Repository containing reference implementations of MCP (Model Context Protocol) servers for managing and interacting with Oracle products. Each MCP server under src/ may be written in a different programming language, demonstrating MCP’s language-agnostic approach.

The Model Context Protocol (MCP) enables standardized, language-agnostic machine-to-machine workflows across data, models, and cloud resources. MCP servers implement specific tool suites, exposing them to MCP-compatible clients.

• Proof-of-concept/Reference implementations:
  This repository is not intended for production use; servers are provided as reference and for exploration, prototyping, and learning.

• Polyglot architecture:
  Each src/<server-name>/ directory represents a distinct MCP server, and these may use Python, Node.js, Java, or other languages.

• Supported OS: Linux, macOS, or Windows (varies by server; check server README)
• Git (for cloning this repository)
• Internet access (for downloading dependencies)
• Cloud access: Some servers require Oracle Cloud Infrastructure (OCI) credentials and configuration (OCI docs)

Note:
Each MCP server has its own specific requirements (e.g., language runtime version, libraries).
Always see the respective src/<server>/README.md for detailed setup instructions.

Follow these instructions to get started as quickly as possible. Once finished, look here to set up your local development environment if you wish to contribute changes.

1. Install uv from here
2. Install python with uv python install 3.13
3. If you are using OCI servers, configure your OCI authentication
4. Add desired servers to your MCP client configuration

Below is an example MCP client configuration for a typical python server

(For Node.js/Java/other servers, follow respective instructions in that server’s README)

For macOS/Linux:

{
  "mcpServers": {
    "oracle-oci-api-mcp-server": {
      "command": "uvx",
      "args": [
        "oracle.oci-api-mcp-server@latest"
      ],
      "env": {
        "FASTMCP_LOG_LEVEL": "ERROR"
      }
    }
  }
}

For OCI MCP servers, you'll need to install and authenticate using the OCI CLI.

1. Install the OCI CLI
2. Configure your OCI CLI profile

oci session authenticate --region=<region> --tenancy-name=<tenancy_name>

where: <region> is the region you would like to authenticate in (e.g. us-phoenix-1) <tenancy_name> is the name of your OCI tenancy

Some MCP servers may not work with token-based authentication alone. See more about API key-based authentication here.

All actions are performed with the permissions of the configured OCI CLI profile. We advise least-privilege IAM setup, secure credential management, safe network practices, secure logging, and warn against exposing secrets.

Remember to refresh the session once it expires with:

oci session authenticate --profile-name <profile_name> --region <region> --auth security_token

<profile_name> is the profile that you set up in the steps above. You can view a list of your profiles by running cat ~/.oci/config on macOS/Linux if you forget which profile you have set up.

Each MCP server exposes endpoints that your client can connect to. To enable this connection, just add the relevant server to your MCP client’s configuration file. You can find the list of servers under the src folder.

Refer to the sections below for client-specific configuration instructions.

{
  "mcpServers": {
    "oracle-oci-api-mcp-server": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "oracle.oci-api-mcp-server@latest"
      ],
      "env": {
        "OCI_CONFIG_PROFILE": "<profile_name>",
        "FASTMCP_LOG_LEVEL": "ERROR"
      }
    }
  }
}

{
  "mcpServers": {
    "oracle-oci-api-mcp-server": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "oracle.oci-api-mcp-server"
      ],
      "env": {
        "OCI_CONFIG_PROFILE": "<profile_name>",
        "FASTMCP_LOG_LEVEL": "ERROR"
      }
    }
  }
}

{
  "mcpServers": {
    "oracle-oci-api-mcp-server": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "oracle.oci-api-mcp-server"
      ],
      "env": {
        "OCI_CONFIG_PROFILE": "<profile_name>",
        "FASTMCP_LOG_LEVEL": "ERROR"
      }
    }
  }
}

This section will help you set up your environment to prepare it for local development if you wish to contribute changes.

1. Set up python virtual environment and install dev requirements

   python3 -m venv venv
   source venv/bin/activate        # On Windows: venv\Scripts\activate
   pip install -r requirements-dev.txt

2. Locally build and install servers within the virtual environment

   make build
   make install

3. Add desired servers to your MCP client configuration, but run them using the locally installed server package instead

Below is an example MCP client configuration for a typical python server using the local server package

(For Node.js/Java/other servers, follow respective instructions in that server’s README)

For macOS/Linux:

{
  "mcpServers": {
    "oracle-oci-api-mcp-server": {
      "command": "uv",
      "args": [
        "run"
        "oracle.oci-api-mcp-server"
      ],
      "env": {
        "VIRTUAL_ENV": "<path to your cloned repo>/mcp/venv",
        "FASTMCP_LOG_LEVEL": "ERROR"
      }
    }
  }
}

where <path to your cloned repo> is the absolute path to wherever you cloned this repo that will help point to the venv created above (e.g. /Users/myuser/dev/mcp/venv)

.
├── src/

Each server subdirectory includes its own README.md with language/runtime details, installation, and usage.

You can modify the settings of your MCP client to run your local server. Open your client json settings file and update it as needed. For instance:

{
  "mcpServers": {
    "oracle-oci-api-mcp-server": {
      "type": "stdio",
      "command": "uv",
      "args": [
        "run",
        "oracle.oci-api-mcp-server"
      ],
      "env": {
        "VIRTUAL_ENV": "<path to your cloned repo>/oci-mcp/.venv",
        "FASTMCP_LOG_LEVEL": "ERROR"
      }
    }
  }
}

where <absolute path to your server code> is the absolute path to the server code, for instance /Users/myuser/dev/oci-mcp/src/oci-identity-mcp-server/oracle/oci_identity_mcp_server.

The Model Context Protocol (MCP) provides Inspector which is a developer tool for testing and debugging MCP servers. More information on Inspector can be found in the documentation.

The Inspector runs directly through npx without requiring installation. For instance, to inspect your locally developed server, you can run:

npx @modelcontextprotocol/inspector \
  uv \
  --directory <absolute path to your server code> \
  run \
  server.py

Inspector will run your server on localhost (for instance: http://127.0.0.1:6274) which should automatically open the tool for debugging and development.
