## 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,"idempotentHint":true,"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
Run one read-only ClickHouse SELECT against the global_markets database and get the rows back. No key needed. Limits on this access: 500 rows and 20 seconds per query, history from 2025-01-01, and some tick-level tables excluded — each result states which limit, if any, it ran into. Connected with an API key, it runs at that key's plan instead. Docs: https://ai.strasmore.com/llms.txt (tables and limits), https://api.strasmore.com/docs (API reference).
```

## Only reads (3)

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

### `describe_table`

- The name "describe_table" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Columns of one table with their ClickHouse types, plus notes on columns whose meaning is not obvious from the name and known data caveats. Call before writing SQL against a table.
```

### `get_plans`

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

Description, as the server wrote it:

```untrusted-server-text
What this no-key access includes, what a free account and each paid plan add (history depth, datasets, row limits, price), and the link to start each one.
```

### `list_tables`

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

Description, as the server wrote it:

```untrusted-server-text
List every table in the Strasmore US market-data warehouse (equities, options, corporate actions, fundamentals, SEC filings, news, macro) with a one-line description, the column its history window filters on, and whether this no-key access can read it. Call this first.
```
