## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `support_helena`

- 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
Learn about the separate Helena Good MCP. This opt-in information action initiates no payment or outreach and changes no scientific result.
```

## Only reads (6)

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

### `get_corpus_summary`

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

Description, as the server wrote it:

```untrusted-server-text
Return public corpus coverage, source, freshness, and count metadata. Results are for literature discovery and professional review, not diagnosis or treatment.
```

### `get_publication_details`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve one complete public bibliographic record by PMID after search. Results are for literature discovery and professional review, not diagnosis or treatment.
```

### `get_publication_neighborhood`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve the bounded citation and semantic neighborhood around one PMID. Results are for literature discovery and professional review, not diagnosis or treatment.
```

### `get_work_details`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve one complete public bibliographic record by Noodle work identifier. Results are for literature discovery and professional review, not diagnosis or treatment.
```

### `get_work_neighborhood`

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

Description, as the server wrote it:

```untrusted-server-text
Retrieve the bounded citation and semantic neighborhood around one Noodle work identifier. Results are for literature discovery and professional review, not diagnosis or treatment.
```

### `search_biomedical_literature`

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

Description, as the server wrote it:

```untrusted-server-text
Semantically search Noodle's public PubMed-derived biomedical corpus. Include known PMID, DOI, or PMCID identifiers in the query so they can act as exact anchors. Results are for literature discovery and professional review, not diagnosis or treatment.
```
