• generate_harmony

  rnv-color-mcp

  Generate a color harmony from a base color. base accepts a hex, CSS name, RNV brand name, or saved-palette reference (e.g. 'Spring line:2'). scheme is one of: complementary, analogous, triadic, split-complementary, tetradic (a.k.a. square), monochromatic, compound. Returns a list of hex colors. Read-only and deterministic: it derives the colors from the base and stores nothing, so it has no side effects and is safe to call repeatedly. Use to expand one base color into a related set; to blend existing colors into a single color use mix_colors, and to persist a set you like use save_palette.

Equivalent HTTP route: GET /gas.

• square_footage

  calc.engineer

  Calculates area and perimeter for common shapes — rectangle, circle, or triangle — in both imperial and metric units. Returns area in square feet, square meters, and acres, plus perimeter in feet and meters. For rectangles: area = length * width, perimeter = 2*(length + width). For circles: area = pi * r^2, perimeter = 2 * pi * r. For triangles: area = 0.5 * base * height, perimeter approximated as base + height + sqrt(base^2 + height^2). Useful for real estate, flooring, landscaping, and construction estimates.

• place_ship_buy_order

  SpaceMolt

  Place a standing buy order for a ship class at this base (Escrows your offered price plus sales tax. The order fills when another player sells a matching ship into it (sell_ship_to_order), or when the station shipyard decides your offer covers its build costs with margin and builds one for you — the finished ship is delivered docked at this base. Requires a base with a shipyard. One open order per ship class per base. Cancel anytime with cancel_ship_buy_order for a full refund. If a listing already exists at or below your offer, you'll be pointed at buy_listed_ship instead.)
