// route-provider: route-proxy's Go half, one binary the node's runtime launches and speaks MCP to over stdio
|
|
// through the Go SDK. It runs the SDK's provider helper that answers the consumers of `route` (issue 792), and serves
|
|
// the module's tools, which read what the proxy keeps on the bus (issue 774, tools.go).
|
|
//
|
|
// stdout is the MCP channel, so everything this module says, it says on stderr.
