Find pages that link to the given page. Scans the linkedPageIds field on all pages in the Collective.
AI agents call get_backlinks 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 returns metadata about page relationships (backlinks) without creating, modifying, deleting, or executing any operations. It has no side effects and poses minimal security risk as it only retrieves information about existing internal link structure within the Nextcloud Collectives instance.
From the tool's definition Tool name 'get_backlinks' and description 'Find pages that link to the given page' indicate a query operation that retrieves existing link data without modification.
Attacks that exploit this kind of access
Find pages that link to the given page. Scans the linkedPageIds field on all pages in the Collective. 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 get_backlinks: 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.
get_backlinks 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_backlinks 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_backlinks. 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_backlinks 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.
