Edge MCP is a toolkit that makes your website operable by an AI agent — not just understandable. Where the Web SDK puts an agent on your page that can talk to visitors and answer questions, Edge MCP lets the agent take actions on your site: search products, update a cart, complete a booking, navigate between pages — using the same operations your website already exposes.
How Edge MCP works
Your website declares which of its operations an agent is permitted to call. The agent, during a live conversation, can then invoke those operations in real time in response to what the user says or does.
For example, on a retail site:
- User: "Do you have this jacket in medium?"
- Agent calls the
searchProductsoperation with the relevant parameters. - Site returns the result.
- Agent responds with live inventory data from the actual site.
This is different from the agent drawing on a static knowledge base. Edge MCP calls real operations on your live site, with real-time data.
Built on the WebMCP standard
Edge MCP is built on WebMCP, an emerging W3C web standard that lets websites expose structured tools and JavaScript functions directly to AI agents. What you expose works with any WebMCP-compatible agent — not just Napster's Omniagent. This means your investment in declaring your site's operations is not locked to any single agent platform.
Web SDK + Edge MCP together
The two are designed to work together and complement each other:
| Web SDK | Edge MCP | |
|---|---|---|
| What it does | Puts the agent on your website — video presence, voice, session lifecycle | Lets the agent operate your website — search, cart, actions |
| What the agent can do | Talk to visitors, answer questions, remember context | Call real operations on your site in real time |
| Required | Yes, for web deployments | Optional — adds agentic action capability |
Together, they provide a much more complete agent experience: the agent can both converse and act.
Getting started
Napster has published an end-to-end guide for combining the Web SDK with Edge MCP: Add an AI Agent to Your Website. Start by copying the one-prompt quickstart — it works with Claude Code, Cursor, Codex, and any tool that supports Agent Skills.

First release
Edge MCP is in its first release. Napster is actively looking for feedback from early integrations to shape where it goes next. Share feedback in the Napster developer community on Discord.
