Can an assistant write a script and run it in the same session?

Yes, with one Apps Script platform caveat: run_script_function executes functions from a deployed script, so the flow is create or update the source, create a deployment with manage_deployment, then invoke. All three steps are tool calls the assistant can chain.

What are bound scripts, and are they supported?

create_script_project creates both standalone projects and scripts bound to a specific Doc, Sheet, or Form — bound scripts are how you add custom behavior to one particular document.

When should I reach for Apps Script instead of a native service?

When the other services don’t expose what you need: custom triggers, Workspace APIs the server doesn’t wrap, or multi-step server-side logic that should run on Google’s infrastructure rather than through a dozen round trips.

Google Apps Script MCP Server

The escape hatch: write, deploy, and execute custom code across Workspace.

Quick start Jump to all 15 tools →

Apps Script is the escape hatch for everything the other eleven services don’t cover. An assistant can create a script project, write or update its source with update_script_content, and execute deployed functions with arguments via run_script_function — custom automation authored and invoked in the same conversation.

The operational tools matter just as much: create_version, list_versions, and manage_deployment handle the versioning lifecycle, generate_trigger_code scaffolds time-driven and event triggers, and list_script_processes and get_script_metrics show what ran, what failed, and how often.

What you can ask

“Write a script that snapshots the on-call sheet every Friday and deploy it”
“Run the syncInventory function against the staging spreadsheet”
“Which script executions failed this week, and why?”
