Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
Nebula-Block-Data/nebulablock-mcp-serverCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Clone the repository, create and activate a virtual environment, then install dependencies with uv pip install -e .. Run the server using uv run -m src.main. Configure the NebulaBlock API key via the --api-key command-line argument or a .env file containing NEBULA_BLOCK_API_KEY. Finally, configure your MCP client (e.g., VS Code) by adding a server entry in settings.json with the appropriate uv command and arguments.
Claude Desktop / Cursor
Paste into your MCP client config file to install this server.

NebulaBlock API MCP
This repository hosts the official NebulaBlock API Model Context Protocol (MCP) server. This server integrates with the fastmcp library to expose the full range of NebulaBlock API functionalities as accessible tools, enabling seamless and efficient interaction within any MCP-compatible environment.

Installation and Setup
To set up and run this project, follow these steps:
1. Clone the repository (if applicable):
git clone https://github.com/Nebula-Block-Data/api-mcp
cd mcp-project
2. Create a virtual environment:
It's highly recommended to use a virtual environment to manage project dependencies.
python3 -m venv .venv
3. Activate the virtual environment:
macOS/Linux:
source .venv/bin/activate
4. Install dependencies:
This project uses pyproject.toml for dependency management. Install setuptools and then the project in editable mode.
uv pip install -e .
This will install
fastmcp and any other dependencies specified in pyproject.toml.
Running the NebulaBlock API MCP Server
To start the NebulaBlock API MCP server:
uv run -m src.main
You should see output similar to: [05/29/25 17:32:58] INFO Starting MCP server 'FastMCP' with transport 'stdio'
Configuring API Key
The NebulaBlock API key can be configured in two ways:
1. Using the --api-key command-line argument:
You can provide the API key directly when running the application:
python -m src.main --api-key your_nebula_block_api_key
This method will override any API key set in the
.env file.
2. Using a .env file:
Create a file named .env in the root directory of the project and add your API key to it:
NEBULA_BLOCK_API_KEY=your_nebula_block_api_key
The application will automatically load the API key from this file if the
--api-key argument is not provided.
Running Tests
To run the unit tests, ensure your virtual environment is activated and pytest is installed (it will be installed with pip install -e .):
pytest
You should see output indicating that the tests passed.
Integrating with an MCP Client
To utilize the NebulaBlock API MCP server, you need to configure your MCP client (e.g., VS Code with an MCP extension) to connect to this server. Below is an example configuration for a settings.json file:
{
"mcpServers": {
"nebula": {
"command": "~/path/to/uv",
"args": [
"--directory",
"~/path/to/nebulablock_mcp",
"run",
"-m",
"src.main",
"--api-key=YOUR_API_KEY"
]
}
}
}
Replace ~/path/to/uv with the actual path to your uv executable.
Replace ~/path/to/nebulablock_mcp with the actual path to your project directory.
- Replace
YOUR_API_KEYwith your actual NebulaBlock API key.
