## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 78/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 2506 tokens (~278/item across 9 items; 7 tools + 2 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

Returns topic numbers, titles, one-line summaries and UNVERIFIED counts. Call this first if you are unsure which topic covers a question. Responses keep the KB's confidence tags: [V] verified, [V-mfr] manufacturer claim, [UNVERIFIED], [inference], [Expert] field experience.

Input parameters:

- `include_sections` (boolean): Also list every section id (e.g. 30.4) per topic. Default false.

Output parameters:

- `disclaimer` (string): Reference-only disclaimer that applies to every answer.
- `notes` (array): Notices: renamed/discontinued products, hints, flags. May be empty.

Use after list_topics or search_glazing_knowledge when you need the complete context (e.g. a whole code table). `topic` accepts a number (30), 'T30', 'Topic 30', or a title phrase ('butt glazed'); `section` accepts a section id like '30.4', 'sources', 'key', or a heading phrase like 'summary table' or 'bid-day checklist'. Long topics are paged: follow the continue_from hint. Responses keep the KB's confidence tags: [V] verified, [V-mfr] manufacturer claim, [UNVERIFIED], [inference], [Expert] field experience.

Input parameters:

- `continue_from` (string): Section id to resume paging a long topic from (given in the previous response).

Best for free-text questions: code requirements ('IBC 2406 hazardous locations', 'IECC 2021 zone 2 SHGC'), sizing rules ('max size 1/2 tempered butt glazed', 'shower door hinge clamp rating'), definitions ('LSG', 'heat soak'), estimating red flags, lead-time drivers, testing standards. Use specific technical keywords. For numeric glass makeup data use lookup_glass_performance; for product equivalents use cross_reference_glass / cross_reference_aluminum_system; for budget $ use budget_price_range.

Equivalent does not mean identical: always check depth, plane, glass thickness, thermal tier, performance. Responses keep the KB's confidence tags: [V] verified, [V-mfr] manufacturer claim, [UNVERIFIED], [inference], [Expert] field experience.

## Common questions

### What is the GlaziersEdge Knowledge MCP server?

GlaziersEdge Knowledge is an MCP server listed in the public MCP registry as io.github.shanethelion/glazing-mcp. Commercial glass & glazing reference for AI agents: code limits, glass data, product equivalents. This page covers its hosted endpoint (https://glazing-mcp.glazingkb.workers.dev/mcp).

### Is the GlaziersEdge Knowledge MCP server safe to use?

GlaziersEdge Knowledge scores 81 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the GlaziersEdge Knowledge MCP server expose?

GlaziersEdge Knowledge exposes 7 tools: list_topics, get_topic, search_glazing_knowledge, lookup_glass_performance, cross_reference_glass, and 2 more. Their descriptions and schemas cost roughly 2,328 tokens of context every time the server is loaded.

### Does the GlaziersEdge Knowledge MCP server require authentication?

No. We connected to GlaziersEdge Knowledge without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the GlaziersEdge Knowledge MCP server still maintained?

GlaziersEdge Knowledge is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the GlaziersEdge Knowledge MCP server?

VerifyMCP ran 12 checks on GlaziersEdge Knowledge, covering TLS certificate, Authorization, HSTS header, DNSSEC and 8 more. One item could not be completed, a gap on our side rather than a finding about GlaziersEdge Knowledge: HTTPS. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
