## 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 2026-08-03.

- **Endpoint Security**: 80/100
  - 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.
  - 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**: 66/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 886 tokens (~98/item across 9 items; 9 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 88/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 57% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (9)

### `estimate_agent_usage` (~210 tokens)

Estimate MockHero agent-plan cost before generating data. No login or API key is required; include an API key only when you want the estimate to use actual daily usage.

Input parameters:

- `api_key` (string): Optional MockHero API key for no-auth MCP clients. Prefer the Authorization header when the client supports it.
- `daily_used_before` (integer): Optional assumption when no API key is supplied.
- `estimated_records` (integer): Required for prompt estimates because this tool does not run prompt-to-schema conversion.
- `format` (string)
- `locale` (string): Default locale such as en, de, fr, es, or ja.
- `prompt` (string): Plain-English data request. Example: 50 users and 200 orders linked to them.
- `scale` (number): Multiplier for template record counts.
- `seed` (number): Seed for reproducible output.
- `sql_dialect` (string)
- `tables` (array)
- `template` (string)

### `create_agent_checkout` (~101 tokens)

Create a loginless Polar Checkout URL for MockHero's metered agent plan. Polar is the Merchant of Record for checkout, tax collection, and remittance. The card payment step needs a human: present the returned url to your operator together with the estimate_agent_usage cost, keep the claim_token private, then poll check_agent_checkout_status and call claim_agent_api_key once paid.

Input parameters:

- `email` (string, required): Billing email for the agent or the agent operator.

### `check_agent_checkout_status` (~39 tokens)

Poll a Polar checkout created by create_agent_checkout using the returned claim_token.

Input parameters:

- `token` (string, required): claim_token returned by create_agent_checkout.

### `claim_agent_api_key` (~47 tokens)

Claim the MockHero API key after Polar marks the loginless agent checkout as paid. The key is returned once.

Input parameters:

- `token` (string, required): claim_token returned by create_agent_checkout.

### `generate_test_data` (~172 tokens)

Generate realistic JSON, CSV, or SQL test data from structured tables or a plain-English prompt. Explicit table schemas up to 100 records can run free as a proof-of-work preview; plain-English prompt generation, larger requests, and production usage require a MockHero API key.

Input parameters:

- `api_key` (string): Optional MockHero API key for no-auth MCP clients. Prefer the Authorization header when the client supports it.
- `format` (string)
- `locale` (string): Default locale such as en, de, fr, es, or ja.
- `prompt` (string): Plain-English data request. Example: 50 users and 200 orders linked to them.
- `seed` (number): Seed for reproducible output.
- `sql_dialect` (string)
- `tables` (array)

### `generate_from_template` (~126 tokens)

Generate realistic test data from a pre-built MockHero template: ecommerce, blog, saas, or social. Small template previews up to 100 records can run free; larger or production usage requires a MockHero API key.

Input parameters:

- `api_key` (string): Optional MockHero API key for no-auth MCP clients. Prefer the Authorization header when the client supports it.
- `format` (string)
- `locale` (string)
- `scale` (number)
- `seed` (number)
- `sql_dialect` (string)
- `template` (string, required)

### `detect_schema` (~61 tokens)

Convert SQL CREATE TABLE statements or one sample JSON object into a MockHero schema that can be passed to generate_test_data.

Input parameters:

- `sample_json` (object): Single example JSON object to infer fields from.
- `sql` (string): SQL CREATE TABLE statement or statements.

### `list_field_types` (~26 tokens)

List MockHero field types, descriptions, parameters, and examples before building a schema.

### `list_templates` (~28 tokens)

List MockHero's pre-built schema templates for ecommerce, blog, SaaS, and social apps.
