GitHub - G-Core/gcore-mcp-server: Gcore official MCP server (original) (raw)

Gcore MCP Server

MCP (Model Context Protocol) server for Gcore API. This server provides tools for interacting with Gcore Cloud API via LLM assistants.

Usage

Note: As we have multiple resources available, providing all of them at once to the LLM can overwhelm it and lead to confusion among the tools. It is recommended to specify only the necessary resources for your task to ensure optimal performance and clarity.

Integration with Cursor IDE

Add the server to your Cursor IDE configuration file (~/.cursor/mcp.json):

{ "mcpServers": { "gcore-mcp-server": { "command": "uvx", "args": ["--from", "gcore-mcp-server@git+https://github.com/G-Core/gcore-mcp-server.git", "gcore-mcp-server"], "env": { "GCORE_API_KEY": "4**1", "GCORE_TOOLS": "instances,management,cloud.gpu_baremetal_clusters." } } } }

Note: You can find instructions on how to obtain a Gcore API Key here.

Optional variables:

Configuration

Tool Selection

The server uses a unified configuration approach via the GCORE_TOOLS environment variable. This single variable can contain a mix of predefined toolset names and custom patterns:

Mixed toolsets and patterns

export GCORE_TOOLS="instances,management,cloud.gpu_baremetal_clusters.*,dns.records.create"

Only toolsets

export GCORE_TOOLS="instances,management"

Only patterns

export GCORE_TOOLS="cloud.,waap."

Default behavior (if not set)

Uses "management,instances" toolsets for HTTP mode, "management" for stdio

Configuration Modes

  1. Default Mode (no configuration)
    • HTTP transport: Uses management,instances toolsets
    • stdio transport: Uses management toolset
  2. Toolset Mode (predefined tool collections)
    • Use predefined toolset names: instances, management, ai_ml, etc.
    • Example: GCORE_TOOLS="instances,management"
  3. Pattern Mode (custom tool filtering)
    • Use wildcard patterns to match tool names from the Gcore SDK
    • Exact matches: cloud.instances.create, dns.records.delete
    • Wildcard matches: cloud.*, waap.*, cloud.gpu_baremetal_clusters.*
    • Example: GCORE_TOOLS="cloud.instances.*,waap.*"
  4. Combined Mode (toolsets + patterns)
    • Mix predefined toolsets with custom patterns
    • Toolset definitions have priority over pattern matches
    • Example: GCORE_TOOLS="instances,cloud.gpu_baremetal_clusters.*"

Available Toolsets

The system includes several predefined toolsets for common workflows:

Pattern Syntax

Patterns support wildcard matching using *:

Priority System

When using combined mode:

  1. Toolset tools are included first (highest priority)
  2. Pattern-matched tools are added second
  3. Duplicates are removed while preserving order
  4. Toolset definitions take precedence over pattern matches

Examples

Development: Get specific tools for testing

export GCORE_TOOLS="cloud.instances.create,cloud.instances.delete,cloud.volumes.create"

Full cloud management

export GCORE_TOOLS="management,instances,volumes,networks"

GPU cluster operations with custom additions

export GCORE_TOOLS="gpu_baremetal,cloud.instances.create,waap.*"

All services with wildcard

export GCORE_TOOLS="cloud.,waap."

Minimal setup

export GCORE_TOOLS="instances"

Running in a Temporary Environment (One-off Execution)

If you want to run the server without installing it persistently (e.g., for a quick test or a single use), you can use uvx. This command fetches the package, runs the specified script in a temporary environment, and then discards the environment.

To run the latest version from the main branch:

uvx --from "gcore-mcp-server@git+https://github.com/G-Core/gcore-mcp-server.git" gcore-mcp-server

To run a specific version (e.g., v0.1.1):

uvx --from "gcore-mcp-server@git+https://github.com/G-Core/gcore-mcp-server.git@v0.1.1" gcore-mcp-server

Remember to set any required environment variables (like GCORE_API_KEY, GCORE_TOOLS, etc.) before running the command.

Persistent Installation (Installing as a Tool)

For detailed installation instructions for uv, please refer to the official uv installation guide.

You can install gcore-mcp-server as a command-line tool using uv. This makes the command available globally in your terminal without needing to specify the source each time.

To install the latest version from the main branch:

uv tool install "gcore-mcp-server@git+https://github.com/G-Core/gcore-mcp-server.git"

To install a specific version (e.g., v0.1.0):

uv tool install "gcore-mcp-server@git+https://github.com/G-Core/gcore-mcp-server.git@v0.1.0"

After installation, uv will make the gcore-mcp-server command available. If it's not immediately found, you might need to run uv tool update-shell or ensure uv's tool bin directory is in your PATH.

Once installed, you can run it like any other command:

Development

Local Development Setup

Clone the repository

git clone https://github.com//G-Core/gcore-mcp-server.git cd gcore-mcp-server

Install development dependencies

uv venv source .venv/bin/activate uv sync --dev

Debugging and Testing

For debugging and development, it's recommended to use the MCP Inspector:

npx @modelcontextprotocol/inspector

The MCP Inspector provides a web interface to test and debug your MCP server interactively, allowing you to:

To use it with your local development server:

  1. Start your MCP server locally
  2. Run the inspector and connect to your server
  3. Use the web interface to test your tools
