MCP server example for edge functions?

Support

Hello!

I saw this great article you published for deploying MCP servers on Netlify: Building MCPs with Netlify | Netlify Developers. This article covers serverless functions, but I was wondering if it is possible to build one that is deployed on edge functions instead. If so, could you please provide boilerplate for that as well?

Thanks!

You can try replacing the NPM module imports to imports from esm.sh and see if it works. For example:

import { StreamableHTTPServerTransport } from "@modelcontextprotocol/sdk/server/streamableHttp.js"

would be:

import { StreamableHTTPServerTransport } from 'https://esm.sh/@modelcontextprotocol/sdk/dist/esm/server/streamableHttp.js'

What’s the advantage/disadvantage of using Edge Functions over Serverless Functions?

Mainly having regional support instead of being stuck to a single location and shorter to none cold starts.

We implemented an MCP server with Netlify Edge Functions. Here it is for those who are interested: docs-site/netlify/edge-functions/mcp.js at main · redpanda-data/docs-site · GitHub

And here’s the blog we posted to announce it: Meet the Redpanda Documentation MCP server
