AI agents call search_assets to retrieve information from Melo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a public catalog to retrieve asset information. It has no side effects—it neither modifies data, executes code, deletes anything, nor involves financial transactions. The read-only nature and public access model make it a straightforward Read category risk with low severity.
From the tool's definition Tool description states 'Search the Roblox Creator Store / Catalog' with 'Public endpoint, no auth required.' The name 'search_assets' and query argument indicate data retrieval without modification.
Attacks that exploit this kind of access
Search the Roblox Creator Store / Catalog. Public endpoint, no auth required. Args: - query (string) - assetType (enum, optional):. It is categorised as a Read tool in the Melo MCP Server, which means it retrieves data without modifying state.
Register the Melo MCP server in PolicyLayer and add a rule for search_assets: 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 Melo. Nothing to install.
search_assets 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 search_assets 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 search_assets. 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.
search_assets is provided by the Melo MCP server (yannyhl/linkedsword-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
