Set the post excerpt (short summary shown in feeds and search results). Pass an empty string to clear.
AI agents use wp_set_excerpt to create or update resources in Claudaborative Editing — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claudaborative Editing environment.
This tool creates or modifies post excerpt data reversibly. While it affects post visibility in feeds and search results, the operation is not destructive (can be undone or re-set) and does not delete data. It is categorized as Write rather than Execute because it modifies specific post metadata rather than triggering conditional side effects.
From the tool's definition Tool name 'wp_set_excerpt' and description 'Set the post excerpt' explicitly indicates modification of post metadata. Accepts empty string to clear, confirming reversible write semantics.
Documented attack patterns abuse exactly the kind of access wp_set_excerpt gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Claudaborative Editing, and nothing reaches the server without passing your rules. This is the rule we recommend for wp_set_excerpt:
{
"version": "1",
"default": "deny",
"tools": {
"wp_set_excerpt": {
"limits": [
{
"counter": "wp_set_excerpt_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}wp_set_excerpt 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.

Set the post excerpt (short summary shown in feeds and search results). Pass an empty string to clear. It is categorised as a Write tool in the Claudaborative Editing MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Claudaborative Editing MCP server in PolicyLayer and add a rule for wp_set_excerpt: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Claudaborative Editing. Nothing to install.
wp_set_excerpt is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the wp_set_excerpt rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for wp_set_excerpt. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
wp_set_excerpt is provided by the Claudaborative Editing MCP server (pento/claudaborative-editing). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Claudaborative Editing, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
