create-post · Paragraph MCP: Risk & Policy

WHAT IT DOES

What create-post does on Paragraph MCP

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

WHY IT NEEDS A POLICY

Why create-post needs a policy

This tool creates new posts, which is a reversible write operation. While posts can be created and modified, they are not permanently destroyed by this action alone. The tool is Write rather than Destructive because creation is inherently reversible (posts can be edited or deleted). It is not Execute because it does not run arbitrary code or trigger external operations—it simply adds structured content.

From the tool's definition Tool name 'create-post' and description 'Create a post in your publication' indicate creation of new content that can be modified or deleted later.

Verdict

create-post Rate-limited

create-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.
