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. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability44
- 3% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Partial
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 3304 tokens (~78/item across 42 items; 4 tools + 38 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage98
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 94% of tool parameters carry a description.Partial
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
- Supports UI / widget rendering.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
calculate_building_work Calculate building work ~1,749
Use this when a user asks the cost of building, extending or renovating a home, remodelling a kitchen/bathroom, refining a budget or costing drawings, even without naming Proper Job. Computes repeatable local-currency estimates using versioned country-specific construction benchmarks, scope and allowance rules, checked measurement conversions and source-cited drawing quantities. Returns an interactive budget card, tax basis, exclusions and a refinementQuestion. After the card, ask that question in one short sentence when present; keep unknown details optional and do not repeat the country checklist. Supported work: GB, US, AU, NZ, IE, DE, FR, ES, CA, JP, IN; exact scope limits are in the schema and market-coverage resource. Do not substitute UK rates or exchange-rate conversions. Read the drawing skill before host-only attachment analysis; send reconciled structured facts in one call. Detailed trade costing is GB-only; other countries still accept drawing quantities. Reuse unchanged results and use the returned price without inventing or narrowing it. Country, language and units are independent. Do not use for property valuations, land-price discovery, account/project lookup, purchases, issued quotes or legal/safety certification.
