Usage

Claude Desktop

• Open the Claude desktop config file claude-desktop-config.json and set the following details under mcpServers.

  {
    "mcpServers": {
      "Harvest": {
        "command": "npx",
        "args": [
          "@harvest/mcp-server-typescript",
          // Or use the path to the local build
          // "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>"
        }
      }
    }
  }
  

Cursor IDE

  {
    "mcpServers": {
      "Harvest": {
        "command": "npx",
        "args": [
          "@harvest/mcp-server-typescript",

    }
  }
  

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.
