Local Installation And Development

1. Install dependencies:

   npm install

2. Build the project:

   npm run build

This will create a dist directory containing the compiled JavaScript files.

3. To use the local development version of MCP server instead of the published version, you can run the server directly from the local build:

   npm run build

   Modify the MCP server configuration file in any of the clients (Claude, Cursor)

    {
      "mcpServers": {
        "Harvest": {
          "command": "node",
          "args": [
            "path/to/local/build/dist/index.js"
          ],
          "env": {
            "HARVEST_ACCOUNT_ID": "<Harvest Account ID>",
            "HARVEST_ACCESS_TOKEN": "<Harvest Personal Access Token>",
            "HARVEST_BASE_URL": "<Harvest Base URL>"
          }
        }
      }
    } 

4. Restart the client application (Claude, Cursor) to apply the changes and test the latest changes without publishing a new version.
