List the bio-link (link-in-bio) pages owned by the workspace. Returns id + slug + custom domain so callers can identify a page before pulling its subscribers via list_biolink_subscribers.
AI agents call list_biolinks to retrieve information from Viraly MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about bio-link pages owned by a workspace. It performs a query operation that returns identifying information (id, slug, custom domain) without creating, modifying, deleting, or triggering external actions. The use case described—identifying a page before performing further reads—confirms it is a simple data retrieval operation with no side effects.
From the tool's definition Tool description states it 'List[s] the bio-link pages' and 'Returns id + slug + custom domain', with the purpose of allowing callers to 'identify a page'.
Attacks that exploit this kind of access
List the bio-link (link-in-bio) pages owned by the workspace. Returns id + slug + custom domain so callers can identify a page before pulling its subscribers via list_biolink_subscribers. It is categorised as a Read tool in the Viraly MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Viraly MCP Server MCP server in PolicyLayer and add a rule for list_biolinks: 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 Viraly MCP Server. Nothing to install.
list_biolinks 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_biolinks 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_biolinks. 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_biolinks is provided by the Viraly MCP Server MCP server (viraly-io/viraly-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
