Installation

For Claude Desktop Users

If you're using Claude Desktop, you only need to add the following configuration to your MCP config file:

"harvest": {
  "command": "docker",
  "args": [
    "run",
    "-i",
    "--rm",
    "-e",
    "HARVEST_ACCOUNT_ID",
    "-e",
    "HARVEST_TOKEN",
    "tommcl/harvest-mcp"
  ],
  "env": {
    "HARVEST_ACCOUNT_ID": "YOUR_ACCOUNT_ID",
    "HARVEST_TOKEN": "YOUR_API_TOKEN"
  }
}

Note: You need to have Docker Desktop installed and running.

Credentials: You can obtain your Personal Access Token (PAT) and Account ID from the Harvest Developer Tools page.

Option 1: Pull from Docker Hub (For Other MCP Clients)

1. Pull the Docker image directly from Docker Hub:

   docker pull tommcl/harvest-mcp
   

Option 2: Build Locally (For Development)

1. Clone the repository:

   git clone https://github.com/yourusername/harvest-mcp.git
   cd harvest-mcp
   

2. Build the Docker image:

   docker build -t mcp/harvest .
   

   Then use "mcp/harvest" instead of "tommcl/harvest-mcp" in your MCP config.

   Note: Replace the example credentials with your actual Harvest API credentials. You can obtain your Personal Access Token (PAT) and Account ID from the Harvest Developer Tools page.
