Description, as the server wrote it
What size generator you need for a power outage: add the running watts of everything you will run at once, then add the single biggest motor starting surge. Enter how many of each item you plan to run at the same time. Formula: Total running watts = Σ (quantity × running watts). Total starting watts = total running watts + the single highest additional starting watts among the items you run, because motors rarely start at the same instant. Amps at 240 V = running watts ÷ 240. Margin is an optional buffer you choose.

Description, as the server wrote it
How much grout a tile job takes from the tile size, joint width, joint depth and area, in pounds and bags. The grout density is editable so you can match your product. Formula: Each tile plus its joint is a (L + J) × (W + J) module, of which J × (L + W + J) is joint. Joint share = J(L + W + J) ÷ ((L + J)(W + J)). Grout volume (cu ft) = area × joint share × depth(in) ÷ 12; pounds = volume × density × (1 + waste); bags = ⌈pounds ÷ bag size⌉.

- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Check whether a gutter can carry the runoff from your roof in a design storm, and how many downspouts it needs. Uses the USDA NRCS gutter and downspout capacity table and your local rainfall intensity. Formula: Runoff Q (cfs) = roof area (sq ft) × rainfall intensity (in/hr) ÷ 43,200 (12 in/ft × 3,600 s/hr); gpm = cfs × 448.8. The gutter is adequate when Q ≤ its NRCS PA-1 capacity at your slope. Downspouts = the larger of ⌈Q ÷ one downspout's PA-1 capacity⌉ and ⌈run length ÷ max length per downspout⌉. Max roof area for the gutter = capacity × 43,200 ÷ intensity.

Description, as the server wrote it
How much calcium chloride raises your pool's calcium hardness, or how much water to replace to lower it, based on your pool size and fill-water hardness. Formula: Raise: calcium chloride (lb) = (target − current) ÷ 10 × gallons ÷ 10,000 × 1.2 for 77% (0.9 for 100%).

Description, as the server wrote it
How much rebar a rectangular slab grid needs: bar count each way, lap splices, total linear feet, 20 ft sticks to order and steel weight from ASTM A615 bar weights. Formula: Bars each way = ⌊(clear span ÷ spacing)⌋ + 1, where clear span = side × 12 − 2 × edge clearance. A run longer than one stick needs ⌈(run − lap) ÷ (stick − lap)⌉ pieces, adding one lap per joint; lap = bar diameters × bar diameter. Linear ft = (bars × run + splices × lap) ÷ 12; sticks = ⌈linear ft × (1 + allowance) ÷ stick length⌉; weight = linear ft × ASTM A615 lb/ft.

Description, as the server wrote it
How many retaining wall blocks you need for a straight wall or a circle (fire pit, tree ring), including the buried course, cap units, base gravel for the leveling pad and drainage rock behind the wall. Block sizes are editable because every product line differs. Formula: Buried depth = max(exposed height ÷ bury ratio, minimum). Courses = ⌈(exposed height + buried depth − cap height) ÷ block height⌉. Blocks per course = ⌈run ÷ block face length⌉, where run = wall length, or π × outside diameter for a circle. Wall blocks = ⌈blocks per course × courses × (1 + waste%)⌉; caps = ⌈run ÷ cap length × (1 + waste%)⌉. Base gravel cu yd = run(ft) × trench width(in) × base depth(in) ÷ 144 ÷ 27; drainage rock cu yd = run(ft) × zone depth(in) × stacked block height(in) ÷ 144 ÷ 27 (straight walls only).

Description, as the server wrote it
Roof area from the house footprint and pitch, converted to roofing squares (100 sq ft) and shingle bundles. Formula: Pitch factor = √(1 + (rise/12)²). Roof area = (L + 2×overhang) × (W + 2×overhang) × pitch factor. Squares = area ÷ 100 × (1 + waste%).

Description, as the server wrote it
Minimum septic tank size, pump tank size and drainfield area for a single-family home under Florida Rule 62-6.008, from bedrooms, building area and soil type. Formula: Design flow = the larger of the bedroom flow (100 gpd per bedroom up to 4, then +60 per bedroom) and the building-area flow (100 gpd to 750 sq ft, 200 to 1,200, 300 to 2,250, 400 to 3,300, then +60 per extra 750 sq ft or fraction), per Table I and its footnote 4. Septic tank and pump tank minimums come from Table II for that flow. Drainfield area = max(flow, 200 gpd) ÷ the Table III loading rate for the soil and trench or bed.

Description, as the server wrote it
Square feet of sod, number of pieces and pallets for a lawn area. Piece size and pallet coverage are editable because they vary by farm and grass type. Formula: Sq ft to buy = L × W × (1 + waste%); pieces = sq ft ÷ (piece length × width ÷ 144); pallets = sq ft ÷ pallet coverage.

Description, as the server wrote it
Panels needed to offset annual electricity use, from panel wattage, peak sun hours and system losses. Formula: Annual kWh per panel = W/1000 × peak sun hours × 365 × (1 − losses). Panels = ⌈annual use ÷ kWh per panel⌉.

Number of risers and treads, exact riser height, total run and stringer length from the floor-to-floor rise, checked against the IRC 7¾ in maximum riser.

47 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
