hex-mcp MCP server

A MCP server for Hex that implements the following tools:

• list_hex_projects: Lists available Hex projects
• search_hex_projects: Search for Hex projects by pattern
• get_hex_project: Get detailed information about a specific project
• get_hex_run_status: Check the status of a project run
• get_hex_project_runs: Get the history of project runs
• run_hex_project: Execute a Hex project
• cancel_hex_run: Cancel a running project

Installation

Using uv is the recommended way to install hex-mcp:

uv add hex-mcp

Or using pip:

pip install hex-mcp

To confirm it's working, you can run:

hex-mcp --version

Configuration

Using the config command (recommended)

The easiest way to configure hex-mcp is by using the config command and passing your API key and API URL (optional and defaults to https://app.hex.tech/api/v1):

hex-mcp config --api-key "your_hex_api_key" --api-url "https://app.hex.tech/api/v1"

[!NOTE] This saves your configuration to a file in your home directory (e.g. ~/.hex-mcp/config.yml), making it available for all hex-mcp invocations.

Using environment variables

Alternatively, the Hex MCP server can be configured with environment variables:

• HEX_API_KEY: Your Hex API key
• HEX_API_URL: The Hex API base URL

When setting up environment variables for MCP servers they need to be either global for Cursor to pick them up or make use of uv's --env-file flag when invoking the server.

Using with Cursor

Cursor allows AI agents to interact with Hex via the MCP protocol. Follow these steps to set up and use hex-mcp with Cursor. You can create a .cursor/mcp.json file in your project root with the following content:

{
  "mcpServers": {
    "hex-mcp": {
      "command": "uv",
      "args": ["run", "hex-mcp", "run"]
    }
  }
}

Alternatively, you can use the hex-mcp command directly if it's in your PATH:

{
  "mcpServers": {
    "hex-mcp": {
      "command": "hex-mcp",
      "args": ["run"]
    }
  }
}

Once it's up and running, you can use it in Cursor by initiating a new AI (Agent) conversation and ask it to list or run a Hex project.

[!IMPORTANT] The MCP server and CLI is still in development and subject to breaking changes.
