## 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.
  - Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - 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**: 77/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 510 tokens (~127/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 17/100
  - Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 40/100
  - Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28.

## MCP tools (4)

### `business_info` (~58 tokens)

Get the facts about Joey George Plumbing: an owner-operator residential plumbing business in South Orange County, CA. Returns services, the 13-city service area, hours (24/7), and the website. Website is the only contact channel returned.

### `check_water_hardness` (~131 tokens)

Look up tap-water hardness for a South Orange County city (plus Irvine). Returns the hardness in grains per gallon (gpg), what that level means for a home, and whole-house treatment guidance following Joey's no-drain-line rule (HALO 5 is the default pick in hard-water cities; H2 Zero Scale Media is an option in moderate San Clemente). Cities not in the dataset get an honest general area range, never an invented number.

Input parameters:

- `city` (string, required): City name, e.g. 'Laguna Niguel', 'Mission Viejo', 'San Clemente'.

### `water_heater_check` (~129 tokens)

Get maintenance and troubleshooting guidance for a tank water heater based on its age and (optionally) symptoms such as popping/rumbling noises, running out of hot water, leaking, rusty water, or no hot water. General guidance, not a diagnosis or a quote. The $99 everyday flush price is mentioned only when sediment/flush guidance applies.

Input parameters:

- `age_years` (number, required): Age of the water heater in years (from the manufacture date on its label).
- `symptoms` (string): Optional description of symptoms, e.g. 'popping noises and running out of hot water'.

### `plumbing_question` (~113 tokens)

Ask a common homeowner plumbing question and get a short, plain-language, teach-first answer. Covered topics: running toilet / flapper dye test, finding the main shutoff and the 3 shutoffs, water meter leak check, gurgling drains, high water pressure signs and PRV, sediment / popping water heater, rotten-egg hot water smell, garbage disposal dos and don'ts. Off-topic questions get an honest list of what is covered.

Input parameters:

- `question` (string, required): The homeowner's question in plain words.

### Does the Joey George Plumbing MCP server require authentication?

### Is the Joey George Plumbing MCP server still maintained?

### What did VerifyMCP test on the Joey George Plumbing MCP server?

VerifyMCP ran 12 checks on Joey George Plumbing, covering TLS certificate, HTTPS, HSTS header, DNSSEC and 8 more. One item could not be completed, a gap on our side rather than a finding about Joey George Plumbing: Authorization. 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.
