## Findings

- **warn** Annotations that disagree with the tool in `run_sql` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "run_sql" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The name "run_sql" says "run": a word for a change.
```


## Changes things (1)

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

### `run_sql`

- The name "run_sql" says "run": a word for a change.
- The input takes a statement or command to run (input.sql), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
PostgreSQL SELECT over financial / market / alt-data tables — returns structured rows.

Hard rules (query fails otherwise):
- SELECT only, no CTE (`WITH ... AS`) — use subqueries.
- Period columns are TEXT, not dates — `period_end` is 'YYYY-MM'. Compare as strings (`period_end >= '2024-01'`); a `::date` cast on it fails.
- Filter structured tables by ticker (`WHERE ticker IN ('AAPL','MSFT')`; screening: add `ticker NOT LIKE '%-%'` to drop preferred stock).

Tables by domain (get_table_schema gives columns + coverage note):
- Market: price_volume_history (OHLCV history; MUST filter ticker + time_frame), index_price, equity_extended_rt (pre/after/overnight quotes)
- Fundamentals: financial_statements (GAAP income/balance/cashflow), company_snapshot (ratios, per-share, growth)
- Earnings: earning_call_summary, earning_call_calendar
- Analyst: analyst_ratings, analyst_ratings_consensus
- Ownership: insider_and_institution_activities
- 8-K events: executive_change, company_deal_events, debt_issuance, securities_offering
- Executives: executive_profile, executive_compensation
- Alt-data: macro / industry / trade / AI-supply-chain — call list_tables(categories=[...])
```

## Only reads (9)

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

### `ai_adoption`

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

Description, as the server wrote it:

```untrusted-server-text
Search concrete enterprise AI applications disclosed in US company earnings calls. Filter by ticker, partially match a company name, search for an application or workflow by name, or use since in YYYY-MM-DD format to include only observations updated on or after that date. Returns a data array ordered by update_date descending. Each result contains ticker, company_name, application_name, first_report_date, update_date, summary (an AI application summary), evolution_summary, business_position, deployment_stage, deployment_scope, value_type, metrics (application-related metrics), and evidence (supporting management quotes, with speaker and section when available). Use this tool to identify where and how a company applies AI, assess deployment maturity, scope, and disclosed value, and inspect the supporting evidence. Use no filters to browse the most recently updated observations. No matches return an empty data array.
```

### `company_search`

- The name "company_search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use for qualitative company discovery (industry, business model, supply chain, competitors, management background). For numerical screening (revenue, margins, ratios, growth rates) use run_sql on company_snapshot instead.

Drillr's company knowledge graph — searchable across industry classification, product offerings, business model, segment structure, competitive landscape, supply chain, management background, and customer profile.

Coverage: US, Japan, Hong Kong, China A-shares, and Korea. `market` accepts one lowercase value or a list from `us | jp | hk | cn | kr`; omit it or pass `[]` for all five. List order does not set priority.

Pass a natural-language description (for example, "Hong Kong and China EV battery suppliers"). Returns a structured list of matching companies with context snippets.

ONLY for finding a LIST of companies by description.
```

### `filing_list`

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

Description, as the server wrote it:

```untrusted-server-text
Use to discover which SEC filings exist for a ticker before searching content.
For the actual content use filing_search instead.

List indexed SEC filings for a given ticker with a summary header.

Returns: summary (period coverage, per-type counts) + table of up to 50 filings
(fiscal_year, fiscal_quarter, filing_type, filing_date, period_start, period_end).

filing_types filter: omit for main reports only (US 10-K/10-Q/20-F/S-1/DEF 14A
+ /A amendments; JP 120/140/160; A-share annual_report / quarterly_report /
q1_report; excludes ad-hoc 8-K/6-K); pass [] for all indexed types; pass explicit
allowlist to override.
```

### `filing_search`

- The name "filing_search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search one company's SEC filings. Returns `## Facts` (exact as-reported and restated financial values) and `## Passages` (matching filing text) — both come back in one call.

`ticker` is REQUIRED. When `## Facts` is empty, read `## Passages` — the figure is usually stated in the filing text.

`period_start`/`period_end` match by interval overlap; `fiscal_period` sets granularity (Q1..Q4/H/9M/FY). Pass an explicit period window for the most recent figure.
```

### `get_table_schema`

- The name "get_table_schema" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Column definitions (name, type, description) for a data table, plus its usage note where one exists: required filters, ticker format, and market coverage.
```

### `industry_inflections`

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

Description, as the server wrote it:

```untrusted-server-text
Search industry inflections identified through structured research of earnings calls held by US-listed companies, including the change mechanism, impact scope, market attention and affected companies.

All filters are optional and combine with AND. With no filters, returns the newest first page. Results are ordered by `quarter` descending. If nothing matches, returns the text `No relevant industry inflections found.`

Returns JSON as `{ "data": [...] }`. Every result contains `quarter`, `name` (English title), `regime_type` (change mechanism), `impact_scope`, `impact_degree` (`limited` | `significant` | `structural`), `attention_verdict` (market-absorption judgment), `change_summary`, `first_seen` (`YYYY-MM-DD`), and `source_tickers` (companies whose calls are primary evidence). When `impact_companies` is true, `company_impacts` contains items with `ticker`, `relation`, `direction`, `magnitude`, `impact_stage`, `evidence_status`, `affected_business`, and `impact`.
```

### `list_tables`

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

Description, as the server wrote it:

```untrusted-server-text
List alternative-data tables under the given categories. Returns each table's name,
one-line purpose, and column names (call get_table_schema if you need column
types/comments). Batch up to 5 categories in one call; omit categories, or pass ["all"], to
get the category index instead.

Use this BEFORE run_sql when you want to explore alt-data — run_sql alone won't
tell you which tables exist.

Available categories:
- Energy & Power — US power plants, electricity prices, regional hourly generation/demand
- Data Centers — facilities, GPU clusters, cooling
- Semiconductors — AI chip specs, sales, ownership, foundry revenue, customs trade
- Compute Pricing — GPU rental, cloud VM spot/on-demand, instance specs
- Model Development — model specs, benchmarks, AI companies, AI polling, LLM arena
- Inference Economics — LLM API pricing across providers
- Macro & Trade — UN Comtrade, US Census trade flows, FRED macro series
- Prediction Markets — Polymarket and Kalshi events, markets, trades, daily aggregates
- Critical Minerals — USGS mineral deposits, country supply, critical materials
```

### `news_search`

- The name "news_search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use for any news, event, development, or statement question about a company,
theme, or the market. The `ticker` filter takes exchange-suffixed symbols.

Returns Markdown: a `## Stories` numbered list (each storyline once), then flat
`## Events` and `## Claims` tables (claims = attributed statements: analyst
actions, corporate guidance, central-bank remarks). The Events `story` column
refers back to the Stories number. `sources` counts corroborating reports;
`first_reported`/`last_reported` give the reporting span. Lowest-ranked stories
are dropped to fit length; the meta line flags how many were omitted.

At least one of query/theme/ticker/since/until is required. Per-parameter detail
is on the input schema — search_type=claims needs query/ticker/a time window,
not theme.
```

### `ticker_lookup`

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

Description, as the server wrote it:

```untrusted-server-text
Resolve a company name, brand, or ticker substring to canonical ticker(s).

Input:
- query (required): company name, brand, or ticker substring, e.g. "Apple", "AAPL", "OpenAI"
- market (optional): "us" | "jp" | "cn" — omit to search all markets

Returns up to 5 matches ranked by prefix-hit first, then name length; symbols carry their market suffix.
```
