Return the named color slots from word/theme/theme1.xml.
AI agents call get_theme_colors to retrieve information from Docx without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves theme color information from a Word document's XML structure. 'Return' and 'get' are read-only operations. No document state is altered, no code is executed, and no data is deleted or created. The low severity reflects that color theme data is non-sensitive structural information with minimal blast radius if exposed to an AI agent.
From the tool's definition Tool name 'get_theme_colors' and description 'Return the named color slots from word/theme/theme1.xml' indicate a retrieval operation that queries document theme data without modification or side effects.
Documented attack patterns abuse exactly the kind of access get_theme_colors gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Docx, and nothing reaches the server without passing your rules. This is the rule we recommend for get_theme_colors:
{
"version": "1",
"default": "deny",
"tools": {
"get_theme_colors": {}
}
}get_theme_colors is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Return the named color slots from word/theme/theme1.xml. It is categorised as a Read tool in the Docx MCP Server, which means it retrieves data without modifying state.
Register the Docx MCP server in PolicyLayer and add a rule for get_theme_colors: 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 Docx. Nothing to install.
get_theme_colors is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_theme_colors 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 get_theme_colors. 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.
get_theme_colors is provided by the Docx MCP server (securityronin/docx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Docx, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
