## 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 2026-10-02.

- **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**: 76/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 656 tokens (~93/item across 7 items; 7 tools + 0 resources), lean.
  - 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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (7)

### `search_stocks` (~96 tokens)

Search stocks

Find a company in Talval's coverage by name or ticker. Typo tolerant. Use this first when you only have a company name.

Input parameters:

- `limit` (integer): How many matches to return. Raise it when a name is ambiguous across listings — Shell and Unilever trade in more than one place.
- `query` (string, required): Company name or ticker, e.g. 'Rheinmetall' or 'RHM.DE'.

Output parameters:

- `matches` (array): Empty when nothing in Talval's coverage matches.
- `query` (string)

### `get_stock_research` (~74 tokens)

Get stock research

Talval's valuation verdict, fair-value estimate, upside, quality/safety/value scores and latest filed results for one ticker. End-of-day snapshot with a date.

Input parameters:

- `ticker` (string, required): Exact ticker as Talval lists it, e.g. 'AAPL', 'RHM.DE', 'PRU.L'.

Output parameters:

- `as_of` (string|null): Date of the verdict snapshot, YYYY-MM-DD.
- `conviction` (integer|null): 1-10.
- `country` (string|null)
- `covered` (boolean): False when Talval does not cover this ticker; every other field is then null.
- `currency` (string|null): Trading currency of price and fair value.
- `dividend_yield_pct` (number|null): Forward yield as a PERCENT, e.g. 2.9 for 2.9%.
- `fair_value` (number|null): Null when withheld — see fair_value_usable and withheld_reason.
- `fair_value_usable` (boolean): False when the company reports in a different currency than it trades in, which makes every price-to-fundamentals figure cross-currency nonsense. A false here is a deliberate suppression, not missing…
- `industry` (string|null)
- `latest_annual` (object|null): As reported in the company's own filings — not estimates.
- `market_cap` (number|null)
- `name` (string|null)

- `price` (number|null)
- `price_as_of` (string|null)

- `sector` (string|null)
- `ticker` (string)
- `upside_pct` (number|null): Percent, not a fraction.
- `url` (string|null)
- `verdict` (string|null): Undervalued, Fairly valued or Overvalued.
- `withheld_reason` (string|null): Why fair_value is null, when it is.

### `screen_stocks` (~93 tokens)

Screen stocks

Run one of Talval's stock screens over the covered universe and return the ranked results with fair value, upside and scores.

Input parameters:

- `limit` (integer): How many ranked rows to return. The screen is already ranked, so a smaller number gives the strongest names rather than a sample.
- `screen` (string, required): Which screen to run.
- `sector` (string): Optional sector filter, e.g. 'Technology'.

Output parameters:

- `label` (string|null)
- `rows` (array): Ranked. Empty when nothing clears the screen.
- `screen` (string)
- `sector` (string|null): The sector filter applied, if any.

### `compare_stocks` (~40 tokens)

Compare stocks

Put two or more tickers side by side on verdict, fair value, upside and scores.

Input parameters:

- `tickers` (array, required): Tickers to compare.

Output parameters:

- `companies` (array)
- `not_covered` (array): Tickers asked for that Talval does not cover.

### `list_superinvestors` (~32 tokens)

List superinvestors

The investors Talval tracks through their quarterly 13F filings — portfolio size, position count and largest holdings.

Output parameters:

- `investors` (array)

### `get_superinvestor` (~50 tokens)

Get a superinvestor's portfolio

One tracked investor's reported holdings and quarter-on-quarter activity. Call list_superinvestors first to get the slug.

Output parameters:

- `note` (string|null): This week's written note, when there is one.
- `picks` (array): Empty when nothing is published for this week yet.
- `week_start` (string|null)
