WebMCP: Your Website Talks to AI Agents
The open standard that makes websites interactive for ChatGPT, Claude, and Perplexity. Not just visible — usable.
What Is WebMCP?
WebMCP stands for Model Context Protocol for the Web — an open standard that defines how AI agents interact with websites. Without WebMCP, an AI can read your website. With WebMCP, it can use your website.
The difference: Today, an AI agent finds your website and reads the text. Tomorrow, it fills out your contact form, books an appointment via Cal.com, or sends an enquiry — directly from the chat. WebMCP makes this leap possible.
Imagine: A user asks ChatGPT for a web developer in Switzerland. Without WebMCP, they get a link. With WebMCP, the agent can directly request a quote, book an appointment, or send a message — without the user ever visiting your website manually.
That is the difference between being found and being useful. WebMCP turns your website into a tool for AI agents — not just another page in the search results.
OpenHermit — WebMCP for Any Website
0gravity built OpenHermit — an open-source library that implements the WebMCP standard. A single script tag makes any website interactive for AI agents.
OpenHermit automatically detects forms and widgets on your page, injects the necessary WebMCP attributes, and enables AI agents to interact. No rebuild, no redesign — just add the script.
For 0gravity clients: OpenHermit is included by default in the Standard and Premium packages. For existing websites, it can be added as a standalone script.
