## 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**: 89/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
  - The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 60/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 746 tokens (~186/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**: 3/100
  - Stability observed for 1 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% 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 (4)

### `list_datasets` (~147 tokens)

List available Taiwan-market datasets (discovery entry point). Returns id / 中文名 /
    category / tier / one-line description for each. Use this first to find the right data.

    Args:
        category: optional, e.g. 'chip'(籌碼) 'fundamental'(基本面) 'price'(行情) 'macro'(總經)
                  'relation'(關聯/產業鏈) 'derivatives'(期權) 'event'(事件) 'rag_text'(文本).
        tier: optional minimum plan: 'free' 'starter' 'pro' 'max' 'developer' 'enterprise'.

Input parameters:

- `category`
- `tier`

Output parameters:

- `count`
- `datasets`

### `describe_dataset` (~85 tokens)

FULL semantics of one dataset: grain (what a row is), field meanings+units, ★TIME-CORRECTNESS
    rules (knowledge_time_field / point_in_time_safe — read before backtesting), relations for
    cross-table reasoning, agent_hints (when to use), quant_use (which factors). Args: dataset_id.

Input parameters:

- `dataset_id` (string, required)

Output parameters:

- `adjustments`
- `agent_hints`
- `category`
- `coverage`
- `error`
- `grain`
- `hint`
- `id`
- `key_fields`
- `name_zh`
- `quant_use`
- `relations`
- `temporal`
- `tier`

### `query_dataset` (~253 tokens)

Query rows with built-in look-ahead protection.

    ★ POINT-IN-TIME: pass `as_of` (YYYY-MM-DD) for backtesting/agent-learning. For non-point-in-time-safe
    datasets (fundamentals, monthly_revenue, dividend_policy…) rows are filtered by DISCLOSURE date <= as_of,
    so the agent only sees what was public at that moment. Omit as_of only for present-day lookups (warned).

    Args:
        dataset_id: see list_datasets. tickers: e.g. ['2330','2317']. start/end: 'YYYY-MM-DD' range.
        as_of: knowledge-time cutoff 'YYYY-MM-DD' (use for backtests). limit: <=5000.
    Returns: {meta:{table,coverage,row_count,as_of_applied,point_in_time_safe,warnings}, data:[...]}
    Example: query_dataset('fundamental_income', tickers=['2330'], as_of='2023-06-30')

Input parameters:

- `as_of`
- `dataset_id` (string, required)
- `end`
- `limit` (integer)
- `start`
- `tickers`

Output parameters:

- `blocked`
- `data`
- `error`
- `hint`
- `message`
- `meta`
- `status`

### `find_related` (~98 tokens)

Traverse the knowledge graph for cross-table / supply-chain reasoning.
    - dataset_id: returns join-able datasets (+why) to plan multi-table analysis.
    - ticker: returns its industry value-chain node + peers in the same node (supply-chain reasoning).
    Args: dataset_id (e.g. 'equity_daily_prices') and/or ticker (e.g. '2330').

Input parameters:

- `dataset_id`
- `ticker`

Output parameters:

- `chain_error`
- `dataset_relations`
- `error`
- `note`
- `peers_in_node`
- `ticker`
- `value_chain_nodes`
