Zovo Family Tree MCP

Zovo Family Tree MCP turns a list of relatives into a correctly laid-out family tree poster or GEDCOM file. It supports five chart types, handles complex relationships like half-siblings and adoptions, and exports to vector PDF, SVG, or GEDCOM 5.5.1. It also identifies how two people are related.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Zovo Family Tree lays out family trees (all relatives, descendants, pedigree/ancestors, hourglass, fan) as print-ready SVG and PDF posters plus a GEDCOM file, and names relationships between two people. Convert the user's description into the people list (id, name, born, died, sex, parents, spouses) and call the tool; do not invent relatives or dates.

generate_family_tree — Generate family tree chart
Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user wants a family tree, genealogy chart, pedigree chart, descendant chart, hourglass chart, fan chart or a printable family tree poster or template from relatives they describe. Convert the description into people (id, name, born, died, sex, parents, spouses) and call once. Lays out generations, couples, remarriages, half-siblings, adoption and twins without overlaps; returns a zoomable chart, PDF posters (Letter, A4, A2, 18x24, 24x36 in), SVG and a GEDCOM 5.5.1 file. Does not research ancestors, find records, or import GEDCOM files; do not invent relatives or dates. Not for organisation charts or flowcharts.

find_relationship — Find relationship between two relatives
Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user asks how two people in their family are related (for example second cousin once removed, great-aunt, half-brother, mother-in-law, stepsister) and gives the family links. Pass the same people list as for the family tree and the two people. Computes the exact English kinship term both ways, the closest common ancestors and the generations to them. Does not guess missing links or research genealogy records; DNA matches and percentages are not covered.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http zovo-family-tree-mcp https://family-tree.zovo.one/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add zovo-family-tree-mcp --url https://family-tree.zovo.one/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable zovo-family-tree-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "zovo-family-tree-mcp": {
      "url": "https://family-tree.zovo.one/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "zovo-family-tree-mcp": {
      "type": "streamableHttp",
      "url": "https://family-tree.zovo.one/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start zovo-family-tree-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "zovo-family-tree-mcp": {
      "type": "http",
      "url": "https://family-tree.zovo.one/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http zovo-family-tree-mcp https://family-tree.zovo.one/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
{
  "mcpServers": {
    "zovo-family-tree-mcp": {
      "url": "https://family-tree.zovo.one/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "zovo-family-tree-mcp": {
      "serverUrl": "https://family-tree.zovo.one/mcp"
    }
