Wikitree

MCP server exposing WikiTree's genealogy API via the Code Mode architecture. Public profiles only — no authentication required.

Note: GitHub is a read-only mirror. Development happens on GitLab.

Architecture

This server uses 2 meta-tools (search + execute) with 10 operations in a server-side registry. The LLM discovers operations via search and runs them via execute.

Tool	Description
search	Discover available operations and their parameters
execute	Run a named operation against the WikiTree API

Operations

Operation	Category	Description
get_profile	read	Retrieve a person or free-space profile
get_person	read	Retrieve a person profile (person profiles only)
get_people	read	Fetch multiple profiles by keys or relationships
search_person	search	Search profiles by name, dates, location, gender
get_ancestors	analysis	Get ancestor tree (parents, grandparents, etc.)
get_descendants	analysis	Get descendant tree (children, grandchildren, etc.)
get_relatives	read	Get parents, children, siblings, spouses
get_bio	content	Retrieve biography text
get_photos	content	Get photos linked to a profile
get_categories	content	Retrieve associated categories

Environment Variable	Required	Default	Description
WIKITREE_APP_ID	No	Genealogy-MCP_wikitree-mcp	Your application identifier for the WikiTree API
WIKITREE_API_BASE_URL	No	https://api.wikitree.com/api.php	WikiTree API endpoint
WIKITREE_HTTP_TIMEOUT	No	10.0	HTTP request timeout in seconds
WIKITREE_MAX_RETRIES	No	3	Max retry attempts for transient failures

Setup: Claude Desktop

Add to your claude_desktop_config.json:

Using uv (local)

{
  "mcpServers": {
    "wikitree": {
      "command": "uv",
      "args": ["--directory", "/path/to/wikitree-mcp", "run", "wikitree-mcp"],
      "env": {
        "WIKITREE_APP_ID": "your-app-id"
      }
    }
  }
}

Using Docker

{
  "mcpServers": {
    "wikitree": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "WIKITREE_APP_ID=your-app-id", "wikitree-mcp"]
    }
  }
}

Setup: Claude Code

Using uv (local)
