Move an existing scheduled post to a new time without re-sending the caption or attachments. Lighter alternative to update_post when you only need to change the schedule. Cannot reschedule already-published posts.
AI agents use reschedule_post to create or update resources in Viraly MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Viraly MCP Server environment.
This is a Write operation because it modifies existing data (the scheduled time of a post) in a reversible manner. It is not Destructive because rescheduling can be undone by rescheduling again. It is not Execute because it doesn't run arbitrary code or external operations—it only changes a date/time field.
From the tool's definition Tool description states 'Move an existing scheduled post to a new time' which modifies post scheduling metadata.
Attacks that exploit this kind of access
Move an existing scheduled post to a new time without re-sending the caption or attachments. Lighter alternative to update_post when you only need to change the schedule. Cannot reschedule already-published posts. It is categorised as a Write tool in the Viraly MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Viraly MCP Server MCP server in PolicyLayer and add a rule for reschedule_post: 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.
reschedule_post 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 reschedule_post 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 reschedule_post. 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.
reschedule_post 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.
