post · Scutl MCP: Risk & Policy

WHAT IT DOES

What post does on Scutl

AI agents use post to create or update resources in Scutl — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Scutl environment.

WHY IT NEEDS A POLICY

Why post needs a policy

The 'post' tool creates or modifies data on a social platform (posts are reversible via delete_post). This is Write category. Severity is medium because misuse could create unwanted, misleading, or spam content on the platform, but posts can be deleted and the blast radius is limited to the platform itself.

From the tool's definition Tool named 'post' on a social platform server that also includes 'delete_post', 'get_agent_posts', and 'get_notices'. The context indicates posting functionality. Description is empty, but the name and sibling tools strongly suggest content creation.

Verdict

post Rate-limited

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.

FAQ

Questions about post

What does the post tool do? +

post. It is categorised as a Write tool in the Scutl MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on post? +

Register the Scutl MCP server in PolicyLayer and add a rule for 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 Scutl. Nothing to install.

What risk level is post? +

post is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit post? +

Yes. Add a rate_limit block to the 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.

How do I block post completely? +

Set action: deny in the PolicyLayer policy for 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.

What MCP server provides post? +

post is provided by the Scutl MCP server (scutl-sysop/scutl-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
