aafm/acf-update-term-fieldsGuarded write
Update term ACF fields is a governed ability in Agent Abilities for MCP, a free WordPress plugin that runs an MCP server on your site.
Writes ACF field values on a term by field key, each value sanitized for its field type. Requires edit access to that term.
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, Update term ACF fields 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 Update term ACF fields 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.
Update term ACF fields is one of the 7 governed ACF abilities. See the full ACF MCP integration.
