": [ "-m", "mcp_server_oci.mcp_server", "--profile", "DEFAULT" ], "env": { "PYTHONPATH": "/<PATH_TO_MCP>/mcp-server-oci", "FASTMCP_LOG_LEVEL": "INFO" } } }

With

"mcpServers": { "mcp-server-oci": { "command": "uv", "args": [ "--directory", "/<PATH_TO_MCP>/mcp-server-oci", "run", "python", "-m", "mcp_server_oci.mcp_server" ], "env": { "FASTMCP_LOG_LEVEL": "INFO" } } }

💡 Usage Examples

Profile Management

# From Claude or any MCP client: # List available profiles "Show me all available OCI profiles" # Activate a specific profile "Set the OCI profile to 'production'" # Check current profile "What OCI profile am I currently using?" # Switch between tenancies "Switch to the DEFAULT profile"

Compute Instance Management

# List instances "Show me all compute instances in compartment ocid1.compartment.oc1..." # Get instance details "Get details for instance ocid1.instance.oc1..." # Start/stop instances "Start the instance ocid1.instance.oc1..." "Stop the instance ocid1.instance.oc1... with force stop"

Database Systems Management

# List DB Systems "Show me all DB Systems in compartment ocid1.compartment.oc1..." # Get DB System details "Get details for DB System ocid1.dbsystem.oc1..." # Manage DB Nodes "List all DB Nodes for DB System ocid1.dbsystem.oc1..." "Start DB Node ocid1.dbnode.oc1..." "Stop all nodes of DB System ocid1.dbsystem.oc1..." # Reboot operations "Reboot DB Node ocid1.dbnode.oc1..." "Soft reset DB Node ocid1.dbnode.oc1..."

Resource Discovery

# List compartments "List all compartments in my tenancy" # Cross-resource queries "Show me all running instances in compartment X" "List all DB Systems and their current states"

🚀 Recent Improvements

v1.5 - Dynamic Profile Selection (Latest) 🔥

  • Multi-tenancy support: Switch between OCI profiles without restarting

📚 Documentation

🤝 Contributing

Contributions are welcome! The codebase follows these patterns:

  • Hybrid error handling (raise for technical errors, return dict for business states)

  • Async operations (no blocking calls)

  • Centralized configuration (constants in config.py)

  • DRY principle (use decorators for common patterns)
