祖源树TheYtree MCP server

• Registry namecom.theytree/theytreeverified in the MCP registry

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

On 2026-10-18 the server answered initialize and tools/list without a sign-in. First answer in 309 ms.

• Whether its tools do the product's job has not been judged yet.

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 →

• list_haplogroups

  Search or list paternal haplogroups by fuzzy name and/or parent, with stable ordering for full pagination (order=name recommended). 搜索/列出父系单倍群：按名称模糊匹配、按父节点筛选，稳定排序可完整枚举。

• get_haplogroup

  Get a single haplogroup by name / hid / SNP. 按名称/hid/SNP 获取单个单倍群详情。

• get_haplogroup_mutations

  List a haplogroup defining (equivalent) mutations (paternal / Y tree only). 获取某单倍群的等价突变（defining SNPs）列表（仅父系 Y 树）。

• get_haplogroup_lineage

  Get the lineage chain from a haplogroup up to ROOT. Use limit to fetch only the most recent N levels (e.g. limit=2 for the node + its parent). 获取某单倍群上溯到 ROOT 的谱系链；可用 limit 只取最近 N 级（如 limit=2 即该节点与其直接父级）。

• children_haplogroups

  Get the direct children of a haplogroup (for level-by-level traversal). Use limit for the N largest subclades only. 获取直接子节点（逐层遍历）；可用 limit 只看最大的 N 个分支。

• resolve_snp

  Resolve a SNP name to its haplogroup and return equivalent names (merged-name variants supported). 将 SNP 名解析到所属单倍群并返回等价名。

• resolve_snps

  Batch-resolve up to 200 SNP names to their haplogroups (for reading a whole Y-SNP panel). 批量解析多个 SNP 名到所属单倍群（≤200/次）。

• subtree_haplogroups

  Get a haplogroup subtree. Defaults to 6 levels (matches the site); small branches (root endcounts<=600) fully expand; max_depth overrides. Truncated boundary nodes carry has_children. 取子树：默认 6 层，小支(endcounts<=600)全展开，可传 max_depth；截断边界带…

• get_api_info

  Get service meta: summary, auth, dataset size (haplogroups / mutation records), and the tool list. 获取本服务元信息：简介、鉴权、数据集规模、工具清单。
