## Exfil surface

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

| 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. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__hla-verify__donor_compat` `mcp__hla-verify__pgx_pair` `mcp__hla-verify__translate_names` |

## Findings

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

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

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The input addresses people (input.recipient): what it sends cannot be taken back.
```

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

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

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The input addresses people (input.recipient): what it sends cannot be taken back.
```

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

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

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The input addresses people (input.to): what it sends cannot be taken back.
```


## Can't be undone (3)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `donor_compat`

- The input addresses people (input.recipient): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.recipient): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Donor/recipient immunogenetic compatibility under two published rule sets: HLA-B leader match (-21 M/T, Petersdorf 2020) for a single HLA-B mismatch, and KIR ligand (C1/C2/Bw4) class comparison, computed over each side's full typing QC. Rule checking against published frameworks; it does not rank or recommend a donor. recipient/donor: {"A": [...], "B": [...], "C": [...], "DRB1": [...], ...} (allele strings only, no patient identifiers). Decision support only; not a medical device.
```

### `pgx_pair`

- The input addresses people (input.recipient): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.recipient): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
For a donor-recipient pair, which genome carries each actionable HLA-drug association. Screens both typings as pgx_lookup does and marks every CPIC level-A, allele-positive association in_recipient, in_donor, discordant (present in exactly one) and whose_hla (both / recipient_only / donor_only). Guideline lookup over published CPIC and PharmGKB associations, keyed by two-field HLA allele. Decision support only; not a medical device. After an allogeneic transplant the recipient's blood carries the donor's genome, and which genome should drive an HLA-mediated drug alert is an open question (NCT06856226); this lookup reports both and decides nothing. Allele strings only, no patient identifiers.
```

### `translate_names`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Translate HLA allele names from one IPD-IMGT/HLA release to another, through each allele's HLA ID, using the official Allelelist_history.txt (every release since 1.05.0). Give the names as they were written in release `from` (omit `from` to accept a name used in any release); `to` defaults to the current release. Each row says unchanged, renamed (to_name), deleted (reason, successor and its name in `to`), not_yet_named, not_in_from_release, ambiguous (each allele listed) or unknown. Use it when data typed under an older release has to be compared with or reported under a newer one. Lab shorthand (B*1501, A*02:XX) belongs in normalize_allele first. Allele strings only, no patient identifiers.
```

## Changes things (8)

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

### `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 this server is and is not, what to send it, benchmark evidence for why to use it, the beta state, and terms.
```

### `allele_history`

- 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
Every name the allele behind an HLA name has had, release by release since IPD-IMGT/HLA 1.05.0: its HLA ID, current name, the first and last release that used this name, the full timeline of names, and the deletion note if the name was retired. `as_of` adds what it was called in that release. Use it to answer when a name appeared, changed or disappeared. An allele string only, no patient identifiers.
```

### `allele_info`

- 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
Look up one name in the pinned release and return what it is: assigned (G/P group, first release, confirmed status, WMDA serology, null flag), valid_prefix (member count and sample, plus resolution: what a name with fewer than four fields does and does not distinguish), group (a G or P group name: member count and sample), or deleted (successor). Reported shorthands are accepted as /v1/normalize accepts them — legacy spellings (A*0101, Cw*0702, Cw*07:02), the XX code (A*02:XX), two-field A*02:01g, an optional HLA- prefix — and answer with the facts of the name they stand for plus resolves_to and a flag (deprecated_name, xx_code, lg_notation); an NMDP multiple allele code (A*02:AB) returns mac_code, recognised but not expanded. Not found if the name has never existed in any release.
```

### `beta_signup`

- The description's first verb is "put": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Put a user on the free public beta's notification list for paid API keys. Ask before calling: it records the address they give you. Re-signing the same address is safe (status already_recorded). Someone who needs a higher rate limit today should email hello@hlaverify.com for a beta key instead of waiting.
```

