Book a meeting on a SavvyCal scheduling link for a specific time slot. Use this to: - Book a meeting on behalf of someone - Schedule a meeting at a specific available slot Args: - link_slug (string, required): Scheduling link slug (e.g. "intro-call") — get from savvycal_list_scheduling_link...
Single-target operation
Part of the SavvyCal MCP Server MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use savvycal_create_event to create or modify resources in SavvyCal MCP Server. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call savvycal_create_event repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach SavvyCal MCP Server.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Book a meeting on a SavvyCal scheduling link for a specific time slot. Use this to: - Book a meeting on behalf of someone - Schedule a meeting at a specific available slot Args: - link_slug (string, required): Scheduling link slug (e.g. "intro-call") — get from savvycal_list_scheduling_links - starts_at (string, required): ISO 8601 datetime for the meeting start — must match an available slot from savvycal_get_available_slots - name (string, required): Full name of the attendee being booked - email (string, required): Email address of the attendee - description (string, optional): Optional note or message for the booking Returns: The newly created event with all details including any conferencing join link. Workflow: Use savvycal_list_scheduling_links to find the link slug, then savvycal_get_available_slots to find valid times, then this tool to book.. It is categorised as a Write tool in the SavvyCal MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for savvycal_create_event. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the SavvyCal MCP Server MCP server.
savvycal_create_event is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the savvycal_create_event rule in your Intercept 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 Intercept policy for savvycal_create_event. 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.
savvycal_create_event is provided by the SavvyCal MCP Server MCP server (arturkoter/savvycal-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
