Available components
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 Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 1 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS enforcement could not be verified: the plaintext port answered with HTTP 404, which proves neither a plaintext path nor enforcement. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability66
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 400 tokens (~400/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- 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 Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 1 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 1 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities20
- Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28. See how to fix → Fail
How do I install the Australian Heat Pump Hot Water Rebate & Payback MCP server?
Australian Heat Pump Hot Water Rebate & Payback is a hosted endpoint at https://heatpump.sourcemill.ai/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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.

check_hot_water_switch ~400
Use when someone asks whether a heat pump hot water system is worth it in Australia, which rebates they can stack, how much a heat pump costs after rebates, or how long it takes to pay off — including "can I combine the STC rebate with Victorian Energy Upgrades or Solar Victoria", "do I qualify", and "is a heat pump cheaper to run than gas". Given a postcode, the current hot water system and a few household facts, returns the rebates actually stackable at that postcode (with each scheme's eligibility gates and source), the net-of-rebate outlay, the payback period, and which term — rebates, the avoidable gas supply charge, the energy saving, or a replacement you were buying anyway — is really carrying the decision. Modelled estimate, not financial advice.
| Name | Type | Req | Description |
|---|---|---|---|
| building_age_years | number | – | age of the building; Victorian Energy Upgrades requires at least 2 years |
| current_system | string | yes | what you have now |
| gas_only_for_hot_water | boolean | – | true if hot water is your last gas appliance, so the daily supply charge can be avoided |
| household_income | number | – | combined owner taxable income, for means-tested schemes (Solar Victoria caps at $150,000) |
| locally_made | boolean | – | an eligible locally made unit, which raises the Victorian caps |
| owner_occupier | boolean | – | tenure — gates the means-tested state rebates |
| people | number | – | household size (drives hot water demand) |
| postcode | string | yes | AU postcode — rebate eligibility is postcode-gated |
| property_value | number | – | property value — Solar Victoria requires under $3,000,000 |
| replacement_due | boolean | – | true if the existing system is failing and you were replacing it anyway |
| system_age_years | number | – | age of the system being replaced; Solar Victoria requires at least 3 years |
