List guest message threads (conversations) on the connected Hostaway account. Returns a compact Markdown table with conversation id, guest, linked listing/reservation, unread state, and last activity time.
AI agents call list_conversations to retrieve information from Hostaway-mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries conversation metadata without side effects. It is explicitly part of a read-only API and merely returns information about existing conversations. There is no capability to modify, delete, or execute actions. The blast radius of misuse is minimal—an agent could only over-retrieve conversation listings.
From the tool's definition Tool name 'list_conversations' and description stating it 'List[s] guest message threads' and 'Returns a compact Markdown table'. The server is explicitly described as providing '10 read-only tools'.

List guest message threads (conversations) on the connected Hostaway account. Returns a compact Markdown table with conversation id, guest, linked listing/reservation, unread state, and last activity time. It is categorised as a Read tool in the Hostaway-mcp MCP Server, which means it retrieves data without modifying state.
Register the Hostaway- MCP server in PolicyLayer and add a rule for list_conversations: 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 Hostaway-mcp. Nothing to install.
list_conversations 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_conversations 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_conversations. 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_conversations is provided by the Hostaway- MCP server (prosperkartik/hostaway-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
