GlaziersEdge Knowledge

GlaziersEdge Knowledge

GlaziersEdge Knowledge is a free, hosted Model Context Protocol server that gives AI agents a curated reference for US commercial glass and glazing: architectural glass makeups and performance data, coated-glass and aluminum-framing "or equal" cross-references, safety-glazing, energy, impact and fire code limits, and early-stage budget ranges. Every answer is cited to a topic and section and keeps a confidence tag, so you can see how solid each item is.

This repository holds listing and connection information only. The server itself is hosted; there is nothing to install.

What it covers

• Glass: annealed, heat-strengthened, tempered, laminated, insulating glass, low-E and reflective coatings, spandrel, low-iron, heat soak, glass performance terms (VLT, SHGC, U-factor, LSG).
• Glass performance data: 227 one-inch insulating-glass makeups from Vitro, Guardian SunGuard and Viracon, filterable by maker, product, substrate, SHGC, VLT, U-value and LSG. Old product names are mapped to current ones.
• Equivalents: coated-glass equivalents across makers with a match rating (Close / Approximate / Not supported by the numbers), and storefront, curtain wall, entrance and window series equivalents across major aluminum framing manufacturers, with discontinued and renamed notices.
• Codes and standards: safety glazing (IBC 2406), energy (IECC, ASHRAE 90.1, Title 24), hurricane/impact, fire-rated glazing, wind load (ASTM E1300), railings and guards, testing standards.
• Systems and practice: storefront, curtain wall, all-glass/butt-glazed walls and doors, structural silicone, sealants, specs, submittals, warranties, lead times, estimating red flags.
• Budget ranges: experienced-estimator 2026 US installed budget ranges for early estimating and sanity checks. Never for bids.

32 topics in all, US national coverage.

Confidence tags

Answers keep the knowledge base's tags. Agents are asked to pass them on to you.

Tools

All tools are read-only and idempotent (readOnlyHint: true, destructiveHint: false).

Prompts: glazing_question (answer a glazing question with citations) and or_equal_substitution (find equivalents for a specified glass coating or framing series). Resources: glaziersedge://topics (topic index) and glaziersedge://disclaimer (confidence tags and disclaimer). Server card: https://glazing-mcp.glazingkb.workers.dev/.well-known/mcp/server-card.json

Structured output: every tool declares an outputSchema and returns matching structuredContent (JSON records with the same data and tags), alongside the markdown text answer.

Optional config: none is required. Add ?detail_level=brief to the endpoint URL to drop the repeated confidence-tag legend from text answers (the tags on each item stay). Schema: https://glazing-mcp.glazingkb.workers.dev/.well-known/mcp-config Glass values are center-of-glass, not NFRC whole-product ratings.

Example prompts

• "What's the Vitro equivalent of Guardian SunGuard SNX 62/27?"
• "Kawneer Trifab 451: what are the equals from other manufacturers?"
• "Max size for 1/2 in. tempered butt-glazed glass?"
• "IECC 2021 climate zone 2 fenestration SHGC and U-factor limits?"
• "List 1-inch IGUs with SHGC at or below 0.25 and VLT of at least 50%, sorted by LSG."
• "Which glazing locations does IBC 2406 treat as hazardous?"
• "Budget range per SF for exterior storefront?"

Pricing

Free during launch. Per-request agent payments (pay-per-call over the x402 protocol, so agents can pay without an account) are planned for some tools later. Topic browsing will stay free, and any change will be announced here before it takes effect.

Privacy and usage logging

Usage is logged anonymously to improve coverage: timestamp, tool name, a redacted and truncated query (emails, phone numbers and long digit strings are masked), result count, latency, MCP client name/version, a coarse user-agent family, and country. No IP addresses, cookies, tokens or personal data are stored. Logs are deleted after 180 days. Don't put confidential project information in queries.

Disclaimer

This service provides general reference information for commercial glazing professionals. It is not engineering, legal, or code-compliance advice, and it is not a substitute for manufacturer data, the code adopted by your jurisdiction, project specifications, or review by a licensed professional. Items tagged [UNVERIFIED] or [inference] need confirmation. Budget ranges are [Expert] estimates that vary by region, scope and market, and must never be used for bids. Equivalents are screening aids: "equivalent" does not mean identical, so check depth, glazing plane, glass thickness, thermal and structural performance before substituting. Information may be out of date; product lines change.
