Returns the official installation command for a specific Shadcn Space block. Agents can use this to add a block to the project automatically before customizing it.
AI agents call getBlockInstall to retrieve information from Shadcn Space MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read operation that queries and retrieves information (an installation command string). While the command itself could be used to modify a project if executed by an agent, the tool only provides the data—it does not execute, write to, or modify the project. The agent would need a separate execution capability to actually run the command.
From the tool's definition Tool returns an installation command for a shadcn/ui block—it retrieves and provides instructions without executing them or modifying the project. The description states it 'returns' the command, not that it executes or installs it.
Attacks that exploit this kind of access
Returns the official installation command for a specific Shadcn Space block. Agents can use this to add a block to the project automatically before customizing it. It is categorised as a Read tool in the Shadcn Space MCP MCP Server, which means it retrieves data without modifying state.
Register the Shadcn Space MCP server in PolicyLayer and add a rule for getBlockInstall: 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 Shadcn Space MCP. Nothing to install.
getBlockInstall 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 getBlockInstall 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 getBlockInstall. 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.
getBlockInstall is provided by the Shadcn Space MCP server (shadcnspace/shadcnspace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
