Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (6)
🟢search_person(query, limit)
Search the Human Lineage genealogical graph for a person by name. Returns matches with their profile URL.
Input Schema
{
"type": "object",
"properties": {
"query": {
"type": "string",
"minLength": 2,
"description": "Name (or part of a name) to search for"
},
"limit": {
"description": "Max results (default 10, max 20)",
"type": "integer",
"minimum": 1,
"maximum": 20
}
},
"required": [
"query"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_person(id)
Get full details for a person by their Human Lineage ID, including a link to their profile.
Input Schema
{
"type": "object",
"properties": {
"id": {
"type": "string",
"description": "Person ID, e.g. as returned by search_person"
}
},
"required": [
"id"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_relatives(id)
Get the immediate family (parents, children, spouses) of a person as TEXT, with profile URLs. Use get_family_image instead if the user wants to see a picture/visual/graphic of the family tree.
Input Schema
{
"type": "object",
"properties": {
"id": {
"type": "string",
"description": "Person ID to look up relatives for"
}
},
"required": [
"id"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢get_family_image(id)
Returns a markdown image () of a visual family-tree card showing a person's parents, spouse and children. Use this — not get_relatives — whenever the user asks to see, show, view, or display a family tree, family diagram, or picture of the family. IMPORTANT: include the returned markdown image line verbatim in your reply so it renders for the user.
Input Schema
{
"type": "object",
"properties": {
"id": {
"type": "string",
"description": "Person ID to render a family card for"
}
},
"required": [
"id"
