## Changes things (13)

Creates or changes something that can be changed back. Claude Code: ask.

### `buffett_scan`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Rank US public companies by Quality Score (0-100) over a 10-year
window from five components: return on invested capital (30 points,
blended 60/40 with the company's industry percentile), durability
through the cycle (20), cash conversion (20), balance-sheet strength (15)
and capital discipline (15). Every component is explainable from the
returned row (roic_median, fcf_conversion, net_debt_to_ebit, ...); a
component with no usable data is dropped and the rest renormalized.
Companies that stopped filing (4,313), have fewer than five fiscal years
on file (1,702), lack the tags to measure returns on capital in enough of
those years -- missing EBIT tags, or an unclassified balance sheet,
common among homebuilders and industrials with captive finance arms
(1,612) -- or are balance-sheet financials (banks, insurers, REITs;
1,539) are not scored and do not appear: 2,885 of 12,051 companies
(roughly a quarter of all filers, ~37% of active ones) are scored today.
Use it for price-independent quality; use buffett_value to add
valuation. Methodology v3; heuristic screen, not investment advice.
Cost: $0.25 per call; unpaid calls return a payment-required error.
```

### `company_facts`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Raw normalized XBRL facts for one company as reported in its SEC
filings, newest first: concept, value, unit, period_start and period_end,
fiscal_year, fiscal_period, form, filed date and data-quality flags. Use
it for individual reported values, quarterly figures or filing
provenance; use company_financials for clean annual statements and
ratios. Cost: $0.01 per call; unpaid calls return a payment-required error.
```

### `company_filings`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
SEC filing index for one company, newest first: form, filing date,
report period, accession number, 8-K item codes and a direct sec.gov
document_url. Use it to find or cite a specific 10-K, 10-Q, 8-K or Form 4;
use company_facts or company_financials for the numbers in the filings.
Cost: $0.005 per call; unpaid calls return a payment-required error.
```

### `company_financials`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Annual financial statements for one company, one row per fiscal year:
income statement, balance sheet and cash flow lines plus ratios
(gross_margin, operating_margin, roe, roa, fcf, debt_to_equity, ...).
Use it for a known company's history; use company_facts for individual
reported values and quarterly periods, compare_to_peers to benchmark it
against its industry, and screen_companies to find companies by criteria.
Cost: $0.02 per call; unpaid calls return a payment-required error.
```

### `company_signal`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Composite factor scorecard for one company: quality (Piotroski,
Altman, accruals), value (owner-earnings DCF), insider conviction (Form 4
buying as bps of market cap), institutional positioning (13F) and short
sentiment, each 0-100, plus a renormalized composite_score and coverage
(the share of factors present). Also returns institutional ownership %,
insider buy intensity, short-to-ADV and governance flags (Form 4 latency,
Item 4.02 restatements, stale fundamentals). Use top_signals to rank
every company by the same composite. RESEARCH SIGNAL, NOT INVESTMENT
ADVICE. Cost: $0.05 per call; unpaid calls return a payment-required error.
```

### `industry_aggregate`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Benchmark percentiles (p10, p25, median, p75, p90, plus mean and
company count n) for one financial metric, per fiscal year, 2-digit SIC
industry group and revenue size bucket. Use it for questions like "what
is the median gross margin of large software companies?"; use
compare_to_peers to place one company in its cohort and market_insight
(sector_landscape) for margin medians across every industry.
Cost: $0.05 per call; unpaid calls return a payment-required error.
```

### `insider_activity`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Insider (Form 4) transactions for one company over the trailing
months, plus a summary: open-market buys vs sales, distinct buyers and
net dollar value, with 10b5-1 plan flags. Cluster buying by officers and
directors is a studied positive signal. Use company_signal for insider
conviction scored alongside other factors. Not investment advice.
Cost: $0.02 per call; unpaid calls return a payment-required error.
```

### `institutional_ownership`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
13F institutional ownership snapshot for one company: number of
holders, aggregate shares and value, and quarter-over-quarter change
(accumulating vs trimming). 13F filings lag the quarter by up to 45 days
and show long positions only. Use company_signal for institutional
positioning scored alongside other factors. Not investment advice.
Cost: $0.02 per call; unpaid calls return a payment-required error.
```

