An agent decides it needs live data — a service list, a fit score, a lead to submit — and calls a tool by name.
WebMCP
This Site Is Built to Be Read by Agents, Not Just Browsed by Them
How a tool call reaches this site
In a WebMCP-enabled browser, the call runs through document.modelContext, registered on every page load. A remote MCP client calls /api/mcp directly instead.
The tool call hits a REST endpoint under /api/v1, backed by the same GROQ queries and business logic the rest of the site runs on — never a separate content source.
The result — case studies, a fit score, a submitted lead — comes back as structured JSON the agent can act on immediately.
One source of truth
Every tool pulls from the same live content and business logic the rest of the site runs on — there's no separate, out-of-date version for agents.
Who this is for
A few concrete ways people are already putting this to use.
Ask an AI assistant to find the right service for your business — it can pull live details straight from this site instead of guessing.
Have it dig up case studies from a brand like yours, or check your fit before you ever fill out a form.
Let it find the right person on our team to talk to.
When you're ready, have it submit your info directly to our sales team — no new tab, no rebuilding the form.
The tools
Every tool below is live right now, at /api/mcp and in-browser via document.modelContext. This list is generated directly from the registry the tools actually run on, so it can't drift out of date.
*modelContext is only available on Chrome Canary version at the time of writing.

}Questions
A few things worth clarifying before you build against this.
What is WebMCP?
WebMCP (document.modelContext) lets an AI-enabled browser or assistant call tools a website registers, directly — pulling real answers from human.marketing instead of guessing from a stale summary.
How do I use it?
There's nothing to install. If you're browsing with an AI assistant that supports WebMCP, our tools are already available to it. If not, any MCP-compatible agent can reach the same tools directly at /api/mcp.
What can it actually do here?
Look up our services and case studies, check your fit before reaching out, find the right person on our team, search the site, and — once you're ready — submit your info to our sales team.
Why did Human build this?
We think agent-driven discovery is coming for every industry, including our own — see our Agentic Commerce page for our full take. Building WebMCP into our own site is us practicing what we tell clients to prepare for.
Human browsing vs. Agent browsing
A person reads a page, decides what matters, and manually fills out a form.
An agent calls a tool and gets a direct, accurate answer back — and can act on it immediately, including reaching out to our team — without you filling out a thing.
