Skip post-deploy trigger sync for self-hosted MCP deployments

[Copilot]

Deployments of self-hosted Python MCP projects to Premium/App Service Plan apps using Secrets auth were failing after zip deploy with host runtime ServiceUnavailable. The failure path came from shared post-deploy trigger synchronization, not from package upload.

• Deployment flow: disable trigger sync for MCP projects

  • Added DisableSyncTriggersForMcpExecuteStep to explicitly set context.syncTriggersPostDeploy = false when context.isMcpProject is true.
  • Priority is set to run before the shared PostDeploySyncTriggersExecuteStep, preventing the host-runtime sync call for MCP deploys.

• Wiring in deploy pipeline

  • Updated deploy.ts to include the new step in innerDeploy(...) optional steps, ahead of remote MCP server registration.

• Coverage

  • Added focused unit tests for the new step:
    • executes only for MCP projects
    • clears syncTriggersPostDeploy when executed

// deploy.ts
await innerDeploy(site, deployFsPath, deployContext, [
  new DisableSyncTriggersForMcpExecuteStep(),
  new CreateRemoteMcpServerExecuteStep()
]);

// DisableSyncTriggersForMcpExecuteStep.ts
public async execute(context: T): Promise<void> {
  context.syncTriggersPostDeploy = false;
}

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• aka.ms
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node scripts/pretest.mjs (dns block)
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
