## 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**: 46/100
  - 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 8 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 not yet verified: we couldn't determine whether a plaintext access path exists.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 64/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1655 tokens (~206/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 20/100
  - Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 91/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 74% of tool parameters carry a description.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 56, +1)

- [security] The server rewrote its instructions, which are the text every model session reads
- [security] Tool “query_records” rewrote its description, which is the text the model reads
- [functional] Schema quality: good → excellent

### 2026-08-02 (score 55, +1)

No change was recorded against any check on this day. Stability & Change Management went from 13 to 17. That category is still filling its 30-day observation window: 4 days of observed history at the previous scan, 5 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-07-31 (score 54, −2)

- [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server

### 2026-07-29 (score 56, +1)

- [functional improvement] Stability: unverified → 0.03

### 2026-07-28 (score 55)

First indexed and scored.

## MCP tools (8)

### `create_project` (~204 tokens)

Create a new mock REST API project. Returns {id, adminKey, baseUrl, resources[]}. SAVE the adminKey — it is required for admin operations (add_resource, custom_route, snapshots) and is shown only once. Presets seed a full multi-resource backend: blog (posts/comments/authors), ecommerce (products/orders/customers/reviews), saas (users/teams/events). Omit preset for a starter project (one seeded "items" resource — live data immediately, reshape or delete it); use "blank" for a truly empty project you fill via add_resource or import_data. The mock API is then live at baseUrl: standard REST CRUD (GET/POST/PUT/PATCH/DELETE), CORS enabled, no auth needed.

Input parameters:

- `name` (string): Project name (max 60 chars). Optional.
- `preset` (string): Seeded preset; 'blank' = truly empty. Omit for a starter project. Optional.

### `import_data` (~180 tokens)

Create a live mock API from existing artifacts. Auto-detects: OpenAPI 3.x / Swagger 2.0 spec (JSON or YAML) → resources with realistic seeded data; json-server db.json → hosts your exact records; Postman Collection v2.x → resources from requests, saved example responses become records verbatim; CSV/TSV → one typed collection (numbers/booleans inferred per column). Max 512 KB. Returns {id, adminKey, baseUrl, warnings[]}.

Input parameters:

- `content` (string, required): The raw spec / db.json / collection / CSV text.
- `name` (string): Project name override. Optional.
- `resource` (string): CSV only: collection name (default items).
- `seed` (number): Records to seed per resource for OpenAPI specs (default 20, max 100).

### `add_resource` (~297 tokens)

Add a resource (collection) to a project and seed it with realistic fake data. Either pass template (one of the built-ins, e.g. users, products, posts, comments, orders, todos, reviews, customers, events) or fields: an array of {name, type} where type ∈ uuid|firstName|lastName|fullName|username|email|avatar|image|word|words|title|sentence|paragraph|number|price|percent|boolean|date|pastDate|futureDate|url|domain|ip|phone|city|country|address|zipCode|company|jobTitle|color|latitude|longitude|rating|age|slug|status|category|refId, plus {name, type:"oneOf", values:[...]} for enums. seed = number of records to generate (default 20, max 100, 0 = empty).

Input parameters:

- `adminKey` (string, required): The project's adminKey.
- `fields` (array): Array of {name, type} (or {name, type:'oneOf', values:[…]}). Optional.
- `name` (string, required): Resource name, plural (e.g. products).
- `project` (string, required): Project id.
- `seed` (number): Records to seed (default 20, max 100).
- `template` (string): Built-in template name. Optional (use this OR fields).

### `project_info` (~80 tokens)

Get a project's public root index: every resource with record counts and URLs, custom routes, auth mode, and export links (openapi.json, types.ts, postman.json, db.json, GraphQL). No adminKey needed. Try project "demo" for the shared public playground.

Input parameters:

- `project` (string, required): Project id (e.g. demo).

### `query_records` (~247 tokens)

GET records from a mock resource. params is an object of query parameters, all optional: exact filters (field=value), operator suffixes (price_gte, date_lte, name_like, status_ne), full-text q, _sort/_order (or _page/_limit for pagination), select (field projection, e.g. "name,price"), _expand=<parent>/_embed=<children> relations. Failure simulation for testing: mock_status=503 forces that status, mock_delay=2000 adds latency (ms), mock_chaos=0.3 fails that fraction of requests randomly, mock_seq=503,503,200 serves a deterministic status sequence (fail twice then succeed — best for retry tests), mock_jitter=500 adds random latency, mock_envelope=data wraps the response. Pass id to fetch a single record. Defaults to _limit=25 — pass _limit explicitly for more (max 100 per page).

Input parameters:

- `id` (string): Single record id. Optional.
- `params` (object): Query params as key→value. Optional.
- `project` (string, required)
- `resource` (string, required): Resource name (e.g. products).

### `write_record` (~107 tokens)

Create, update, or delete records in a mock resource. Writes persist (unlike JSONPlaceholder/FakeStoreAPI). POST creates (auto-id), PUT replaces, PATCH merges, DELETE removes. id required for PUT/PATCH/DELETE.

Input parameters:

- `body` (object): Record fields (POST/PUT/PATCH).
- `id` (string): Record id (PUT/PATCH/DELETE).
- `method` (string, required)
- `project` (string, required)
- `resource` (string, required)

### `custom_route` (~205 tokens)

Define a custom endpoint on a project (like /health, /config/:key, or a catch-all /webhooks/* request bin). body is a response template: {{query.x}} {{params.x}} {{body.x}} {{headers.x}} {{method}} {{path}} {{now}} {{ts}} {{uuid}} {{rand}}; triple braces {{{body}}} insert raw JSON. Custom routes take precedence over resource routes; '*' catch-alls are a fallback. Max 20 routes/project.

Input parameters:

- `adminKey` (string, required)
- `body` (string): Response body template (string; JSON works).
- `contentType` (string): Default application/json.
- `delayMs` (number): Artificial latency in ms.
- `method` (string): Default GET.
- `path` (string, required): e.g. /health, /config/:key, /webhooks/*
- `project` (string, required)
- `status` (number): Response status (default 200).

### `snapshots` (~112 tokens)

Deterministic test fixtures: save the project's entire dataset under a name, restore it exactly later (list/delete too). Any GET can also be served read-only FROM a snapshot without touching live data via query param mock_snapshot=<name> in query_records params — parallel test scenarios on one project.

Input parameters:

- `action` (string, required)
- `adminKey` (string, required)
- `name` (string): Snapshot name (required for restore/delete; default for save: snapshot-<n>).
- `project` (string, required)
