set_theme

// WHEN AI AGENTS USE THIS TOOL

AI agents use set_theme to create or modify resources in Weavely AI Forms & Surveys. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

// WHY ENFORCE A POLICY ON SET_THEME

Without a policy, an AI agent could call set_theme repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Weavely AI Forms & Surveys.

// RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the set_theme tool do? +

Set the form's visual theme. Choose colors, fonts, layout, and component styles that match the form's topic and tone. Be creative — pick a cohesive palette. Only send what you want to change — unset properties keep their current values. COLORS (all hex values): - primary: main accent color (buttons, highlights) - background: page background - text: general body text - question: question/label text - answer: user input text - secondary: secondary UI elements - surface: input field backgrounds - border: input borders, dividers - error: validation error color FONT: - family: global font family shorthand (Google Fonts compatible: Inter, Poppins, Playfair Display, Space Grotesk, DM Sans, Lora, etc.) - text: { size: "16px", family: "Inter" } - headings: { size: "32px", family: "Playfair Display" } LAYOUT types: - "under": questions stacked vertically (default) - "left": labels left, inputs right - "right": labels right, inputs left - "clean": minimal, no visual separators - "over": background image with overlay - "through": full-bleed background COMPONENTS: - form: { variables: { gap: "30px", maxWidth: "700px", textAlign: "left" } } - input: { preset: "default" | "square" } - button: { preset: "default" | "square", hoverAnimation: { preset: "default" | "grow" } } - question: { variables: { fontWeight: "500" } }. It is categorised as a Write tool in the Weavely AI Forms & Surveys MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on set_theme? +

Add a rule in your Intercept YAML policy under the tools section for set_theme. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Weavely AI Forms & Surveys MCP server.

What risk level is set_theme? +

set_theme is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit set_theme? +

Yes. Add a rate_limit block to the set_theme rule in your Intercept 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.

How do I block set_theme completely? +

Set action: deny in the Intercept policy for set_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.

What MCP server provides set_theme? +

set_theme is provided by the Weavely AI Forms & Surveys MCP server (florian/weavely). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
