## 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**: 89/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 69/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 527 tokens (~87/item across 6 items; 6 tools + 0 resources), lean.
  - 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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Common questions

### What is the Home Repairs Estimator — Cost Calculators MCP server?

Home Repairs Estimator — Cost Calculators is an MCP server listed in the public MCP registry as io.github.helphub369/hsa-cost-calculators. Deterministic cost calculators for HVAC, roofing, plumbing, electrical, solar, water heater. This page covers its hosted endpoint (https://homerepairsestimator.com/mcp).

### Is the Home Repairs Estimator — Cost Calculators MCP server safe to use?

Home Repairs Estimator — Cost Calculators scores 90 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 Home Repairs Estimator — Cost Calculators MCP server expose?

Home Repairs Estimator — Cost Calculators exposes 6 tools: hvac-cost-calculator, roofing-cost-calculator, plumbing-cost-calculator, electrical-cost-calculator, solar-cost-calculator, water-heater-cost-calculator. Their descriptions and schemas cost roughly 527 tokens of context every time the server is loaded.

### Does the Home Repairs Estimator — Cost Calculators MCP server require authentication?

Yes. Home Repairs Estimator — Cost Calculators asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

### Is the Home Repairs Estimator — Cost Calculators MCP server still maintained?

Home Repairs Estimator — Cost Calculators 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 Home Repairs Estimator — Cost Calculators MCP server?

VerifyMCP ran 13 checks on Home Repairs Estimator — Cost Calculators, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. 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.
