AI agents call get_catalyst_component to retrieve information from Next Js Tailwind Assistant without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though get_catalyst_component only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Retrieve the TypeScript source code for a specific Catalyst UI component. Components include forms (button, checkbox, input, etc.), navigation (navbar, sidebar, dropdown), layout (divider, heading), feedback (alert, badge, dialog), and data display (avatar, table, pagination). All components are production-ready TypeScript React components with Tailwind styling and Headless UI integration.. It is categorised as a Read tool in the Next Js Tailwind Assistant MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for get_catalyst_component. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Next Js Tailwind Assistant MCP server.
get_catalyst_component 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_catalyst_component 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.
Set action: deny in the Intercept policy for get_catalyst_component. 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_catalyst_component is provided by the Next Js Tailwind Assistant MCP server (CaullenOmdahl/nextjs-react-tailwind-assistant). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
