manage_protected_ranges
Manages protections that stop other editors from changing cells. action=add protects a grid range (or a named range via named_range_id; a range with only sheet_id protects the whole sheet): warning_only=true merely warns before edits, otherwise only the listed editor_users/editor_groups (emails) ...

What manage_protected_ranges does on Mcp Google Sheets
AI agents use manage_protected_ranges to create or update resources in Mcp Google Sheets, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Google Sheets environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
range | object | — | add: the cells to protect. |
action | string | Yes | What to do with the protections. |
description | string | — | Label shown in the Sheets UI protections list. |
editor_users | array | — | Emails of users allowed to edit the protected cells. |
warning_only | boolean | — | true = anyone can still edit after a warning; false = only the listed editors. |
editor_groups | array | — | Emails of Google Groups allowed to edit. |
named_range_id | string | — | add: protect a named range instead of a grid range. |
spreadsheet_id | string | Yes | The spreadsheet id — the long id from the URL (docs.google.com/spreadsheets/d/<spreadsheetId>/edit) or from create_spreadsheet / search_spreadsheets output. |
protected_range_id | integer | — | update/delete: the protection's id from get_spreadsheet or the add reply. |

The rule that runs manage_protected_ranges safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Google Sheets, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For manage_protected_ranges, this is the rule to start with:
manage_protected_ranges stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Google Sheets, apply this rule, and every manage_protected_ranges call is checked against it from then on.
Questions about manage_protected_ranges
Manages protections that stop other editors from changing cells. action=add protects a grid range (or a named range via named_range_id; a range with only sheet_id protects the whole sheet): warning_only=true merely warns before edits, otherwise only the listed editor_users/editor_groups (emails) plus the owner may edit — note the calling user is NOT added automatically. Returns the new protectedRangeId in the replies. action=update changes description/warning_only/editors of an existing protection (protected_range_id required; provided fields replace the old values). action=delete removes the protection — the cells and data stay, but anyone with edit access can change them again. Find existing protectedRangeIds via get_spreadsheet. It is categorised as a Write tool in the Mcp Google Sheets MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
manage_protected_ranges accepts 9 parameters: range, action, description, editor_users, warning_only, editor_groups, named_range_id, spreadsheet_id, protected_range_id. Required: action, spreadsheet_id. The full parameter table on this page comes from the server's own tool schema.
Register the Mcp Google Sheets MCP server in PolicyLayer and add a rule for manage_protected_ranges: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp Google Sheets. Nothing to install.
manage_protected_ranges is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the manage_protected_ranges rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for manage_protected_ranges. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
manage_protected_ranges is provided by the Mcp Google Sheets MCP server (@a1-x-tech/mcp-google-sheets). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
