install-blocks

// WHEN AI AGENTS USE THIS TOOL

AI agents use install-blocks to create or modify resources in Shadcn UI Component Reference Server. 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 INSTALL-BLOCKS

Without a policy, an AI agent could call install-blocks 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 Shadcn UI Component Reference Server.

// RECOMMENDED POLICY

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

// FAQ

What does the install-blocks tool do? +

install-blocks. It is categorised as a Write tool in the Shadcn UI Component Reference Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on install-blocks? +

Add a rule in your Intercept YAML policy under the tools section for install-blocks. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Shadcn UI Component Reference Server MCP server.

What risk level is install-blocks? +

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

Can I rate-limit install-blocks? +

Yes. Add a rate_limit block to the install-blocks 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 install-blocks completely? +

Set action: deny in the Intercept policy for install-blocks. 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 install-blocks? +

install-blocks is provided by the Shadcn UI Component Reference Server MCP server (heilgar/shadcn-ui-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Let agents act without letting them run wild.
