AI agents call mobbin_get_collection to retrieve information from Mobbin without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays saved design inspiration items from a Mobbin collection. It performs no mutations, executions, deletions, or financial operations. The operation is purely informational with no blast radius from misuse — an agent could only read design data that is either public or already accessible to the authenticated user.
From the tool's definition Tool description states 'Get the items saved inside a specific Mobbin collection' — a retrieval operation with no modification or side effects. Verb 'Get' indicates query/fetch semantics.
Attacks that exploit this kind of access
Get the items saved inside a specific Mobbin collection (apps, screens, and/or flows). It is categorised as a Read tool in the Mobbin MCP Server, which means it retrieves data without modifying state.
Register the Mobbin MCP server in PolicyLayer and add a rule for mobbin_get_collection: 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 Mobbin. Nothing to install.
mobbin_get_collection 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 mobbin_get_collection 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 mobbin_get_collection. 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.
mobbin_get_collection is provided by the Mobbin MCP server (mobbin-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
