PromptWire

ProcessWire ↔ Cursor MCP Bridge for AI-assisted development.

Disclaimer: This is a development tool. It gives an AI agent direct access to create, edit, download, and delete pages, fields, templates, and files via the ProcessWire API. Always have backups in place. Do not use this on client-facing sites or any environment where you cannot accept the risk of data loss or corruption. This module is provided as-is, with no warranty. By using it you accept all associated risk.

Introduction

PromptWire connects your ProcessWire CMS to Cursor IDE via the Model Context Protocol, giving AI agents direct read/write access to your site's structure, content, and files. It ships with 30+ specialised tools for site inspection, content sync, schema management, page creation, and cross-environment deployment.

Just describe what you want in plain language:

"Build a blog section at /blog/ with an index page and three sample posts. Posts should have a title, body, summary, and publish date. Dry-run everything first."

"Pull our About page, rewrite the body to be more concise, and push the changes to both local and production."

"Compare our local schema against production and flag anything that could cause problems if we pushed."

The agent reads your site's schema, selects the right tools, sequences the operations, and previews everything before applying. No tool names to memorise — see the Prompt recipes for more examples.

The module has two parts:

• Cursor MCP integration — describe what you want and the AI agent builds it: creates templates, fields, pages, and content, pushes changes between environments, and compares schemas. All from Cursor chat.
• Admin dashboard — a visual sync status UI inside the PW admin. See which pages are synced, view diffs, pull and push individual or bulk pages — all without leaving the browser.

Installation

1. Install the ProcessWire module

Clone or download this repo directly into your ProcessWire site/modules/ folder as PromptWire:

git clone https://github.com/PeterKnightDigital/PromptWire-MCP.git site/modules/PromptWire

Or download the zip, extract, and rename the folder to PromptWire inside site/modules/.

Then in ProcessWire admin: Modules → Refresh → Install PromptWire.

The admin dashboard (ProcessPromptWireAdmin) is installed automatically — you'll find it under Setup → PromptWire Admin.

2. Build the MCP server

cd site/modules/PromptWire/mcp-server
npm install
npm run build

3. Configure Cursor

Create or edit .cursor/mcp.json in your project root:

{
  "mcpServers": {
    "PromptWire: My Site (Local)": {
      "command": "node",
      "args": ["/path/to/pw-site/site/modules/PromptWire/mcp-server/dist/index.js"],
      "env": {
        "PW_PATH": "/path/to/your/processwire/site",
        "PHP_PATH": "/path/to/php"
      }
    }
  }
}

Setting	What it is
"PromptWire: My Site (Local)"	A label of your choice — this name appears in Cursor's MCP panel
command	The runtime that starts the MCP server. Always "node"
args	Absolute path to the compiled MCP server entry point (mcp-server/dist/index.js) inside your PromptWire module directory
PW_PATH	Absolute path to your ProcessWire install root (the directory containing site/ and wire/)
PHP_PATH	Absolute path to your PHP binary. Optional if php is already on your system PATH

Finding your PHP path: Run which php in your terminal. Common locations:

• MAMP: /Applications/MAMP/bin/php/php8.x.x/bin/php
• Homebrew: /opt/homebrew/bin/php or /usr/local/bin/php
• XAMPP: /Applications/XAMPP/bin/php
• System (macOS): /usr/bin/php

If which php returns the correct version (8.0+), you can omit PHP_PATH entirely.

4. (Optional) Remote site access

For pushing content to a production site, see the Remote setup guide.

pw_sync_reconcile	Fix path drift, detect orphans, reconcile sync directories
pw_validate_refs	Validate page references across synced content

Page management

Tool	Description
pw_page_new	Scaffold a new page locally (creates page.yaml + page.meta.json)
pw_page_init	Initialise or repair page.meta.json for a sync directory
pw_page_publish	Publish a scaffolded page to ProcessWire (local, remote, or both)
pw_pages_publish	Bulk publish all new page scaffolds in a directory

Schema sync

Tool	Description
pw_schema_pull	Pull field and template schema from a PW site into local files
pw_schema_push	Push local schema files to a PW site (creates/updates fields and templates)
pw_schema_diff	Diff local schema files against the live site
pw_schema_compare	Compare schemas between two sites (e.g. local vs production)
pw_list_sites	List configured remote sites from .pw-sync/sites/

File sync

Tool	Description
pw_file_sync	Sync file/image field content between local and remote

Repeater Matrix

Tool	Description
pw_matrix_info	Get matrix field structure (types, fields, labels)
pw_matrix_add	Add a new item to a repeater matrix field

For detailed parameters and examples, see the Tools reference.

Admin dashboard

PromptWire includes a visual dashboard in the ProcessWire admin under Setup → PromptWire Admin. It installs automatically alongside the main module.

The dashboard shows your full page tree with sync status badges (Clean, File Newer, Wire Newer, Conflict, Untracked), per-row actions (Wire to File, File to Wire, View YAML), template and status filters, and bulk operations for multi-page sync.

For a full walkthrough, see the Admin dashboard guide.
