WordPress MCP is briefly making agent access cheaper to try. The useful lesson is not “turn everything on.” It is “enable only the few actions your workflow can justify.”

WordPress.com now documents MCP access for AI agents, including a temporary path for self-hosted WordPress sites connected through Jetpack: no Jetpack plan is required through November 30, 2026. That lowers the price of experimentation. It does not lower the cost of a bad edit, an accidental deletion, or a publishing system with no accountable boundary.

Free access is not free authority

The WordPress.com setup deserves a careful read because it makes the tradeoff visible. Enabling MCP turns on both Read and Write tool groups by default. Those write tools can create, edit, or delete content. The same documentation also supplies the escape hatch: tool groups can be customized, individual tools can be switched off, settings can be limited to one site, and site-level limits override account-wide defaults.

That is the pattern small publishers should copy even when they are not using WordPress.com. Start with the smallest useful role: perhaps let an agent read a selected set of posts, create a draft in one category, and upload one image. Do not give it site settings, user management, or deletion tools because those happen to be available.

Make the publishing step special

Publishing is an external claim in your name. It deserves different treatment from research or drafting. WordPress.com can ask for confirmation before writes and records agent changes in its Activity Log. Cloudflare’s agent documentation makes the broader engineering case: publishing and email sending are examples of actions that benefit from a human-in-the-loop approval gate. A long-running workflow can pause, wait for approval, and then either proceed or stop.

This is not an argument against automation. It is an argument for making authority explicit. Let the agent handle the repetitive parts: find sources, compare drafts, format links, prepare alt text, and assemble a preview. Reserve the irreversible or reputational action for a separate tool, a confirmation, or a predictable schedule with a narrow scope.

Why this is also the low-cost choice

Least privilege saves time as well as reducing risk. A narrow agent needs fewer tools, less context, and less cleanup. It makes failures smaller and easier to diagnose. A recent research preprint on automated educational publishing described a similar structure: deterministic scripts, rubric-bound model steps, open-ended agent phases, and human approval gates. That design treats production as a sequence of checkpoints rather than one oversized generation call.

If you want to use the temporary MCP access window, a good first test is deliberately boring: enable a single site, allow reading and draft creation, leave publishing behind a confirmation, and inspect the activity log after each run. Cheap access is valuable. Cheap mistakes are better.
