klent-sdk

The Python SDK for Klent — the control + observability layer for AI agents in production. Wraps every tool call your agent makes through Klent's policy engine: allow, deny, modify, steer to a different tool, or pause for approve (human-in-the-loop, synchronous wait via dashboard or email).

Install

pip install klent-sdk

Or with Anthropic agent helpers:

pip install 'klent-sdk[anthropic]'

Quick start

import os
from klent_sdk import KlentClient, run_tool

klent = KlentClient(api_key=os.environ["KLENT_API_KEY"])
execution = klent.start_execution(agent_id="my-agent")

result = run_tool(
    klent,
    execution_id=execution["id"],
    tool="transfer_funds",
    input={"amount": 50_000, "currency": "USD"},
    execute=lambda inp: transfer_funds(**inp),
    approval={"wait": {"timeout_ms": 30 * 60_000}},
)

if result["status"] == "allowed":
    print("output:", result["output"])
elif result["status"] == "denied":
    print("blocked:", result["reason"])

The approval.wait kwarg makes run_tool block synchronously until a human resolves the action on the dashboard (or via the email Resend sends with Approve / Reject buttons), then runs the tool and returns its output.

Anthropic agent helper

A higher-level orchestrator runs an Anthropic agent loop with every tool call gated through Klent:

from anthropic import Anthropic
from klent_sdk import KlentClient
from klent_sdk.anthropic import run_anthropic_agent

result = run_anthropic_agent(
    anthropic=Anthropic(),
    klent=KlentClient(api_key=...),
    agent_id="research-agent",
    system="You are a helpful research assistant...",
    tools=[...],
    user_message="Find the top 3 things...",
)

See klent_sdk/anthropic.py for the full surface.
