37 cutting and woodworking calculators: cut lists, sheet nesting, timber volume, kiln drying
Scored across 37 tools
Most tools target a distinct calculation domain, but a few pairs are easy to confuse: cutting_speed_calculator and rpm_calculator are near-inverses, cnc_feeds_speeds overlaps with both, and log_volume/hoppus_volume/jas_log_scale all compute log volume differently. Descriptions are explicit enough to disambiguate with careful reading, but the overlap creates minor selection risk.
The set nearly always uses snake_case with a descriptive noun or domain prefix, and most tools end in _calculator or _optimizer. However, several tools use bare nouns (bom_costing, cbm_shipment, wood_emc) or different suffixes (_takeoff, _recovery, _factor), so the pattern is not perfectly uniform.
At 37 tools, the set exceeds the 25-tool threshold for 'too many' and will force agents to scan a large surface for selection. Even though each calculator is individually focused, the breadth across woodworking, shipping, CNC, and materials makes the overall tool set heavy for a single MCP server.
The tool set covers the stated calculator domain broadly: woodworking, lumber/log scaling, moisture, cutting optimization, shipping, and material takeoffs are all represented. Minor gaps exist—such as no concrete, roof, or stair calculators—but for the apparent scope, the surface is quite complete with no critical dead ends.
