HLA-Verify MCP server

• Registry namecom.hlaverify/hla-verifyverified in the MCP registry

The registry name sits under hlaverify.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-24 the server answered initialize and tools/list without a sign-in. First answer in 279 ms.

• Its tools do every use case we checked: check allele names in typing reports against a pinned release; flag fabricated or deleted allele names in model output; normalize legacy typings to current nomenclature.
• Checked on 4 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• verify_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…

• normalize_allele

  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…

• allele_info

  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…

• match_score

  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…

• check_typing

  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…

• donor_compat

  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…

• validate_gl_string

  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 ^…

• pgx_lookup

  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…

• pgx_pair

  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…

• translate_names

  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`…

• release_diff

  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…

• allele_history

  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…

• beta_signup

  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…

• research_access

  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…
