MCP Client Configuration (Recommended)
Your MCP client handles all environment setup. Add the credentials to your client's configuration file as shown in the Installation section above. Most MCP clients follow a similar JSON configuration format.

Local Development Only
If you're developing or testing the server directly (outside of an MCP client), create a .env file:
`bash
cp .env.example .env


Edit .env with your credentials


`

Response Format Options

Many tools support parameters to control the shape and size of responses, helping you manage context tokens:

| Parameter | Values | Description |
|-----------|--------|-------------|
| output_format | friendly (default), raw | Controls how output is formatted. Friendly returns human-readable text; raw returns JSON. |
| detail_level | concise (default), full | Controls how much data is returned. Concise includes essential fields; full includes all fields. |

Available combinations:

- Friendly format (default): Human-readable text, always concise
- Raw + concise: Reduced JSON with essential fields only
- Raw + full: Complete JSON with all fields from the API

The detail_level parameter only applies when output_format is set to raw. Friendly format is always concise by design.

How It Works

1. Authentication: The server automatically authenticates with EPCC using your credentials
2. Token Management: Access tokens are refreshed automatically as needed
3. Query Processing: Your questions are converted to EPCC Data Warehouse API calls
4. Data Formatting: Results are formatted for easy reading

Troubleshooting

Tools don't appear in my client
- Check that your MCP client configuration is valid JSON
- Verify the path to dist/src/local.js is correct
- Make sure you've run npm run build

"EPCC is not configured" error
- Double-check your EPCC_CLIENT_ID, EPCC_CLIENT_SECRET, and EPCC_BASE_URL
- Ensure your EPCC application has the necessary permissions

"No data returned" responses
- Verify your date ranges use the correct format (RFC3339 with milliseconds)
- Check that you have data for the requested time period
- Ensure your EPCC client has access to the Data Warehouse service

Connection timeouts
- Your EPCC application may need Data Warehouse API access enabled
- Check your EPCC application's rate limits

Development

Build the server:
`bash
npm run build
`

Run with debugging:
`bash
npm run debug
`

Watch mode for development:
`bash
npm run dev
``

Requirements

- Node.js 18 or later
- An EPCC account with Data Warehouse access
- MCP-compatible client (such as Claude Desktop, Continue, or any client supporting the Model Context Protocol)
