# Support ### Contact us For help with the CorralData MCP integration, reach out to our support team: **Email**: ### Common issues #### "You don't have permission to use this tool" Your CorralData account doesn't have the required role for that action. Read-only tools (querying data, viewing dashboards) are available to all users. Creating or editing boards and widgets requires the `board.edit` or `widget.edit` role. Contact your CorralData administrator to request access. #### "Could not connect to CorralData" * Check that your organization's CorralData instance is online * Try disconnecting and reconnecting the integration from Claude's settings * If the issue persists, contact your CorralData administrator to verify the MCP server is running #### "Authentication expired" or sign-in prompts Tokens refresh automatically, but long idle periods may require you to sign in again. Simply follow the authentication prompt — your conversation context in Claude is preserved. #### Query returns no results * Verify the table and column names using `describe_table` * Check if a date range filter is needed — some data is time-scoped * Try a simpler query first (e.g., `SELECT * FROM table LIMIT 5`) to confirm the table has data #### Results are truncated SQL results are capped at 1,000 rows by default to keep responses manageable. Use `LIMIT` in your SQL for precise control, or ask Claude to increase the `max_rows` parameter (up to 10,000). ### Feature requests Have an idea for a new tool or improvement?
