AI agents use rednote_generate_post to create or update resources in Rednote Analyzer — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Rednote Analyzer environment.
This tool creates new content (posts) on a social media platform, which is a reversible write operation. Severity is medium because misuse could generate spam, misinformation, or unauthorized content on a major social platform affecting many users, but the operation itself is not destructive or financial.

PolicyLayer is an MCP gateway — it sits between your AI agents and Rednote Analyzer, and nothing reaches the server without passing your rules. This is the rule we recommend for rednote_generate_post:
{
"version": "1",
"default": "deny",
"tools": {
"rednote_generate_post": {
"limits": [
{
"counter": "rednote_generate_post_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}rednote_generate_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.
