Endpoint Security63
Transport & Reachability100
Schema Quality & AI Usability76
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 1003 tokens (~111/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management37
  • Stability observed for 11 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage84
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 52% of tool parameters carry a description.Partial
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

Install

How do I install the TheYtree MCP server?

TheYtree is a hosted endpoint at https://www.theytree.com/api/v1/agent/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 9 exposed · ~1,003 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Common questions

What is the TheYtree MCP server?

TheYtree is an MCP server listed in the public MCP registry as com.theytree/theytree. 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。 This page covers its hosted endpoint (https://www.theytree.com/api/v1/agent/mcp).

Is the TheYtree MCP server safe to use?

TheYtree scores 68 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the TheYtree MCP server expose?

TheYtree exposes 9 tools: list_haplogroups, get_haplogroup, get_haplogroup_mutations, get_haplogroup_lineage, children_haplogroups, and 4 more. Their descriptions and schemas cost roughly 1,003 tokens of context every time the server is loaded.

Does the TheYtree MCP server require authentication?

No. We connected to TheYtree without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the TheYtree MCP server still maintained?

TheYtree is still listed as active in the MCP registry. We last reached this channel on 28 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
