Query HeavyBid Data in Claude Desktop

The `list_estimates` and `list_jobs` tools pull active construction projects and their bidding data directly into Claude Desktop. You ask your agent for a specific project status, and it grabs the live estimate details without making you log into the ERP portal. Digging deeper requires exact bid structures. When you need the line-item breakdown, the `get_bid_items` tool returns the precise materials and labor allocations for any estimate. Claude reads this data to compare original bids against active job profiles.

Track Fleet GPS and Meter Readings

The `list_equipment` and `get_equipment_location` tools expose your heavy machinery fleet's real-time GPS coordinates to your AI client. You can ask exactly where a specific excavator is right now, and Claude plots the location based on live telematics. Maintenance schedules depend on usage hours. The `get_equipment_meters` tool fetches the latest odometer and hour readings from the field. You don't guess when a dozer needs service—Claude reads the exact meter count and tells you.

Audit HeavyJob Timecards via MCP Server

The `list_timecards` and `list_employees` tools let your MCP Server read labor hours and crew assignments straight from the field. Claude checks the submitted hours against your active roster to spot unapproved overtime before payroll runs. Cost allocation makes or breaks a project. Using the `list_cost_codes` tool, Claude verifies that field workers are billing their time to the correct earthwork or concrete codes. You catch misallocated labor hours instantly.
