Publish or schedule a previously previewed social media post via Late. Requires a saved draft from preview_social_post. Optionally schedule for a future time.
AI agents use publish_social_post to create or update resources in Solar2D MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Solar2D MCP Server environment.
Publishing social media posts creates/modifies data on external platforms but is reversible (posts can be deleted, edited, or unscheduled). This is fundamentally a Write operation rather than Execute because the tool's action is scoped to publishing pre-previewed content rather than running arbitrary code or commands.
From the tool's definition Tool description states it 'Publish or schedule a previously previewed social media post' and can optionally schedule for future time. This creates new content on social media platforms, a reversible write operation.
Documented attack patterns abuse exactly the kind of access publish_social_post gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Solar2D MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for publish_social_post:
{
"version": "1",
"default": "deny",
"tools": {
"publish_social_post": {
"limits": [
{
"counter": "publish_social_post_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}publish_social_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.

Publish or schedule a previously previewed social media post via Late. Requires a saved draft from preview_social_post. Optionally schedule for a future time. It is categorised as a Write tool in the Solar2D MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Solar2D MCP Server MCP server in PolicyLayer and add a rule for publish_social_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 Solar2D MCP Server. Nothing to install.
publish_social_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 publish_social_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 publish_social_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.
publish_social_post is provided by the Solar2D MCP Server MCP server (sensiblecoder/solar2d-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Solar2D MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
