List attachments for a page. Returns name, size, content type, and the relative markdown path to reference each file.
AI agents call list_attachments to retrieve information from Collectives without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves attachment information for a page—a read-only operation with no side effects. It returns metadata (name, size, content type, paths) but does not create, modify, delete, or execute anything. The blast radius of misuse is minimal; an agent could enumerate attachments but cannot alter or access their contents directly through this tool alone.
From the tool's definition Tool name 'list_attachments' and description 'List attachments for a page. Returns name, size, content type, and the relative markdown path to reference each file.' indicates retrieval of attachment metadata without modification or deletion.
Attacks that exploit this kind of access
List attachments for a page. Returns name, size, content type, and the relative markdown path to reference each file. It is categorised as a Read tool in the Collectives MCP Server, which means it retrieves data without modifying state.
Register the Collectives MCP server in PolicyLayer and add a rule for list_attachments: 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 Collectives. Nothing to install.
list_attachments 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_attachments 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_attachments. 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_attachments is provided by the Collectives MCP server (megamaced/nc_collectives-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
