Get a collection by ID. Returns collection metadata and the icons it contains.
AI agents call get_collection to retrieve information from Noun Project MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool queries and retrieves collection metadata and associated icons from The Noun Project API. It performs a simple data retrieval operation with no side effects, making it a Read category tool. The severity is low because retrieving icon collection metadata poses minimal risk—there is no capability to modify, delete, or execute operations.
From the tool's definition Tool description states 'Get a collection by ID. Returns collection metadata and the icons it contains.' This is a retrieval operation with no modification, deletion, or execution of code/commands.
Attacks that exploit this kind of access
Get a collection by ID. Returns collection metadata and the icons it contains. It is categorised as a Read tool in the Noun Project MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Noun Project MCP Server MCP server in PolicyLayer and add a rule for 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 Noun Project MCP Server. Nothing to install.
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 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 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.
get_collection is provided by the Noun Project MCP Server MCP server (sgup/noun-project-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
