AI agents use update_scheduled_post to create or update resources in LinkedIn Intelligence MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your LinkedIn Intelligence MCP Server environment.
This tool modifies a scheduled LinkedIn post's content, timing, or settings before publication. While reversible (a Write operation, not Destructive), it has high severity because an AI agent could unintentionally modify posts scheduled for significant announcements, potentially damaging professional reputation or business communications.
From the tool's definition Tool name 'update_scheduled_post' and description 'Update a scheduled post' indicate modification of existing scheduled content.

PolicyLayer is an MCP gateway — it sits between your AI agents and LinkedIn Intelligence MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for update_scheduled_post:
{
"version": "1",
"default": "deny",
"tools": {
"update_scheduled_post": {
"limits": [
{
"counter": "update_scheduled_post_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_scheduled_post stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
