Governed ability
Delete post meta
aafm/delete-post-metaGuarded write
Delete post meta is a governed ability in Agent Abilities for MCP, a free WordPress plugin that runs an MCP server on your site.
Delete an allowlisted meta key from a post the agent can edit. Removes all values of that key.
How it is governed
The same model as every ability in the plugin, stated for this one.
- Off until you enable it
Like every ability, Delete post meta ships switched off. You turn it on one at a time, and an update never widens access on its own.
- Guarded write
Writes stay conservative, and the plugin re-checks the capability before the call runs.
- Capability gated
A connection only sees Delete post meta if the user you connected can run it, and the plugin checks that capability again before it executes.
- Every call audited
The call is written to the log in your own database, denials included, with the argument keys and the identifiers it touched, never free-text content.
- It can delete
This ability can delete. Where WordPress supports it, items go to Trash and can be restored, and the last administrator can never be removed.
Delete post meta is one of the 26 governed Content abilities. Browse the other Content abilities in the catalog.

Try it with a prompt
Example requests you could paste to your agent.
Remove the old promo_banner meta key from post 142.
Delete the deprecated subtitle_v1 custom field on that page.
Clear the seasonal_tag meta off post 305.
These are illustrative example prompts. The agent runs them as the user you connected, checked against that user's capabilities and written to your audit log.
Frequently asked
Short answers for Delete post meta.
What exactly gets removed?
Delete post meta removes every value stored under that meta key on the post. Only allowlisted keys can be targeted.
Is there a safety net?
Delete post meta is a hard delete, because there is no per-field Trash for meta. The ability stays off until enabled, needs edit access to the post, and is audited.
Why can it not touch image alt text or the featured image?
Alt text lives under `_wp_attachment_image_alt` and the featured image under `_thumbnail_id`. Both are protected meta in stock WordPress and are refused for every caller whatever their role. Clear alt text through update media, and the thumbnail through set featured image or the post's featured_media field. Since 1.7.0 the refusal names the right tool instead of reading as a permission problem.
Governed by default, from the first call.
Delete post meta is off until you enable it, scoped to the user you connect, and logged like everything else. Turn on only what you need.
Every ability off until you enable it, capability-gated on every call.
