## 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__pharmacogenomics-guidelines__pgx_get_guideline` `mcp__pharmacogenomics-guidelines__pgx_get_recommendations` `mcp__pharmacogenomics-guidelines__pgx_list_reference` `mcp__pharmacogenomics-guidelines__pgx_lookup_diplotype` `mcp__pharmacogenomics-guidelines__pgx_search_alleles` `mcp__pharmacogenomics-guidelines__pgx_search_pairs` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

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

### `pgx_get_guideline`

- The name "pgx_get_guideline" 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
Retrieve guideline coverage by source ID, exact gene symbol or exact drug name/ID. Default summary pages complete guideline records with exact drugCount/pairCount. view=drugs or pairs requires by=id and pages only that related collection, retaining its guideline descriptor. Ambiguous drug names page candidates for retry with drugId. Follow page.nextOffset; the 24,000-byte soft budget cuts only between complete rows, with oversizedRow for an indivisible exception. Missing coverage is found=false. Consult linked guidelines before clinical use.
```

### `pgx_get_recommendations`

- The name "pgx_get_recommendations" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "browse": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Browse CPIC recommendations in drug mode with one exact drugName or drugId. Match across drugs in results mode with geneResults or geneSymbol plus phenotype/activityScore, or genotype mode with 1–10 uniquely resolved gene/diplotype entries. Both matching modes accept an optional drug. Optional view=test_alerts selects complete example CDS alerts instead of recommendations, without joins; default view=recommendations. Alert records retain ordered alerttext, No CDS and n/a. Use pgx_list_reference topic phenotypes for source values. Every matched prerequisite must be explicit; omitted genes are never normal, negative or No Result. Preserve populations, scores, classifications and source text. Follow page.nextOffset and incompletePage.nextOffset independently for the selected collection and missing-gene diagnostics; consult source guidelines before clinical use.
```

### `pgx_list_reference`

- The name "pgx_list_reference" says "list": 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
Inspect gene symbols, gene-specific source results, CPIC levels, ClinPGx testing labels, recommendation classifications and input formats. phenotypes requires geneSymbol and preserves distinct activity-score rows, frequencies and consultation text. Live genes/phenotypes support paging; static topics return their complete vocabulary without upstream requests. Use returned values in subsequent discovery, diplotype and recommendation calls.
```

### `pgx_lookup_diplotype`

- The name "pgx_lookup_diplotype" says "lookup": 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
Translate a CPIC-supported diplotype or allele-status result for one gene. Supply geneSymbol and exact diplotype notation, including star alleles, named HLA positive/negative statuses, or non-star sequences; use pgx_search_alleles and pgx_list_reference with topic phenotypes to inspect supported values. Exact lookup precedes bounded reverse-order or status aliases. Multiple source rows remain ambiguous; no activity score or missing gene result is inferred.
```

### `pgx_search_alleles`

- The name "pgx_search_alleles" says "search": 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
Inspect CPIC allele function, evidence, definition metadata and complete population frequencies for geneSymbol. Name matches literally first, then a matching gene prefix before a star allele may be removed; clinicalFunctionalStatus matches literal text case-insensitively. Discover genes with pgx_list_reference. Definitions are metadata, not variant interpretation. Frequencies are source fractions; inferred frequencies are not observations and do not establish individual risk. Pages have a 24,000-byte complete-result soft budget; an indivisible exception sets oversizedRow. Continue with page.nextOffset.
```

### `pgx_search_pairs`

- The name "pgx_search_pairs" says "search": 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
Search evaluated gene–drug pairs by gene, literal drug-name substring, exact drug/RxNorm/ATC identifiers, evaluation level or testing label. Filters combine with AND; identifiers never fall back to name-only search. Results include source drug identifiers and guideline links for pgx_get_guideline. A pair evaluation is not a prescribing recommendation. Follow nextOffset to continue.
```

## Claude Code permissions
