- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 93 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 9 of 9 tools declare readOnlyHint or destructiveHint
- warn `tools.directory_hints`: 4 of 9 tools declare all four hints; missing: estimate_agent_usage (idempotentHint); check_agent_checkout_status (idempotentHint); detect_schema (idempotentHint); …
- pass `tools.token_cost`: about 1,690 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history not recorded yet

### dependencies: 50 (weight 15)

- warn `deps.known_vulns`: 1 advisory of lower severity or without a published fix: GHSA-5r4p-p66f-jhc7 in hono@4.13.9 (indirect, fixed in 4.13.11)
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.30.1 has 3 known advisories (GHSA-22jm-h49p-29qw, GHSA-6prh-2h8m-c8cw, GHSA-6qxp-vccf-f47h); update @modelcontextprotocol/sdk to 1.32.0 or later
- pass `deps.resolvable`: @mockherodev/mcp-server@0.2.0 resolved: 98 packages

- tools: 9, about 1,690 tokens to load them all
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.dinosaur24/mockhero.svg)](https://protogrid.dev/servers/io.github.dinosaur24/mockhero)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Remotes

- https://mockhero.dev/mcp/agent (streamable-http, auth none, reachable false, uptime30d 0.071428575)

## Packages

- npm @mockherodev/mcp-server@0.2.0 secrets: MOCKHERO_API_KEY

## Tools (9)

- `check_agent_checkout_status`: Poll a Polar checkout created by create_agent_checkout using the returned claim_token.
- `claim_agent_api_key`: Claim the MockHero API key after Polar marks the loginless agent checkout as paid. The key is returned once.
- `create_agent_checkout`: 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.
- `detect_schema`: Convert SQL CREATE TABLE statements or one sample JSON object into a MockHero schema that can be passed to generate_test_data.
- `estimate_agent_usage`: 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.
- `generate_from_template`: 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.
- `generate_test_data`: 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.
- `list_field_types`: List MockHero field types, descriptions, parameters, and examples before building a schema.
- `list_templates`: List MockHero's pre-built schema templates for ecommerce, blog, SaaS, and social apps.
