What update_theme does on Doit
AI agents use update_theme to create or update resources in Doit, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Doit environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
id | string | — | The ID of the theme to update. |
name | string | — | Case-insensitive substring search across all custom themes. Multiple matches return an ambiguity error listing names; id takes precedence. |
colors | object | — | New color palette for the theme. Provide both light and dark arrays. |
newName | string | — | New display name for the theme (1-200 characters). Omit to preserve. |
primaryColor | string | — | New primary color: #RGB, #RRGGBB or #RRGGBBAA. Omit to preserve. |
Parameters from the server's own tool schema.
Why update_theme is rated Medium
An AI agent can call update_theme faster than any human can review: one bad instruction and it creates or modifies resources in Doit by the hundred, each call as confident as the last.

The rule that runs update_theme safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Doit, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For update_theme, this is the rule to start with:
update_theme 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 Doit, apply this rule, and every update_theme call is checked against it from then on.
Questions about update_theme
Use this when the user wants to modify an existing custom color theme — rename it, change its primary color, or update its color palette. Accepts either the theme ID or a partial name match across all custom themes; ambiguous matches return an error, and id takes precedence. Requires Cloud Analytics Admin; preset themes cannot be updated. Changes apply immediately to all users who have this theme active. Omitted fields are preserved; colors replaces both palettes. Create new themes with create_custom_theme; change the current user's active theme with set_active_theme. It is categorised as a Write tool in the Doit MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
update_theme accepts 5 parameters: id, name, colors, newName, primaryColor. The full parameter table on this page comes from the server's own tool schema.
Register the Doit MCP server in PolicyLayer and add a rule for update_theme: 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 Doit. Nothing to install.
update_theme 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 update_theme 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 update_theme. 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.
update_theme is provided by the Doit MCP server (@doitintl/doit-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
