Search Shadcn Space blocks using keywords or tags. Agents can use this to find relevant blocks when building a page based on user requirements or content type.
AI agents call searchBlocks 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 tool retrieves and filters existing block components based on search criteria. It is a read-only operation analogous to search or list functions. Even in a misuse scenario, an AI agent could only retrieve information about available UI components, with no ability to modify, delete, install, or execute code. The blast radius is minimal.
From the tool's definition Tool name 'searchBlocks' and description states 'Search Shadcn Space blocks using keywords or tags' — a pure query operation with no side effects. No data creation, modification, deletion, or external execution occurs.
Attacks that exploit this kind of access
Search Shadcn Space blocks using keywords or tags. Agents can use this to find relevant blocks when building a page based on user requirements or content type. 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 searchBlocks: 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.
searchBlocks 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 searchBlocks 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 searchBlocks. 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.
searchBlocks 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.
