support for http://$GATEWAY_URL/mcp/<some-mcp> such http://$GATEWAY_URL/mcp/context7?

[Dericko681]

I am working with mcp servers in a kubernetes cluster with the envoy stack. I have deployed the envoy stack from https://aigateway.envoyproxy.io/docs/getting-started/prerequisites and using the mcp config guide from https://github.com/envoyproxy/ai-gateway/blob/main/examples/mcp/mcp_example.yaml

I am using the mcp inspector for testing.

Envoy service is port-forwarded to local host and this works

But for security reasons, I wish to access each mcp server via a path like npx @modelcontextprotocol/inspector@0.16.8 --cli "$GATEWAY_URL/mcp/context7" --method tools/list or npx @modelcontextprotocol/inspector@0.16.8 --cli "$GATEWAY_URL/github-mcp" --method tools/list

Is there support for this in envoy and how i achieve this?

Are you asking for a per backend url? Like directly per server? Instead of or in addition to the aggregated?

[Dericko681]

No @codefromthecrypt I am asking about envoy routing requests to an mcp backend via sse
So say I have deployed brave-search which uses sse
I have tested it with mcp inspector, sending a request directly to the brave search service successfully lists the tools but via envoy returns 400 error
Does envoy implement the double request cycle required to initiate a connection via sse?

first request(GET) returns session id and envoy uses it over the second request?
