# Migrating to `Options{}` for MCP Service Construction
|
|
|
|
## Before (functional options)
|
|
|
|
```go
|
|
svc, err := mcp.New(
|
|
mcp.WithWorkspaceRoot("/path/to/project"),
|
|
mcp.WithProcessService(processSvc),
|
|
mcp.WithWSHub(hub),
|
|
mcp.WithSubsystem(brainSub),
|
|
mcp.WithSubsystem(ideSub),
|
|
)
|
|
```
|
|
|
|
## After (`Options{}` DTO)
|
|
|
|
```go
|
|
svc, err := mcp.New(mcp.Options{
|
|
WorkspaceRoot: "/path/to/project",
|
|
ProcessService: processSvc,
|
|
WSHub: hub,
|
|
Subsystems: []mcp.Subsystem{
|
|
brainSub,
|
|
ideSub,
|
|
},
|
|
})
|
|
```
|
|
|
|
## Notification helpers
|
|
|
|
```go
|
|
// Broadcast to all MCP sessions.
|
|
svc.SendNotificationToAllClients(ctx, "info", "build", map[string]any{
|
|
"event": "build.complete",
|
|
"repo": "go-io",
|
|
})
|
|
|
|
// Broadcast a named channel event.
|
|
svc.ChannelSend(ctx, "build.complete", map[string]any{
|
|
"repo": "go-io",
|
|
"status": "passed",
|
|
})
|
|
|
|
// Send to one session.
|
|
for session := range svc.Sessions() {
|
|
svc.ChannelSendToSession(ctx, session, "agent.status", map[string]any{
|
|
"state": "running",
|
|
})
|
|
}
|
|
```
