# What is WebMCP?

> An emerging, still-early standard that would let an autonomous AI agent discover and call actions directly on a website it visits on its own, without a business or developer configuring a connection ahead of time.

## In short

- WebMCP would let an autonomous agent discover and act on a website with no connection pre-configured.
- It's still early and unproven, and only solves the connection job, not identity or payment.

Good for: An agent finding a business on its own, with no connection configured in advance. Not good for: Identity or payment, and not mature enough yet to treat as settled.

Unlike MCP, which needs a server set up in advance, WebMCP's aim is letting an agent that finds a business by itself, not one a human pointed it at, work out what it can do there. How mature the spec is, and how widely it'll be adopted, isn't settled yet. It's a genuinely useful answer to a web that wasn't built for agents, not the same thing as identity, payment or checkout, which still need separate protocols on top of it.

## Good for

An agent finding a business on its own, with no connection configured in advance.

## Not good for

Identity or payment, and not mature enough yet to treat as settled.

## Act on this

- [Check whether an agent can buy from you](https://selfe.ai/agentic-commerce/buyability-check) — the free readiness scan.
- [Discover venues](https://selfe.ai/api/registry/discover) — `POST`, semantic browse across the registry.
- [Match a bookable answer](https://selfe.ai/api/registry/match) — `POST` with dates and party size.
- [Verify Selfe's identity](https://selfe.ai/.well-known/did.json) — `did:web:selfe.ai`.
- [Agent card](https://selfe.ai/.well-known/agent-card.json) — how to connect over A2A or MCP.
