Agent memory

Store, search, and forget memories for your agents — semantic recall on your own namespace, no vector DB to run.

Every response carries usage — the credits burned and your remaining balance. A failed call never burns credits.

Python

from kynth import Kynth

client = Kynth(api_key=os.environ["KYNTH_API_KEY"])

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_memory tool.
