Query another user's public availability by their Temporal Link slug. Returns available time slots for a given date. Use after resolve_identity to find the slug. Requires Platform Mode.
AI agents call query_public_availability to retrieve information from Temporal Cortex Calendar MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
date | string | Yes | Date to query in YYYY-MM-DD format. |
slug | string | Yes | Temporal Link slug (e.g., "jane-doe"). |
timezone | string | null | — | IANA timezone for response times (e.g., "America/New_York"). |
duration_minutes | integer | null | — | Minimum slot length in minutes (default: 30). |
Parameters from the server's own tool schema.
Even though query_public_availability only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
Query another user's public availability by their Temporal Link slug. Returns available time slots for a given date. Use after resolve_identity to find the slug. Requires Platform Mode. It is categorised as a Read tool in the Temporal Cortex Calendar MCP MCP Server, which means it retrieves data without modifying state.
query_public_availability accepts 4 parameters: date, slug, timezone, duration_minutes. Required: date, slug. The full parameter table on this page comes from the server's own tool schema.
Register the Temporal Cortex Calendar MCP server in PolicyLayer and add a rule for query_public_availability: 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 Temporal Cortex Calendar MCP. Nothing to install.
query_public_availability 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 query_public_availability 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 query_public_availability. 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.
query_public_availability is provided by the Temporal Cortex Calendar MCP server (temporal-cortex/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
