## Exfil surface

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

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

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `check_medications`

- 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
Given a list of generic drug names, say which ones have a curated drug–gene record, with which genes and what each record rests on (a CPIC or DPWG guideline, a drug label, or the primary literature), and which are not covered. Needs no genotype. Use it before discussing whether genetics could matter for someone's medicines.
```

### `request_beta_access`

- The name "request_beta_access" says "request": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Register the user's interest in DeepDNA's private beta (DNA file parsing, annotation, bloodwork; not deployed yet). Only call this after the user has explicitly agreed to share their email with DeepDNA for this purpose, and set user_consent to true. Stores the email and the optional use case; see https://deepdna.ai/privacy/.
```

## Only reads (4)

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

### `list_genes`

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

Description, as the server wrote it:

```untrusted-server-text
List the genes in the DeepDNA knowledge base, with a one-line summary and category for each.
```

### `lookup_drug_gene`

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

Description, as the server wrote it:

```untrusted-server-text
Pharmacogenomic guidance for a gene, optionally for one drug: guideline (CPIC or DPWG, "drug label", or null when the record rests on the primary literature), summary of the recommendation, phenotypes and sources. Omit drug to list every drug curated for that gene.
```

### `lookup_gene`

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

Description, as the server wrote it:

```untrusted-server-text
Everything curated about one gene: function, key variants with rsIDs, metabolizer or function phenotypes, drug interactions, what a consumer genotyping array can and cannot tell you, and sources.
```

### `lookup_variant`

- The name "lookup_variant" says "lookup": a word for reading.
- Tag private-data: The description's first sentence says "db": it reads databases.

Description, as the server wrote it:

```untrusted-server-text
One variant by dbSNP rsID: gene, star-allele or common name, alleles, functional effect, population frequency and sources. Send the rsID only, never the user's genotype. To compare a raw DNA file, do it in the agent with the record's reading block (GRCh37 plus-strand reference and variant allele): skip it when countable is false, don't trust A/T or C/G positions (strand_ambiguous) unless the file's strand is known, and treat a chip call of a rare pathogenic variant as unconfirmed. A count at one position is not a phenotype or metabolizer status.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__knowledge__list_genes",
      "mcp__knowledge__lookup_gene",
      "mcp__knowledge__lookup_variant",
      "mcp__knowledge__lookup_drug_gene"
    ],
    "ask": [
      "mcp__knowledge__check_medications",
      "mcp__knowledge__request_beta_access"
    ],
    "deny": []
  }
}
```

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

- `mcp__knowledge__lookup_variant`: private-data

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:19:38.517Z, unchanged since 2026-10-22T14:19:38.517Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |

| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `2` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |

- **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 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://deepdna.ai/mcp: tools/list returned 6 tools to an anonymous client, including check_medications (write), request_beta_access (write)
