## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `tradebasis_about`

- 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
What TradeBasis is, the problem it solves, what makes it different, and who it's for, plus how to connect to the separate free, limited US appraisal pilot. Static markdown; as_of is the explicit content review date.
```

### `tradebasis_pricing_and_tiers`

- 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
TradeBasis paid subscription tiers — Lite (1 user, $99/mo USD) vs Pro (up to 10 users, $249/mo USD). Separate from the free MCP appraisal pilot and the $99 one-time consumer report. Static markdown; as_of is the explicit content review date.
```

### `tradebasis_vin_decode`

- 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
Decode a 17-character VIN into vehicle identity: year, make, model, trim, body style, drivetrain, engine, transmission and fuel type. Hybrid, plug-in hybrid and battery-electric vehicles also return their electrification level and, where stated, battery and charging facts. Identification only — this tool returns no valuation, no comparable listings and no market data.
```

## Only reads (1)

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

### `tradebasis_research_library`

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

Description, as the server wrote it:

```untrusted-server-text
Search published TradeBasis US dealer research, BHPH (buy here pay here) economics and portfolio benchmarks, the experimental BHPH Macro Conditions Index and its methodology, public blog articles, and legacy briefs. No arguments lists the catalog. topic retrieves a document by ID/slug/title; topic + section retrieves a section or continuation part. query searches; optional limit is an integer 1–20 (default 5). These modes cannot be combined. Returns published Markdown tables, dated evidence, sources and qualifications, not new financial analysis. Long documents return an overview and section directory. Publication is rechecked on every retrieval; unverifiable sources return retryable errors, not cached article text. Blog access uses the public internet. Publication/update dates, CMS modification, data coverage and retrieval time are distinct. Structured output uses operation=list/search/get/section/invalid; retrieval includes the requested Markdown and publisher caveats. Unknown dates and coverage remain null. No search cursor is supported; use returned section/part IDs for long content.
```
