Steel Tools MCP server

• steel_bolt_pretensionFree

  RCSC minimum pretension for A325/A490 structural bolts by diameter, with the turn-of-the-nut rotation when a bolt length is given. Published nominal values for estimating and orientation, not design guidance.

• steel_coating_areaFree

  Surface area to coat for an AISC shape: ft² per foot from the cross-section perimeter, piece/lot area with length and qty, optional interior faces for galvanized tubes and gallons at a supplied coverage rate. Published nominal values for estimating and orientation, not design guidance.

• steel_connection_referenceFree

  Describe a structural steel connection type (behaviour, use, what goes wrong) by name, alias or slug — or look up a structural bolt grade (A325, A490, A307). Published nominal values for estimating and orientation, not design guidance.

• steel_gauge_thicknessFree

  Look up sheet steel gauge thickness (gauges 3-28) in inches and mm with lb/ft², for plain, galvanized or stainless series. Published nominal values for estimating and orientation, not design guidance.

• steel_mtr_checkFree

  Screen a mill cert's yield and tensile against the specified limits for A992, A572 Gr. 50 or A36 — a screening aid, not acceptance. Published nominal values for estimating and orientation, not design guidance.

• steel_ncr_generateFree

  Generate a formal Nonconformance Report PDF: identification, description, the violated requirement, containment, root cause (prose or 5-Whys chain), disposition (accept-as-is/repair/rework/reject) with actions, and blank quality-review and sign-off blocks. Flags accept-as-is dispositions whose corrective action describes physical work. The disposition decision belongs to the responsible quality authority. Returns a download link that expires within ~48 hours. Nothing you submit is stored.

• steel_pdf_markupFree

  Add real Bluebeam-compatible annotation objects to a drawing PDF — counts, length/area measurements with live scales, RFI clouds, callouts — from a markups JSON you supply plus placement coordinates. Pass the PDF as an https URL or small base64; returns a marked PDF download link that expires within ~48 hours. Markups appear in Bluebeam Revu's Markups List. You decide placement; the tool guarantees the format. Nothing you submit is stored.

• steel_pipe_scheduleFree

  Steel pipe dimensions by NPS and schedule: OD, wall, inside diameter and lb/ft for schedules 5, 10, 40/STD, 80/XS, 160 and XXS. Omit the schedule to list them all. Published nominal values for estimating and orientation, not design guidance.

• steel_plate_weightFree

  Compute carbon steel plate weight from thickness (decimal or fraction) and width/length in inches, with optional material cost via price_per_lb. Published nominal values for estimating and orientation, not design guidance.

• steel_rfi_generateFree

  Generate a formal Request for Information PDF from structured fields — header, meta grid, subject, description, proposed solution, attachments, and a blank response block for the design team. You do the judgement (one issue per RFI, exact drawing references, a proposed path forward); the tool guarantees the format. Returns a download link that expires within ~48 hours. Nothing you submit is stored.

• steel_rfq_generateFree

  Generate a vendor-ready Request for Quotation (.xlsx) from structured takeoff line items — grouped by material, with vendor pricing columns, totals and standard terms. You pass parsed line items and a company name; returns a download link that expires within ~48 hours. Nothing you submit is stored.

• steel_section_weightFree

  Weight of round bar, square bar, flat bar or round tube from dimensions in inches — lb/ft and optional piece weight, in carbon, stainless or aluminum. For AISC designations use steel_shape_weight; for plate use steel_plate_weight. Published nominal values for estimating and orientation, not design guidance.

• steel_shape_weightFree

  Look up an AISC shape designation (W, C, MC, L, HSS, PIPE) for lb/ft, depth and area, with optional piece weight. 14th-Edition-era data. Published nominal values for estimating and orientation, not design guidance.

• steel_takeoff_weightFree

  Roll a member list (AISC designation, length in feet, piece count — up to 500 lines) into a bill-of-steel ledger: weight per line, total pounds and tons, piece and lineal-foot counts. Net weight only; unmatched designations are listed, not guessed. Published nominal values for estimating and orientation, not design guidance.
