## 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**: 77/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 67/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1789 tokens (~178/item across 10 items; 10 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 63/100
  - Stability observed for 19 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 10 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 11 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).

## MCP tools (10)

### `scrape_business` (~152 tokens)

Scrape a business website

Given a business website domain, returns the business name and the page element it came from, the published contact surface, and the technology platforms the site runs (analytics, tag managers, email marketing, SEO tools and more), each with the evidence it was detected from. Every claim is checked against its evidence and unsupported ones are struck on Agent Harbor's own hardware. Faster, cheaper tier than /enrich. Not charged if the page cannot be used. Free prompt-injection scan included. Costs $0.01 USDC per successful call (x402, eip155:8453); failures are not charged.

Input parameters:

- `domain` (string, required): Bare domain, no scheme or path, e.g. mailchimp.com

### `enrich_business` (~130 tokens)

Enrich a company profile

Given a company domain, returns a validated company profile: business name, firmographics (for example service area and team size) and a technology-stack summary, written by a model on Agent Harbor's own hardware and checked claim by claim against the scraped page evidence; unsupported claims are struck and provenance is included. No input reaches a third-party AI provider. Not charged on failure. Costs $0.05 USDC per successful call (x402, eip155:8453); failures are not charged.

Input parameters:

- `domain` (string, required): Bare domain, no scheme or path, e.g. mailchimp.com

Same scrape and evidence check as /scrape, without the evidence detail, at half the price. Free prompt-injection scan included. Not charged if the page cannot be used or no business name is found. Costs $0.005 USDC per successful call (x402, eip155:8453); failures are not charged.

Static check, no browser. Not charged if robots.txt cannot be read (no response, or a bot block). Costs $0.01 USDC per successful call (x402, eip155:8453); failures are not charged.

Input parameters:

- `domain` (string, required): Bare domain, no scheme or path, e.g. mailchimp.com

### `site_audit` (~148 tokens)

Website tracking, consent and SEO audit

Given a business website domain, audits its home page in a real browser and returns a ranked fix list with evidence: analytics and tag-manager tags, the consent manager and whether tracking loads before a consent choice, structured data (schema.org), AI-crawler access (robots.txt, llms.txt) and SEO basics. Findings that depend on what a visitor sees are marked as leads to verify. Not charged if the page cannot be audited (bot block, error). Costs $0.05 USDC per successful call (x402, eip155:8453); failures are not charged.

Input parameters:

- `domain` (string, required): Bare domain, no scheme or path, e.g. mailchimp.com

### `sec_company` (~220 tokens)

SEC EDGAR company profile

Given a U.S.-listed company's stock ticker or SEC CIK, returns its EDGAR profile (legal name, tickers, exchanges, SIC industry, state of incorporation, fiscal year end), its latest annual financials from XBRL (revenue, operating and net income, diluted EPS, assets, liabilities, equity, cash, shares outstanding, each with period and source filing) and its recent filings with 8-K item titles and document links.

An empty result is an answer. Not charged if a source is down. Costs $0.005 USDC per successful call (x402, eip155:8453); failures are not charged.

Domain verification

Given a domain, tells whether it is a real, live and established business domain: DNS (A, MX, NS, SPF, DMARC, DNSSEC), registration from RDAP (registrar, created and expiry dates, age, status; never registrant contacts), the TLS certificate (valid, issuer, expiry) and the website (final URL, status, HSTS), with risk flags such as newly registered, no MX or invalid TLS. 'Does not exist' is an answer. Not charged if lookups fail. Costs $0.005 USDC per successful call (x402, eip155:8453); failures are not charged.