### `market_insight`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Curated analysis computed live across all US public companies, chosen
by name: top_companies (rank by a metric, optionally within an
industry), movers (largest change in a metric between fy_from and fy_to),
sector_landscape (margin medians per industry), metric_trend (yearly sum,
median or mean of a metric), capital_returns (buybacks vs dividends by
size bucket) or filing_velocity (monthly filing counts for a form type).
Each parameter's description says which analyses read it; the response
reports the fiscal year(s) used. Use screen_companies for your own
criteria and standard_score for F-Score, Z-Score and similar scores.
Cost: $0.15 per call; unpaid calls return a payment-required error.
```

### `screen_companies`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Screen US public companies for one fiscal year by financial criteria
and return the matches with their name, tickers, industry and metrics,
largest revenue first. Use it to discover companies; use
company_financials for one known company's history and
industry_aggregate for cohort benchmarks.
Cost: $0.10 per call; unpaid calls return a payment-required error.
```

### `short_pressure`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Short-selling pressure for one company: the FINRA daily short-volume
ratio (short volume / total volume) over about 20 trading days, a
bearish-sentiment proxy. This is daily short-sale volume, not bi-monthly
short interest. Use company_signal for short sentiment scored alongside
other factors. Not investment advice.
Cost: $0.02 per call; unpaid calls return a payment-required error.
```

### `standard_score`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Academic fundamental scores across US public companies, chosen by
name: piotroski (F-Score 0-9, financial strength), altman_z
(bankruptcy-risk zones), beneish_m (elevated M-Score: an
accounting-quality screen, not evidence of manipulation), magic_formula
(Greenblatt rank on earnings yield and return on capital) or accruals
(Sloan earnings quality). Each company is scored on its own latest fiscal
year (fiscal_year per row); fy selects the cohort whose latest scored
year is fy -- it does not re-score companies on an earlier year. Use
company_signal for one company's quality, value and sentiment factors
together. Peer-reviewed formulas; not investment advice.
Cost: $0.15 per call; unpaid calls return a payment-required error.
```

### `top_signals`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Rank US public companies by composite factor score (quality, value,
insider, institutional and short-sentiment factors, each 0-100), highest
first, with each company's factor scores, coverage, and restatement and
stale-fundamentals flags. Use company_signal for one company's full
scorecard. RESEARCH SIGNAL, NOT INVESTMENT ADVICE.
Cost: $0.25 per call; unpaid calls return a payment-required error.
```

## Only reads (4)

Looks things up and changes nothing. Claude Code: allow.

### `buffett_value`

- The description's first verb is "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find high-quality US public companies trading below intrinsic value:
the Quality Score (see buffett_scan) combined with a value score from the
previous close (FCF yield, 10-year owner-earnings DCF margin of safety,
P/E), ranked by combined_score, the mean of the two (0-100 each). Rows
also carry market cap, owner-earnings yield and intrinsic value. Use
buffett_scan for quality alone; it needs no price data. Foreign private
issuers (20-F filers, e.g. Chinese ADRs) are excluded by default: they
screen cheap for structural reasons fundamentals cannot see. Methodology
v3; heuristic screen, not investment advice.
Cost: $0.25 per call; unpaid calls return a payment-required error.
```

### `compare_to_peers`

- The name "compare_to_peers" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
One company's metrics for a fiscal year next to its industry cohort:
the percentiles of every metric for each revenue size bucket in its
2-digit SIC group. Use it to judge whether a company's margins, returns
or leverage are above or below sector norms; use industry_aggregate for
a cohort without a specific company.
Cost: $0.05 per call; unpaid calls return a payment-required error.
```

### `list_insights`

- The name "list_insights" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Catalog of the curated market-wide analyses: each one's name, path,
description, parameters with defaults, and price. Call it before
market_insight or standard_score to choose an analysis and its
parameters. Free: no API key or payment needed.
```

### `lookup_company`

- The name "lookup_company" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find a company's SEC CIK from its ticker, CIK or name. Every company
tool takes a cik, so call this first when you only have a ticker (AAPL)
or a name (apple). Returns up to limit matches, best first (exact ticker,
exact CIK, name prefix, name contains; within each, companies with
tickers before other filers such as individuals), each with cik, name,
tickers, sic and sic_description; no match is an empty list, not an
error. Free: no API key or payment needed.
```
