Agent Harness for WordPress: Docker for AI agents

Q: What is Agent Harness for WordPress?

Agent Harness for WordPress is a local Docker WordPress environment for coding agents. Agents talk to a real site through the official WordPress MCP Adapter and Abilities API. It is not a hosted WordPress product and does not ship its own MCP server or plugin.

Q: Which AI coding agents work with it?

Claude Code, Cursor, and Codex connect over HTTP MCP. Use ./bin/connect for Claude Code, or ./bin/connect --print for the MCP URL and Authorization header other clients need.

Q: Is the WordPress site public?

No. The harness binds WordPress and MariaDB to 127.0.0.1 only. This Netlify page is marketing only and does not expose the MCP endpoint.

Q: How do you reset the local site?

Run ./bin/reset. It destroys the Docker volumes and rebuilds a clean WordPress install. ./bin/setup alone is idempotent and does not wipe content.

What is Agent Harness for WordPress?

Agent Harness for WordPress is a local, disposable WordPress install for AI coding agents. It runs WordPress and MariaDB in Docker on loopback, exposes site abilities through the official WordPress MCP Adapter, and resets with one command. The repo wires the stack; it does not ship an MCP server or plugin of its own.

What you get

A disposable harness, not a hosted WordPress. The MCP server and abilities come from upstream.

Docker

WordPress and MariaDB on loopback only, with pinned images and one-command provision.

MCP Adapter

Three meta-tools: discover abilities, inspect schemas, execute. No invented tool names.

Abilities

MS WordPress Abilities plus core site info on a real local install agents can edit.

Quick start

Needs Docker Compose v2, Git, and Bash.

git clone https://github.com/marcop135/wp-agent-harness.git

./bin/setup
./bin/connect
