## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__genebe__annotate_variant` `mcp__genebe__convert_variant` `mcp__genebe__explain_acmg_decision_path` `mcp__genebe__get_gene` `mcp__genebe__get_variant_effects` `mcp__genebe__liftover_coordinate` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

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

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

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

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The description's first verb is "convert": a word for a change.
```


## Changes things (3)

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

### `annotate_variant`

- 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.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Annotate and classify one human genetic variant using GeneBe.

Start here for any question about a variant (what is it, is it pathogenic/benign, how common is it).
Returns the ACMG verdict with points and criteria, population frequency (gnomAD), predictor scores
(REVEL, AlphaMissense, SpliceAI, ...), ClinVar status, transcript consequences, and links to the
GeneBe page to cite. Research use only; not a diagnosis.

```

### `convert_variant`

- The name "convert_variant" says "convert": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Convert a variant written in any notation into normalized hg38 genomic coordinates.

Use when you only need the chr/pos/ref/alt of a variant (for example to translate HGVS or an rsID),
without annotation. Does not classify the variant; use annotate_variant for that.

```

### `liftover_coordinate`

- The description's first verb is "convert": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Convert a genomic position, interval or variant between genome builds (hg19, hg38, t2t).

Check `status`: RESOLVED means one result, AMBIGUOUS means several candidates, anything else
means it could not be mapped (see errors). For variants, ref/alt are rebuilt against the target
reference and warnings such as REF_MISMATCH may apply.

```

## Only reads (3)

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

### `explain_acmg_decision_path`

- The name "explain_acmg_decision_path" says "explain": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Explain step by step why each classification criterion did or did not apply to a variant.

Use after annotate_variant when the user asks "why was this classified that way?". Returns an
ASCII rendering of the decision tree with the evaluated conditions. By default it explains the
germline ACMG verdict that annotate_variant returns; the somatic trees 'oncogenicity' (2022) and
'acgs-uk-onco' (2025) can be requested explicitly. Research use only.

```

### `get_gene`

- The name "get_gene" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Look up a human gene: identifiers, location, MANE Select transcript, ClinGen gene-disease validity.

Use for questions about a gene rather than a specific variant. Transcripts are listed with
MANE Select first and capped; check total_transcripts.

```

### `get_variant_effects`

- The name "get_variant_effects" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
List a variant's predicted molecular consequences on every overlapping transcript.

Returns per-transcript HGVS (c. and p.), consequence terms (e.g. missense_variant) and impact,
most severe and MANE Select transcripts first. Lightweight: no frequencies or classification.

```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `genebe`:

```json
{
  "permissions": {
    "allow": [
      "mcp__genebe__explain_acmg_decision_path",
      "mcp__genebe__get_variant_effects",
      "mcp__genebe__get_gene"
    ],
    "ask": [
      "mcp__genebe__annotate_variant",
      "mcp__genebe__convert_variant",
      "mcp__genebe__liftover_coordinate"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__genebe__annotate_variant`: untrusted-input
- `mcp__genebe__explain_acmg_decision_path`: untrusted-input
- `mcp__genebe__convert_variant`: untrusted-input
- `mcp__genebe__get_variant_effects`: untrusted-input
- `mcp__genebe__get_gene`: untrusted-input
- `mcp__genebe__liftover_coordinate`: untrusted-input

| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.genebe.net/v1/mcp: tools/list returned 6 tools to an anonymous client, including annotate_variant (write), convert_variant (write), liftover_coordinate (write)
```
