Your agent needs a person. They do not need an account.
Send a review to anyone: a client, an accountant, the colleague who signs off deliveries. They get a link, answer the question, and your agent carries on. No signup, no password, no seat to buy for the person doing the reviewing.
It runs on an MCP server, native LangGraph tools and a Python SDK, so the request is a few lines from wherever your agent already lives.
What your agent gets when it needs a person
A way to ask, somewhere for the answer to come back to, and a record of who decided what.
Reviewers need no account
Send a case to any email address. They open a link, answer, and that is it. Nobody has to sign up, be invited, or take up a seat, so the person who actually knows the answer can be the one who gives it.
MCP-Compliant HITL Server
Adopt the industry standard for HITL. KirokuForms provides a ready-to-use MCP server, ensuring interoperability and simplifying how your AI requests human judgment.
Native LangGraph Checkpoints
Directly embed human review steps into LangGraph agents using our native tools. Manage interrupt() and state for complex AI workflows.
Python SDK & Developer APIs
Integrate HITL in minutes. Our Python SDK and clear APIs abstract complexity, letting you define tasks and retrieve structured results programmatically.
Dynamic Review Forms
Use our core form engine to dynamically generate tailored review interfaces for any data type or AI output, ensuring structured and relevant feedback.
Integrate Human Insight Your Way
KirokuForms offers flexible integration patterns to fit your existing AI architecture and development practices.
Use KirokuForms as an MCP Server
Implement standardized Human-in-the-Loop by connecting your AI systems to KirokuForms via the Model Context Protocol. Submit tasks, define review forms dynamically, and receive structured feedback. Every task lands as a case with an owner, a status, and an activity trail, so a person can pick it up and see it through to an outcome. See lightweight case management.
- Fully MCP v0.2 compliant (or target version).
- Handles task queuing, assignment (future), and reviewer UI.
- One authenticated endpoint for every review your agents raise.
from kirokuforms_mcp import MCPClient
client = MCPClient(api_key="YOUR_API_KEY")
# Create a simple review task
task = client.create_task(
title="Review Generated Content",
fields=[
{"name": "content", "type": "textarea", "label": "Generated Text"},
{"name": "approved", "type": "radio", "label": "Approve?",
"options": [{"label": "Yes", "value": "yes"}, {"label": "No", "value": "no"}]}
]
)
print(f"Review at: {task['formUrl']}")Native LangGraph Tool/Node
For LangGraph users, KirokuForms offers (or will offer) a dedicated node to easily insert human review checkpoints into your agentic workflows. Simplify `interrupt()` handling and manage human feedback loops.
- Drop-in component for LangGraph agents.
- Manages state and callbacks for human review.
- Uses KirokuForms' dynamic form capabilities for review UIs.
from langgraph.graph import StateGraph
from kirokuforms_langgraph import KirokuFormsHITLNode
# Add human review to your LangGraph workflow
workflow = StateGraph(AgentState)
workflow.add_node("agent_step", your_agent_logic)
workflow.add_node("human_review", KirokuFormsHITLNode(
api_key="YOUR_API_KEY",
form_template="review_template"
))
# Route to human review when needed
workflow.add_conditional_edges(
"agent_step",
lambda state: "human_review" if state.get('needs_review') else END
)Convenient Python SDK
Our Python SDK (`kirokuforms` or `kirokuforms-hitl`) provides a high-level interface to interact with all KirokuForms HITL services, including task submission, dynamic form definition, and results retrieval.
- Easy installation via pip.
- Simplifies authentication and API calls.
- Built for rapid integration into your Python-based AI projects.
from kirokuforms import KirokuClient
client = KirokuClient(api_key="YOUR_API_KEY")
# Create a dynamic review form
task = client.hitl.create_task(
title="Content Moderation",
fields=[
{"name": "content_id", "type": "text", "label": "Content ID"},
{"name": "action", "type": "select", "label": "Action",
"options": ["Approve", "Reject", "Escalate"]},
{"name": "notes", "type": "textarea", "label": "Notes"}
]
)
print(f"Task ID: {task.id}")Overcome Your Human-in-the-Loop Hurdles
KirokuForms addresses common pain points in implementing and scaling human review for AI.
Custom HITL UI Development
The Problem
Building and maintaining bespoke UIs for human review tasks is a significant engineering overhead, diverting focus from core AI model development.
Our Solution
Offload UI/UX to KirokuForms' pre-built, dynamic, and user-friendly review interfaces. Define forms via API or templates; we render and manage the review experience.
Key Benefits
- Reduce frontend development time
- Ensure consistent reviewer UX
- Focus entirely on AI logic
Costly & Complex Platforms
The Problem
Traditional enterprise HITL platforms can be prohibitively expensive, slow to implement, and lack the flexibility needed for agile AI teams or research.
Our Solution
KirokuForms offers a developer-friendly, self-serve model with transparent and competitive pricing. Get started quickly and scale HITL affordably as your needs grow.
Key Benefits
- Lower total cost of ownership
- Faster time-to-value for HITL
- Flexible plans for all team sizes
Lack of Standardization
The Problem
Ad-hoc HITL solutions for different AI projects lead to brittle, hard-to-maintain workflows and prevent reusability of review processes.
Our Solution
One protocol and one API for human review, so the same review process serves every project instead of being rebuilt per agent.
Key Benefits
- Improved interoperability
- Consistent review processes
- Easier scaling of HITL operations
Powering Diverse AI Applications
From validating outputs to collecting nuanced feedback, KirokuForms supports a wide range of HITL needs.
AI Model Output Validation
Content Moderation Review
Complex Data Annotation
Exception Handling in Agents
Human Feedback for RLHF
Research Data Verification
