Install the server via pip and run it:

pip install mcp-server-twelve-data
python -m mcp_server_twelve_data --help

Configuration

Claude Desktop Integration

Add one of the following snippets to your claude_desktop_config.json:

Local stdio server with utool

{
  "mcpServers": {
    "twelvedata": {
      "command": "uvx",
      "args": ["mcp-server-twelve-data@latest", "-k", "YOUR_TWELVE_DATA_API_KEY", "-u", "YOUR_OPEN_AI_APIKEY"]

      "args": ["mcp-server-twelve-data@latest", "-k", "YOUR_TWELVE_DATA_API_KEY", "-n", "10"]
    }
  }
}

Twelve Data remote MCP server

{
  "mcpServers": {
    "twelvedata-remote": {
      "command": "npx",
      "args":    [
        "mcp-remote", "https://mcp.twelvedata.com/mcp",

      ],
      "env": {
        "AUTH_HEADER": "apikey YOUR_TWELVE_DATA_API_KEY",
        "OPENAI_API_KEY": "YOUR_OPENAI_API_KEY"
      }
    }
  }
}

VS Code Integration

Automatic Setup (with UV)

Use the VS Code installer to quickly set up the extension.

Manual Setup

For manual configuration, add to your User Settings (JSON):

{
  "mcp": {
    "servers": {
      "twelvedata": {
          "command": "uvx",
          "args": [
            "mcp-server-twelve-data",
            "-k", "YOUR_TWELVE_DATA_API_KEY",
            "-u", "YOUR_OPENAI_API_KEY"
          ]
        }
    }
  }
}

Troubleshooting

Using the MCP Inspector

For debugging issues, use the MCP Inspector:

npx @modelcontextprotocol/inspector uvx mcp-server-twelve-data@latest -k YOUR_TWELVE_DATA_API_KEY

Docker Usage

Build and run the server using Docker:

docker build -t mcp-server-twelve-data .

docker run --rm mcp-server-twelve-data \
  -k YOUR_TWELVE_DATA_API_KEY \
  -u YOUR_OPENAI_API_KEY \
  -t streamable-http

Using U-tool

U-tool is an AI-powered universal router for the Twelve Data API that allows you to access financial data using natural language. Instead of navigating through complex endpoints and documentation, you can simply describe what you need in plain English.

What You Can Ask

"Show me Apple stock performance this week"
"Calculate RSI for Bitcoin with 14-day period"
"Get Tesla's financial ratios and balance sheet"
"Compare EUR/USD exchange rates over 6 months"
"Find top-performing tech ETFs"

Supported Data Categories

Market data & quotes
Technical indicators (100+)
Fundamental data & financials
Currencies & crypto
Mutual funds & ETFs
Economic calendars & events

To use U-tool, make sure to configure your server with the -u flag and your OpenAI API key as shown in the configuration examples above.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "twelvedata" '{"command":"uvx","args":["mcp-server-twelve-data@latest","-k","YOUR_TWELVE_DATA_API_KEY"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "twelvedata": {
            "command": "uvx",
            "args": [
                "mcp-server-twelve-data@latest",
                "-k",
                "YOUR_TWELVE_DATA_API_KEY"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "twelvedata": {
            "command": "uvx",
            "args": [
                "mcp-server-twelve-data@latest",
                "-k",
                "YOUR_TWELVE_DATA_API_KEY"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
