Chrome 146+ Origin Trial — Live Now
Get Found & Used by AI Agents, Not Just Google
Leominix implements Chrome’s WebMCP standard, giving AI agents a structured, reliable way to interact with your web pages. No more guesswork actuation. Just precise, repeatable results.
The Problem We Solve
A Direct Line Between Your Site and Any
AI Agent
Traditionally, AI agents “guess” how to interact with your website — clicking buttons, filling fields, and navigating menus by visual inference. WebMCP changes this: you declare exactly what your tools do, and agents follow those instructions precisely.
This means fewer errors, faster task completion, and a consistent experience whether the end-user is a human or an AI model acting on their behalf.
- Agents interact via declared schemas, not fragile UI scraping
- Consistent, repeatable outcomes across any AI platform
- Zero impact on human user experience — fully transparent overlay

IMPERATIVE API — Registering a Dynamic JavaScript Tool
======================================================== –>
<script>
// 1. Define your actual local website function
function handleBookingSubmission(args) {
console.log(“AI Agent triggered booking with data:”, args);
// Your website logic here (e.g., fetch, update UI, state changes)
}
// 2. Register it seamlessly to the browser’s model context
navigator.modelContext.registerTool({
name: ‘submit_booking’,
description: ‘Complete a reservation’,
inputSchema: {
type: ‘object’,
properties: {
date: { type: ‘string’, description: ‘The booking date (YYYY-MM-DD)’ },
guests: { type: ‘number’, description: ‘Total number of guests’ },
room_id: { type: ‘string’, description: ‘The specific room ID’ }
},
required: [‘date’, ‘guests’, ‘room_id’]
}
}, handleBookingSubmission);

What We Deliver
A Full WebMCP Implementation
Tool Registration & Architecture
We design and implement the full tool schema for your site, mapping every agent-accessible action with correct JSON Schemas, parameters, and outputs.
Declarative HTML Annotation
Using Chrome's Declarative API, we annotate your existing HTML forms with tool attributes — making them instantly agent-readable without major refactoring.
Security & Permissions Policy
We configure origin isolation, permissions policies, and cross-origin iframe rules, ensuring your WebMCP tools are exposed safely and correctly.
State Management
We implement real-time page context sharing so agents always know the current state of available products, active session data, or live inventory.
Evals & Agent Testing
Using Chrome's Model Context Tool Inspector and the WebMCP Evals framework, we rigorously test every tool before launch to verify accuracy and reliability.
Progressive Enhancement
WebMCP layers cleanly over your existing site. Human users see no difference; only AI agents gain the new capability, keeping your UX fully intact.
Our Process
From Brief to Browser-Ready
A structured engagement built around your site’s specific agent use cases.
01
Discovery & Audit
We map your site’s key flows checkout, booking, support, search and identify which actions are worth exposing as agent tools.
02
Tool Schema Design
We draft the full tool catalogue: names, descriptions, parameter types, and expected outputs documented as a JSON Schema spec.
03
Build & Integration
We implement both APIs as needed imperative for complex logic, declarative for standard forms tested against Chrome’s origin trial.
04
Eval, Launch & Handover
We run agent evals, fix edge cases, document every tool for your team, and hand over a production-ready implementation.
Industries & Use Cases
Where WebMCP Drives Real Value
Any website with structured user journeys is a candidate. Here are the most impactful applications.
E-Commerce & Retail
Enable AI shopping assistants to filter products, apply discount codes, and complete checkout accurately — every time, boosting conversion rates significantly.
Travel & Hospitality
Let agents handle complex multi-city bookings, date pickers, and passenger details without misinterpreting bespoke UI components.
Healthcare & Appointments
Expose appointment booking and triage forms as structured tools, reducing friction for patients using AI health assistants.
SaaS & Developer Tools
Register diagnostic triggers, settings flows, and onboarding steps as callable tools so power users' AI agents can automate repetitive configuration tasks.
Financial Services
Provide agents with structured access to account tools with confirmation dialogues enforced for sensitive actions like transfers or applications.
Customer Support Portals
Help agents navigate complex support trees and pre-fill ticket fields accurately, reducing resolution time and support overhead.
