WHAT IT DOES

What sxo_write does on 0nmcp

AI agents use sxo_write to create or update resources in 0nmcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 0nmcp environment.

RISK

Why sxo_write is rated Medium

The tool creates new blog post content and updates it based on performance feedback. This is a classic Write operation—content creation that can be edited, deleted, or replaced. It does not execute arbitrary code, delete irreversibly, move money, or trigger external system operations beyond content generation.

From the tool's definition Tool name 'sxo_write' and description explicitly state it 'Write an SXO-optimized blog post' and 'learns from the performance of previous posts and improves.' This creates or modifies content (blog posts) reversibly.

RECOMMENDED RULE

The rule that runs sxo_write safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 0nmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For sxo_write, this is the rule to start with:

sxo_write Rate-limited

sxo_write 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.

    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect 0nmcp, apply this rule, and every sxo_write call is checked against it from then on.
