TheYtree is a remote MCP server that gives an AI agent 9 tools, among them children_haplogroups, get_api_info, get_haplogroup. It answers at https://www.theytree.com/api/v1/agent/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 4 of 4 times since 17 September 2026; the last check, on 24 October 2026, succeeded.
Public read-only MCP for the Y-chromosome haplogroup tree & Y-SNP resolution. 父系单倍群树查询与Y-SNP解析。
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
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。 Inputs: name, limit |
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。 |
get_haplogroup | Get a single haplogroup by name / hid / SNP. 按名称/hid/SNP 获取单个单倍群详情。 Inputs: name |
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）。 Inputs: name, limit |
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）。 Inputs: name, include_under_observation, compact, fields, page, per_page |
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。 Inputs: name, parent, level, order, order_dir, exclude_mf |
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。 Inputs: snpname |
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）。 Inputs: snpnames |
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 has_ Inputs: name, max_depth |

It answered our last check on 24 October 2026 in 1223 ms. Over 4 checks since 17 September 2026 it answered 4. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by theytree.com and served from www.theytree.com, the vendor's own domain: https://www.theytree.com/api/v1/agent/mcp.
9, as returned by the server's own tools/list on 24 September 2026: children_haplogroups, get_api_info, get_haplogroup, get_haplogroup_lineage, get_haplogroup_mutations, list_haplogroups, resolve_snp, resolve_snps, and 1 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://www.theytree.com/api/v1/agent/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 17 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
