Python

from kynth import Kynth

client = Kynth(api_key=os.environ["KYNTH_API_KEY"])
result = client.normalize(
    records=[
    {
      "name": "SMITH, jon",

MCP

// One-time setup in your MCP client (Claude, Cursor, …):
{ "mcpServers": { "kynth-core": {
    "command": "npx", "args": ["@kynth/api-mcp"],
    "env": { "KYNTH_API_KEY": "ksk_live_…" } } } }

// Then the agent just calls the kynth_normalize tool.
