It is categorised as a Write tool in the The Latent Space MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the The Latent Space MCP server in PolicyLayer and add a rule for post_lounge_message: 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 The Latent Space. Nothing to install.
post_lounge_message 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 post_lounge_message 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.