### `check_typing`

- 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
QC-check one HLA typing (all loci) against the pinned release: resolves every reported allele, flags unresolvable/outdated/locus-mismatched/null alleles, flags too-many/single/homozygous per locus, computes the B-leader (-21 M/T) and KIR-ligand (C1/C2/Bw4) profile, and DRB3/4/5 expected-vs-reported. Nomenclature and internal-consistency checking of the report, not clinical interpretation. typing: {"A": ["A*01:01", "A*02:01"], "B": [...], "DRB1": [...], ...} (any nomenclature era, G/P group names, A*02:XX and two-field A*02:01g included; NMDP MAC codes are flagged, not expanded; allele strings only, no patient identifiers).
```

### `normalize_allele`

- 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
Normalize one reported HLA allele name (any era or reporting shorthand: legacy A*0101, Cw*0702 or Cw*07:02, G/P group names, A*02:XX, two-field A*02:01g, optional HLA- prefix) to current 2-field form, with G group, P group, serologic equivalent, and flags. NMDP MAC codes (A*02:AB) are recognised but not expanded (flag mac_code).
```

### `research_access`

- The description's first verb is "apply": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Apply for free HLA-Verify access for an academic or nonprofit lab. Ask before calling: it records the address, institution and use case you give it. Approval is manual: a person reads every application, so it is not instant and not guaranteed. If it is approved the applicant is emailed a single-use code that takes 100% off a subscription for 12 months at self-serve checkout, with no card and no contract. Re-applying with the same address is safe (status already_recorded) and never overwrites an application that has already been decided. Commercial labs should buy a tier at https://api.hlaverify.com/pricing instead.
```

### `verify_text`

- 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
Scan HLA typing report text, or model output about HLA, for allele-shaped tokens and classify each one: valid / legacy spelling such as A*0201 or Cw*0702 (valid, with modern form and flag deprecated_name) / G-P group / deleted (with successor) / fabricated / NMDP MAC code (seen, not expanded) / KIR name (out of scope, not checked); a valid token with fewer than four fields carries resolution, what that field count does and does not distinguish. Nomenclature checking against a pinned IPD-IMGT/HLA release, not interpretation of a case. Use on any AI-generated or transcribed content mentioning HLA. Send the HLA content only, with patient identifiers removed first.
```

## Only reads (4)

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

### `match_score`

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

Description, as the server wrote it:

```untrusted-server-text
Count a donor-recipient HLA match by the published counting rules (R1-R6): allele arithmetic over chromosomes, not a donor recommendation. recipient/donor: {"A": ["A*01:01","A*02:01"], "B": [...], ...} (two reported alleles per locus, any nomenclature era including G/P group names such as A*02:01:01G; allele strings only, no patient identifiers). framework: 6/6, 8/8, 10/10, 12/12, or antigen. Returns count, per-locus verdicts, GvH/HvG mismatch counts, and flags; unresolvable typing yields 'potential', never a confident count.
```

### `pgx_lookup`

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

Description, as the server wrote it:

```untrusted-server-text
Which drugs an HLA typing carries a published pharmacogenomic association for. Looks each allele up in hla-pgx-open (CPIC guidelines + PharmGKB clinical annotations, CC BY-SA, snapshot date in every answer) after normalizing the name first, so any era or shorthand works (A*3101, B*5701, HLA-B*15:02:01G) and every conversion leaves a flag. Returns per allele the current name, the two-field form, the flags and the associations (source, drug, evidence level, CPIC testing recommendation, implication, recommendation, guideline or annotation URL, PMIDs), plus summary.actionable: the CPIC level-A, allele-positive rows. Guideline lookup over published CPIC and PharmGKB associations, keyed by two-field HLA allele. Decision support only; not a medical device. After an allogeneic transplant the recipient's blood carries the donor's genome, and which genome should drive an HLA-mediated drug alert is an open question (NCT06856226); this lookup reports both and decides nothing. Allele strings only, no patient identifiers.
```

### `release_diff`

- The name "release_diff" says "diff": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Which HLA allele names were added, removed (with the deletion reason and successor) and renamed between two IPD-IMGT/HLA releases, optionally for one locus. Counts are complete; each list is cut at `limit` and `truncated` says so. Use it to see what a release update changes before re-running or re-reporting typings.
```

### `validate_gl_string`

- The name "validate_gl_string" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Validate and normalize a GL String (Genotype List, ^ | + ~ / grammar): resolves every allele token, flags outdated/unresolvable names and structural problems (mixed loci within a slash-list, a repeated locus within a haplotype or across ^ blocks, more than two haplotypes, differing loci across a genotype or genotype list, empty elements), and returns the normalized string. Grammar and nomenclature checking only; send allele names, not patient identifiers.
```
