Connect Steel Tools and your agent gets 14 tools, among them steel_bolt_pretension, steel_coating_area, steel_connection_reference. It answers at https://www.structupath.ai/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 4 September 2026; the last check, on 17 October 2026, succeeded.
Read-only steel calculators: gauge, plate, shapes, bar/tube, pipe schedule, bolts, MTR checks.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
steel_bolt_pretension | 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. Inputs: dia, length_in |
steel_coating_area | 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 es Inputs: designation, length_ft, qty, include_inside_faces, coverage_sqft_per_gal |
steel_connection_reference | 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. Inputs: name_or_slug |
steel_gauge_thickness | 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. Inputs: gauge, material |
steel_mtr_check | 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. Inputs: grade, yield_ksi, tensile_ksi |
steel_ncr_generate | 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 Inputs: company_name, company_location, ncr_number, date, project_name, project_number |
steel_pdf_markup | 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 ba Inputs: pdf_url, pdf_base64, markups, scale, page_scales, coordinate_space |
steel_pipe_schedule | 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 Inputs: nps, schedule |
steel_plate_weight | 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. Inputs: thickness_in, width_in, length_in, price_per_lb |
steel_rfi_generate | 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 d Inputs: company_name, company_location, rfi_number, date, project_name, project_number |
steel_rfq_generate | 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 t Inputs: company_name, company_location, project_name, project_location, date_issued, line_items |
steel_section_weight | 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 Inputs: section, dim1_in, dim2_in, length_ft, material |
steel_shape_weight | 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. Inputs: designation, length_ft, qty |
steel_takeoff_weight | 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 Inputs: members |

It answered our last check on 17 October 2026 in 277 ms. Over 10 checks since 4 September 2026 it answered 10. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by structupath.ai and served from www.structupath.ai, the vendor's own domain: https://www.structupath.ai/api/mcp.
14, as returned by the server's own tools/list on 8 September 2026: steel_bolt_pretension, steel_coating_area, steel_connection_reference, steel_gauge_thickness, steel_mtr_check, steel_ncr_generate, steel_pdf_markup, steel_pipe_schedule, and 6 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://www.structupath.ai/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 31 August 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
