List all npm packages available in the platform catalog (not project-specific)
AI agents call list_catalog to retrieve information from Prowpt MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of available npm packages from a centralized catalog. It is purely informational, does not modify any data, execute code, or cause irreversible changes. The blast radius of misuse is minimal—an agent could only retrieve information about available packages, which is not sensitive or harmful.
From the tool's definition Tool name 'list_catalog' and description 'List all npm packages available in the platform catalog' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
List all npm packages available in the platform catalog (not project-specific). It is categorised as a Read tool in the Prowpt MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Prowpt MCP Server MCP server in PolicyLayer and add a rule for list_catalog: 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 Prowpt MCP Server. Nothing to install.
list_catalog 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 list_catalog 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 list_catalog. 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.
list_catalog is provided by the Prowpt MCP Server MCP server (prowptai/prowpt-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
